is compiled for the underlying operating system (e.g. Unix/Linux
or Windows) during the build of the Erlang/OTP system, and is
@@ -43,67 +43,10 @@
The <c>ct</c> interface functions can be called from the Erlang shell,
or from any Erlang function, on any supported platform.</p>
- <p>A legacy Bourne shell script - named run_test - exists,
- which may be manually generated and installed. This script may be used
- instead of the ct_run program mentioned above, e.g. if the user
- wishes to modify or customize the Common Test start flags in a simpler
- way than making changes to the ct_run C program.</p>
-
<p>The Common Test application is installed with the Erlang/OTP
system and no additional installation step is required to start using
- Common Test by means of the ct_run executable program, and/or the interface
- functions in the <c>ct</c> module. If you wish to use the legacy Bourne
- shell script version run_test, however, this script needs to be
- generated first, according to the instructions below.</p>
-
- <note><p>Before reading on, please note that since Common Test version
- 1.5, the run_test shell script is no longer required for starting
- tests with Common Test from the OS command line. The ct_run
- program (descibed above) is the new recommended command line interface
- for Common Test. The shell script exists mainly for legacy reasons and
- may not be updated in future releases of Common Test. It may even be removed.
- </p></note>
-
- <p>Optional step to generate a shell script for starting Common Test:</p>
- <p>To generate the run_test shell script, navigate to the
- <c><![CDATA[common_test-<vsn>]]></c> directory, located among the other
- OTP applications (under the OTP lib directory). Here execute the
- <c>install.sh</c> script with argument <c>local</c>:</p>
-
- <p><c>
- $ ./install.sh local
- </c></p>
-
- <p>This generates the executable run_test script in the
- <c><![CDATA[common_test-<vsn>/priv/bin]]></c> directory. The script
- will include absolute paths to the Common Test and Test Server
- application directories, so it's possible to copy or move the script to
- a different location on the file system, if desired, without having to
- update it. It's of course possible to leave the script under the
- <c>priv/bin</c> directory and update the PATH variable accordingly (or
- create a link or alias to it).</p>
-
- <p>If you, for any reason, have copied Common Test and Test Server
- to a different location than the default OTP lib directory, you can
- generate a run_test script with a different top level directory,
- simply by specifying the directory, instead of <c>local</c>, when running
- <c>install.sh</c>. Example:</p>
-
- <p><c>
- $ install.sh /usr/local/test_tools
- </c></p>
-
- <p>Note that the <c><![CDATA[common_test-<vsn>]]></c> and
- <c><![CDATA[test_server-<vsn>]]></c> directories must be located under the
- same top directory. Note also that the install script does not copy files
- or update environment variables. It only generates the run_test
- script.</p>
-
- <p>Whenever you install a new version of Erlang/OTP, the run_test
- script needs to be regenerated, or updated manually with new directory names
- (new version numbers), for it to "see" the latest Common Test and Test Server
- versions.</p>

+<section>
+ <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. A minimum of
+ Message Authentication Code (MAC) and encryption
+ algorithms are supported. For details, see the
+ <seealso marker="ssh">ssh(3)</seealso> manual page in <c>ssh</c>.</p>
+ </section>
+
+ <section>
+ <title>Authentication Protocol</title>
+
+ <p>The SSH Authentication Protocol is a general-purpose user
+ authentication protocol run over the SSH Transport Layer
+ Protocol. The <c>ssh</c> application supports user authentication as follows:
+ </p>
+ <list type="bulleted">
+ <item>
+ Using public key technology. RSA and DSA, X509-certificates
+ are not supported.
+ </item>
+ <item>
+ Using keyboard-interactive authentication.
+ This is suitable for interactive authentication methods
+ that do not need any special software support on the client side.
+ Instead, all authentication data is entered from the keyboard.
+ </item>
+ <item>
+ Using a pure password-based authentication scheme.
+ Here, the plain text password is encrypted before sent
+ over the network.
+ </item>
+ </list>
+ <p>Several configuration options for
+ authentication handling are available in
+ <seealso marker="ssh#connect-3">ssh:connect/[3,4]</seealso>
+ and <seealso marker="ssh#daemon-2">ssh:daemon/[2,3]</seealso>.</p>
+ <p>
+ The public key handling can be customized by implementing
+ the following behaviours from <c>ssh</c>:</p>
+ <list type="bulleted">
+ <item>Module
+ <seealso marker="ssh_client_key_api">ssh_client_key_api</seealso>.
+ </item>
+ <item>Module
+ <seealso marker="ssh_server_key_api">ssh_server_key_api</seealso>.
+ </item>
+ </list>
+ </section>
+
+ <section>
+ <title>Connection Protocol</title>
+
+ <p>The SSH Connection Protocol provides application-support
+ services over the transport pipe, for example, channel multiplexing,
+ flow control, remote program execution, signal propagation, and
+ connection forwarding. Functions for handling the SSH
+ Connection Protocol can be found in the module <seealso
+ marker="ssh_connection">ssh_connection</seealso> in <c>ssh</c>.
+ </p>
+ </section>
+
+ <section>
+ <title>Channels</title>
+
+ <p>All terminal sessions, forwarded connections, and so on, are
+ channels. Multiple channels are multiplexed into a single
+ connection. All channels are flow-controlled. This means that no
+ data is sent to a channel peer until a message is received to
+ indicate that window space is available.
+ The <em>initial window size</em> specifies how many bytes of channel
+ data that can be sent to the channel peer without adjusting the
+ window. Typically, an SSH client opens a channel, sends data (commands),
+ receives data (control information), and then closes the channel.
+ The <seealso marker="ssh_channel">ssh_channel</seealso> behaviour
+ handles generic parts of SSH channel management. This makes it easy
+ to write your own SSH client/server processes that use flow-control
+ and thus opens for more focus on the application logic.
+ </p>
+
+ <p>Channels come in the following 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 into the
+ SSH daemon (server) by default, but it can be disabled. The Erlang <c>ssh</c>
+ daemon can be configured to run any Erlang-
+ implemented SSH subsystem.
+ </item>
+ <item><em>Shell</em> - Interactive shell. By default the
+ Erlang daemon runs the Erlang shell. The shell can be customized by
+ providing your own read-eval-print loop. You can also provide your
+ own Command-Line Interface (CLI) implementation,
+ but that is much more work.
+ </item>
+ <item><em>Exec</em> - One-time remote execution of commands. See function
+ <seealso marker="ssh_connection#exec-4">ssh_connection:exec/4</seealso>
+ for more information.</item>
+ </list>
+ </section>
+

+ following Request for Comments(RFCs):

- all needed applications (crypto, public_key and ssh). All examples
- are run in an Erlang shell, or in a bash shell using openssh to

- 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

- otptest's known_hosts file so that host verification can be done
- without user interaction.

+ Abstract Datatype for the Annotations of the Erlang Compiler
+ </modulesummary>
+
+ <description>
+ <p>This module implements an abstract type that is used by the
+ Erlang Compiler and its helper modules for holding data such as
+ column, line number, and text. The data type is a collection of
+ <marker id="annotations"><em>annotations</em></marker> as
+ described in the following.</p>
+ <p>The Erlang Token Scanner returns tokens with a subset of
+ the following annotations, depending on the options:</p>
+ <taglist>
+ <tag><c>column</c></tag>
+ <item><p>The column where the token begins.</p></item>
+ <tag><c>location</c></tag>
+ <item><p>The line and column where the token begins, or
+ just the line if the column unknown.</p>
+ </item>
+ <tag><c>text</c></tag>
+ <item><p>The token's text.</p></item>
+ </taglist>
+ <p>From the above the following annotation is derived:</p>
+ <taglist>
+ <tag><c>line</c></tag>
+ <item><p>The line where the token begins.</p></item>
+ </taglist>
+ <p>Furthermore, the following annotations are supported by
+ this module, and used by various modules:</p>
+ <taglist>
+ <tag><c>file</c></tag>
+ <item><p>A filename.</p></item>
+ <tag><c>generated</c></tag>
+ <item><p>A Boolean indicating if the abstract code is
+ compiler generated. The Erlang Compiler does not emit warnings
+ for such code.</p>
+ </item>
+ <tag><c>record</c></tag>
+ <item><p>A Boolean indicating if the origin of the abstract
+ code is a record. Used by Dialyzer to assign types to tuple
+ elements.</p>
+ </item>
+ </taglist>
+ <p>The functions
+ <seealso marker="erl_scan#column/1">column()</seealso>,
+ <seealso marker="erl_scan#end_location/1">end_location()</seealso>,
+ <seealso marker="erl_scan#line/1">line()</seealso>,
+ <seealso marker="erl_scan#location/1">location()</seealso>, and
+ <seealso marker="erl_scan#text/1">text()</seealso>
+ in the <c>erl_scan</c> module can be used for inspecting
+ annotations in tokens.</p>
