Important Features Of The Cli Utility - Avocent Cyclades ACS Command Reference Manual

2 ACS Advanced Console Server Command Reference Guide
Remote users may access the ACS console server CLI through SSH, by using a terminal
emulation program to dial into an external modem or by creating a PPP connection with an
external modem or a PCMCIA modem.
• By clicking Connect to ACS in WMI.
After logging into the WMI, you may access the CLI by clicking the Connect menu option.

Important features of the CLI utility

• Only one user logged in as "root" or "admin" may have an active CLI or WMI session. A
second user who connects through the CLI or the WMI as "root" or "admin" have a choice to
abort the session or close the other user's session.
NOTE: If there are cron jobs running through automated scripts, a root or admin user login may cause the
automated cron jobs to fail.
• CLI has three possible user levels:
• Root user - A Linux root user has access to the full functionality of the CLI interface. Root
users have access to the shell command in the CLI that provides access to the ACS
console server shell prompt.
NOTE: An administrator may enforce the Linux shell to execute the CLI utility when the user logs into the ACS
console server (/bin/CLI). A user with "root" access may invoke the Linux shell from the CLI interface. An admin
or a regular user who is configured with CLI as the default shell may not access the Linux shell.
• Admin - A Linux admin user has access to the full functionality of the CLI except the shell
command, which provides access to the ACS console server Linux shell prompt.
• Regular user - A Linux regular user has access only to limited functionality of the CLI.
Access is granted only to the applications commands of the CLI utility.
• CLI interface generates syslog messages for executed commands, and when sessions are
terminated. For example,
Apr 19 17:51:44 src_dev_log@swes-129 CLI[413]: User root starts an
interactive CLI session.cli>config
Apr 19 16:28:02 src_dev_log@swes-129 CLI[412]: Session closed due
idletimeout
Apr 19 17:54:23 src_dev_log@swes-129 CLI[413]: User root executed
[quit]
• CLI writes every command executed in interactive mode in the file ~/.history. This file stores
the last 1000 commands executed in any CLI session.
