+ <description>
+ <p>This module is the default callback handler for the client's and the server's user and host "database" operations.
+ All data, for instance key pairs, are stored in files in the normal file system. This page documents the files, where they
+ are stored and configuration options for this callback module.
+ </p>
+ <p>The intention is to be compatible with the
+ <url href="http://www.openssh.com">OpenSSH</url>
+ storage in files. Therefore it mimics directories and filenames of
+ <url href="http://www.openssh.com">OpenSSH</url>.
+ </p>
+
+ <p>Ssh_file implements the <seealso marker="ssh:ssh_server_key_api">ssh_server_key_api</seealso> and
+ the <seealso marker="ssh:ssh_client_key_api">ssh_client_key_api</seealso>.
+ This enables the user to make an own interface using for example a database handler.
+ </p>
+ <p>Such another callback module could be used by setting the option
+ <seealso marker="ssh:ssh#type-key_cb_common_option"><c>key_cb</c></seealso>
+ when starting a client or a server (with for example
+ <seealso marker="ssh:ssh#connect-3">ssh:connect</seealso>,
+ <seealso marker="ssh:ssh#daemon-2">ssh:daemon</seealso> of
+ <seealso marker="ssh:ssh#shell-1">ssh:shell</seealso>
+ ).
+ </p>
+

+ <p>In the following terms that may cause confusion are explained.
+ </p>
+ </section>
+
+ <section>
+ <title>The term "user"</title>
+ <p>A "user" is a term that everyone understands intuitively. However, the understandings may differ which can
+ cause confusion.
+ </p>
+ <p>The term is used differently in <url href="http://www.openssh.com">OpenSSH</url> and SSH in Erlang/OTP.
+ The reason is the different environments and use cases that are not immediatly obvious.
+ </p>
+ <p>This chapter aims at explaining the differences and giving a rationale for why Erlang/OTP handles "user" as
+ it does.
+ </p>
+
+ <section>
+ <title>In OpenSSH</title>
+ <p>Many have been in contact with the command 'ssh' on a Linux machine (or similar) to remotly log in on
+ another machine. One types
+ </p>
+ <code>ssh host</code>
+ <p>to log in on the machine named <c>host</c>. The command prompts for your password on the remote <c>host</c> and
+ then you can read, write and execute as your <i>user name</i> has rights on the remote <c>host</c>. There are
+ stronger variants with pre-distributed keys or certificates, but that are for now just details in the
+ authentication process.
+ </p>
+ <p>You could log in as the user <c>anotheruser</c> with
+ </p>
+ <code>ssh anotheruser@host</code>
+ <p>and you will then be enabled to act as <c>anotheruser</c> on the <c>host</c> if authorized correctly.
+ </p>
+ <p>So what does <i>"your user name has rights"</i> mean? In a UNIX/Linux/etc context it is exactly as that context:
+ The <i>user</i> could read, write and execute programs according to the OS rules.
+ In addition, the user has a home directory (<c>$HOME</c>) and there is a <c>$HOME/.ssh/</c> directory
+ with ssh-specific files.
+ </p>
+ <section>
+ <title>SSH password authentication</title>
+ <p>When SSH tries to log in to a host, the ssh protocol communicates the user name (as a string) and a password.
+ The remote ssh server checks that there is such a user defined and that the provided password is acceptable.
+ </p>
+ <p>If so, the user is authorized.
+ </p>
+ </section>
+ <section>
+ <title>SSH public key authentication</title>
+ <p>This is a stronger method where the ssh protocol brings the user name, the user's public key and some
+ cryptographic information which we could ignore here.
+ </p>
+ <p>The ssh server on the remote host checks:
+ </p>
+ <list>
+ <item>That the <i>user</i> has a home directory,</item>
+ <item>that home directory contains a .ssh/ directory and</item>
+ <item>the .ssh/ directory contains the public key just received in the <c>authorized_keys</c> file</item>
+ </list>
+ <p>if so, the user is authorized.
+ </p>
+ </section>
+ <section>
+ <title>The SSH server on UNIX/Linux/etc after a succesful authentication</title>
+ <p>After a succesful incoming authentication, a new process runs as the just authenticated user.</p>
+ <p>Next step is to start a service according to the ssh request. In case of a request of a shell,
+ a new one is started which handles the OS-commands that arrives from the client (that's "you").
+ </p>
+ <p>In case of a sftp request, an sftp server is started in with the user's rights. So it could read, write or delete
+ files if allowed for that user.
+ </p>
+ </section>
+ </section>
+
+ <section>
+ <title>In Erlang/OTP SSH</title>
+ <p>For the Erlang/OTP SSH server the situation is different. The server executes in an Erlang process
+ in the Erlang emulator which in turn executes in an OS process. The emulator does not try to change its
+ user when authenticated over the SSH protocol.
+ So the remote user name is only for authentication purposes in the Erlang/OTP SSH application.
+ </p>
+ <section>
+ <title>Password authentication in Erlang SSH</title>
+ <p>The Erlang/OTP SSH server checks the user name and password in the following order:
+ </p>
+ <list type="ordered">
+ <item>If a
+ <seealso marker="ssh:ssh#option-pwdfun"><c>pwdfun</c></seealso>
+ is defined, that one is called and the returned boolean is the authentication result.
+ </item>
+ <item>Else, if the
+ <seealso marker="ssh:ssh#option-user_passwords"><c>user_passwords</c></seealso>
+ option is defined and the username and the password matches, the authentication is a success.
+ </item>
+ <item>Else, if the option
+ <seealso marker="ssh:ssh#option-password"><c>password</c></seealso>
+ is defined and matches the password the authentication is a success.
+ Note that the use of this option is not recommended in non-test code.
+ </item>
+ </list>
+ </section>
+ <section>
+ <title>Public key authentication in Erlang SSH</title>
+ <p>The user name, public key and cryptographic data (a signature) that is sent by the client, are used as follows
+ (some steps left out for clearity):
+ </p>
+ <list type="ordered">
+ <item>A callback module is selected using the options
+ <seealso marker="ssh:ssh#type-key_cb_common_option"><c>key_cb</c></seealso>.
+ </item>
+ <item>The callback module is used to check that the provided public key is one of the user's pre-stored.
+ In case of the default callback module, the files <c>authorized_keys</c> and <c>authorized_keys2</c>
+ are searched in a directory found in the following order:
+ <list>
+ <item>If the option
+ <seealso marker="ssh:ssh_file#type-user_dir_fun_common_option"><c>user_dir_fun</c></seealso>
+ is defined, that fun is called and the returned directory is used,
+ </item>
+ <item>Else, If the option
+ <seealso marker="ssh:ssh_file#type-user_dir_common_option"><c>user_dir</c></seealso>
+ is defined, that directory is used,
+ </item>
+ <item>Else the subdirectory <c>.ssh</c> in the home directory of the user executing
+ the OS process of the Erlang emulator is used.
+ </item>
+ </list>
+ If the provided public key is not found, the authentication fails.
+ </item>
+ <item>Finally, if the provided public key is found, the signature provided by the client is checked with
+ the public key.
+ </item>
+ </list>
+ </section>
+ <section>
+ <title>The Erlang/OTP SSH server after a succesful authentication</title>
+ <p>After a successful authentication an <i>Erlang process</i> is handling the service request from the remote
+ ssh client. The rights of that process are those of the user of the OS process running the Erlang emulator.
+ </p>
+ <p>If a shell service request arrives to the server, an <i>Erlang shell</i> is opened in the server's emulator.
+ The rights in that shell is independent of the just authenticated user.
+ </p>
+ <p>In case of an sftp request, an sftp server is started with the rights of the user of the Erlang emulator's OS
+ process. So with sftp the authenticated user does not influence the rights.
+ </p>
+ <p>So after an authentication, the user name is not used anymore and has no influence.
+ </p>
