Introduction - - SSH is a protocol for secure remote login and other secure network - services over an insecure network. It consists of three major - components: - o The Transport Layer Protocol [SSH-TRANS] provides server - authentication, confidentiality, and integrity. It may optionally - also provide compression. The transport layer will typically be - run over a TCP/IP connection, but might also be used on top of any - other reliable data stream. - o The User Authentication Protocol [SSH-USERAUTH] authenticates the - client-side user to the server. It runs over the transport layer - protocol. - o The Connection Protocol [SSH-CONNECT] multiplexes the encrypted - tunnel into several logical channels. It runs over the user - authentication protocol. - - The client sends a service request once a secure transport layer - connection has been established. A second service request is sent - after user authentication is complete. This allows new protocols to - be defined and coexist with the protocols listed above. - - The connection protocol provides channels that can be used for a wide - range of purposes. Standard methods are provided for setting up - secure interactive shell sessions and for forwarding ("tunneling") - arbitrary TCP/IP ports and X11 connections. - -3. Specification of Requirements - - All documents related to the SSH protocols shall use the keywords - "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", - "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" to describe - requirements. They are to be interpreted as described in [RFC2119]. - -4. Architecture - - - - - -Ylonen & Moffat Expires March 31, 2004 [Page 3] - -Internet-Draft SSH Protocol Architecture Oct 2003 - - -4.1 Host Keys - - Each server host SHOULD have a host key. Hosts MAY have multiple - host keys using multiple different algorithms. Multiple hosts MAY - share the same host key. If a host has keys at all, it MUST have at - least one key using each REQUIRED public key algorithm (DSS - [FIPS-186]). - - The server host key is used during key exchange to verify that the - client is really talking to the correct server. For this to be - possible, the client must have a priori knowledge of the server's - public host key. - - Two different trust models can be used: - o The client has a local database that associates each host name (as - typed by the user) with the corresponding public host key. This - method requires no centrally administered infrastructure, and no - third-party coordination. The downside is that the database of - name-to-key associations may become burdensome to maintain. - o The host name-to-key association is certified by some trusted - certification authority. The client only knows the CA root key, - and can verify the validity of all host keys certified by accepted - CAs. - - The second alternative eases the maintenance problem, since - ideally only a single CA key needs to be securely stored on the - client. On the other hand, each host key must be appropriately - certified by a central authority before authorization is possible. - Also, a lot of trust is placed on the central infrastructure. - - The protocol provides the option that the server name - host key - association is not checked when connecting to the host for the first - time. This allows communication without prior communication of host - keys or certification. The connection still provides protection - against passive listening; however, it becomes vulnerable to active - man-in-the-middle attacks. Implementations SHOULD NOT normally allow - such connections by default, as they pose a potential security - problem. However, as there is no widely deployed key infrastructure - available on the Internet yet, this option makes the protocol much - more usable during the transition time until such an infrastructure - emerges, while still providing a much higher level of security than - that offered by older solutions (e.g. telnet [RFC-854] and rlogin - [RFC-1282]). - - Implementations SHOULD try to make the best effort to check host - keys. An example of a possible strategy is to only accept a host key - without checking the first time a host is connected, save the key in - a local database, and compare against that key on all future - - - -Ylonen & Moffat Expires March 31, 2004 [Page 4] - -Internet-Draft SSH Protocol Architecture Oct 2003 - - - connections to that host. - - Implementations MAY provide additional methods for verifying the - correctness of host keys, e.g. a hexadecimal fingerprint derived from - the SHA-1 hash of the public key. Such fingerprints can easily be - verified by using telephone or other external communication channels. - - All implementations SHOULD provide an option to not accept host keys - that cannot be verified. - - We believe that ease of use is critical to end-user acceptance of - security solutions, and no improvement in security is gained if the - new solutions are not used. Thus, providing the option not to check - the server host key is believed to improve the overall security of - the Internet, even though it reduces the security of the protocol in - configurations where it is allowed. - -4.2 Extensibility - - We believe that the protocol will evolve over time, and some - organizations will want to use their own encryption, authentication - and/or key exchange methods. Central registration of all extensions - is cumbersome, especially for experimental or classified features. - On the other hand, having no central registration leads to conflicts - in method identifiers, making interoperability difficult. - - We have chosen to identify algorithms, methods, formats, and - extension protocols with textual names that are of a specific format. - DNS names are used to create local namespaces where experimental or - classified extensions can be defined without fear of conflicts with - other implementations. - - One design goal has been to keep the base protocol as simple as - possible, and to require as few algorithms as possible. However, all - implementations MUST support a minimal set of algorithms to ensure - interoperability (this does not imply that the local policy on all - hosts would necessary allow these algorithms). The mandatory - algorithms are specified in the relevant protocol documents. - - Additional algorithms, methods, formats, and extension protocols can - be defined in separate drafts. See Section Algorithm Naming (Section - 6) for more information. - -4.3 Policy Issues - - The protocol allows full negotiation of encryption, integrity, key - exchange, compression, and public key algorithms and formats. - Encryption, integrity, public key, and compression algorithms can be - - - -Ylonen & Moffat Expires March 31, 2004 [Page 5] - -Internet-Draft SSH Protocol Architecture Oct 2003 - - - different for each direction. - - The following policy issues SHOULD be addressed in the configuration - mechanisms of each implementation: - o Encryption, integrity, and compression algorithms, separately for - each direction. The policy MUST specify which is the preferred - algorithm (e.g. the first algorithm listed in each category). - o Public key algorithms and key exchange method to be used for host - authentication. The existence of trusted host keys for different - public key algorithms also affects this choice. - o The authentication methods that are to be required by the server - for each user. The server's policy MAY require multiple - authentication for some or all users. The required algorithms MAY - depend on the location where the user is trying to log in from. - o The operations that the user is allowed to perform using the - connection protocol. Some issues are related to security; for - example, the policy SHOULD NOT allow the server to start sessions - or run commands on the client machine, and MUST NOT allow - connections to the authentication agent unless forwarding such - connections has been requested. Other issues, such as which TCP/ - IP ports can be forwarded and by whom, are clearly issues of local - policy. Many of these issues may involve traversing or bypassing - firewalls, and are interrelated with the local security policy. - -4.4 Security Properties - - The primary goal of the SSH protocol is improved security on the - Internet. It attempts to do this in a way that is easy to deploy, - even at the cost of absolute security. - o All encryption, integrity, and public key algorithms used are - well-known, well-established algorithms. - o All algorithms are used with cryptographically sound key sizes - that are believed to provide protection against even the strongest - cryptanalytic attacks for decades. - o All algorithms are negotiated, and in case some algorithm is - broken, it is easy to switch to some other algorithm without - modifying the base protocol. - - Specific concessions were made to make wide-spread fast deployment - easier. The particular case where this comes up is verifying that - the server host key really belongs to the desired host; the protocol - allows the verification to be left out (but this is NOT RECOMMENDED). - This is believed to significantly improve usability in the short - term, until widespread Internet public key infrastructures emerge. - -4.5 Packet Size and Overhead - - Some readers will worry about the increase in packet size due to new - - - -Ylonen & Moffat Expires March 31, 2004 [Page 6] - -Internet-Draft SSH Protocol Architecture Oct 2003 - - - headers, padding, and MAC. The minimum packet size is in the order - of 28 bytes (depending on negotiated algorithms). The increase is - negligible for large packets, but very significant for one-byte - packets (telnet-type sessions). There are, however, several factors - that make this a non-issue in almost all cases: - o The minimum size of a TCP/IP header is 32 bytes. Thus, the - increase is actually from 33 to 51 bytes (roughly). - o The minimum size of the data field of an Ethernet packet is 46 - bytes [RFC-894]. Thus, the increase is no more than 5 bytes. When - Ethernet headers are considered, the increase is less than 10 - percent. - o The total fraction of telnet-type data in the Internet is - negligible, even with increased packet sizes. - - The only environment where the packet size increase is likely to have - a significant effect is PPP [RFC-1134] over slow modem lines (PPP - compresses the TCP/IP headers, emphasizing the increase in packet - size). However, with modern modems, the time needed to transfer is in - the order of 2 milliseconds, which is a lot faster than people can - type. - - There are also issues related to the maximum packet size. To - minimize delays in screen updates, one does not want excessively - large packets for interactive sessions. The maximum packet size is - negotiated separately for each channel. - -4.6 Localization and Character Set Support - - For the most part, the SSH protocols do not directly pass text that - would be displayed to the user. However, there are some places where - such data might be passed. When applicable, the character set for the - data MUST be explicitly specified. In most places, ISO 10646 with - UTF-8 encoding is used [RFC-2279]. When applicable, a field is also - provided for a language tag [RFC-3066]. - - One big issue is the character set of the interactive session. There - is no clear solution, as different applications may display data in - different formats. Different types of terminal emulation may also be - employed in the client, and the character set to be used is - effectively determined by the terminal emulation. Thus, no place is - provided for directly specifying the character set or encoding for - terminal session data. However, the terminal emulation type (e.g. - "vt100") is transmitted to the remote site, and it implicitly - specifies the character set and encoding. Applications typically use - the terminal type to determine what character set they use, or the - character set is determined using some external means. The terminal - emulation may also allow configuring the default character set. In - any case, the character set for the terminal session is considered - - - -Ylonen & Moffat Expires March 31, 2004 [Page 7] - -Internet-Draft SSH Protocol Architecture Oct 2003 - - - primarily a client local issue. - - Internal names used to identify algorithms or protocols are normally - never displayed to users, and must be in US-ASCII. - - The client and server user names are inherently constrained by what - the server is prepared to accept. They might, however, occasionally - be displayed in logs, reports, etc. They MUST be encoded using ISO - 10646 UTF-8, but other encodings may be required in some cases. It - is up to the server to decide how to map user names to accepted user - names. Straight bit-wise binary comparison is RECOMMENDED. - - For localization purposes, the protocol attempts to minimize the - number of textual messages transmitted. When present, such messages - typically relate to errors, debugging information, or some externally - configured data. For data that is normally displayed, it SHOULD be - possible to fetch a localized message instead of the transmitted - message by using a numerical code. The remaining messages SHOULD be - configurable. - -5. Data Type Representations Used in the SSH Protocols - byte - - A byte represents an arbitrary 8-bit value (octet) [RFC-1700]. - Fixed length data is sometimes represented as an array of bytes, - written byte[n], where n is the number of bytes in the array. - - boolean - - A boolean value is stored as a single byte. The value 0 - represents FALSE, and the value 1 represents TRUE. All non-zero - values MUST be interpreted as TRUE; however, applications MUST NOT - store values other than 0 and 1. - - uint32 - - Represents a 32-bit unsigned integer. Stored as four bytes in the - order of decreasing significance (network byte order). For - example, the value 699921578 (0x29b7f4aa) is stored as 29 b7 f4 - aa. - - uint64 - - Represents a 64-bit unsigned integer. Stored as eight bytes in - the order of decreasing significance (network byte order). - - - - - - -Ylonen & Moffat Expires March 31, 2004 [Page 8] - -Internet-Draft SSH Protocol Architecture Oct 2003 - - - string - - Arbitrary length binary string. Strings are allowed to contain - arbitrary binary data, including null characters and 8-bit - characters. They are stored as a uint32 containing its length - (number of bytes that follow) and zero (= empty string) or more - bytes that are the value of the string. Terminating null - characters are not used. - - Strings are also used to store text.

Algorithm Naming - - The SSH protocols refer to particular hash, encryption, integrity, - compression, and key exchange algorithms or protocols by names. - There are some standard algorithms that all implementations MUST - support.

Message Numbers - - SSH packets have message numbers in the range 1 to 255.

Security Considerations - - In order to make the entire body of Security Considerations more - accessible, Security Considerations for the transport, - authentication, and connection documents have been gathered here. - - The transport protocol [1] provides a confidential channel over an - insecure network. It performs server host authentication, key - exchange, encryption, and integrity protection. It also derives a - unique session id that may be used by higher-level protocols. - - The authentication protocol [2] provides a suite of mechanisms which - can be used to authenticate the client user to the server. - Individual mechanisms specified in the in authentication protocol use - the session id provided by the transport protocol and/or depend on - the security and integrity guarantees of the transport protocol. - - The connection protocol [3] specifies a mechanism to multiplex - multiple streams [channels] of data over the confidential and - authenticated transport. It also specifies channels for accessing an - interactive shell, for 'proxy-forwarding' various external protocols - over the secure transport (including arbitrary TCP/IP protocols), and - for accessing secure 'subsystems' on the server host. - -9.1 Pseudo-Random Number Generation - - This protocol binds each session key to the session by including - random, session specific data in the hash used to produce session - keys. Special care should be taken to ensure that all of the random - numbers are of good quality. If the random data here (e.g., DH - - - -Ylonen & Moffat Expires March 31, 2004 [Page 12] - -Internet-Draft SSH Protocol Architecture Oct 2003 - - - parameters) are pseudo-random then the pseudo-random number generator - should be cryptographically secure (i.e., its next output not easily - guessed even when knowing all previous outputs) and, furthermore, - proper entropy needs to be added to the pseudo-random number - generator. RFC 1750 [1750] offers suggestions for sources of random - numbers and entropy. Implementors should note the importance of - entropy and the well-meant, anecdotal warning about the difficulty in - properly implementing pseudo-random number generating functions. - - The amount of entropy available to a given client or server may - sometimes be less than what is required. In this case one must - either resort to pseudo-random number generation regardless of - insufficient entropy or refuse to run the protocol. The latter is - preferable. - -9.2 Transport - -9.2.1 Confidentiality - - It is beyond the scope of this document and the Secure Shell Working - Group to analyze or recommend specific ciphers other than the ones - which have been established and accepted within the industry. At the - time of this writing, ciphers commonly in use include 3DES, ARCFOUR, - twofish, serpent and blowfish. AES has been accepted by The - published as a US Federal Information Processing Standards [FIPS-197] - and the cryptographic community as being acceptable for this purpose - as well has accepted AES. As always, implementors and users should - check current literature to ensure that no recent vulnerabilities - have been found in ciphers used within products. Implementors should - also check to see which ciphers are considered to be relatively - stronger than others and should recommend their use to users over - relatively weaker ciphers. It would be considered good form for an - implementation to politely and unobtrusively notify a user that a - stronger cipher is available and should be used when a weaker one is - actively chosen. - - The "none" cipher is provided for debugging and SHOULD NOT be used - except for that purpose. It's cryptographic properties are - sufficiently described in RFC 2410, which will show that its use does - not meet the intent of this protocol. - - The relative merits of these and other ciphers may also be found in - current literature. Two references that may provide information on - the subject are [SCHNEIER] and [KAUFMAN,PERLMAN,SPECINER]. Both of - these describe the CBC mode of operation of certain ciphers and the - weakness of this scheme. Essentially, this mode is theoretically - vulnerable to chosen cipher-text attacks because of the high - predictability of the start of packet sequence. However, this attack - - - -Ylonen & Moffat Expires March 31, 2004 [Page 13] - -Internet-Draft SSH Protocol Architecture Oct 2003 - - - is still deemed difficult and not considered fully practicable - especially if relatively longer block sizes are used. - - Additionally, another CBC mode attack may be mitigated through the - insertion of packets containing SSH_MSG_IGNORE. Without this - technique, a specific attack may be successful. For this attack - (commonly known as the Rogaway attack - [ROGAWAY],[DAI],[BELLARE,KOHNO,NAMPREMPRE]) to work, the attacker - would need to know the IV of the next block that is going to be - encrypted. In CBC mode that is the output of the encryption of the - previous block. If the attacker does not have any way to see the - packet yet (i.e it is in the internal buffers of the ssh - implementation or even in the kernel) then this attack will not work. - If the last packet has been sent out to the network (i.e the attacker - has access to it) then he can use the attack. - - In the optimal case an implementor would need to add an extra packet - only if the packet has been sent out onto the network and there are - no other packets waiting for transmission. Implementors may wish to - check to see if there are any unsent packets awaiting transmission, - but unfortunately it is not normally easy to obtain this information - from the kernel or buffers. If there are not, then a packet - containing SSH_MSG_IGNORE SHOULD be sent. If a new packet is added - to the stream every time the attacker knows the IV that is supposed - to be used for the next packet, then the attacker will not be able to - guess the correct IV, thus the attack will never be successfull. - - As an example, consider the following case: - - - Client Server - ------ ------ - TCP(seq=x, len=500) -> - contains Record 1 - - [500 ms passes, no ACK] - - TCP(seq=x, len=1000) -> - contains Records 1,2 - - ACK - - - 1. The Nagle algorithm + TCP retransmits mean that the two records - get coalesced into a single TCP segment - 2. Record 2 is *not* at the beginning of the TCP segment and never - will be, since it gets ACKed. - - - - -Ylonen & Moffat Expires March 31, 2004 [Page 14] - -Internet-Draft SSH Protocol Architecture Oct 2003 - - - 3. Yet, the attack is possible because Record 1 has already been - seen. - - As this example indicates, it's totally unsafe to use the existence - of unflushed data in the TCP buffers proper as a guide to whether you - need an empty packet, since when you do the second write(), the - buffers will contain the un-ACKed Record 1. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -Ylonen & Moffat Expires March 31, 2004 [Page 15] - -Internet-Draft SSH Protocol Architecture Oct 2003 - - - On the other hand, it's perfectly safe to have the following - situation: - - - Client Server - ------ ------ - TCP(seq=x, len=500) -> - contains SSH_MSG_IGNORE - - TCP(seq=y, len=500) -> - contains Data - - Provided that the IV for second SSH Record is fixed after the data for - the Data packet is determined -i.e. you do: - read from user - encrypt null packet - encrypt data packet - - -9.2.2 Data Integrity - - This protocol does allow the Data Integrity mechanism to be disabled. - Implementors SHOULD be wary of exposing this feature for any purpose - other than debugging. Users and administrators SHOULD be explicitly - warned anytime the "none" MAC is enabled. - - So long as the "none" MAC is not used, this protocol provides data - integrity. - - Because MACs use a 32 bit sequence number, they might start to leak - information after 2**32 packets have been sent. However, following - the rekeying recommendations should prevent this attack. The - transport protocol [1] recommends rekeying after one gigabyte of - data, and the smallest possible packet is 16 bytes. Therefore, - rekeying SHOULD happen after 2**28 packets at the very most. - -9.2.3 Replay - - The use of a MAC other than 'none' provides integrity and - authentication. In addition, the transport protocol provides a - unique session identifier (bound in part to pseudo-random data that - is part of the algorithm and key exchange process) that can be used - by higher level protocols to bind data to a given session and prevent - replay of data from prior sessions. For example, the authentication - protocol uses this to prevent replay of signatures from previous - sessions. Because public key authentication exchanges are - cryptographically bound to the session (i.e., to the initial key - exchange) they cannot be successfully replayed in other sessions. - - - -Ylonen & Moffat Expires March 31, 2004 [Page 16] - -Internet-Draft SSH Protocol Architecture Oct 2003 - - - Note that the session ID can be made public without harming the - security of the protocol. - - If two session happen to have the same session ID [hash of key - exchanges] then packets from one can be replayed against the other. - It must be stressed that the chances of such an occurrence are, - needless to say, minimal when using modern cryptographic methods. - This is all the more so true when specifying larger hash function - outputs and DH parameters. - - Replay detection using monotonically increasing sequence numbers as - input to the MAC, or HMAC in some cases, is described in [RFC2085] /> - [RFC2246], [RFC2743], [RFC1964], [RFC2025], and [RFC1510]. The - underlying construct is discussed in [RFC2104]. Essentially a - different sequence number in each packet ensures that at least this - one input to the MAC function will be unique and will provide a - nonrecurring MAC output that is not predictable to an attacker. If - the session stays active long enough, however, this sequence number - will wrap. This event may provide an attacker an opportunity to - replay a previously recorded packet with an identical sequence number - but only if the peers have not rekeyed since the transmission of the - first packet with that sequence number. If the peers have rekeyed, - then the replay will be detected as the MAC check will fail. For - this reason, it must be emphasized that peers MUST rekey before a - wrap of the sequence numbers. Naturally, if an attacker does attempt - to replay a captured packet before the peers have rekeyed, then the - receiver of the duplicate packet will not be able to validate the MAC - and it will be discarded. The reason that the MAC will fail is - because the receiver will formulate a MAC based upon the packet - contents, the shared secret, and the expected sequence number. Since - the replayed packet will not be using that expected sequence number - (the sequence number of the replayed packet will have already been - passed by the receiver) then the calculated MAC will not match the - MAC received with the packet. - -9.2.4 Man-in-the-middle - - This protocol makes no assumptions nor provisions for an - infrastructure or means for distributing the public keys of hosts. It - is expected that this protocol will sometimes be used without first - verifying the association between the server host key and the server - host name. Such usage is vulnerable to man-in-the-middle attacks. - This section describes this and encourages administrators and users - to understand the importance of verifying this association before any - session is initiated. - - There are three cases of man-in-the-middle attacks to consider. The - first is where an attacker places a device between the client and the - - - -Ylonen & Moffat Expires March 31, 2004 [Page 17] - -Internet-Draft SSH Protocol Architecture Oct 2003 - - - server before the session is initiated. In this case, the attack - device is trying to mimic the legitimate server and will offer its - public key to the client when the client initiates a session. If it - were to offer the public key of the server, then it would not be able - to decrypt or sign the transmissions between the legitimate server - and the client unless it also had access to the private-key of the - host. The attack device will also, simultaneously to this, initiate - a session to the legitimate server masquerading itself as the client. - If the public key of the server had been securely distributed to the - client prior to that session initiation, the key offered to the - client by the attack device will not match the key stored on the - client. In that case, the user SHOULD be given a warning that the - offered host key does not match the host key cached on the client. - As described in Section 3.1 of [ARCH], the user may be free to accept - the new key and continue the session. It is RECOMMENDED that the - warning provide sufficient information to the user of the client - device so they may make an informed decision. If the user chooses to - continue the session with the stored public-key of the server (not - the public-key offered at the start of the session), then the session - specific data between the attacker and server will be different - between the client-to-attacker session and the attacker-to-server - sessions due to the randomness discussed above. From this, the - attacker will not be able to make this attack work since the attacker - will not be able to correctly sign packets containing this session - specific data from the server since he does not have the private key - of that server. - - The second case that should be considered is similar to the first - case in that it also happens at the time of connection but this case - points out the need for the secure distribution of server public - keys. If the server public keys are not securely distributed then - the client cannot know if it is talking to the intended server. An - attacker may use social engineering techniques to pass off server - keys to unsuspecting users and may then place a man-in-the-middle - attack device between the legitimate server and the clients. If this - is allowed to happen then the clients will form client-to-attacker - sessions and the attacker will form attacker-to-server sessions and - will be able to monitor and manipulate all of the traffic between the - clients and the legitimate servers. Server administrators are - encouraged to make host key fingerprints available for checking by - some means whose security does not rely on the integrity of the - actual host keys. Possible mechanisms are discussed in Section 3.1 - of [SSH-ARCH] and may also include secured Web pages, physical pieces - of paper, etc. Implementors SHOULD provide recommendations on how - best to do this with their implementation. Because the protocol is - extensible, future extensions to the protocol may provide better - mechanisms for dealing with the need to know the server's host key - before connecting. For example, making the host key fingerprint - - - -Ylonen & Moffat Expires March 31, 2004 [Page 18] - -Internet-Draft SSH Protocol Architecture Oct 2003 - - - available through a secure DNS lookup, or using kerberos over gssapi - during key exchange to authenticate the server are possibilities. - - In the third man-in-the-middle case, attackers may attempt to - manipulate packets in transit between peers after the session has - been established. As described in the Replay part of this section, a - successful attack of this nature is very improbable. As in the - Replay section, this reasoning does assume that the MAC is secure and - that it is infeasible to construct inputs to a MAC algorithm to give - a known output. This is discussed in much greater detail in Section - 6 of RFC 2104. If the MAC algorithm has a vulnerability or is weak - enough, then the attacker may be able to specify certain inputs to - yield a known MAC. With that they may be able to alter the contents - of a packet in transit. Alternatively the attacker may be able to - exploit the algorithm vulnerability or weakness to find the shared - secret by reviewing the MACs from captured packets. In either of - those cases, an attacker could construct a packet or packets that - could be inserted into an SSH stream. To prevent that, implementors - are encouraged to utilize commonly accepted MAC algorithms and - administrators are encouraged to watch current literature and - discussions of cryptography to ensure that they are not using a MAC - algorithm that has a recently found vulnerability or weakness. - - In summary, the use of this protocol without a reliable association - of the binding between a host and its host keys is inherently - insecure and is NOT RECOMMENDED. It may however be necessary in - non-security critical environments, and will still provide protection - against passive attacks. Implementors of protocols and applications - running on top of this protocol should keep this possibility in mind. - -9.2.5 Denial-of-service - - This protocol is designed to be used over a reliable transport. If - transmission errors or message manipulation occur, the connection is - closed. The connection SHOULD be re-established if this occurs. - Denial of service attacks of this type ("wire cutter") are almost - impossible to avoid. - - In addition, this protocol is vulnerable to Denial of Service attacks - because an attacker can force the server to go through the CPU and - memory intensive tasks of connection setup and key exchange without - authenticating. Implementors SHOULD provide features that make this - more difficult. For example, only allowing connections from a subset - of IPs known to have valid users. - -9.2.6 Covert Channels - - The protocol was not designed to eliminate covert channels. For - - - -Ylonen & Moffat Expires March 31, 2004 [Page 19] - -Internet-Draft SSH Protocol Architecture Oct 2003 - - - example, the padding, SSH_MSG_IGNORE messages, and several other - places in the protocol can be used to pass covert information, and - the recipient has no reliable way to verify whether such information - is being sent. - -9.2.7 Forward Secrecy - - It should be noted that the Diffie-Hellman key exchanges may provide - perfect forward secrecy (PFS). PFS is essentially defined as the - cryptographic property of a key-establishment protocol in which the - compromise of a session key or long-term private key after a given - session does not cause the compromise of any earlier session. [ANSI - T1.523-2001] SSHv2 sessions resulting from a key exchange using - diffie-hellman-group1-sha1 are secure even if private keying/ - authentication material is later revealed, but not if the session - keys are revealed. So, given this definition of PFS, SSHv2 does have - PFS. It is hoped that all other key exchange mechanisms proposed and - used in the future will also provide PFS. This property is not - commuted to any of the applications or protocols using SSH as a - transport however. The transport layer of SSH provides - confidentiality for password authentication and other methods that - rely on secret data. - - Of course, if the DH private parameters for the client and server are - revealed then the session key is revealed, but these items can be - thrown away after the key exchange completes. It's worth pointing - out that these items should not be allowed to end up on swap space - and that they should be erased from memory as soon as the key - exchange completes. - -9.3 Authentication Protocol - - The purpose of this protocol is to perform client user - authentication. It assumes that this run over a secure transport - layer protocol, which has already authenticated the server machine, - established an encrypted communications channel, and computed a - unique session identifier for this session. - - Several authentication methods with different security - characteristics are allowed. It is up to the server's local policy - to decide which methods (or combinations of methods) it is willing to - accept for each user. Authentication is no stronger than the weakest - combination allowed. - - The server may go into a "sleep" period after repeated unsuccessful - authentication attempts to make key search more difficult for - attackers. Care should be taken so that this doesn't become a - self-denial of service vector. - - - -Ylonen & Moffat Expires March 31, 2004 [Page 20] - -Internet-Draft SSH Protocol Architecture Oct 2003 - - -9.3.1 Weak Transport - - If the transport layer does not provide confidentiality, - authentication methods that rely on secret data SHOULD be disabled. - If it does not provide strong integrity protection, requests to - change authentication data (e.g. a password change) SHOULD be - disabled to prevent an attacker from modifying the ciphertext - without being noticed, or rendering the new authentication data - unusable (denial of service). - - The assumption as stated above that the Authentication Protocol only - run over a secure transport that has previously authenticated the - server is very important to note. People deploying SSH are reminded - of the consequences of man-in-the-middle attacks if the client does - not have a very strong a priori association of the server with the - host key of that server. Specifically for the case of the - Authentication Protocol the client may form a session to a - man-in-the-middle attack device and divulge user credentials such as - their username and password. Even in the cases of authentication - where no user credentials are divulged, an attacker may still gain - information they shouldn't have by capturing key-strokes in much the - same way that a honeypot works. - -9.3.2 Debug messages - - Special care should be taken when designing debug messages. These - messages may reveal surprising amounts of information about the host - if not properly designed. Debug messages can be disabled (during - user authentication phase) if high security is required. - Administrators of host machines should make all attempts to - compartmentalize all event notification messages and protect them - from unwarranted observation. Developers should be aware of the - sensitive nature of some of the normal event messages and debug - messages and may want to provide guidance to administrators on ways - to keep this information away from unauthorized people. Developers - should consider minimizing the amount of sensitive information - obtainable by users during the authentication phase in accordance - with the local policies. For this reason, it is RECOMMENDED that - debug messages be initially disabled at the time of deployment and - require an active decision by an administrator to allow them to be - enabled. It is also RECOMMENDED that a message expressing this - concern be presented to the administrator of a system when the action - is taken to enable debugging messages. - -9.3.3 Local security policy - - Implementer MUST ensure that the credentials provided validate the - professed user and also MUST ensure that the local policy of the - - - -Ylonen & Moffat Expires March 31, 2004 [Page 21] - -Internet-Draft SSH Protocol Architecture Oct 2003 - - - server permits the user the access requested. In particular, because - of the flexible nature of the SSH connection protocol, it may not be - possible to determine the local security policy, if any, that should - apply at the time of authentication because the kind of service being - requested is not clear at that instant. For example, local policy - might allow a user to access files on the server, but not start an - interactive shell. However, during the authentication protocol, it is - not known whether the user will be accessing files or attempting to - use an interactive shell, or even both. In any event, where local - security policy for the server host exists, it MUST be applied and - enforced correctly. - - Implementors are encouraged to provide a default local policy and - make its parameters known to administrators and users. At the - discretion of the implementors, this default policy may be along the - lines of 'anything goes' where there are no restrictions placed upon - users, or it may be along the lines of 'excessively restrictive' in - which case the administrators will have to actively make changes to - this policy to meet their needs. Alternatively, it may be some - attempt at providing something practical and immediately useful to - the administrators of the system so they don't have to put in much - effort to get SSH working. Whatever choice is made MUST be applied - and enforced as required above. - -9.3.4 Public key authentication - - The use of public-key authentication assumes that the client host has - not been compromised. It also assumes that the private-key of the - server host has not been compromised. - - This risk can be mitigated by the use of passphrases on private keys; - however, this is not an enforceable policy. The use of smartcards, - or other technology to make passphrases an enforceable policy is - suggested. - - The server could require both password and public-key authentication, - however, this requires the client to expose its password to the - server (see section on password authentication below.) - -9.3.5 Password authentication - - The password mechanism as specified in the authentication protocol - assumes that the server has not been compromised. If the server has - been compromised, using password authentication will reveal a valid - username / password combination to the attacker, which may lead to - further compromises. - - This vulnerability can be mitigated by using an alternative form of - - - -Ylonen & Moffat Expires March 31, 2004 [Page 22] - -Internet-Draft SSH Protocol Architecture Oct 2003 - - - authentication. For example, public-key authentication makes no - assumptions about security on the server. - -9.3.6 Host based authentication - - Host based authentication assumes that the client has not been - compromised. There are no mitigating strategies, other than to use - host based authentication in combination with another authentication - method. - -9.4 Connection protocol - -9.4.1 End point security - - End point security is assumed by the connection protocol. If the - server has been compromised, any terminal sessions, port forwarding, - or systems accessed on the host are compromised. There are no - mitigating factors for this. - - If the client end point has been compromised, and the server fails to - stop the attacker at the authentication protocol, all services - exposed (either as subsystems or through forwarding) will be - vulnerable to attack. Implementors SHOULD provide mechanisms for - administrators to control which services are exposed to limit the - vulnerability of other services. - - These controls might include controlling which machines and ports can - be target in 'port-forwarding' operations, which users are allowed to - use interactive shell facilities, or which users are allowed to use - exposed subsystems. - -9.4.2 Proxy forwarding - - The SSH connection protocol allows for proxy forwarding of other - protocols such as SNMP, POP3, and HTTP. This may be a concern for - network administrators who wish to control the access of certain - applications by users located outside of their physical location. - Essentially, the forwarding of these protocols may violate site - specific security policies as they may be undetectably tunneled - through a firewall. Implementors SHOULD provide an administrative - mechanism to control the proxy forwarding functionality so that site - specific security policies may be upheld. - - In addition, a reverse proxy forwarding functionality is available, - which again can be used to bypass firewall controls. - - As indicated above, end-point security is assumed during proxy - forwarding operations. Failure of end-point security will compromise - - - -Ylonen & Moffat Expires March 31, 2004 [Page 23] - -Internet-Draft SSH Protocol Architecture Oct 2003 - - - all data passed over proxy forwarding. - -9.4.3 X11 forwarding - - Another form of proxy forwarding provided by the ssh connection - protocol is the forwarding of the X11 protocol. If end-point - security has been compromised, X11 forwarding may allow attacks - against the X11 server. Users and administrators should, as a matter - of course, use appropriate X11 security mechanisms to prevent - unauthorized use of the X11 server. Implementors, administrators and - users who wish to further explore the security mechanisms of X11 are - invited to read [SCHEIFLER] and analyze previously reported problems - with the interactions between SSH forwarding and X11 in CERT - vulnerabilities VU#363181 and VU#118892 [CERT]. - - X11 display forwarding with SSH, by itself, is not sufficient to - correct well known problems with X11 security [VENEMA]. However, X11 - display forwarding in SSHv2 (or other, secure protocols), combined - with actual and pseudo-displays which accept connections only over - local IPC mechanisms authorized by permissions or ACLs, does correct - many X11 security problems as long as the "none" MAC is not used. It - is RECOMMENDED that X11 display implementations default to allowing - display opens only over local IPC. It is RECOMMENDED that SSHv2 - server implementations that support X11 forwarding default to - allowing display opens only over local IPC. On single-user systems - it might be reasonable to default to allowing local display opens - over TCP/IP. - - Implementors of the X11 forwarding protocol SHOULD implement the - magic cookie access checking spoofing mechanism as described in - [ssh-connect] as an additional mechanism to prevent unauthorized use - of the proxy. - -Normative References - - [SSH-ARCH] - Ylonen, T., "SSH Protocol Architecture", I-D - draft-ietf-architecture-15.txt, Oct 2003. - - [SSH-TRANS] - Ylonen, T., "SSH Transport Layer Protocol", I-D - draft-ietf-transport-17.txt, Oct 2003. - - [SSH-USERAUTH] - Ylonen, T., "SSH Authentication Protocol", I-D - draft-ietf-userauth-18.txt, Oct 2003. - - [SSH-CONNECT] - - - -Ylonen & Moffat Expires March 31, 2004 [Page 24] - -Internet-Draft SSH Protocol Architecture Oct 2003 - - - Ylonen, T., "SSH Connection Protocol", I-D - draft-ietf-connect-18.txt, Oct 2003. - - [SSH-NUMBERS] - Lehtinen, S. and D.

Conventions Used in This Document - - The keywords "MUST", "MUST NOT", "REQUIRED", "SHOULD", "SHOULD NOT", - and "MAY" that appear in this document are to be interpreted as - described in [RFC2119]. - - The used data types and terminology are specified in the architecture - document [SSH-ARCH]. - - The architecture document also discusses the algorithm naming - conventions that MUST be used with the SSH protocols. - -4. Global Requests - - There are several kinds of requests that affect the state of the - remote end "globally", independent of any channels. An example is a - request to start TCP/IP forwarding for a specific port. All such - requests use the following format. - - byte SSH_MSG_GLOBAL_REQUEST - string request name (restricted to US-ASCII) - boolean want reply - ... request-specific data follows - - - - -Ylonen & Moffat, Editor Expires March 31, 2004 [Page 3] - -Internet-Draft SSH Connection Protocol Oct 2003 - - - Request names follow the DNS extensibility naming convention outlined - in [SSH-ARCH]. - - The recipient will respond to this message with - SSH_MSG_REQUEST_SUCCESS or SSH_MSG_REQUEST_FAILURE if `want reply' is - TRUE. - - byte SSH_MSG_REQUEST_SUCCESS - ..... response specific data - - Usually the response specific data is non-existent. - - If the recipient does not recognize or support the request, it simply - responds with SSH_MSG_REQUEST_FAILURE. - - byte SSH_MSG_REQUEST_FAILURE - - -5. Channel Mechanism - - All terminal sessions, forwarded connections, etc. are channels. - Either side may open a channel. Multiple channels are multiplexed - into a single connection. - - Channels are identified by numbers at each end. The number referring - to a channel may be different on each side. Requests to open a - channel contain the sender's channel number. Any other - channel-related messages contain the recipient's channel number for - the channel. - - Channels are flow-controlled. No data may be sent to a channel until - a message is received to indicate that window space is available. - -5.1 Opening a Channel - - When either side wishes to open a new channel, it allocates a local - number for the channel. It then sends the following message to the - other side, and includes the local channel number and initial window - size in the message. - - byte SSH_MSG_CHANNEL_OPEN - string channel type (restricted to US-ASCII) - uint32 sender channel - uint32 initial window size - uint32 maximum packet size - ... channel type specific data follows - - The channel type is a name as described in the SSH architecture - - - -Ylonen & Moffat, Editor Expires March 31, 2004 [Page 4] - -Internet-Draft SSH Connection Protocol Oct 2003 - - - document, with similar extension mechanisms. `sender channel' is a - local identifier for the channel used by the sender of this message. - `initial window size' specifies how many bytes of channel data can be - sent to the sender of this message without adjusting the window. - `Maximum packet size' specifies the maximum size of an individual - data packet that can be sent to the sender (for example, one might - want to use smaller packets for interactive connections to get better - interactive response on slow links). - - The remote side then decides whether it can open the channel, and - responds with either - - byte SSH_MSG_CHANNEL_OPEN_CONFIRMATION - uint32 recipient channel - uint32 sender channel - uint32 initial window size - uint32 maximum packet size - ... channel type specific data follows - - where `recipient channel' is the channel number given in the original - open request, and `sender channel' is the channel number allocated by - the other side, or - - byte SSH_MSG_CHANNEL_OPEN_FAILURE - uint32 recipient channel - uint32 reason code - string additional textual information (ISO-10646 UTF-8 [RFC2279]) - string language tag (as defined in [RFC3066]) - - If the recipient of the SSH_MSG_CHANNEL_OPEN message does not support - the specified channel type, it simply responds with - SSH_MSG_CHANNEL_OPEN_FAILURE. The client MAY show the additional - information to the user. If this is done, the client software should - take the precautions discussed in [SSH-ARCH]. - - The following reason codes are defined: - - #define SSH_OPEN_ADMINISTRATIVELY_PROHIBITED 1 - #define SSH_OPEN_CONNECT_FAILED 2 - #define SSH_OPEN_UNKNOWN_CHANNEL_TYPE 3 - #define SSH_OPEN_RESOURCE_SHORTAGE 4 - - -5.2 Data Transfer - - The window size specifies how many bytes the other party can send - before it must wait for the window to be adjusted. Both parties use - the following message to adjust the window. - - - -Ylonen & Moffat, Editor Expires March 31, 2004 [Page 5] - -Internet-Draft SSH Connection Protocol Oct 2003 - - - byte SSH_MSG_CHANNEL_WINDOW_ADJUST - uint32 recipient channel - uint32 bytes to add - - After receiving this message, the recipient MAY send the given number - of bytes more than it was previously allowed to send; the window size - is incremented. - - Data transfer is done with messages of the following type. - - byte SSH_MSG_CHANNEL_DATA - uint32 recipient channel - string data - - The maximum amount of data allowed is the current window size. The - window size is decremented by the amount of data sent. Both parties - MAY ignore all extra data sent after the allowed window is empty. - - Additionally, some channels can transfer several types of data. An - example of this is stderr data from interactive sessions. Such data - can be passed with SSH_MSG_CHANNEL_EXTENDED_DATA messages, where a - separate integer specifies the type of the data. The available types - and their interpretation depend on the type of the channel. - - byte SSH_MSG_CHANNEL_EXTENDED_DATA - uint32 recipient_channel - uint32 data_type_code - string data - - Data sent with these messages consumes the same window as ordinary - data. - - Currently, only the following type is defined. - - #define SSH_EXTENDED_DATA_STDERR 1 - - -5.3 Closing a Channel - - When a party will no longer send more data to a channel, it SHOULD - send SSH_MSG_CHANNEL_EOF. - - byte SSH_MSG_CHANNEL_EOF - uint32 recipient_channel - - No explicit response is sent to this message; however, the - application may send EOF to whatever is at the other end of the - channel. Note that the channel remains open after this message, and - - - -Ylonen & Moffat, Editor Expires March 31, 2004 [Page 6] - -Internet-Draft SSH Connection Protocol Oct 2003 - - - more data may still be sent in the other direction. This message - does not consume window space and can be sent even if no window space - is available. - - When either party wishes to terminate the channel, it sends - SSH_MSG_CHANNEL_CLOSE. Upon receiving this message, a party MUST - send back a SSH_MSG_CHANNEL_CLOSE unless it has already sent this - message for the channel. The channel is considered closed for a - party when it has both sent and received SSH_MSG_CHANNEL_CLOSE, and - the party may then reuse the channel number. A party MAY send - SSH_MSG_CHANNEL_CLOSE without having sent or received - SSH_MSG_CHANNEL_EOF. - - byte SSH_MSG_CHANNEL_CLOSE - uint32 recipient_channel - - This message does not consume window space and can be sent even if no - window space is available. - - It is recommended that any data sent before this message is delivered - to the actual destination, if possible. - -5.4 Channel-Specific Requests - - Many channel types have extensions that are specific to that - particular channel type. An example is requesting a pty (pseudo - terminal) for an interactive session. - - All channel-specific requests use the following format. - - byte SSH_MSG_CHANNEL_REQUEST - uint32 recipient channel - string request type (restricted to US-ASCII) - boolean want reply - ... type-specific data - - If want reply is FALSE, no response will be sent to the request. - Otherwise, the recipient responds with either SSH_MSG_CHANNEL_SUCCESS - or SSH_MSG_CHANNEL_FAILURE, or request-specific continuation - messages. If the request is not recognized or is not supported for - the channel, SSH_MSG_CHANNEL_FAILURE is returned. - - This message does not consume window space and can be sent even if no - window space is available. Request types are local to each channel - type. - - The client is allowed to send further messages without waiting for - the response to the request. - - - -Ylonen & Moffat, Editor Expires March 31, 2004 [Page 7] - -Internet-Draft SSH Connection Protocol Oct 2003 - - - request type names follow the DNS extensibility naming convention - outlined in [SSH-ARCH] - - byte SSH_MSG_CHANNEL_SUCCESS - uint32 recipient_channel - - - byte SSH_MSG_CHANNEL_FAILURE - uint32 recipient_channel - - These messages do not consume window space and can be sent even if no - window space is available. - -6. Interactive Sessions - - A session is a remote execution of a program. The program may be a - shell, an application, a system command, or some built-in subsystem. - It may or may not have a tty, and may or may not involve X11 - forwarding. Multiple sessions can be active simultaneously. - -6.1 Opening a Session - - A session is started by sending the following message. - - byte SSH_MSG_CHANNEL_OPEN - string "session" - uint32 sender channel - uint32 initial window size - uint32 maximum packet size - - Client implementations SHOULD reject any session channel open - requests to make it more difficult for a corrupt server to attack the - client. - -6.2 Requesting a Pseudo-Terminal - - A pseudo-terminal can be allocated for the session by sending the - following message. - - byte SSH_MSG_CHANNEL_REQUEST - uint32 recipient_channel - string "pty-req" - boolean want_reply - string TERM environment variable value (e.g., vt100) - uint32 terminal width, characters (e.g., 80) - uint32 terminal height, rows (e.g., 24) - uint32 terminal width, pixels (e.g., 640) - uint32 terminal height, pixels (e.g., 480) - - - -Ylonen & Moffat, Editor Expires March 31, 2004 [Page 8] - -Internet-Draft SSH Connection Protocol Oct 2003 - - - string encoded terminal modes - - The encoding of terminal modes is described in Section Encoding of - Terminal Modes (Section 8). Zero dimension parameters MUST be - ignored. The character/row dimensions override the pixel dimensions - (when nonzero). Pixel dimensions refer to the drawable area of the - window. - - The dimension parameters are only informational. - - The client SHOULD ignore pty requests. - -6.3 X11 Forwarding - -6.3.1 Requesting X11 Forwarding - - X11 forwarding may be requested for a session by sending - - byte SSH_MSG_CHANNEL_REQUEST - uint32 recipient channel - string "x11-req" - boolean want reply - boolean single connection - string x11 authentication protocol - string x11 authentication cookie - uint32 x11 screen number - - It is recommended that the authentication cookie that is sent be a - fake, random cookie, and that the cookie is checked and replaced by - the real cookie when a connection request is received. - - X11 connection forwarding should stop when the session channel is - closed; however, already opened forwardings should not be - automatically closed when the session channel is closed. - - If `single connection' is TRUE, only a single connection should be - forwarded. No more connections will be forwarded after the first, or - after the session channel has been closed. - - The "x11 authentication protocol" is the name of the X11 - authentication method used, e.g. "MIT-MAGIC-COOKIE-1". - - The x11 authentication cookie MUST be hexadecimal encoded. - - X Protocol is documented in [SCHEIFLER]. - - - - - - -Ylonen & Moffat, Editor Expires March 31, 2004 [Page 9] - -Internet-Draft SSH Connection Protocol Oct 2003 - - -6.3.2 X11 Channels - - X11 channels are opened with a channel open request. The resulting - channels are independent of the session, and closing the session - channel does not close the forwarded X11 channels. - - byte SSH_MSG_CHANNEL_OPEN - string "x11" - uint32 sender channel - uint32 initial window size - uint32 maximum packet size - string originator address (e.g. "192.168.7.38") - uint32 originator port - - The recipient should respond with SSH_MSG_CHANNEL_OPEN_CONFIRMATION - or SSH_MSG_CHANNEL_OPEN_FAILURE. - - Implementations MUST reject any X11 channel open requests if they - have not requested X11 forwarding. - -6.4 Environment Variable Passing - - Environment variables may be passed to the shell/command to be - started later. Uncontrolled setting of environment variables in a - privileged process can be a security hazard. It is recommended that - implementations either maintain a list of allowable variable names or - only set environment variables after the server process has dropped - sufficient privileges. - - byte SSH_MSG_CHANNEL_REQUEST - uint32 recipient channel - string "env" - boolean want reply - string variable name - string variable value - - -6.5 Starting a Shell or a Command - - Once the session has been set up, a program is started at the remote - end. The program can be a shell, an application program or a - subsystem with a host-independent name. Only one of these requests - can succeed per channel. - - byte SSH_MSG_CHANNEL_REQUEST - uint32 recipient channel - string "shell" - boolean want reply - - - -Ylonen & Moffat, Editor Expires March 31, 2004 [Page 10] - -Internet-Draft SSH Connection Protocol Oct 2003 - - - This message will request the user's default shell (typically defined - in /etc/passwd in UNIX systems) to be started at the other end. - - byte SSH_MSG_CHANNEL_REQUEST - uint32 recipient channel - string "exec" - boolean want reply - string command - - This message will request the server to start the execution of the - given command. The command string may contain a path. Normal - precautions MUST be taken to prevent the execution of unauthorized - commands. - - byte SSH_MSG_CHANNEL_REQUEST - uint32 recipient channel - string "subsystem" - boolean want reply - string subsystem name - - This last form executes a predefined subsystem. It is expected that - these will include a general file transfer mechanism, and possibly - other features. Implementations may also allow configuring more such - mechanisms. As the user's shell is usually used to execute the - subsystem, it is advisable for the subsystem protocol to have a - "magic cookie" at the beginning of the protocol transaction to - distinguish it from arbitrary output generated by shell - initialization scripts etc. This spurious output from the shell may - be filtered out either at the server or at the client. - - The server SHOULD not halt the execution of the protocol stack when - starting a shell or a program. All input and output from these SHOULD - be redirected to the channel or to the encrypted tunnel. - - It is RECOMMENDED to request and check the reply for these messages. - The client SHOULD ignore these messages. - - Subsystem names follow the DNS extensibility naming convention - outlined in [SSH-ARCH]. - -6.6 Session Data Transfer - - Data transfer for a session is done using SSH_MSG_CHANNEL_DATA and - SSH_MSG_CHANNEL_EXTENDED_DATA packets and the window mechanism. The - extended data type SSH_EXTENDED_DATA_STDERR has been defined for - stderr data. - - - - - -Ylonen & Moffat, Editor Expires March 31, 2004 [Page 11] - -Internet-Draft SSH Connection Protocol Oct 2003 - - -6.7 Window Dimension Change Message - - When the window (terminal) size changes on the client side, it MAY - send a message to the other side to inform it of the new dimensions. - - byte SSH_MSG_CHANNEL_REQUEST - uint32 recipient_channel - string "window-change" - boolean FALSE - uint32 terminal width, columns - uint32 terminal height, rows - uint32 terminal width, pixels - uint32 terminal height, pixels - - No response SHOULD be sent to this message. - -6.8 Local Flow Control - - On many systems, it is possible to determine if a pseudo-terminal is - using control-S/control-Q flow control. When flow control is - allowed, it is often desirable to do the flow control at the client - end to speed up responses to user requests. This is facilitated by - the following notification. Initially, the server is responsible for - flow control. (Here, again, client means the side originating the - session, and server means the other side.) - - The message below is used by the server to inform the client when it - can or cannot perform flow control (control-S/control-Q processing). - If `client can do' is TRUE, the client is allowed to do flow control - using control-S and control-Q. The client MAY ignore this message. - - byte SSH_MSG_CHANNEL_REQUEST - uint32 recipient channel - string "xon-xoff" - boolean FALSE - boolean client can do - - No response is sent to this message. - -6.9 Signals - - A signal can be delivered to the remote process/service using the - following message. Some systems may not implement signals, in which - case they SHOULD ignore this message. - - byte SSH_MSG_CHANNEL_REQUEST - uint32 recipient channel - string "signal" - - - -Ylonen & Moffat, Editor Expires March 31, 2004 [Page 12] - -Internet-Draft SSH Connection Protocol Oct 2003 - - - boolean FALSE - string signal name without the "SIG" prefix. - - Signal names will be encoded as discussed in the "exit-signal" - SSH_MSG_CHANNEL_REQUEST. - -6.10 Returning Exit Status - - When the command running at the other end terminates, the following - message can be sent to return the exit status of the command. - Returning the status is RECOMMENDED. No acknowledgment is sent for - this message. The channel needs to be closed with - SSH_MSG_CHANNEL_CLOSE after this message. - - The client MAY ignore these messages. - - byte SSH_MSG_CHANNEL_REQUEST - uint32 recipient_channel - string "exit-status" - boolean FALSE - uint32 exit_status - - The remote command may also terminate violently due to a signal. - Such a condition can be indicated by the following message. A zero - exit_status usually means that the command terminated successfully. - - byte SSH_MSG_CHANNEL_REQUEST - uint32 recipient channel - string "exit-signal" - boolean FALSE - string signal name without the "SIG" prefix. - boolean core dumped - string error message (ISO-10646 UTF-8) - string language tag (as defined in [RFC3066]) - - The signal name is one of the following (these are from [POSIX]) - - ABRT - ALRM - FPE - HUP - ILL - INT - KILL - PIPE - QUIT - SEGV - TERM - - - -Ylonen & Moffat, Editor Expires March 31, 2004 [Page 13] - -Internet-Draft SSH Connection Protocol Oct 2003 - - - USR1 - USR2 - - Additional signal names MAY be sent in the format "sig-name@xyz", - where `sig-name' and `xyz' may be anything a particular implementor - wants (except the `@' sign). However, it is suggested that if a - `configure' script is used, the non-standard signal names it finds be - encoded as "[email protected]", where `SIG' is the signal name - without the "SIG" prefix, and `xyz' be the host type, as determined - by `config.guess'. - - The `error message' contains an additional explanation of the error - message. The message may consist of multiple lines. The client - software MAY display this message to the user. If this is done, the - client software should take the precautions discussed in [SSH-ARCH]. - -7. TCP/IP Port Forwarding - -7.1 Requesting Port Forwarding - - A party need not explicitly request forwardings from its own end to - the other direction. However, if it wishes that connections to a - port on the other side be forwarded to the local side, it must - explicitly request this. - - - byte SSH_MSG_GLOBAL_REQUEST - string "tcpip-forward" - boolean want reply - string address to bind (e.g. "0.0.0.0") - uint32 port number to bind - - `Address to bind' and `port number to bind' specify the IP address - and port to which the socket to be listened is bound. The address - should be "0.0.0.0" if connections are allowed from anywhere. (Note - that the client can still filter connections based on information - passed in the open request.) - - Implementations should only allow forwarding privileged ports if the - user has been authenticated as a privileged user. - - Client implementations SHOULD reject these messages; they are - normally only sent by the client. - - - If a client passes 0 as port number to bind and has want reply TRUE - then the server allocates the next available unprivileged port number - and replies with the following message, otherwise there is no - - - -Ylonen & Moffat, Editor Expires March 31, 2004 [Page 14] - -Internet-Draft SSH Connection Protocol Oct 2003 - - - response specific data. - - - byte SSH_MSG_GLOBAL_REQUEST_SUCCESS - uint32 port that was bound on the server - - A port forwarding can be cancelled with the following message. Note - that channel open requests may be received until a reply to this - message is received. - - byte SSH_MSG_GLOBAL_REQUEST - string "cancel-tcpip-forward" - boolean want reply - string address_to_bind (e.g. "127.0.0.1") - uint32 port number to bind - - Client implementations SHOULD reject these messages; they are - normally only sent by the client. - -7.2 TCP/IP Forwarding Channels - - When a connection comes to a port for which remote forwarding has - been requested, a channel is opened to forward the port to the other - side. - - byte SSH_MSG_CHANNEL_OPEN - string "forwarded-tcpip" - uint32 sender channel - uint32 initial window size - uint32 maximum packet size - string address that was connected - uint32 port that was connected - string originator IP address - uint32 originator port - - Implementations MUST reject these messages unless they have - previously requested a remote TCP/IP port forwarding with the given - port number. - - When a connection comes to a locally forwarded TCP/IP port, the - following packet is sent to the other side. Note that these messages - MAY be sent also for ports for which no forwarding has been - explicitly requested. The receiving side must decide whether to - allow the forwarding. - - byte SSH_MSG_CHANNEL_OPEN - string "direct-tcpip" - uint32 sender channel - - - -Ylonen & Moffat, Editor Expires March 31, 2004 [Page 15] - -Internet-Draft SSH Connection Protocol Oct 2003 - - - uint32 initial window size - uint32 maximum packet size - string host to connect - uint32 port to connect - string originator IP address - uint32 originator port - - `Host to connect' and `port to connect' specify the TCP/IP host and - port where the recipient should connect the channel. `Host to - connect' may be either a domain name or a numeric IP address. - - `Originator IP address' is the numeric IP address of the machine - where the connection request comes from, and `originator port' is the - port on the originator host from where the connection came from. - - Forwarded TCP/IP channels are independent of any sessions, and - closing a session channel does not in any way imply that forwarded - connections should be closed. - - Client implementations SHOULD reject direct TCP/IP open requests for - security reasons. - -8. Encoding of Terminal Modes - - Terminal modes (as passed in a pty request) are encoded into a byte - stream. It is intended that the coding be portable across different - environments. - - The tty mode description is a stream of bytes. The stream consists - of opcode-argument pairs. It is terminated by opcode TTY_OP_END (0). - Opcodes 1 to 159 have a single uint32 argument. Opcodes 160 to 255 - are not yet defined, and cause parsing to stop (they should only be - used after any other data). - - The client SHOULD put in the stream any modes it knows about, and the - server MAY ignore any modes it does not know about. This allows some - degree of machine-independence, at least between systems that use a - POSIX-like tty interface. The protocol can support other systems as - well, but the client may need to fill reasonable values for a number - of parameters so the server pty gets set to a reasonable mode (the - server leaves all unspecified mode bits in their default values, and - only some combinations make sense). - - The following opcodes have been defined. The naming of opcodes - mostly follows the POSIX terminal mode flags. - - 0 TTY_OP_END Indicates end of options. - 1 VINTR Interrupt character; 255 if none. Similarly for the - - - -Ylonen & Moffat, Editor Expires March 31, 2004 [Page 16] - -Internet-Draft SSH Connection Protocol Oct 2003 - - - other characters. Not all of these characters are - supported on all systems. - 2 VQUIT The quit character (sends SIGQUIT signal on POSIX - systems). - 3 VERASE Erase the character to left of the cursor. - 4 VKILL Kill the current input line. - 5 VEOF End-of-file character (sends EOF from the terminal). - 6 VEOL End-of-line character in addition to carriage return - and/or linefeed. - 7 VEOL2 Additional end-of-line character. - 8 VSTART Continues paused output (normally control-Q). - 9 VSTOP Pauses output (normally control-S). - 10 VSUSP Suspends the current program. - 11 VDSUSP Another suspend character. - 12 VREPRINT Reprints the current input line. - 13 VWERASE Erases a word left of cursor. - 14 VLNEXT Enter the next character typed literally, even if it - is a special character - 15 VFLUSH Character to flush output. - 16 VSWTCH Switch to a different shell layer. - 17 VSTATUS Prints system status line (load, command, pid etc). - 18 VDISCARD Toggles the flushing of terminal output. - 30 IGNPAR The ignore parity flag.

Introduction - - This protocol provides secure file transfer (and more generally file - system access) functionality over a reliable data stream, such as a - channel in the SSH2 protocol [3]. - - This protocol is designed so that it could be used to implement a - secure remote file system service, as well as a secure file transfer - service. - - This protocol assumes that it runs over a secure channel, and that - the server has already authenticated the user at the client end, and - that the identity of the client user is externally available to the - server implementation. - - In general, this protocol follows a simple request-response model. - Each request and response contains a sequence number and multiple - requests may be pending simultaneously. There are a relatively large - number of different request messages, but a small number of possible - response messages. Each request has one or more response messages - that may be returned in result (e.g., a read either returns data or - reports error status). - - The packet format descriptions in this specification follow the - notation presented in the secsh architecture draft.[3]. - - Even though this protocol is described in the context of the SSH2 - protocol, this protocol is general and independent of the rest of the - SSH2 protocol suite. It could be used in a number of different - applications, such as secure file transfer over TLS RFC 2246 [1] and - transfer of management information in VPN applications. - - - - - - - - - - - - - - - - - - - - -Ylonen & Lehtinen Expires April 1, 2002 [Page 3] - -Internet-Draft SSH File Transfer Protocol October 2001 - - -2. Use with the SSH Connection Protocol - - When used with the SSH2 Protocol suite, this protocol is intended to - be used from the SSH Connection Protocol [5] as a subsystem, as - described in section ``Starting a Shell or a Command''. The - subsystem name used with this protocol is "sftp". - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -Ylonen & Lehtinen Expires April 1, 2002 [Page 4] - -Internet-Draft SSH File Transfer Protocol October 2001 - - -3. General Packet Format - - All packets transmitted over the secure connection are of the - following format: - - uint32 length - byte type - byte[length - 1] data payload - - That is, they are just data preceded by 32-bit length and 8-bit type - fields. The `length' is the length of the data area, and does not - include the `length' field itself. The format and interpretation of - the data area depends on the packet type. - - All packet descriptions below only specify the packet type and the - data that goes into the data field. Thus, they should be prefixed by - the `length' and `type' fields. - - The maximum size of a packet is in practice determined by the client - (the maximum size of read or write requests that it sends, plus a few - bytes of packet overhead). All servers SHOULD support packets of at - least 34000 bytes (where the packet size refers to the full length, - including the header above). This should allow for reads and writes - of at most 32768 bytes. - - There is no limit on the number of outstanding (non-acknowledged) - requests that the client may send to the server. In practice this is - limited by the buffering available on the data stream and the queuing - performed by the server. If the server's queues are full, it should - not read any more data from the stream, and flow control will prevent - the client from sending more requests. Note, however, that while - there is no restriction on the protocol level, the client's API may - provide a limit in order to prevent infinite queuing of outgoing - requests at the client. - - - - - - - - - - - - - - - - - -Ylonen & Lehtinen Expires April 1, 2002 [Page 5] - -Internet-Draft SSH File Transfer Protocol October 2001 - - - The following values are defined for packet types. - - #define SSH_FXP_INIT 1 - #define SSH_FXP_VERSION 2 - #define SSH_FXP_OPEN 3 - #define SSH_FXP_CLOSE 4 - #define SSH_FXP_READ 5 - #define SSH_FXP_WRITE 6 - #define SSH_FXP_LSTAT 7 - #define SSH_FXP_FSTAT 8 - #define SSH_FXP_SETSTAT 9 - #define SSH_FXP_FSETSTAT 10 - #define SSH_FXP_OPENDIR 11 - #define SSH_FXP_READDIR 12 - #define SSH_FXP_REMOVE 13 - #define SSH_FXP_MKDIR 14 - #define SSH_FXP_RMDIR 15 - #define SSH_FXP_REALPATH 16 - #define SSH_FXP_STAT 17 - #define SSH_FXP_RENAME 18 - #define SSH_FXP_READLINK 19 - #define SSH_FXP_SYMLINK 20 - #define SSH_FXP_STATUS 101 - #define SSH_FXP_HANDLE 102 - #define SSH_FXP_DATA 103 - #define SSH_FXP_NAME 104 - #define SSH_FXP_ATTRS 105 - #define SSH_FXP_EXTENDED 200 - #define SSH_FXP_EXTENDED_REPLY 201 - - Additional packet types should only be defined if the protocol - version number (see Section ``Protocol Initialization'') is - incremented, and their use MUST be negotiated using the version - number.

Protocol Initialization - - When the file transfer protocol starts, it first sends a SSH_FXP_INIT - (including its version number) packet to the server. The server - responds with a SSH_FXP_VERSION packet, supplying the lowest of its - own and the client's version number. Both parties should from then - on adhere to particular version of the protocol. - - The SSH_FXP_INIT packet (from client to server) has the following - data: - - uint32 version - <extension data> - - The SSH_FXP_VERSION packet (from server to client) has the following - data: - - uint32 version - <extension data> - - The version number of the protocol specified in this document is 3. - The version number should be incremented for each incompatible - revision of this protocol. - - The extension data in the above packets may be empty, or may be a - sequence of - - string extension_name - string extension_data - - pairs (both strings MUST always be present if one is, but the - `extension_data' string may be of zero length). If present, these - strings indicate extensions to the baseline protocol. The - `extension_name' field(s) identify the name of the extension. The - name should be of the form "name@domain", where the domain is the DNS - domain name of the organization defining the extension. Additional - names that are not of this format may be defined later by the IETF. - Implementations MUST silently ignore any extensions whose name they - do not recognize. - - - - - - - - - - - - -Ylonen & Lehtinen Expires April 1, 2002 [Page 7] - -Internet-Draft SSH File Transfer Protocol October 2001 - - -5. File Attributes - - A new compound data type is defined for encoding file attributes. It - is basically just a combination of elementary types, but is defined - once because of the non-trivial description of the fields and to - ensure maintainability. - - The same encoding is used both when returning file attributes from - the server and when sending file attributes to the server. When - sending it to the server, the flags field specifies which attributes - are included, and the server will use default values for the - remaining attributes (or will not modify the values of remaining - attributes). When receiving attributes from the server, the flags - specify which attributes are included in the returned data. The - server normally returns all attributes it knows about. - - uint32 flags - uint64 size present only if flag SSH_FILEXFER_ATTR_SIZE - uint32 uid present only if flag SSH_FILEXFER_ATTR_UIDGID - uint32 gid present only if flag SSH_FILEXFER_ATTR_UIDGID - uint32 permissions present only if flag SSH_FILEXFER_ATTR_PERMISSIONS - uint32 atime present only if flag SSH_FILEXFER_ACMODTIME - uint32 mtime present only if flag SSH_FILEXFER_ACMODTIME - uint32 extended_count present only if flag SSH_FILEXFER_ATTR_EXTENDED - string extended_type - string extended_data - ... more extended data (extended_type - extended_data pairs), - so that number of pairs equals extended_count - - The `flags' specify which of the fields are present. Those fields - for which the corresponding flag is not set are not present (not - included in the packet). New flags can only be added by incrementing - the protocol version number (or by using the extension mechanism - described below). - - The `size' field specifies the size of the file in bytes. - - The `uid' and `gid' fields contain numeric Unix-like user and group - identifiers, respectively. - - The `permissions' field contains a bit mask of file permissions as - defined by posix [1]. - - The `atime' and `mtime' contain the access and modification times of - the files, respectively. They are represented as seconds from Jan 1, - 1970 in UTC. - - The SSH_FILEXFER_ATTR_EXTENDED flag provides a general extension - - - -Ylonen & Lehtinen Expires April 1, 2002 [Page 8] - -Internet-Draft SSH File Transfer Protocol October 2001 - - - mechanism for vendor-specific extensions. If the flag is specified, - then the `extended_count' field is present. It specifies the number - of extended_type-extended_data pairs that follow. Each of these - pairs specifies an extended attribute. For each of the attributes, - the extended_type field should be a string of the format - "name@domain", where "domain" is a valid, registered domain name and - "name" identifies the method. The IETF may later standardize certain - names that deviate from this format (e.g., that do not contain the - "@" sign). The interpretation of `extended_data' depends on the - type. Implementations SHOULD ignore extended data fields that they - do not understand. - - Additional fields can be added to the attributes by either defining - additional bits to the flags field to indicate their presence, or by - defining extended attributes for them. The extended attributes - mechanism is recommended for most purposes; additional flags bits - should only be defined by an IETF standards action that also - increments the protocol version number. The use of such new fields - MUST be negotiated by the version number in the protocol exchange. - It is a protocol error if a packet with unsupported protocol bits is - received. - - The flags bits are defined to have the following values: - - #define SSH_FILEXFER_ATTR_SIZE 0x00000001 - #define SSH_FILEXFER_ATTR_UIDGID 0x00000002 - #define SSH_FILEXFER_ATTR_PERMISSIONS 0x00000004 - #define SSH_FILEXFER_ATTR_ACMODTIME 0x00000008 - #define SSH_FILEXFER_ATTR_EXTENDED 0x80000000 - - - - - - - - - - - - - - - - - - - - - - -Ylonen & Lehtinen Expires April 1, 2002 [Page 9] - -Internet-Draft SSH File Transfer Protocol October 2001 - - -6. Requests From the Client to the Server - - Requests from the client to the server represent the various file - system operations. Each request begins with an `id' field, which is - a 32-bit identifier identifying the request (selected by the client). - The same identifier will be returned in the response to the request. - One possible implementation of it is a monotonically increasing - request sequence number (modulo 2^32). - - Many operations in the protocol operate on open files. The - SSH_FXP_OPEN request can return a file handle (which is an opaque - variable-length string) which may be used to access the file later - (e.g. in a read operation). The client MUST NOT send requests the - server with bogus or closed handles. However, the server MUST - perform adequate checks on the handle in order to avoid security - risks due to fabricated handles. - - This design allows either stateful and stateless server - implementation, as well as an implementation which caches state - between requests but may also flush it. The contents of the file - handle string are entirely up to the server and its design. The - client should not modify or attempt to interpret the file handle - strings. - - The file handle strings MUST NOT be longer than 256 bytes. - -6.1 Request Synchronization and Reordering - - The protocol and implementations MUST process requests relating to - the same file in the order in which they are received. In other - words, if an application submits multiple requests to the server, the - results in the responses will be the same as if it had sent the - requests one at a time and waited for the response in each case. For - example, the server may process non-overlapping read/write requests - to the same file in parallel, but overlapping reads and writes cannot - be reordered or parallelized. However, there are no ordering - restrictions on the server for processing requests from two different - file transfer connections. The server may interleave and parallelize - them at will. - - There are no restrictions on the order in which responses to - outstanding requests are delivered to the client, except that the - server must ensure fairness in the sense that processing of no - request will be indefinitely delayed even if the client is sending - other requests so that there are multiple outstanding requests all - the time. - - - - - -Ylonen & Lehtinen Expires April 1, 2002 [Page 10] - -Internet-Draft SSH File Transfer Protocol October 2001 - - -6.2 File Names - - This protocol represents file names as strings. File names are - assumed to use the slash ('/') character as a directory separator. - - File names starting with a slash are "absolute", and are relative to - the root of the file system. Names starting with any other character - are relative to the user's default directory (home directory). Note - that identifying the user is assumed to take place outside of this - protocol. - - Servers SHOULD interpret a path name component ".." as referring to - the parent directory, and "." as referring to the current directory. - If the server implementation limits access to certain parts of the - file system, it must be extra careful in parsing file names when - enforcing such restrictions. There have been numerous reported - security bugs where a ".." in a path name has allowed access outside - the intended area. - - An empty path name is valid, and it refers to the user's default - directory (usually the user's home directory). - - Otherwise, no syntax is defined for file names by this specification. - Clients should not make any other assumptions; however, they can - splice path name components returned by SSH_FXP_READDIR together - using a slash ('/') as the separator, and that will work as expected. - - It is understood that the lack of well-defined semantics for file - names may cause interoperability problems between clients and servers - using radically different operating systems. However, this approach - is known to work acceptably with most systems, and alternative - approaches that e.g. treat file names as sequences of structured - components are quite complicated. - -6.3 Opening, Creating, and Closing Files - - Files are opened and created using the SSH_FXP_OPEN message, whose - data part is as follows: - - uint32 id - string filename - uint32 pflags - ATTRS attrs - - The `id' field is the request identifier as for all requests. - - The `filename' field specifies the file name. See Section ``File - Names'' for more information. - - - -Ylonen & Lehtinen Expires April 1, 2002 [Page 11] - -Internet-Draft SSH File Transfer Protocol October 2001 - - - The `pflags' field is a bitmask. The following bits have been - defined. - - #define SSH_FXF_READ 0x00000001 - #define SSH_FXF_WRITE 0x00000002 - #define SSH_FXF_APPEND 0x00000004 - #define SSH_FXF_CREAT 0x00000008 - #define SSH_FXF_TRUNC 0x00000010 - #define SSH_FXF_EXCL 0x00000020 - - These have the following meanings: - - SSH_FXF_READ - Open the file for reading. - - SSH_FXF_WRITE - Open the file for writing. If both this and SSH_FXF_READ are - specified, the file is opened for both reading and writing. - - SSH_FXF_APPEND - Force all writes to append data at the end of the file. - - SSH_FXF_CREAT - If this flag is specified, then a new file will be created if one - does not already exist (if O_TRUNC is specified, the new file will - be truncated to zero length if it previously exists). - - SSH_FXF_TRUNC - Forces an existing file with the same name to be truncated to zero - length when creating a file by specifying SSH_FXF_CREAT. - SSH_FXF_CREAT MUST also be specified if this flag is used. - - SSH_FXF_EXCL - Causes the request to fail if the named file already exists. - SSH_FXF_CREAT MUST also be specified if this flag is used. - - The `attrs' field specifies the initial attributes for the file. - Default values will be used for those attributes that are not - specified. See Section ``File Attributes'' for more information. - - Regardless the server operating system, the file will always be - opened in "binary" mode (i.e., no translations between different - character sets and newline encodings). - - The response to this message will be either SSH_FXP_HANDLE (if the - operation is successful) or SSH_FXP_STATUS (if the operation fails). - - - - - -Ylonen & Lehtinen Expires April 1, 2002 [Page 12] - -Internet-Draft SSH File Transfer Protocol October 2001 - - - A file is closed by using the SSH_FXP_CLOSE request. Its data field - has the following format: - - uint32 id - string handle - - where `id' is the request identifier, and `handle' is a handle - previously returned in the response to SSH_FXP_OPEN or - SSH_FXP_OPENDIR. The handle becomes invalid immediately after this - request has been sent. - - The response to this request will be a SSH_FXP_STATUS message. One - should note that on some server platforms even a close can fail. - This can happen e.g. if the server operating system caches writes, - and an error occurs while flushing cached writes during the close. - -6.4 Reading and Writing - - Once a file has been opened, it can be read using the SSH_FXP_READ - message, which has the following format: - - uint32 id - string handle - uint64 offset - uint32 len - - where `id' is the request identifier, `handle' is an open file handle - returned by SSH_FXP_OPEN, `offset' is the offset (in bytes) relative - to the beginning of the file from where to start reading, and `len' - is the maximum number of bytes to read. - - In response to this request, the server will read as many bytes as it - can from the file (up to `len'), and return them in a SSH_FXP_DATA - message. If an error occurs or EOF is encountered before reading any - data, the server will respond with SSH_FXP_STATUS. For normal disk - files, it is guaranteed that this will read the specified number of - bytes, or up to end of file. For e.g. device files this may return - fewer bytes than requested. - - Writing to a file is achieved using the SSH_FXP_WRITE message, which - has the following format: - - uint32 id - string handle - uint64 offset - string data - - where `id' is a request identifier, `handle' is a file handle - - - -Ylonen & Lehtinen Expires April 1, 2002 [Page 13] - -Internet-Draft SSH File Transfer Protocol October 2001 - - - returned by SSH_FXP_OPEN, `offset' is the offset (in bytes) from the - beginning of the file where to start writing, and `data' is the data - to be written. - - The write will extend the file if writing beyond the end of the file. - It is legal to write way beyond the end of the file; the semantics - are to write zeroes from the end of the file to the specified offset - and then the data. On most operating systems, such writes do not - allocate disk space but instead leave "holes" in the file. - - The server responds to a write request with a SSH_FXP_STATUS message. - -6.5 Removing and Renaming Files - - Files can be removed using the SSH_FXP_REMOVE message. It has the - following format: - - uint32 id - string filename - - where `id' is the request identifier and `filename' is the name of - the file to be removed. See Section ``File Names'' for more - information. This request cannot be used to remove directories. - - The server will respond to this request with a SSH_FXP_STATUS - message. - - Files (and directories) can be renamed using the SSH_FXP_RENAME - message. Its data is as follows: - - uint32 id - string oldpath - string newpath - - where `id' is the request identifier, `oldpath' is the name of an - existing file or directory, and `newpath' is the new name for the - file or directory. It is an error if there already exists a file - with the name specified by newpath. The server may also fail rename - requests in other situations, for example if `oldpath' and `newpath' - point to different file systems on the server. - - The server will respond to this request with a SSH_FXP_STATUS - message. - - - - - - - - -Ylonen & Lehtinen Expires April 1, 2002 [Page 14] - -Internet-Draft SSH File Transfer Protocol October 2001 - - -6.6 Creating and Deleting Directories - - New directories can be created using the SSH_FXP_MKDIR request. It - has the following format: - - uint32 id - string path - ATTRS attrs - - where `id' is the request identifier, `path' and `attrs' specifies - the modifications to be made to its attributes. See Section ``File - Names'' for more information on file names. Attributes are discussed - in more detail in Section ``File Attributes''. specifies the - directory to be created. An error will be returned if a file or - directory with the specified path already exists. The server will - respond to this request with a SSH_FXP_STATUS message. - - Directories can be removed using the SSH_FXP_RMDIR request, which - has the following format: - - uint32 id - string path - - where `id' is the request identifier, and `path' specifies the - directory to be removed. See Section ``File Names'' for more - information on file names. An error will be returned if no directory - with the specified path exists, or if the specified directory is not - empty, or if the path specified a file system object other than a - directory. The server responds to this request with a SSH_FXP_STATUS - message. - -6.7 Scanning Directories - - The files in a directory can be listed using the SSH_FXP_OPENDIR and - SSH_FXP_READDIR requests. Each SSH_FXP_READDIR request returns one - or more file names with full file attributes for each file. The - client should call SSH_FXP_READDIR repeatedly until it has found the - file it is looking for or until the server responds with a - SSH_FXP_STATUS message indicating an error (normally SSH_FX_EOF if - there are no more files in the directory). The client should then - close the handle using the SSH_FXP_CLOSE request. - - - - - - - - - - -Ylonen & Lehtinen Expires April 1, 2002 [Page 15] - -Internet-Draft SSH File Transfer Protocol October 2001 - - - The SSH_FXP_OPENDIR opens a directory for reading. It has the - following format: - - uint32 id - string path - - where `id' is the request identifier and `path' is the path name of - the directory to be listed (without any trailing slash). See Section - ``File Names'' for more information on file names. This will return - an error if the path does not specify a directory or if the directory - is not readable. The server will respond to this request with either - a SSH_FXP_HANDLE or a SSH_FXP_STATUS message. - - Once the directory has been successfully opened, files (and - directories) contained in it can be listed using SSH_FXP_READDIR - requests. These are of the format - - uint32 id - string handle - - where `id' is the request identifier, and `handle' is a handle - returned by SSH_FXP_OPENDIR. (It is a protocol error to attempt to - use an ordinary file handle returned by SSH_FXP_OPEN.) - - The server responds to this request with either a SSH_FXP_NAME or a - SSH_FXP_STATUS message. One or more names may be returned at a time. - Full status information is returned for each name in order to speed - up typical directory listings. - - When the client no longer wishes to read more names from the - directory, it SHOULD call SSH_FXP_CLOSE for the handle. The handle - should be closed regardless of whether an error has occurred or not. - -6.8 Retrieving File Attributes - - Very often, file attributes are automatically returned by - SSH_FXP_READDIR. However, sometimes there is need to specifically - retrieve the attributes for a named file. This can be done using the - SSH_FXP_STAT, SSH_FXP_LSTAT and SSH_FXP_FSTAT requests. - - SSH_FXP_STAT and SSH_FXP_LSTAT only differ in that SSH_FXP_STAT - follows symbolic links on the server, whereas SSH_FXP_LSTAT does not - follow symbolic links. Both have the same format: - - uint32 id - string path - - where `id' is the request identifier, and `path' specifies the file - - - -Ylonen & Lehtinen Expires April 1, 2002 [Page 16] - -Internet-Draft SSH File Transfer Protocol October 2001 - - - system object for which status is to be returned. The server - responds to this request with either SSH_FXP_ATTRS or SSH_FXP_STATUS. - - SSH_FXP_FSTAT differs from the others in that it returns status - information for an open file (identified by the file handle). Its - format is as follows: - - uint32 id - string handle - - where `id' is the request identifier and `handle' is a file handle - returned by SSH_FXP_OPEN. The server responds to this request with - SSH_FXP_ATTRS or SSH_FXP_STATUS. - -6.9 Setting File Attributes - - File attributes may be modified using the SSH_FXP_SETSTAT and - SSH_FXP_FSETSTAT requests. These requests are used for operations - such as changing the ownership, permissions or access times, as well - as for truncating a file. - - The SSH_FXP_SETSTAT request is of the following format: - - uint32 id - string path - ATTRS attrs - - where `id' is the request identifier, `path' specifies the file - system object (e.g. file or directory) whose attributes are to be - modified, and `attrs' specifies the modifications to be made to its - attributes. Attributes are discussed in more detail in Section - ``File Attributes''. - - An error will be returned if the specified file system object does - not exist or the user does not have sufficient rights to modify the - specified attributes. The server responds to this request with a - SSH_FXP_STATUS message. - - The SSH_FXP_FSETSTAT request modifies the attributes of a file which - is already open. It has the following format: - - uint32 id - string handle - ATTRS attrs - - where `id' is the request identifier, `handle' (MUST be returned by - SSH_FXP_OPEN) identifies the file whose attributes are to be - modified, and `attrs' specifies the modifications to be made to its - - - -Ylonen & Lehtinen Expires April 1, 2002 [Page 17] - -Internet-Draft SSH File Transfer Protocol October 2001 - - - attributes. Attributes are discussed in more detail in Section - ``File Attributes''. The server will respond to this request with - SSH_FXP_STATUS. - -6.10 Dealing with Symbolic links - - The SSH_FXP_READLINK request may be used to read the target of a - symbolic link. It would have a data part as follows: - - uint32 id - string path - - where `id' is the request identifier and `path' specifies the path - name of the symlink to be read. - - The server will respond with a SSH_FXP_NAME packet containing only - one name and a dummy attributes value. The name in the returned - packet contains the target of the link. If an error occurs, the - server may respond with SSH_FXP_STATUS. - - The SSH_FXP_SYMLINK request will create a symbolic link on the - server. It is of the following format - - uint32 id - string linkpath - string targetpath - - where `id' is the request identifier, `linkpath' specifies the path - name of the symlink to be created and `targetpath' specifies the - target of the symlink. The server shall respond with a - SSH_FXP_STATUS indicating either success (SSH_FX_OK) or an error - condition. - -6.11 Canonicalizing the Server-Side Path Name - - The SSH_FXP_REALPATH request can be used to have the server - canonicalize any given path name to an absolute path. This is useful - for converting path names containing ".." components or relative - pathnames without a leading slash into absolute paths. The format of - the request is as follows: - - uint32 id - string path - - where `id' is the request identifier and `path' specifies the path - name to be canonicalized. The server will respond with a - SSH_FXP_NAME packet containing only one name and a dummy attributes - value. The name is the returned packet will be in canonical form. - - - -Ylonen & Lehtinen Expires April 1, 2002 [Page 18] - -Internet-Draft SSH File Transfer Protocol October 2001 - - - If an error occurs, the server may also respond with SSH_FXP_STATUS. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -Ylonen & Lehtinen Expires April 1, 2002 [Page 19] - -Internet-Draft SSH File Transfer Protocol October 2001 - - -7. Responses from the Server to the Client - - The server responds to the client using one of a few response - packets. All requests can return a SSH_FXP_STATUS response upon - failure. When the operation is successful, any of the responses may - be returned (depending on the operation). If no data needs to be - returned to the client, the SSH_FXP_STATUS response with SSH_FX_OK - status is appropriate. Otherwise, the SSH_FXP_HANDLE message is used - to return a file handle (for SSH_FXP_OPEN and SSH_FXP_OPENDIR - requests), SSH_FXP_DATA is used to return data from SSH_FXP_READ, - SSH_FXP_NAME is used to return one or more file names from a - SSH_FXP_READDIR or SSH_FXP_REALPATH request, and SSH_FXP_ATTRS is - used to return file attributes from SSH_FXP_STAT, SSH_FXP_LSTAT, and - SSH_FXP_FSTAT requests. - - Exactly one response will be returned for each request. Each - response packet contains a request identifier which can be used to - match each response with the corresponding request. Note that it is - legal to have several requests outstanding simultaneously, and the - server is allowed to send responses to them in a different order from - the order in which the requests were sent (the result of their - execution, however, is guaranteed to be as if they had been processed - one at a time in the order in which the requests were sent). - - Response packets are of the same general format as request packets. - Each response packet begins with the request identifier. - - The format of the data portion of the SSH_FXP_STATUS response is as - follows: - - uint32 id - uint32 error/status code - string error message (ISO-10646 UTF-8 [RFC-2279]) - string language tag (as defined in [RFC-1766]) - - where `id' is the request identifier, and `error/status code' - indicates the result of the requested operation. The value SSH_FX_OK - indicates success, and all other values indicate failure. - - - - - - - - - - - - - -Ylonen & Lehtinen Expires April 1, 2002 [Page 20] - -Internet-Draft SSH File Transfer Protocol October 2001 - - - Currently, the following values are defined (other values may be - defined by future versions of this protocol): - - #define SSH_FX_OK 0 - #define SSH_FX_EOF 1 - #define SSH_FX_NO_SUCH_FILE 2 - #define SSH_FX_PERMISSION_DENIED 3 - #define SSH_FX_FAILURE 4 - #define SSH_FX_BAD_MESSAGE 5 - #define SSH_FX_NO_CONNECTION 6 - #define SSH_FX_CONNECTION_LOST 7 - #define SSH_FX_OP_UNSUPPORTED 8 - - SSH_FX_OK - Indicates successful completion of the operation. - - SSH_FX_EOF - indicates end-of-file condition; for SSH_FX_READ it means that no - more data is available in the file, and for SSH_FX_READDIR it - indicates that no more files are contained in the directory. - - SSH_FX_NO_SUCH_FILE - is returned when a reference is made to a file which should exist - but doesn't. - - SSH_FX_PERMISSION_DENIED - is returned when the authenticated user does not have sufficient - permissions to perform the operation. - - SSH_FX_FAILURE - is a generic catch-all error message; it should be returned if an - error occurs for which there is no more specific error code - defined. - - SSH_FX_BAD_MESSAGE - may be returned if a badly formatted packet or protocol - incompatibility is detected. - - SSH_FX_NO_CONNECTION - is a pseudo-error which indicates that the client has no - connection to the server (it can only be generated locally by the - client, and MUST NOT be returned by servers). - - SSH_FX_CONNECTION_LOST - is a pseudo-error which indicates that the connection to the - server has been lost (it can only be generated locally by the - client, and MUST NOT be returned by servers). - - - - -Ylonen & Lehtinen Expires April 1, 2002 [Page 21] - -Internet-Draft SSH File Transfer Protocol October 2001 - - - SSH_FX_OP_UNSUPPORTED - indicates that an attempt was made to perform an operation which - is not supported for the server (it may be generated locally by - the client if e.g. the version number exchange indicates that a - required feature is not supported by the server, or it may be - returned by the server if the server does not implement an - operation). - - The SSH_FXP_HANDLE response has the following format: - - uint32 id - string handle - - where `id' is the request identifier, and `handle' is an arbitrary - string that identifies an open file or directory on the server. The - handle is opaque to the client; the client MUST NOT attempt to - interpret or modify it in any way. The length of the handle string - MUST NOT exceed 256 data bytes. - - The SSH_FXP_DATA response has the following format: - - uint32 id - string data - - where `id' is the request identifier, and `data' is an arbitrary byte - string containing the requested data. The data string may be at most - the number of bytes requested in a SSH_FXP_READ request, but may also - be shorter if end of file is reached or if the read is from something - other than a regular file. - - The SSH_FXP_NAME response has the following format: - - uint32 id - uint32 count - repeats count times: - string filename - string longname - ATTRS attrs - - where `id' is the request identifier, `count' is the number of names - returned in this response, and the remaining fields repeat `count' - times (so that all three fields are first included for the first - file, then for the second file, etc). In the repeated part, - `filename' is a file name being returned (for SSH_FXP_READDIR, it - will be a relative name within the directory, without any path - components; for SSH_FXP_REALPATH it will be an absolute path name), - `longname' is an expanded format for the file name, similar to what - is returned by "ls -l" on Unix systems, and `attrs' is the attributes - - - -Ylonen & Lehtinen Expires April 1, 2002 [Page 22] - -Internet-Draft SSH File Transfer Protocol October 2001 - - - of the file as described in Section ``File Attributes''. - - The format of the `longname' field is unspecified by this protocol. - It MUST be suitable for use in the output of a directory listing - command (in fact, the recommended operation for a directory listing - command is to simply display this data). However, clients SHOULD NOT - attempt to parse the longname field for file attributes; they SHOULD - use the attrs field instead. - - The recommended format for the longname field is as follows: - - -rwxr-xr-x 1 mjos staff 348911 Mar 25 14:29 t-filexfer - 1234567890 123 12345678 12345678 12345678 123456789012 - - Here, the first line is sample output, and the second field indicates - widths of the various fields. Fields are separated by spaces. The - first field lists file permissions for user, group, and others; the - second field is link count; the third field is the name of the user - who owns the file; the fourth field is the name of the group that - owns the file; the fifth field is the size of the file in bytes; the - sixth field (which actually may contain spaces, but is fixed to 12 - characters) is the file modification time, and the seventh field is - the file name. Each field is specified to be a minimum of certain - number of character positions (indicated by the second line above), - but may also be longer if the data does not fit in the specified - length. - - The SSH_FXP_ATTRS response has the following format: - - uint32 id - ATTRS attrs - - where `id' is the request identifier, and `attrs' is the returned - file attributes as described in Section ``File Attributes''. - - - - - - - - - - - - - - - - - -Ylonen & Lehtinen Expires April 1, 2002 [Page 23] - -Internet-Draft SSH File Transfer Protocol October 2001 - - -8. Vendor-Specific Extensions - - The SSH_FXP_EXTENDED request provides a generic extension mechanism - for adding vendor-specific commands. The request has the following - format: - - uint32 id - string extended-request - ... any request-specific data ... - - where `id' is the request identifier, and `extended-request' is a - string of the format "name@domain", where domain is an internet - domain name of the vendor defining the request. The rest of the - request is completely vendor-specific, and servers should only - attempt to interpret it if they recognize the `extended-request' - name. - - The server may respond to such requests using any of the response - packets defined in Section ``Responses from the Server to the - Client''. Additionally, the server may also respond with a - SSH_FXP_EXTENDED_REPLY packet, as defined below. If the server does - not recognize the `extended-request' name, then the server MUST - respond with SSH_FXP_STATUS with error/status set to - SSH_FX_OP_UNSUPPORTED. - - The SSH_FXP_EXTENDED_REPLY packet can be used to carry arbitrary - extension-specific data from the server to the client.

Expires April 16, 2003 [Page 2] - -Internet-Draft SSH File Transfer Protocol October 2002 - - -1. Introduction - - This protocol provides secure file transfer (and more generally file - system access) functionality over a reliable data stream, such as a - channel in the SSH2 protocol [5]. - - This protocol is designed so that it could be used to implement a - secure remote file system service, as well as a secure file transfer - service. - - This protocol assumes that it runs over a secure channel, and that - the server has already authenticated the user at the client end, and - that the identity of the client user is externally available to the - server implementation. - - In general, this protocol follows a simple request-response model. - Each request and response contains a sequence number and multiple - requests may be pending simultaneously. There are a relatively large - number of different request messages, but a small number of possible - response messages. Each request has one or more response messages - that may be returned in result (e.g., a read either returns data or - reports error status). - - The packet format descriptions in this specification follow the - notation presented in the secsh architecture draft. [5] - - Even though this protocol is described in the context of the SSH2 - protocol, this protocol is general and independent of the rest of the - SSH2 protocol suite. It could be used in a number of different - applications, such as secure file transfer over TLS RFC 2246 [1] and - transfer of management information in VPN applications. - - - - - - - - - - - - - - - - - - - - -Galbraith, et al. Expires April 16, 2003 [Page 3] - -Internet-Draft SSH File Transfer Protocol October 2002 - - -2. Use with the SSH Connection Protocol - - When used with the SSH2 Protocol suite, this protocol is intended to - be used from the SSH Connection Protocol [7] as a subsystem, as - described in section ``Starting a Shell or a Command''. The - subsystem name used with this protocol is "sftp". - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -Galbraith, et al. Expires April 16, 2003 [Page 4] - -Internet-Draft SSH File Transfer Protocol October 2002 - - -3. General Packet Format - - All packets transmitted over the secure connection are of the - following format: - - uint32 length - byte type - byte[length - 1] data payload - - That is, they are just data preceded by 32-bit length and 8-bit type - fields. The `length' is the length of the data area, and does not - include the `length' field itself. The format and interpretation of - the data area depends on the packet type. - - All packet descriptions below only specify the packet type and the - data that goes into the data field. Thus, they should be prefixed by - the `length' and `type' fields. - - The maximum size of a packet is in practice determined by the client - (the maximum size of read or write requests that it sends, plus a few - bytes of packet overhead). All servers SHOULD support packets of at - least 34000 bytes (where the packet size refers to the full length, - including the header above). This should allow for reads and writes - of at most 32768 bytes. - - There is no limit on the number of outstanding (non-acknowledged) - requests that the client may send to the server. In practice this is - limited by the buffering available on the data stream and the queuing - performed by the server. If the server's queues are full, it should - not read any more data from the stream, and flow control will prevent - the client from sending more requests. Note, however, that while - there is no restriction on the protocol level, the client's API may - provide a limit in order to prevent infinite queuing of outgoing - requests at the client. - - The following values are defined for packet types. - - - - - - - - - - - - - - - -Galbraith, et al.

Protocol Initialization - - When the file transfer protocol starts, the client first sends a - SSH_FXP_INIT (including its version number) packet to the server. - The server responds with a SSH_FXP_VERSION packet, supplying the - lowest of its own and the client's version number. Both parties - should from then on adhere to particular version of the protocol. - - The version number of the protocol specified in this document is 4. - The version number should be incremented for each incompatible - revision of this protocol. - -4.1 Client Initialization - - The SSH_FXP_INIT packet (from client to server) has the following - data: - - uint32 version - - Version 3 of this protocol allowed clients to include extensions in - the SSH_FXP_INIT packet; however, this can cause interoperability - problems with version 1 and version 2 servers because the client must - send this packet before knowing the servers version. - - In this version of the protocol, clients MUST use the - SSH_FXP_EXTENDED packet to send extensions to the server after - version exchange has completed. Clients MUST NOT include extensions - in the version packet. This will prevent interoperability problems - with older servers - -4.2 Server Initialization - - The SSH_FXP_VERSION packet (from server to client) has the following - data: - - uint32 version - <extension data> - - 'version' is the lower of the protocol version supported by the - server and the version number received from the client. - - The extension data may be empty, or may be a sequence of - - string extension_name - string extension_data - - pairs (both strings MUST always be present if one is, but the - `extension_data' string may be of zero length). If present, these - - - -Galbraith, et al. Expires April 16, 2003 [Page 7] - -Internet-Draft SSH File Transfer Protocol October 2002 - - - strings indicate extensions to the baseline protocol.

Many clients implemented some sort of - conversion algorithm, but without either a 'canonical' on the wire - format or knowledge of the servers newline convention, correct - conversion was not always possible. - - Starting with Version 4, the SSH_FXF_TEXT file open flag (Section - 6.3) makes it possible to request that the server translate a file to - a 'canonical' on the wire format. This format uses \r\n as the line - separator. - - Servers for systems using multiple newline characters (for example, - Mac OS X or VMS) or systems using counted records, MUST translate to - the canonical form. - - However, to ease the burden of implementation on servers that use a - single, simple separator sequence, the following extension allows the - canonical format to be changed. - - string "newline" - string new-canonical-separator (usually "\r" or "\n" or "\r\n") - - All clients MUST support this extension. - - When processing text files, clients SHOULD NOT translate any - character or sequence that is not an exact match of the servers - newline separator. - - In particular, if the newline sequence being used is the canonical - "\r\n" sequence, a lone \r or a lone \n SHOULD be written through - without change. - - - - - -Galbraith, et al.

File Attributes - - A new compound data type is defined for encoding file attributes. - The same encoding is used both when returning file attributes from - the server and when sending file attributes to the server. When - sending it to the server, the flags field specifies which attributes - are included, and the server will use default values for the - remaining attributes (or will not modify the values of remaining - attributes). When receiving attributes from the server, the flags - specify which attributes are included in the returned data. The - server normally returns all attributes it knows about. - - uint32 flags - byte type always present - uint64 size present only if flag SSH_FILEXFER_ATTR_SIZE - string owner present only if flag SSH_FILEXFER_ATTR_OWNERGROUP - string group present only if flag SSH_FILEXFER_ATTR_OWNERGROUP - uint32 permissions present only if flag SSH_FILEXFER_ATTR_PERMISSIONS - uint32 atime present only if flag SSH_FILEXFER_ATTR_ACCESSTIME - uint32 createtime present only if flag SSH_FILEXFER_ATTR_CREATETIME - uint32 mtime present only if flag SSH_FILEXFER_ATTR_MODIFYTIME - string acl present only if flag SSH_FILEXFER_ATTR_ACL - uint32 extended_count present only if flag SSH_FILEXFER_ATTR_EXTENDED - string extended_type - string extended_data - ... more extended data (extended_type - extended_data pairs), - so that number of pairs equals extended_count - - -5.1 Flags - - The `flags' specify which of the fields are present. Those fields - for which the corresponding flag is not set are not present (not - included in the packet). New flags can only be added by incrementing - the protocol version number (or by using the extension mechanism - described below). - - The flags bits are defined to have the following values: - - #define SSH_FILEXFER_ATTR_SIZE 0x00000001 - #define SSH_FILEXFER_ATTR_PERMISSIONS 0x00000004 - #define SSH_FILEXFER_ATTR_ACCESSTIME 0x00000008 - #define SSH_FILEXFER_ATTR_CREATETIME 0x00000010 - #define SSH_FILEXFER_ATTR_MODIFYTIME 0x00000020 - #define SSH_FILEXFER_ATTR_ACL 0x00000040 - #define SSH_FILEXFER_ATTR_OWNERGROUP 0x00000080 - #define SSH_FILEXFER_ATTR_EXTENDED 0x80000000 - - - - -Galbraith, et al.

In the case where there is no - translation available to the client or server, the attribute value - must be constructed without the "@". Therefore, the absence of the @ - from the owner or owner_group attribute signifies that no translation - was available and the receiver of the attribute should not place any - special meaning with the attribute value.

If the flag is specified, - then the `extended_count' field is present. It specifies the number - of extended_type-extended_data pairs that follow. Each of these - pairs specifies an extended attribute. For each of the attributes, - the extended_type field should be a string of the format - "name@domain", where "domain" is a valid, registered domain name and - "name" identifies the method. The IETF may later standardize certain - names that deviate from this format (e.g., that do not contain the - "@" sign). The interpretation of `extended_data' depends on the - type. Implementations SHOULD ignore extended data fields that they - do not understand. - - Additional fields can be added to the attributes by either defining - additional bits to the flags field to indicate their presence, or by - defining extended attributes for them. The extended attributes - mechanism is recommended for most purposes; additional flags bits - should only be defined by an IETF standards action that also - increments the protocol version number. The use of such new fields - MUST be negotiated by the version number in the protocol exchange. - It is a protocol error if a packet with unsupported protocol bits is - received. - - - - - - -Galbraith, et al. Expires April 16, 2003 [Page 12] - -Internet-Draft SSH File Transfer Protocol October 2002 - - -6. Requests From the Client to the Server - - Requests from the client to the server represent the various file - system operations. Each request begins with an `id' field, which is - a 32-bit identifier identifying the request (selected by the client). - The same identifier will be returned in the response to the request. - One possible implementation is a monotonically increasing request - sequence number (modulo 2^32). - - Many operations in the protocol operate on open files. The - SSH_FXP_OPEN request can return a file handle (which is an opaque - variable-length string) which may be used to access the file later - (e.g. in a read operation). The client MUST NOT send requests the - server with bogus or closed handles. However, the server MUST - perform adequate checks on the handle in order to avoid security - risks due to fabricated handles. - - This design allows either stateful and stateless server - implementation, as well as an implementation which caches state - between requests but may also flush it. The contents of the file - handle string are entirely up to the server and its design. The - client should not modify or attempt to interpret the file handle - strings. - - The file handle strings MUST NOT be longer than 256 bytes. - -6.1 Request Synchronization and Reordering - - The protocol and implementations MUST process requests relating to - the same file in the order in which they are received. In other - words, if an application submits multiple requests to the server, the - results in the responses will be the same as if it had sent the - requests one at a time and waited for the response in each case. For - example, the server may process non-overlapping read/write requests - to the same file in parallel, but overlapping reads and writes cannot - be reordered or parallelized. However, there are no ordering - restrictions on the server for processing requests from two different - file transfer connections. The server may interleave and parallelize - them at will. - - There are no restrictions on the order in which responses to - outstanding requests are delivered to the client, except that the - server must ensure fairness in the sense that processing of no - request will be indefinitely delayed even if the client is sending - other requests so that there are multiple outstanding requests all - the time. - - - - - -Galbraith, et al. Expires April 16, 2003 [Page 13] - -Internet-Draft SSH File Transfer Protocol October 2002 - - -6.2 File Names - - This protocol represents file names as strings. File names are - assumed to use the slash ('/') character as a directory separator. - - File names starting with a slash are "absolute", and are relative to - the root of the file system. Names starting with any other character - are relative to the user's default directory (home directory). Note - that identifying the user is assumed to take place outside of this - protocol. - - Servers SHOULD interpret a path name component ".." as referring to - the parent directory, and "." as referring to the current directory. - If the server implementation limits access to certain parts of the - file system, it must be extra careful in parsing file names when - enforcing such restrictions. There have been numerous reported - security bugs where a ".." in a path name has allowed access outside - the intended area. - - An empty path name is valid, and it refers to the user's default - directory (usually the user's home directory). - - Otherwise, no syntax is defined for file names by this specification. - Clients should not make any other assumptions; however, they can - splice path name components returned by SSH_FXP_READDIR together - using a slash ('/') as the separator, and that will work as expected. - - In order to comply with IETF Policy on Character Sets and Languages - [2], all filenames are to be encoded in UTF-8. The shortest valid - UTF-8 encoding of the UNICODE data MUST be used. The server is - responsible for converting the UNICODE data to whatever canonical - form it requires. - - For example, if the server requires that precomposed characters - always be used, the server MUST NOT assume the filename as sent by - the client has this attribute, but must do this normalization itself. - - It is understood that the lack of well-defined semantics for file - names may cause interoperability problems between clients and servers - using radically different operating systems. However, this approach - is known to work acceptably with most systems, and alternative - approaches that e.g. treat file names as sequences of structured - components are quite complicated. - -6.3 Opening, Creating, and Closing Files - - Files are opened and created using the SSH_FXP_OPEN message, whose - data part is as follows: - - - -Galbraith, et al.

The server will respond to this request with - SSH_FXP_STATUS. - -6.10 Dealing with Symbolic links - - The SSH_FXP_READLINK request may be used to read the target of a - symbolic link. It would have a data part as follows: - - uint32 id - string path [UTF-8] - - where `id' is the request identifier and `path' specifies the path - name of the symlink to be read. - - The server will respond with a SSH_FXP_NAME packet containing only - one name and a dummy attributes value. The name in the returned - packet contains the target of the link. If an error occurs, the - server may respond with SSH_FXP_STATUS. - - The SSH_FXP_SYMLINK request will create a symbolic link on the - server. It is of the following format - - uint32 id - string linkpath [UTF-8] - string targetpath [UTF-8] - - where `id' is the request identifier, `linkpath' specifies the path - name of the symlink to be created and `targetpath' specifies the - - - -Galbraith, et al. Expires April 16, 2003 [Page 22] - -Internet-Draft SSH File Transfer Protocol October 2002 - - - target of the symlink. The server shall respond with a - SSH_FXP_STATUS indicating either success (SSH_FX_OK) or an error - condition. - -6.11 Canonicalizing the Server-Side Path Name - - The SSH_FXP_REALPATH request can be used to have the server - canonicalize any given path name to an absolute path. This is useful - for converting path names containing ".." components or relative - pathnames without a leading slash into absolute paths. The format of - the request is as follows: - - uint32 id - string path [UTF-8] - - where `id' is the request identifier and `path' specifies the path - name to be canonicalized. The server will respond with a - SSH_FXP_NAME packet containing the name in canonical form and a dummy - attributes value. If an error occurs, the server may also respond - with SSH_FXP_STATUS. - -6.11.1 Best practice for dealing with paths - - The client SHOULD treat the results of SSH_FXP_REALPATH as a - canonical absolute path, even if the path does not appear to be - absolute. A client that use REALPATH(".") and treats the result as - absolute, even if there is no leading slash, will continue to - function correctly, even when talking to a Windows NT or VMS style - system, where absolute paths may not begin with a slash. - - For example, if the client wishes to change directory up, and the - server has returned "c:/x/y/z" from REALPATH, the client SHOULD use - "c:/x/y/z/..". - - As a second example, if the client wishes to open the file "x.txt" in - the current directory, and server has returned "dka100:/x/y/z" as the - canonical path of the directory, the client SHOULD open "dka100:/x/y/ - z/x.txt" - - - - - - - - - - - - - -Galbraith, et al.

Responses from the Server to the Client - - The server responds to the client using one of a few response - packets. All requests can return a SSH_FXP_STATUS response upon - failure. When the operation is successful, any of the responses may - be returned (depending on the operation). If no data needs to be - returned to the client, the SSH_FXP_STATUS response with SSH_FX_OK - status is appropriate. Otherwise, the SSH_FXP_HANDLE message is used - to return a file handle (for SSH_FXP_OPEN and SSH_FXP_OPENDIR - requests), SSH_FXP_DATA is used to return data from SSH_FXP_READ, - SSH_FXP_NAME is used to return one or more file names from a - SSH_FXP_READDIR or SSH_FXP_REALPATH request, and SSH_FXP_ATTRS is - used to return file attributes from SSH_FXP_STAT, SSH_FXP_LSTAT, and - SSH_FXP_FSTAT requests. - - Exactly one response will be returned for each request. Each - response packet contains a request identifier which can be used to - match each response with the corresponding request. Note that it is - legal to have several requests outstanding simultaneously, and the - server is allowed to send responses to them in a different order from - the order in which the requests were sent (the result of their - execution, however, is guaranteed to be as if they had been processed - one at a time in the order in which the requests were sent). - - Response packets are of the same general format as request packets. - Each response packet begins with the request identifier. - - The format of the data portion of the SSH_FXP_STATUS response is as - follows: - - uint32 id - uint32 error/status code - string error message (ISO-10646 UTF-8 [RFC-2279]) - string language tag (as defined in [RFC-1766]) - - where `id' is the request identifier, and `error/status code' - indicates the result of the requested operation.

Vendor-Specific Extensions - - The SSH_FXP_EXTENDED request provides a generic extension mechanism - for adding vendor-specific commands. The request has the following - format: - - uint32 id - string extended-request - ... any request-specific data ... - - where `id' is the request identifier, and `extended-request' is a - string of the format "name@domain", where domain is an internet - domain name of the vendor defining the request. The rest of the - request is completely vendor-specific, and servers should only - attempt to interpret it if they recognize the `extended-request' - name. - - The server may respond to such requests using any of the response - packets defined in Section ``Responses from the Server to the - Client''. Additionally, the server may also respond with a - SSH_FXP_EXTENDED_REPLY packet, as defined below. If the server does - not recognize the `extended-request' name, then the server MUST - respond with SSH_FXP_STATUS with error/status set to - SSH_FX_OP_UNSUPPORTED. - - The SSH_FXP_EXTENDED_REPLY packet can be used to carry arbitrary - extension-specific data from the server to the client. It is of the - following format: - - uint32 id - ... any request-specific data ... - - There is a range of packet types reserved for use by extensions. In - order to avoid collision, extensions that turn on the use of - additional packet types should determine those numbers dynamically. - - The suggested way of doing this is have an extension request from the - client to the server that enables the extension; the extension - response from the server to the client would specify the actual type - values to use, in additional to any other data. - - Extension authors should be mindful of the limited range of packet - types available (there are only 45 values available) and avoid - requiring a new packet type where possible. - - - - - - - -Galbraith, et al.

Introduction - - This protocol provides secure file transfer (and more generally file - system access) functionality over a reliable data stream, such as a - channel in the SSH2 protocol [5]. - - This protocol is designed so that it could be used to implement a - secure remote file system service, as well as a secure file transfer - service. - - This protocol assumes that it runs over a secure channel, and that - the server has already authenticated the user at the client end, and - that the identity of the client user is externally available to the - server implementation. - - In general, this protocol follows a simple request-response model. - Each request and response contains a sequence number and multiple - requests may be pending simultaneously. There are a relatively large - number of different request messages, but a small number of possible - response messages. Each request has one or more response messages - that may be returned in result (e.g., a read either returns data or - reports error status). - - The packet format descriptions in this specification follow the - notation presented in the secsh architecture draft. [5] - - Even though this protocol is described in the context of the SSH2 - protocol, this protocol is general and independent of the rest of the - SSH2 protocol suite. It could be used in a number of different - applications, such as secure file transfer over TLS RFC 2246 [1] and - transfer of management information in VPN applications. - - - - - - - - - - - - - - - - - - - - -Galbraith, et al.

Use with the SSH Connection Protocol - - When used with the SSH2 Protocol suite, this protocol is intended to - be used from the SSH Connection Protocol [7] as a subsystem, as - described in section ``Starting a Shell or a Command''.

Expires June 18, 2003 [Page 4] - -Internet-Draft SSH File Transfer Protocol December 2002 - - -3. General Packet Format - - All packets transmitted over the secure connection are of the - following format: - - uint32 length - byte type - byte[length - 1] data payload - - That is, they are just data preceded by 32-bit length and 8-bit type - fields. The `length' is the length of the data area, and does not - include the `length' field itself. The format and interpretation of - the data area depends on the packet type. - - All packet descriptions below only specify the packet type and the - data that goes into the data field. Thus, they should be prefixed by - the `length' and `type' fields. - - The maximum size of a packet is in practice determined by the client - (the maximum size of read or write requests that it sends, plus a few - bytes of packet overhead). All servers SHOULD support packets of at - least 34000 bytes (where the packet size refers to the full length, - including the header above). This should allow for reads and writes - of at most 32768 bytes. - - There is no limit on the number of outstanding (non-acknowledged) - requests that the client may send to the server. In practice this is - limited by the buffering available on the data stream and the queuing - performed by the server.

Implementations SHOULD ignore extended data fields that they - do not understand. - - Additional fields can be added to the attributes by either defining - additional bits to the flags field to indicate their presence, or by - defining extended attributes for them.

Requests From the Client to the Server - - Requests from the client to the server represent the various file - system operations. Each request begins with an `id' field, which is - a 32-bit identifier identifying the request (selected by the client). - The same identifier will be returned in the response to the request. - One possible implementation is a monotonically increasing request - sequence number (modulo 2^32). - - Many operations in the protocol operate on open files. The - SSH_FXP_OPEN request can return a file handle (which is an opaque - variable-length string) which may be used to access the file later - (e.g. in a read operation). The client MUST NOT send requests the - server with bogus or closed handles. However, the server MUST - perform adequate checks on the handle in order to avoid security - risks due to fabricated handles. - - This design allows either stateful and stateless server - implementation, as well as an implementation which caches state - between requests but may also flush it. The contents of the file - handle string are entirely up to the server and its design. The - client should not modify or attempt to interpret the file handle - strings. - - The file handle strings MUST NOT be longer than 256 bytes. - -6.1 Request Synchronization and Reordering - - The protocol and implementations MUST process requests relating to - the same file in the order in which they are received. In other - words, if an application submits multiple requests to the server, the - results in the responses will be the same as if it had sent the - requests one at a time and waited for the response in each case. For - example, the server may process non-overlapping read/write requests - to the same file in parallel, but overlapping reads and writes cannot - be reordered or parallelized. However, there are no ordering - restrictions on the server for processing requests from two different - file transfer connections. The server may interleave and parallelize - them at will. - - There are no restrictions on the order in which responses to - outstanding requests are delivered to the client, except that the - server must ensure fairness in the sense that processing of no - request will be indefinitely delayed even if the client is sending - other requests so that there are multiple outstanding requests all - the time. - - - - - -Galbraith, et al. Expires June 18, 2003 [Page 15] - -Internet-Draft SSH File Transfer Protocol December 2002 - - -6.2 File Names - - This protocol represents file names as strings. File names are - assumed to use the slash ('/') character as a directory separator. - - File names starting with a slash are "absolute", and are relative to - the root of the file system. Names starting with any other character - are relative to the user's default directory (home directory). Note - that identifying the user is assumed to take place outside of this - protocol. - - Servers SHOULD interpret a path name component ".." as referring to - the parent directory, and "." as referring to the current directory. - If the server implementation limits access to certain parts of the - file system, it must be extra careful in parsing file names when - enforcing such restrictions. There have been numerous reported - security bugs where a ".." in a path name has allowed access outside - the intended area. - - An empty path name is valid, and it refers to the user's default - directory (usually the user's home directory). - - Otherwise, no syntax is defined for file names by this specification. - Clients should not make any other assumptions; however, they can - splice path name components returned by SSH_FXP_READDIR together - using a slash ('/') as the separator, and that will work as expected. - - In order to comply with IETF Policy on Character Sets and Languages - [2], all filenames are to be encoded in UTF-8. The shortest valid - UTF-8 encoding of the UNICODE data MUST be used. The server is - responsible for converting the UNICODE data to whatever canonical - form it requires. - - For example, if the server requires that precomposed characters - always be used, the server MUST NOT assume the filename as sent by - the client has this attribute, but must do this normalization itself. - - It is understood that the lack of well-defined semantics for file - names may cause interoperability problems between clients and servers - using radically different operating systems.

Each SSH_FXP_READDIR request returns one - - - -Galbraith, et al. Expires June 18, 2003 [Page 21] - -Internet-Draft SSH File Transfer Protocol December 2002 - - - or more file names with full file attributes for each file. The - client should call SSH_FXP_READDIR repeatedly until it has found the - file it is looking for or until the server responds with a - SSH_FXP_STATUS message indicating an error (normally SSH_FX_EOF if - there are no more files in the directory). The client should then - close the handle using the SSH_FXP_CLOSE request. - - The SSH_FXP_OPENDIR opens a directory for reading. It has the - following format: - - uint32 id - string path [UTF-8] - - where `id' is the request identifier and `path' is the path name of - the directory to be listed (without any trailing slash). See Section - ``File Names'' for more information on file names. This will return - an error if the path does not specify a directory or if the directory - is not readable. The server will respond to this request with either - a SSH_FXP_HANDLE or a SSH_FXP_STATUS message. - - Once the directory has been successfully opened, files (and - directories) contained in it can be listed using SSH_FXP_READDIR - requests. These are of the format - - uint32 id - string handle - - where `id' is the request identifier, and `handle' is a handle - returned by SSH_FXP_OPENDIR. (It is a protocol error to attempt to - use an ordinary file handle returned by SSH_FXP_OPEN.) - - The server responds to this request with either a SSH_FXP_NAME or a - SSH_FXP_STATUS message. One or more names may be returned at a time. - Full status information is returned for each name in order to speed - up typical directory listings. - - If there are no more names available to be read, the server MUST - respond with a SSH_FXP_STATUS message with error code of SSH_FX_EOF. - - When the client no longer wishes to read more names from the - directory, it SHOULD call SSH_FXP_CLOSE for the handle. The handle - should be closed regardless of whether an error has occurred or not. - -6.8 Retrieving File Attributes - - Very often, file attributes are automatically returned by - SSH_FXP_READDIR. However, sometimes there is need to specifically - retrieve the attributes for a named file. This can be done using the - - - -Galbraith, et al. Expires June 18, 2003 [Page 22] - -Internet-Draft SSH File Transfer Protocol December 2002 - - - SSH_FXP_STAT, SSH_FXP_LSTAT and SSH_FXP_FSTAT requests. - - SSH_FXP_STAT and SSH_FXP_LSTAT only differ in that SSH_FXP_STAT - follows symbolic links on the server, whereas SSH_FXP_LSTAT does not - follow symbolic links. Both have the same format: - - uint32 id - string path [UTF-8] - uint32 flags - - where `id' is the request identifier, and `path' specifies the file - system object for which status is to be returned. The server - responds to this request with either SSH_FXP_ATTRS or SSH_FXP_STATUS. - - The flags field specify the attribute flags in which the client has - particular interest. This is a hint to the server. For example, - because retrieving owner / group and acl information can be an - expensive operation under some operating systems, the server may - choose not to retrieve this information unless the client expresses a - specific interest in it. - - The client has no guarantee the server will provide all the fields - that it has expressed an interest in. - - SSH_FXP_FSTAT differs from the others in that it returns status - information for an open file (identified by the file handle). Its - format is as follows: - - uint32 id - string handle - uint32 flags - - where `id' is the request identifier and `handle' is a file handle - returned by SSH_FXP_OPEN. The server responds to this request with - SSH_FXP_ATTRS or SSH_FXP_STATUS. - -6.9 Setting File Attributes - - File attributes may be modified using the SSH_FXP_SETSTAT and - SSH_FXP_FSETSTAT requests. These requests are used for operations - such as changing the ownership, permissions or access times, as well - as for truncating a file. - - The SSH_FXP_SETSTAT request is of the following format: - - - - - - - -Galbraith, et al. Expires June 18, 2003 [Page 23] - -Internet-Draft SSH File Transfer Protocol December 2002 - - - uint32 id - string path [UTF-8] - ATTRS attrs - - where `id' is the request identifier, `path' specifies the file - system object (e.g. file or directory) whose attributes are to be - modified, and `attrs' specifies the modifications to be made to its - attributes. Attributes are discussed in more detail in Section - ``File Attributes''. - - An error will be returned if the specified file system object does - not exist or the user does not have sufficient rights to modify the - specified attributes. The server responds to this request with a - SSH_FXP_STATUS message. - - The SSH_FXP_FSETSTAT request modifies the attributes of a file which - is already open. It has the following format: - - uint32 id - string handle - ATTRS attrs - - where `id' is the request identifier, `handle' (MUST be returned by - SSH_FXP_OPEN) identifies the file whose attributes are to be - modified, and `attrs' specifies the modifications to be made to its - attributes. Attributes are discussed in more detail in Section - ``File Attributes''. The server will respond to this request with - SSH_FXP_STATUS. - -6.10 Dealing with Symbolic links - - The SSH_FXP_READLINK request may be used to read the target of a - symbolic link. It would have a data part as follows: - - uint32 id - string path [UTF-8] - - where `id' is the request identifier and `path' specifies the path - name of the symlink to be read. - - The server will respond with a SSH_FXP_NAME packet containing only - one name and a dummy attributes value. The name in the returned - packet contains the target of the link. If an error occurs, the - server may respond with SSH_FXP_STATUS. - - The SSH_FXP_SYMLINK request will create a symbolic link on the - server. It is of the following format - - - - -Galbraith, et al. Expires June 18, 2003 [Page 24] - -Internet-Draft SSH File Transfer Protocol December 2002 - - - uint32 id - string linkpath [UTF-8] - string targetpath [UTF-8] - - where `id' is the request identifier, `linkpath' specifies the path - name of the symlink to be created and `targetpath' specifies the - target of the symlink. The server shall respond with a - SSH_FXP_STATUS indicating either success (SSH_FX_OK) or an error - condition. - -6.11 Canonicalizing the Server-Side Path Name - - The SSH_FXP_REALPATH request can be used to have the server - canonicalize any given path name to an absolute path. This is useful - for converting path names containing ".." components or relative - pathnames without a leading slash into absolute paths. The format of - the request is as follows: - - uint32 id - string path [UTF-8] - - where `id' is the request identifier and `path' specifies the path - name to be canonicalized. The server will respond with a - SSH_FXP_NAME packet containing the name in canonical form and a dummy - attributes value. If an error occurs, the server may also respond - with SSH_FXP_STATUS. - -6.11.1 Best practice for dealing with paths - - The client SHOULD treat the results of SSH_FXP_REALPATH as a - canonical absolute path, even if the path does not appear to be - absolute. A client that use REALPATH(".") and treats the result as - absolute, even if there is no leading slash, will continue to - function correctly, even when talking to a Windows NT or VMS style - system, where absolute paths may not begin with a slash. - - For example, if the client wishes to change directory up, and the - server has returned "c:/x/y/z" from REALPATH, the client SHOULD use - "c:/x/y/z/..". - - As a second example, if the client wishes to open the file "x.txt" in - the current directory, and server has returned "dka100:/x/y/z" as the - canonical path of the directory, the client SHOULD open "dka100:/x/y/ - z/x.txt" - - - - - - - -Galbraith, et al. Expires June 18, 2003 [Page 25] - -Internet-Draft SSH File Transfer Protocol December 2002 - - -7. Responses from the Server to the Client - - The server responds to the client using one of a few response - packets. All requests can return a SSH_FXP_STATUS response upon - failure. When the operation is successful, any of the responses may - be returned (depending on the operation). If no data needs to be - returned to the client, the SSH_FXP_STATUS response with SSH_FX_OK - status is appropriate. Otherwise, the SSH_FXP_HANDLE message is used - to return a file handle (for SSH_FXP_OPEN and SSH_FXP_OPENDIR - requests), SSH_FXP_DATA is used to return data from SSH_FXP_READ, - SSH_FXP_NAME is used to return one or more file names from a - SSH_FXP_READDIR or SSH_FXP_REALPATH request, and SSH_FXP_ATTRS is - used to return file attributes from SSH_FXP_STAT, SSH_FXP_LSTAT, and - SSH_FXP_FSTAT requests. - - Exactly one response will be returned for each request. Each - response packet contains a request identifier which can be used to - match each response with the corresponding request. Note that it is - legal to have several requests outstanding simultaneously, and the - server is allowed to send responses to them in a different order from - the order in which the requests were sent (the result of their - execution, however, is guaranteed to be as if they had been processed - one at a time in the order in which the requests were sent). - - Response packets are of the same general format as request packets. - Each response packet begins with the request identifier. - - The format of the data portion of the SSH_FXP_STATUS response is as - follows: - - uint32 id - uint32 error/status code - string error message (ISO-10646 UTF-8 [RFC-2279]) - string language tag (as defined in [RFC-1766]) - - where `id' is the request identifier, and `error/status code' - indicates the result of the requested operation.

The - handle is opaque to the client; the client MUST NOT attempt to - interpret or modify it in any way. The length of the handle string - MUST NOT exceed 256 data bytes. - - The SSH_FXP_DATA response has the following format: - - uint32 id - string data - - where `id' is the request identifier, and `data' is an arbitrary byte - string containing the requested data.

Vendor-Specific Extensions - - The SSH_FXP_EXTENDED request provides a generic extension mechanism - for adding vendor-specific commands. The request has the following - format: - - uint32 id - string extended-request - ... any request-specific data ... - - where `id' is the request identifier, and `extended-request' is a - string of the format "name@domain", where domain is an internet - domain name of the vendor defining the request. The rest of the - request is completely vendor-specific, and servers should only - attempt to interpret it if they recognize the `extended-request' - name. - - The server may respond to such requests using any of the response - packets defined in Section ``Responses from the Server to the - Client''. Additionally, the server may also respond with a - SSH_FXP_EXTENDED_REPLY packet, as defined below. If the server does - not recognize the `extended-request' name, then the server MUST - respond with SSH_FXP_STATUS with error/status set to - SSH_FX_OP_UNSUPPORTED. - - The SSH_FXP_EXTENDED_REPLY packet can be used to carry arbitrary - extension-specific data from the server to the client. It is of the - following format: - - uint32 id - ... any request-specific data ... - - There is a range of packet types reserved for use by extensions. In - order to avoid collision, extensions that turn on the use of - additional packet types should determine those numbers dynamically. - - The suggested way of doing this is have an extension request from the - client to the server that enables the extension; the extension - response from the server to the client would specify the actual type - values to use, in additional to any other data. - - Extension authors should be mindful of the limited range of packet - types available (there are only 45 values available) and avoid - requiring a new packet type where possible. - - - - - - - -Galbraith, et al.

Contributors - - The major original contributors of this document were: Tatu Ylonen, - Tero Kivinen, Timo J. Rinne, Sami Lehtinen (all of SSH Communications - Security Corp), and Markku-Juhani O. Saarinen (University of - Jyvaskyla) - - The document editor is: [email protected]. Comments on this - internet draft should be sent to the IETF SECSH working group, - details at: http://ietf.org/html.charters/secsh-charter.html - -2. Introduction - - The SSH transport layer is a secure low level transport protocol. It - provides strong encryption, cryptographic host authentication, and - integrity protection. - - Authentication in this protocol level is host-based; this protocol - does not perform user authentication. A higher level protocol for - user authentication can be designed on top of this protocol. - - The protocol has been designed to be simple, flexible, to allow - parameter negotiation, and to minimize the number of round-trips. - Key exchange method, public key algorithm, symmetric encryption - algorithm, message authentication algorithm, and hash algorithm are - all negotiated. It is expected that in most environments, only 2 - round-trips will be needed for full key exchange, server - authentication, service request, and acceptance notification of - service request. The worst case is 3 round-trips. - -3. Conventions Used in This Document - - The keywords "MUST", "MUST NOT", "REQUIRED", "SHOULD", "SHOULD NOT", - and "MAY" that appear in this document are to be interpreted as - described in [RFC2119]. - - The used data types and terminology are specified in the architecture - document [SSH-ARCH]. - - The architecture document also discusses the algorithm naming - conventions that MUST be used with the SSH protocols. - -4. Connection Setup - - SSH works over any 8-bit clean, binary-transparent transport. The - underlying transport SHOULD protect against transmission errors as - such errors cause the SSH connection to terminate. - - - - -Ylonen & Moffat, Editor Expires March 31, 2004 [Page 3] - -Internet-Draft SSH Transport Layer Protocol Oct 2003 - - - The client initiates the connection. - -4.1 Use over TCP/IP - - When used over TCP/IP, the server normally listens for connections on - port 22. This port number has been registered with the IANA, and has - been officially assigned for SSH. - -4.2 Protocol Version Exchange - - When the connection has been established, both sides MUST send an - identification string of the form "SSH-protoversion-softwareversion - comments", followed by carriage return and newline characters (ASCII - 13 and 10, respectively). Both sides MUST be able to process - identification strings without carriage return character. No null - character is sent. The maximum length of the string is 255 - characters, including the carriage return and newline. - - The part of the identification string preceding carriage return and - newline is used in the Diffie-Hellman key exchange (see Section - Section 7). - - The server MAY send other lines of data before sending the version - string. Each line SHOULD be terminated by a carriage return and - newline. Such lines MUST NOT begin with "SSH-", and SHOULD be - encoded in ISO-10646 UTF-8 [RFC2279] (language is not specified). - Clients MUST be able to process such lines; they MAY be silently - ignored, or MAY be displayed to the client user; if they are - displayed, control character filtering discussed in [SSH-ARCH] SHOULD - be used. The primary use of this feature is to allow TCP-wrappers to - display an error message before disconnecting. - - Version strings MUST consist of printable US-ASCII characters, not - including whitespaces or a minus sign (-). The version string is - primarily used to trigger compatibility extensions and to indicate - the capabilities of an implementation. The comment string should - contain additional information that might be useful in solving user - problems. - - The protocol version described in this document is 2.0. - - Key exchange will begin immediately after sending this identifier. - All packets following the identification string SHALL use the binary - packet protocol, to be described below. - -4.3 Compatibility With Old SSH Versions - - During the transition period, it is important to be able to work in a - - - -Ylonen & Moffat, Editor Expires March 31, 2004 [Page 4] - -Internet-Draft SSH Transport Layer Protocol Oct 2003 - - - way that is compatible with the installed SSH clients and servers - that use an older version of the protocol. Information in this - section is only relevant for implementations supporting compatibility - with SSH versions 1.x. There is no standards track or informational - draft available that defines the SSH 1.x protocol. The only known - documentation of the 1.x protocol is contained in README files that - are shipped along with the source code. - -4.3.1 Old Client, New Server - - Server implementations MAY support a configurable "compatibility" - flag that enables compatibility with old versions. When this flag is - on, the server SHOULD identify its protocol version as "1.99". - Clients using protocol 2.0 MUST be able to identify this as identical - to "2.0". In this mode the server SHOULD NOT send the carriage - return character (ASCII 13) after the version identification string. - - In the compatibility mode the server SHOULD NOT send any further data - after its initialization string until it has received an - identification string from the client. The server can then determine - whether the client is using an old protocol, and can revert to the - old protocol if required. In the compatibility mode, the server MUST - NOT send additional data before the version string. - - When compatibility with old clients is not needed, the server MAY - send its initial key exchange data immediately after the - identification string. - -4.3.2 New Client, Old Server - - Since the new client MAY immediately send additional data after its - identification string (before receiving server's identification), the - old protocol may already have been corrupted when the client learns - that the server is old. When this happens, the client SHOULD close - the connection to the server, and reconnect using the old protocol. - -5. Binary Packet Protocol - - Each packet is in the following format: - - uint32 packet_length - byte padding_length - byte[n1] payload; n1 = packet_length - padding_length - 1 - byte[n2] random padding; n2 = padding_length - byte[m] mac (message authentication code); m = mac_length - - packet_length - - - - -Ylonen & Moffat, Editor Expires March 31, 2004 [Page 5] - -Internet-Draft SSH Transport Layer Protocol Oct 2003 - - - The length of the packet (bytes), not including MAC or the - packet_length field itself. - - padding_length - Length of padding (bytes). - - payload - The useful contents of the packet. If compression has been - negotiated, this field is compressed. Initially, compression - MUST be "none". - - random padding - Arbitrary-length padding, such that the total length of - (packet_length || padding_length || payload || padding) is a - multiple of the cipher block size or 8, whichever is larger. - There MUST be at least four bytes of padding. The padding - SHOULD consist of random bytes. The maximum amount of padding - is 255 bytes. - - mac - Message authentication code. If message authentication has - been negotiated, this field contains the MAC bytes. Initially, - the MAC algorithm MUST be "none". - - - Note that length of the concatenation of packet length, padding - length, payload, and padding MUST be a multiple of the cipher block - size or 8, whichever is larger. This constraint MUST be enforced - even when using stream ciphers. Note that the packet length field is - also encrypted, and processing it requires special care when sending - or receiving packets. - - The minimum size of a packet is 16 (or the cipher block size, - whichever is larger) bytes (plus MAC); implementations SHOULD decrypt - the length after receiving the first 8 (or cipher block size, - whichever is larger) bytes of a packet. - -5.1 Maximum Packet Length - - All implementations MUST be able to process packets with uncompressed - payload length of 32768 bytes or less and total packet size of 35000 - bytes or less (including length, padding length, payload, padding, - and MAC.). The maximum of 35000 bytes is an arbitrary chosen value - larger than uncompressed size. Implementations SHOULD support longer - packets, where they might be needed, e.g. if an implementation wants - to send a very large number of certificates. Such packets MAY be - sent if the version string indicates that the other party is able to - process them. However, implementations SHOULD check that the packet - - - -Ylonen & Moffat, Editor Expires March 31, 2004 [Page 6] - -Internet-Draft SSH Transport Layer Protocol Oct 2003 - - - length is reasonable for the implementation to avoid - denial-of-service and/or buffer overflow attacks. - -5.2 Compression - - If compression has been negotiated, the payload field (and only it) - will be compressed using the negotiated algorithm. The length field - and MAC will be computed from the compressed payload. Encryption will - be done after compression. - - Compression MAY be stateful, depending on the method. Compression - MUST be independent for each direction, and implementations MUST - allow independently choosing the algorithm for each direction. - - The following compression methods are currently defined: - - none REQUIRED no compression - zlib OPTIONAL ZLIB (LZ77) compression - - The "zlib" compression is described in [RFC1950] and in [RFC1951]. - The compression context is initialized after each key exchange, and - is passed from one packet to the next with only a partial flush being - performed at the end of each packet. A partial flush means that the - current compressed block is ended and all data will be output. If the - current block is not a stored block, one or more empty blocks are - added after the current block to ensure that there are at least 8 - bits counting from the start of the end-of-block code of the current - block to the end of the packet payload. - - Additional methods may be defined as specified in [SSH-ARCH]. - -5.3 Encryption - - An encryption algorithm and a key will be negotiated during the key - exchange.

This document freely uses terminology and - notation from the architecture document without reference or further - explanation. - - The service name for this protocol is "ssh-userauth". - - When this protocol starts, it receives the session identifier from - the lower-level protocol (this is the exchange hash H from the first - key exchange). The session identifier uniquely identifies this - session and is suitable for signing in order to prove ownership of a - private key. This protocol also needs to know whether the lower-level - protocol provides confidentiality protection. - -3. Conventions Used in This Document - - The keywords "MUST", "MUST NOT", "REQUIRED", "SHOULD", "SHOULD NOT", - and "MAY" that appear in this document are to be interpreted as - described in [RFC2119] - - The used data types and terminology are specified in the architecture - document [SSH-ARCH] - - The architecture document also discusses the algorithm naming - conventions that MUST be used with the SSH protocols. - -3.1 The Authentication Protocol Framework - - The server drives the authentication by telling the client which - - - -Ylonen & Moffat Expires March 2, 2003 [Page 3] - -Internet-Draft SSH Authentication Protocol September 2002 - - - authentication methods can be used to continue the exchange at any - given time. The client has the freedom to try the methods listed by - the server in any order. This gives the server complete control over - the authentication process if desired, but also gives enough - flexibility for the client to use the methods it supports or that are - most convenient for the user, when multiple methods are offered by - the server. - - Authentication methods are identified by their name, as defined in - [SSH-ARCH]. The "none" method is reserved, and MUST NOT be listed as - supported. However, it MAY be sent by the client. The server MUST - always reject this request, unless the client is to be allowed in - without any authentication, in which case the server MUST accept this - request. The main purpose of sending this request is to get the list - of supported methods from the server. - - The server SHOULD have a timeout for authentication, and disconnect - if the authentication has not been accepted within the timeout - period. The RECOMMENDED timeout period is 10 minutes. Additionally, - the implementation SHOULD limit the number of failed authentication - attempts a client may perform in a single session (the RECOMMENDED - limit is 20 attempts). If the threshold is exceeded, the server - SHOULD disconnect. - -3.1.1 Authentication Requests - - All authentication requests MUST use the following message format. - Only the first few fields are defined; the remaining fields depend on - the authentication method. - - byte SSH_MSG_USERAUTH_REQUEST - string user name (in ISO-10646 UTF-8 encoding [RFC2279]) - string service name (in US-ASCII) - string method name (US-ASCII) - The rest of the packet is method-specific. - - The user name and service are repeated in every new authentication - attempt, and MAY change. The server implementation MUST carefully - check them in every message, and MUST flush any accumulated - authentication states if they change. If it is unable to flush some - authentication state, it MUST disconnect if the user or service name - changes. - - The service name specifies the service to start after authentication. - There may be several different authenticated services provided. If - the requested service is not available, the server MAY disconnect - immediately or at any later time. Sending a proper disconnect - message is RECOMMENDED. In any case, if the service does not exist, - - - -Ylonen & Moffat Expires March 2, 2003 [Page 4] - -Internet-Draft SSH Authentication Protocol September 2002 - - - authentication MUST NOT be accepted. - - If the requested user does not exist, the server MAY disconnect, or - MAY send a bogus list of acceptable authentication methods, but never - accept any. This makes it possible for the server to avoid - disclosing information on which accounts exist. In any case, if the - user does not exist, the authentication request MUST NOT be accepted. - - While there is usually little point for clients to send requests that - the server does not list as acceptable, sending such requests is not - an error, and the server SHOULD simply reject requests that it does - not recognize. - - An authentication request MAY result in a further exchange of - messages. All such messages depend on the authentication method - used, and the client MAY at any time continue with a new - SSH_MSG_USERAUTH_REQUEST message, in which case the server MUST - abandon the previous authentication attempt and continue with the new - one. - -3.1.2 Responses to Authentication Requests - - If the server rejects the authentication request, it MUST respond - with the following: - - byte SSH_MSG_USERAUTH_FAILURE - string authentications that can continue - boolean partial success - - "Authentications that can continue" is a comma-separated list of - authentication method names that may productively continue the - authentication dialog. - - It is RECOMMENDED that servers only include those methods in the list - that are actually useful. However, it is not illegal to include - methods that cannot be used to authenticate the user. - - Already successfully completed authentications SHOULD NOT be included - in the list, unless they really should be performed again for some - reason. - - "Partial success" MUST be TRUE if the authentication request to which - this is a response was successful. It MUST be FALSE if the request - was not successfully processed. - - When the server accepts authentication, it MUST respond with the - following: - - - - -Ylonen & Moffat Expires March 2, 2003 [Page 5] - -Internet-Draft SSH Authentication Protocol September 2002 - - - byte SSH_MSG_USERAUTH_SUCCESS - - Note that this is not sent after each step in a multi-method - authentication sequence, but only when the authentication is - complete. - - The client MAY send several authentication requests without waiting - for responses from previous requests. The server MUST process each - request completely and acknowledge any failed requests with a - SSH_MSG_USERAUTH_FAILURE message before processing the next request. - - A request that results in further exchange of messages will be - aborted by a second request. It is not possible to send a second - request without waiting for a response from the server, if the first - request will result in further exchange of messages. No - SSH_MSG_USERAUTH_FAILURE message will be sent for the aborted method. - - SSH_MSG_USERAUTH_SUCCESS MUST be sent only once. When - SSH_MSG_USERAUTH_SUCCESS has been sent, any further authentication - requests received after that SHOULD be silently ignored. - - Any non-authentication messages sent by the client after the request - that resulted in SSH_MSG_USERAUTH_SUCCESS being sent MUST be passed - to the service being run on top of this protocol. Such messages can - be identified by their message numbers (see Section Message Numbers - (Section 3.2)). - -3.1.3 The "none" Authentication Request - - A client may request a list of authentication methods that may - continue by using the "none" authentication method. - - If no authentication at all is needed for the user, the server MUST - return SSH_MSG_USERAUTH_SUCCESS. Otherwise, the server MUST return - SSH_MSG_USERAUTH_FAILURE and MAY return with it a list of - authentication methods that can continue. - - This method MUST NOT be listed as supported by the server. - -3.1.4 Completion of User Authentication - - Authentication is complete when the server has responded with - SSH_MSG_USERAUTH_SUCCESS; all authentication related messages - received after sending this message SHOULD be silently ignored. - - After sending SSH_MSG_USERAUTH_SUCCESS, the server starts the - requested service. - - - - -Ylonen & Moffat Expires March 2, 2003 [Page 6] - -Internet-Draft SSH Authentication Protocol September 2002 - - -3.1.5 Banner Message - - In some jurisdictions, sending a warning message before - authentication may be relevant for getting legal protection. Many - UNIX machines, for example, normally display text from `/etc/issue', - or use "tcp wrappers" or similar software to display a banner before - issuing a login prompt. - - The SSH server may send a SSH_MSG_USERAUTH_BANNER message at any time - before authentication is successful. This message contains text to - be displayed to the client user before authentication is attempted. - The format is as follows: - - byte SSH_MSG_USERAUTH_BANNER - string message (ISO-10646 UTF-8) - string language tag (as defined in [RFC3066]) - - The client SHOULD by default display the message on the screen. - However, since the message is likely to be sent for every login - attempt, and since some client software will need to open a separate - window for this warning, the client software may allow the user to - explicitly disable the display of banners from the server. The - message may consist of multiple lines. - - If the message string is displayed, control character filtering - discussed in [SSH-ARCH] SHOULD be used to avoid attacks by sending - terminal control characters. - -3.2 Authentication Protocol Message Numbers - - All message numbers used by this authentication protocol are in the - range from 50 to 79, which is part of the range reserved for - protocols running on top of the SSH transport layer protocol. - - Message numbers of 80 and higher are reserved for protocols running - after this authentication protocol, so receiving one of them before - authentication is complete is an error, to which the server MUST - respond by disconnecting (preferably with a proper disconnect message - sent first to ease troubleshooting). - - After successful authentication, such messages are passed to the - higher-level service. - - These are the general authentication message codes: - - #define SSH_MSG_USERAUTH_REQUEST 50 - #define SSH_MSG_USERAUTH_FAILURE 51 - #define SSH_MSG_USERAUTH_SUCCESS 52 - - - -Ylonen & Moffat Expires March 2, 2003 [Page 7] - -Internet-Draft SSH Authentication Protocol September 2002 - - - #define SSH_MSG_USERAUTH_BANNER 53 - - In addition to the above, there is a range of message numbers - (60..79) reserved for method-specific messages. These messages are - only sent by the server (client sends only SSH_MSG_USERAUTH_REQUEST - messages). Different authentication methods reuse the same message - numbers. - -3.3 Public Key Authentication Method: publickey - - The only REQUIRED authentication method is public key authentication. - All implementations MUST support this method; however, not all users - need to have public keys, and most local policies are not likely to - require public key authentication for all users in the near future. - - With this method, the possession of a private key serves as - authentication. This method works by sending a signature created - with a private key of the user. The server MUST check that the key - is a valid authenticator for the user, and MUST check that the - signature is valid. If both hold, the authentication request MUST be - accepted; otherwise it MUST be rejected. (Note that the server MAY - require additional authentications after successful authentication.) - - Private keys are often stored in an encrypted form at the client - host, and the user must supply a passphrase before the signature can - be generated. Even if they are not, the signing operation involves - some expensive computation. To avoid unnecessary processing and user - interaction, the following message is provided for querying whether - authentication using the key would be acceptable. - - byte SSH_MSG_USERAUTH_REQUEST - string user name - string service - string "publickey" - boolean FALSE - string public key algorithm name - string public key blob - - Public key algorithms are defined in the transport layer - specification [SSH-TRANS]. The public key blob may contain - certificates. - - Any public key algorithm may be offered for use in authentication. - In particular, the list is not constrained by what was negotiated - during key exchange. If the server does not support some algorithm, - it MUST simply reject the request. - - The server MUST respond to this message with either - - - -Ylonen & Moffat Expires March 2, 2003 [Page 8] - -Internet-Draft SSH Authentication Protocol September 2002 - - - SSH_MSG_USERAUTH_FAILURE or with the following: - - byte SSH_MSG_USERAUTH_PK_OK - string public key algorithm name from the request - string public key blob from the request - - To perform actual authentication, the client MAY then send a - signature generated using the private key. The client MAY send the - signature directly without first verifying whether the key is - acceptable. The signature is sent using the following packet: - - byte SSH_MSG_USERAUTH_REQUEST - string user name - string service - string "publickey" - boolean TRUE - string public key algorithm name - string public key to be used for authentication - string signature - - Signature is a signature by the corresponding private key over the - following data, in the following order: - - string session identifier - byte SSH_MSG_USERAUTH_REQUEST - string user name - string service - string "publickey" - boolean TRUE - string public key algorithm name - string public key to be used for authentication - - When the server receives this message, it MUST check whether the - supplied key is acceptable for authentication, and if so, it MUST - check whether the signature is correct. - - If both checks succeed, this method is successful. Note that the - server may require additional authentications. The server MUST - respond with SSH_MSG_USERAUTH_SUCCESS (if no more authentications are - needed), or SSH_MSG_USERAUTH_FAILURE (if the request failed, or more - authentications are needed). - - The following method-specific message numbers are used by the - publickey authentication method. - - /* Key-based */ - #define SSH_MSG_USERAUTH_PK_OK 60 - - - - -Ylonen & Moffat Expires March 2, 2003 [Page 9] - -Internet-Draft SSH Authentication Protocol September 2002 - - -3.4 Password Authentication Method: password - - Password authentication uses the following packets. Note that a - server MAY request the user to change the password. All - implementations SHOULD support password authentication. - - byte SSH_MSG_USERAUTH_REQUEST - string user name - string service - string "password" - boolean FALSE - string plaintext password (ISO-10646 UTF-8) - - Note that the password is encoded in ISO-10646 UTF-8. It is up to - the server how it interprets the password and validates it against - the password database. However, if the client reads the password in - some other encoding (e.g., ISO 8859-1 (ISO Latin1)), it MUST convert - the password to ISO-10646 UTF-8 before transmitting, and the server - MUST convert the password to the encoding used on that system for - passwords. - - Note that even though the cleartext password is transmitted in the - packet, the entire packet is encrypted by the transport layer. Both - the server and the client should check whether the underlying - transport layer provides confidentiality (i.e., if encryption is - being used). If no confidentiality is provided (none cipher), - password authentication SHOULD be disabled. If there is no - confidentiality or no MAC, password change SHOULD be disabled. - - Normally, the server responds to this message with success or - failure. However, if the password has expired the server SHOULD - indicate this by responding with SSH_MSG_USERAUTH_PASSWD_CHANGEREQ. - In anycase the server MUST NOT allow an expired password to be used - for authentication. - - byte SSH_MSG_USERAUTH_PASSWD_CHANGEREQ - string prompt (ISO-10646 UTF-8) - string language tag (as defined in [RFC3066]) - - In this case, the client MAY continue with a different authentication - method, or request a new password from the user and retry password - authentication using the following message. The client MAY also send - this message instead of the normal password authentication request - without the server asking for it. - - byte SSH_MSG_USERAUTH_REQUEST - string user name - string service - - - -Ylonen & Moffat Expires March 2, 2003 [Page 10] - -Internet-Draft SSH Authentication Protocol September 2002 - - - string "password" - boolean TRUE - string plaintext old password (ISO-10646 UTF-8) - string plaintext new password (ISO-10646 UTF-8) - - The server must reply to request message with - SSH_MSG_USERAUTH_SUCCESS, SSH_MSG_USERAUTH_FAILURE, or another - SSH_MSG_USERAUTH_PASSWD_CHANGEREQ. The meaning of these is as - follows: - - SSH_MSG_USERAUTH_SUCCESS The password has been changed, and - authentication has been successfully completed. - - SSH_MSG_USERAUTH_FAILURE with partial success The password has - been changed, but more authentications are needed. - - SSH_MSG_USERAUTH_FAILURE without partial success The password has - not been changed. Either password changing was not supported, or - the old password was bad. Note that if the server has already - sent SSH_MSG_USERAUTH_PASSWD_CHANGEREQ, we know that it supports - changing the password. - - SSH_MSG_USERAUTH_CHANGEREQ The password was not changed because - the new password was not acceptable (e.g. too easy to guess). - - The following method-specific message numbers are used by the - password authentication method. - - #define SSH_MSG_USERAUTH_PASSWD_CHANGEREQ 60 - - -3.5 Host-Based Authentication: hostbased - - Some sites wish to allow authentication based on the host where the - user is coming from, and the user name on the remote host. While - this form of authentication is not suitable for high-security sites, - it can be very convenient in many environments. This form of - authentication is OPTIONAL. When used, special care SHOULD be taken - to prevent a regular user from obtaining the private host key. - - The client requests this form of authentication by sending the - following message. It is similar to the UNIX "rhosts" and - "hosts.equiv" styles of authentication, except that the identity of - the client host is checked more rigorously. - - This method works by having the client send a signature created with - the private key of the client host, which the server checks with that - host's public key. Once the client host's identity is established, - - - -Ylonen & Moffat Expires March 2, 2003 [Page 11] - -Internet-Draft SSH Authentication Protocol September 2002 - - - authorization (but no further authentication) is performed based on - the user names on the server and the client, and the client host - name. - - byte SSH_MSG_USERAUTH_REQUEST - string user name - string service - string "hostbased" - string public key algorithm for host key - string public host key and certificates for client host - string client host name (FQDN; US-ASCII) - string user name on the client host (ISO-10646 UTF-8) - string signature - - Public key algorithm names for use in "public key algorithm for host - key" are defined in the transport layer specification. The "public - host key for client host" may include certificates. - - Signature is a signature with the private host key of the following - data, in this order: - - string session identifier - byte SSH_MSG_USERAUTH_REQUEST - string user name - string service - string "hostbased" - string public key algorithm for host key - string public host key and certificates for client host - string client host name (FQDN; US-ASCII) - string user name on the client host(ISO-10646 UTF-8) - - The server MUST verify that the host key actually belongs to the - client host named in the message, that the given user on that host is - allowed to log in, and that the signature is a valid signature on the - appropriate value by the given host key. The server MAY ignore the - client user name, if it wants to authenticate only the client host. - - It is RECOMMENDED that whenever possible, the server perform - additional checks to verify that the network address obtained from - the (untrusted) network matches the given client host name. This - makes exploiting compromised host keys more difficult. Note that - this may require special handling for connections coming through a - firewall. - -4.
