-\section abstract Abstract
|
|
|
|
|
-A modular framework for implementing a CISCO-like CLI on a *NIX system.
|
|
|
|
|
-Arbitary command menus and actions can be defined using XML files.
|
|
|
|
|
-This software handles the user interaction, and forks the appropriate system
|
|
|
|
|
-commands to perform any actions.

-\section background Background
|
|
|
|
|
-The CISCO-like CLI has become a de-facto standard in the domain of network
|
|
|
|
|
-devices. It is a much more restricted interface than traditional *NIX shells,
|
|
|
|
|
-hence is simpler to use and inherently more secure. As more devices move to
|
|
|
|
|
-using an embedded *NIX operating systems, a simple, scalable means of producing
|
|
|
|
|
-such a CLI becomes valuable.

|

|
|
|
-\subsection Libcli
|
|
|
|
|
-<A HREF="http://libcli.sourceforge.net/">Libcli</A>
|
|
|
|
|
-provides a similar facility but has the following main limitations:-
|
|
|
|
|
-
|
|
|
|
|
-1) In order to add new commands a monolithic executable (which uses the
|
|
|
|
|
- library) needs to be recompiled, after editing the source code to add the
|
|
|
|
|
- newly required commands and actions.
|
|
|
|
|
-
|
|
|
|
|
-2) libcli takes responsiblity for attaching to a socket (telnet-like). This
|
|
|
|
|
- limits the usage of the CLI; difficult to use over SSH for example, similarly
|
|
|
|
|
- cannot get the menus directly from an existing shell.
|
|
|
|
|
-
|
|
|
|
|
-3) The implementation of the command actions is hard-linked into the monolithic
|
|
|
|
|
- executable, this can cause licence concerns/issues when a commercial company
|
|
|
|
|
- wishes to control proprietry software from within the CLI.
|
|
|
|
|
-
|
|
|
|
|
-4) libcli takes responsiblity for the authentication of the user. This is
|
|
|
|
|
- different from other "shells" which do not deal with authentication, but are
|
|
|
|
|
- simply spawned as the required user.

-\subsection GNU-zebra
|
|
|
|
|
-<A HREF="http://www.zebra.org/">Zebra</A>
|
|
|
|
|
-is a routing package, and comes with it's own integrated CLI, to handle its
|
|
|
|
|
-configuration (VTYSH).
|
|
|
|
|
-
|
|
|
|
|
-\section project CLISH Project
|
|
|
|
|
-The project is written (mostly) in ANSI-C and provides two example executables
|
|
|
|
|
-which can be used as a drop-in replacement for a more conventional "shell".
|
|
|
|
|
-
|
|
|
|
|
-The software was initially developed as part of some internal work at 3Com and
|
|
|
|
|
-due to the dependancy on 3rd party open-source packages, and it's self contained
|
|
|
|
|
-nature, it is being released into the public domain.
|
|
|
|
|
-
|
|
|
|
|
-It is designed to run on any *NIX system e.g. Linux, BSD, Cygwin and makes use
|
|
|
|
|
-of the following other opensource packages (glibc,tinyxml,doxygen)
|
|
|
|
|
-
|
|
|
|
|
-\subsection clish clish (pronounced see-lish)
|
|
|
|
|
-This application is a standard UNIX shell replacement. The ACTION tags in the XML
|
|
|
|
|
-specification are mapped to the system() call and hence will be interpreted as
|
|
|
|
|
-a Bourne-shell script.
|
|
|
|
|
-
|
|
|
|
|
-\subsection tclish tclish (pronounced tickle-ish)
|
|
|
|
|
-This application is built if the TCL libraries are present on the build system.
|
|
|
|
|
-The name of the executable produced will reflect the version of TCL used. e.g.
|
|
|
|
|
-tclish8.4 will be generated if TCL8.4 is present on the system.
|
|
|
|
|
-
|
|
|
|
|
-This application will spawn a TCL interpreter when started, and the contents of
|
|
|
|
|
-the ACTION tags will be interpreted as TCL scripts within that interpreter for
|
|
|
|
|
-the duration of the shell.
|
|

-\subsection Features
|
|
|
|
|
-The "clish" shell has the following features:-
|
|
|
|
|
-
|
|
|
|
|
-- Provides CLI tree handling facilities
|
|
|
|
|
- - Tree built from multiple XML encoded files. (uses tinyxml)
|
|
|
|
|
- This means that XML configuration files can be be made part of
|
|
|
|
|
- 3rd party packages and simply installing them integrates
|
|
|
|
|
- commands into the CLI.
|
|
|
|
|
-
|
|
|
|
|
-- Access permissions are defined as part of the CLI tree definition; a CLI
|
|
|
|
|
- node/branch may be limited to a specific *NIX group.
|
|
|
|
|
-
|
|
|
|
|
-- Provides interface to user
|
|
|
|
|
- - Handles auto-completion of commands
|
|
|
|
|
- - Only appropriate commands for the current user's "group" will be
|
|
|
|
|
- available.
|
|
|
|
|
- - Provides parameter type verification facility
|
|
|
|
|
- * Each parameter may be of a specific type, which the
|
|
|
|
|
- framework will ensure is correctly entered by the user.
|
|
|
|
|
- - Provides key-handling for the interface (uses tinyrl)
|
|
|
|
|
- * Provides command line editing facilities
|
|
|
|
|
- * up/down arrow keys
|
|
|
|
|
- * [TAB] command completion
|
|
|
|
|
- * [CTRL-A] move to start of command line
|
|
|
|
|
- * [?] provides context sensitive help.
|

|
|
|
|
-- Able to be launched non-interactively
|
|
|
|
|
- - textual scripts can be written to drive the CLI
|
|
|
|
|
-
|
|
|
|
|
-- Executes a specified CLI command by launching the appropriate
|
|
|
|
|
- (as defined in the CLI tree) system command line to perform the
|
|
|
|
|
- required action
|
|
|
|
|
- - Only commands permitted for the current user are available.
|
|
|
|
|
- - During execution the I/O streams are handed over to the new
|
|
|
|
|
- program.
|
|
|
|
|
- - Able to spawn a 3rd party shell, where necessary
|
|
|
|
|
- This will take over control of the I/O channel until that
|
|
|
|
|
- sub-shell exits.

|
|
|
|
|
-
|
|
|
|
|
-- Identify scope of the commands (global or specific view(s))
|
|
|
|
|
-
|
|
|
|
|
-- Include access permissions. By default a command will be
|
|
|
|
|
- accessible to all users, but the schema will provide
|
|
|
|
|
- the ability to limit the command based on UNIX group membership.
|
|
|
|
|
-
|
|
|
|
|
-- Includes help text for menus
|
|
|
|
|
-
|
|
|
|
|
-- Includes parameter definitions (with types where appropriate)
|
|
|
|
|
-
|
|
|
|
|
-- Includes prompt modifications (different views)
|
|
|
|
|
-
|
|
|
|
|
-- Includes full command line which each leaf node should execute
|
|
|
|
|
- to achieve result.
|
|
|
|
|
-
|
|
|
|
|
-- Separate set of files for each localization (language) can be
|
|
|
|
|
- provided and determined by the user logging in.
|
|
|
|
|
-
|
|
|
|
|
-- "packages" can contribute files to define their facilities
|
|
|
|
|
- within the CLI; this makes augmentation of the CLI as simple
|
|
|
|
|
- as including/excluding a particular package.
