+ <title>Purpose</title>
+
+ <p>Secure Shell (SSH) is a protocol for secure remote login and
+ other secure network services over an insecure network. SSH
+ provides a single, full-duplex, byte-oriented connection between
+ client and server. The protocol also provides privacy, integrity,
+ server authentication and man-in-the-middle protection.</p>
+
+ <p>The Erlang SSH application is an implementation of the SSH
+ protocol in Erlang which offers API functions to write customized
+ SSH clients and servers as well as making the Erlang shell
+ available via SSH. Also included in the SSH application are an
+ SFTP (SSH File Transfer Protocol) client <seealso
+ marker="ssh_sftp">ssh_sftp</seealso> and server <seealso
+ marker="ssh_sftp">ssh_sftpd</seealso>.</p>
+ </section>
+
+ <section>
+ <title>Prerequisites</title>
+ <p>It is assumed that the reader is familiar with the concepts of <seealso marker="doc/design_principles:des_princ">OTP</seealso>
+ and has a basic understanding of <url href="http://en.wikipedia.org/wiki/Public-key_cryptography">public keys</url>.</p>

- <p>Ssh services are implemented as channels that are multiplexed
- over an ssh connection and communicates via the ssh connection
- protocol. This module provides a callback API that takes care of
- generic channel aspects such as flow control and close messages
- and lets the callback functions take care of the service specific
- parts.
+ <p>SSH services (clients and servers) are implemented as channels
+ that are multiplexed over an SSH connection and communicates via
+ the <url href="http://www.ietf.org/rfc/rfc4254.txt"> SSH
+ Connection Protocol</url>. This module provides a callback API
+ that takes care of generic channel aspects such as flow control
+ and close messages and lets the callback functions take care of
+ the service (application) specific parts. This behavior also ensures
+ that the channel process honors the principal of an OTP-process so
+ that it can be part of a supervisor tree. This is a requirement of
+ channel processes implementing a subsystem that will be added to
+ the SSH applications supervisor tree.
</p>
+
+ <note> <p>When implementing a SSH subsystem use the
+ <c>-behaviour(ssh_daemon_channel).</c> instead of <c>-behaviour(ssh_channel).</c>
+ as the only relevant callback functions for subsystems are
+ init/1, handle_ssh_msg/2, handle_msg/2 and terminate/2, so the ssh_daemon_channel
+ behaviour is limited version of the ssh_channel behaviour.

+ that are received as messages by the remote channel.
+ In the case that the receiving channel is an Erlang process the
+ message will be on the following format
+ <c><![CDATA[{ssh_cm, ssh_connection_ref(), ssh_event_msg()}]]></c>. If the <seealso

+ <title>SSH Protocol Overview</title>
+
+ <p> Conceptually the SSH protocol can be partitioned into four
+ layers:</p>
+
+ <image file="SSH_protocols.png">
+ <icaption>SSH Protocol Architecture</icaption>
+ </image>
+
+ <section>
+ <title>Transport Protocol</title>
+
+ <p> The SSH Transport Protocol is a secure, low level transport.
+ It provides strong encryption, cryptographic host
+ authentication and integrity protection. Currently, only a
+ minimum of MAC- (message authentication code, a short piece of
+ information used to authenticate a message) and encryption
+ algorithms are supported see <seealso marker="ssh">ssh(3)</seealso>
+ </p>
+ </section>
+
+ <section>
+ <title>Authentication Protocol</title>
+
+ <p>The SSH authentication protocol is a general-purpose user
+ authentication protocol run over the SSH transport
+ protocol. Erlang SSH supports user authentication using public
+ key technology (RSA and DSA, X509-certificates are currently not
+ supported). It is also possible to use a so called keyboard
+ interactive authentication. This method is suitable for
+ interactive authentication methods that do not need any special
+ software support on the client side. Instead, all authentication
+ data should be entered via the keyboard. It is also possible
+ to use a pure password based authentication scheme, note that in
+ this case the the plain text password will be encrypted before sent
+ over the network. There are several configuration options for
+ authentication handling available in
+ <seealso marker="ssh#connect-3">ssh:connect/[3,4]</seealso>
+ and <seealso marker="ssh#daemon-2">ssh:daemon/[2,3]</seealso>
+ It is also possible to customize the public key handling
+ by implementing the behaviours <seealso
+ marker="ssh_client_key_api">ssh_client_key_api</seealso> and
+ <seealso
+ marker="ssh_server_key_api">ssh_server_key_api</seealso>
+ </p>
+ </section>
+
+ <section>
+ <title>Connection Protocol</title>
+
+ <p>The SSH Connection Protocol provides application-support
+ services over the transport pipe, such as channel multiplexing,
+ flow control, remote program execution, signal propagation,
+ connection forwarding, etc. Functions for handling the SSH
+ Connection Protocol can be found in the module <seealso
+ marker="ssh_connection">ssh_connection</seealso>.
+ </p>
+ </section>
+
+ <section>
+ <title>Channels</title>
+
+ <p>All terminal sessions, forwarded connections etc., are
+ channels. Multiple channels are multiplexed into a single
+ connection, and all channels are flow-controlled. Typically an
+ SSH client will open a channel, send data/commands, receive
+ data/"control information" and when it is done close the
+ channel. The <seealso
+ marker="ssh_channel">ssh_channel</seealso> behaviour makes it easy to
+ write your own SSH client/server processes that use flow
+ control. It handles generic parts of SSH channel management and
+ lets you focus on the application logic.
+ </p>
+
+ <p>Channels comes in three flavors</p>
+
+ <list type="bulleted">
+ <item><em>Subsystem</em> - named services that can be run as
+ part of an SSH server such as SFTP <seealso
+ marker="ssh_sftpd">ssh_sftpd</seealso>, that is built in to the
+ SSH daemon (server) by default but may be disabled. The Erlang SSH
+ daemon may be configured to run any Erlang
+ implemented SSH subsystem.
+ </item>
+ <item><em>Shell</em> - interactive shell. By default the
+ Erlang daemon will run the Erlang shell. It is
+ possible to customize the shell by providing your own
+ read-eval-print loop. It is also possible, but much more work,
+ to provide your own CLI (Command Line Interface) implementation.
+ </item>
+ <item><em>Exec</em> - one-time remote execution of commands. See <seealso
+ marker="ssh_connection#exec-4">ssh_connection:exec/4</seealso></item>
+ </list>
+ </section>
+
+ <p>Channels are flow controlled. No data may be sent to a channel
+ peer until a message is received to indicate that window space is
+ available. The 'initial window size' specifies how many bytes of
+ channel data that can be sent to the channel peer without adjusting the
+ window.
+ </p>

+ following RFCs:

+ <section>
+ <title> General information</title>
+ <p>The examples in the following sections use the utility function
+ <seealso marker="ssh#start-0"> ssh:start/0 </seealso> that starts
+ all needed applications (crypto, public_key and ssh). All examples
+ are run in an Erlang shell, or in a bash shell using openssh to
+ illustrate how the erlang ssh application can be used. The
+ exampels are run as the user otptest on a local network where the
+ user is authorized to login in over ssh to the host "tarlop". If
+ nothing else is stated it is persumed that the otptest user has an
+ entry in tarlop's authorized_keys file (may log in via ssh without
+ entering a password). Also tarlop is a known host in the user
+ otptest's known_hosts file so that host verification can be done
+ without user interaction.
+ </p>
+ </section>
+
+ <section>
+ <title>Using the Erlang SSH Terminal Client</title>
+
+ <p>The user otptest, that has bash as default shell, uses the
+ ssh:shell/1 client to connect to the openssh daemon running on a
+ host called tarlop. Note that currently this client is very simple
+ and you should not be expected to be as fancy as the openssh
+ client.</p>
+

+ 1> ssh:start().
+ ok
+ 2> {ok, S} = ssh:shell("tarlop").
+ >pwd

+ >exit
+ logout

+ </section>
+
+ <section>
+ <title>Running an Erlang SSH Daemon </title>
+
+ <p> The option system_dir must be a directory containing a host
+ key file and it defaults to /etc/ssh. For details see section
+ Configuration Files in <seealso
+ marker="SSH_app">ssh(6)</seealso>.
+ </p>
+
+ <note><p>Normally the /etc/ssh directory is only readable by root. </p>
+ </note>
+
+ <p> The option user_dir defaults to the users ~/.ssh directory</p>
+
+ <p>In the following example we generate new keys and host keys as
+ to be able to run the example without having root privilages</p>
+
+ <code>

+ [...]
+ $bash> ssh-keygen -t rsa -f /tmp/otptest_user/.ssh/id_rsa

+ </code>
+
+ <p>Use the openssh client from a shell to connect to the Erlang ssh daemon.</p>
+
+ <code>
+ $bash> ssh tarlop -p 8989 -i /tmp/otptest_user/.ssh/id_rsa\
