Introduction, Navigation and Commands
1
The Cyclades™ ACS 6000 advanced console server is a 1U appliance that serves as a single point for access and administration of connected devices, such as target device consoles, modems and power devices. Console servers support secure remote data center management and out-of-band management of IT assets from any location worldwide.
On console servers, administration can be performed and connected devices can be accessed with the Command
Line Interface (CLI) utility, with the web manager or with DSView
™
3 management software (version 3.5.1 and greater). Multiple users and administrators can be logged into the console server and connected to ports at the same time.
This guide describes how to access and navigate the CLI utility and how to use it after the console server has been installed and assigned an IP address. For information on how to install or operate your console server using the web manager, see the Cyclades ACS 6000 Installation/Administration/User Guide.
The console ports of servers, external modems or power distribution units (PDUs) can be connected to serial ports on the console server. Supported PDUs include Avocent PM1000/2000/3000s, Cyclades PM IPDUs, Avocent SPC power devices and Server Technology CDUs. Either a PDU or an external modem can be connected to the
AUX/Modem port if the port is not factory-configured for an internal modem.
Console server ports are shown in the following figure, and descriptions are listed in Table 1.1.

If an internal modem is ordered and factory installed, this port is configured internally as a modem port. If an internal modem is not installed, the port is configured as an auxiliary port, and a PDU or an external modem can be connected to it. The figure shows an external modem connected.
5 Console Port
Access Options and How to Log Into the CLI
The CLI utility can be accessed in the following ways:
• Through a local terminal or a computer that has a terminal emulation program connected to the console port of the console server with session settings of 9600, 8, N and 1, with no flow control.
• After the console server is connected to the network and has an IP address, it can be accessed by one of the following methods:
• An SSH or Telnet client on a remote computer (if the SSH or Telnet protocol is enabled in the selected
Security Profile)
• With the Web Manager - Overview - Appliance Session button
• With DSView 3 management software
NOTE: For details on the remote access methods and IP address configuration options, see the Cyclades ACS 6000
Installation/Administration/User Guide.
Administrators have full access to the CLI and to connected devices. An administrator can authorize regular users to access ports, manage power, manage data buffer storage and use one or more console server administration tools. Users can always change their own passwords.
To start the CLI:
1.
Access the CLI through the console port, with Telnet, SSH or through the web manager.
2.
Enter the username and password at the prompt. The cli-> prompt appears.
Welcome to ACS6000 <host name>.
Type help for more information
--:- / cli->
NOTE: The default password for admin is avocent and for root is linux. The password for these users may have been changed during installation of the console server. If not, change the default root and admin passwords to avoid potential security breaches.
Configuration Tasks Performed With the CLI
NOTE: This manual provides some configuration procedures as examples of how to use the CLI; an administrator who wants to use the CLI for configuration should reference the installation/administration/user guide for more information.
The navigation structure of the CLI mirrors that of the web manager. Options and parameters are also the same, except that spaces in web manager options and parameters are replaced with underscores (_), as in: system_tools.
Chapter 1: Introduction, Navigation and Commands
3
Examples that show how to select an option in the web manager use a dash surrounded by two spaces ( - ). In the CLI, two similar options in a path are separated by a forward slash (/).
For example, in the web manager, user configuration is done when an administrator selects - Users - Local
Accounts - User Names to get to the User Names screen. To navigate to the equivalent configuration level in the
CLI, an administrator would use the cd command followed by the path: cd /users/local_accounts/user_
names.
Administrators should log into the CLI in one window and log into the web manager in another window to see how the menu options in the web manager map to the navigation options in the CLI. Configuration with the CLI also requires mastery of the following information on CLI navigation and of the CLI commands shown in
Chapter 2.
CLI Navigation
The CLI navigation options are in a nested tree configuration.
NOTE: When a command line is shown in an example, and the step starts with “Enter,” or when a syntax example is given, the user should type the command as shown and then press Enter. The Enter key is not shown in command line examples unless needed for clarity.
When a user logs in the CLI, the prompt indicates the user is at the / level.
--:- / cli->
No parameters can be set at this level of the navigation tree.
At any CLI prompt at any level, if you type cd and press Tab Tab, the navigation options (path elements) for that level are listed. Different options appear for administrators and for authorized users.
• When an administrator types the cd command and then presses Tab Tab at the / prompt, the following navigation options (path elements) appear.
--:- / cli-> cd<
Tab><Tab> access/ active_sessions/ system_tools/ authentication/ change_password/ events_and_logs/ monitoring/ network/ pluggable_devices/ ports/ power_management/ system/ users/
When a regular user types the cd command and then presses Tab Tab at the / prompt, the following navigation options appear.
--:- / cli-> cd<
Tab><Tab> access/ power_management/
Enter cd <one_or_more_path_elements> to move down one or more levels of the navigation tree:
--:- / cli-> cd system_tools
A prompt like the following appears at each level:
--:- system_tools cli->
NOTE: CLI commands are case sensitive.
4 Cyclades™ ACS 6000 Advanced Console Server
At any level, you can press Tab Tab at the prompt to see the commands that can be entered at the current level.
---:- system_tools cli-><
Tab><Tab> batch_mode ls scp cd opiepasswd shell commit passwd show echo pwd shutdown exit quit upgrade_firmware ftp reboot whoami help restore_configuration wiz hostname revert list_configuration save_configuration
---:- system_tools cli->
If you know the path, you can enter multiple path elements in a single command separated with forward slashes
(/).
--:- / cli-> cd ports/serial_ports/
--:- serial ports cli->
Enter cd .. to move up one level of the navigation tree. Enter cd ../..[/..] to move up multiple levels.
--:- serial ports cli-> cd ../..
--:- / cli->
Autocompletion
Autocompletion allows you to type the first few letters of a command or navigation option and then press Tab.
The rest of the name is filled in automatically if the letters typed are unique to one command or to a navigation option at that level. If the letters match more than one of the commands or navigation options for that level, the matching options are listed.
For example, if you type cd acc and press Tab at the CLI prompt from the / level, the access option will be completed.
--:- / cli-> cd acc
<Tab>
--:- / cli-> cd access
If you then press Enter, you are changed to the access level, and the access level prompt appears.
--:- access cli->
The following example illustrates a case when more than one command matches the letters typed.
--:- / cli-> sh
<Tab>
shell show
Parameters
Some CLI commands take parameters. If you press Tab Tab after a command that requires a parameter, you are prompted to enter the parameter.

Port Access and Configuration Examples
19
By default, all serial ports and the AUX/Modem port are disabled. An administrator must enable and configure the ports before anyone can use them. Configuration of ports differs based on the type of connected device, which can be either a device console, a PDU or modem.
By default, all users can access all enabled and configured ports. The administrator must decide whether to restrict user access to ports by the assignment of authorizations to user groups. A user who is in an authorized group is referred to as an authorized user.
Some port configuration tasks are provided as examples of how to use the CLI. See the Cyclades ACS 6000
Installation/Administration/User Guide for an overview of the tasks the administrator must do to configure restricted access to ports. For more information about how to follow the web manager procedures in the CLI, see
Configuration Tasks Performed With the CLI on page 2.
This section describes the following tasks related to port access, configuration, power management and where the tasks are performed in the CLI.

Appendix B: Migration CLI
The Migration CLI is a tool that allows you to configure an ACS 6000 console server that is running scripts based in the ACS advanced console server. For full configuration and management commands, it is recommended you use the ACS 6000 console server’s CLI.
NOTE: References to an ACS advanced console server in this section refer to any advanced console server other than the ACS 6000 console server.
In the ACS 6000 console server, the login profile for the user “root” goes directly to the shell prompt. This will allow the root user to run Migration CLI commands out of the ACS 6000 console server. A new group, “loginprofile-shell,” is created with only root as a member. To run commands based from an ACS advanced console server, a root user should type CLI before the command.
Access rights
The access rights on the ACS 6000 console server are based on authorization groups. The administrator configures the serial ports the group can access. To allow you to configure access rights, the following table displays authorization groups that will be created on the ACS 6000 console server when using the Migration
CLI.
Table B.1: Access Rights Groups
Group Members Permissions cli_mus_ttySxx
Users who can open a second session to a serial port.
cli_power_ ttySxx cli_access_ ttySxx cli_pmd_
<username>
Users who have power control in a serial port.
Users who can access a serial port in a single session.
<username>
Access to a serial port in a muli-session (read/write or read only)
Power control (on/off/cycle) of outlets merged to a serial port.
Access to a serial port in a single read/write session.
Power control of the outlet.
Exceptions
This section will list all ACS advanced console server CLI commands not available in the Migration CLI for the
ACS 6000 console server. For a list of available commands, see the Cyclades ACS
Installation/Administration/User Guide.

Appendix C: Su and Sudo Commands
The su and sudo commands allow a user to execute commands as a different user.
Su command
Using the su (switch user) command, a user can switch to another user account to execute commands not authorized with their normal account. If used without a username, the su command defaults to root. Only users who are members of the wheel group can execute the su command to log in as root.
NOTE: The wheel group is a Linux group and is included in the firmware by default.
You will be prompted for the password of the account you’re trying to switch to with the su command. You will remain logged into that account until you either press Ctrl-D or type exit.
NOTE: The su command will open a shell session instead of the restricted shell. The user will receive the shell prompt. Improper use of shell commands could lead to data loss. Double-check your syntax when using shell commands.
Syntax: su [options][-][username[arguments]]
The following table describes options that can be used with the su command.
Table C.1: Su Command Options
Option Description
-, -l, --login
Uses an environment similar to that had the user logged in directly. When - is used, it must be specified as the last su option.
-m, -p, --preserveenvironment
Preserves the current environment.
Optional arguments may be provided after the username, in which case they are supplied to the shell (/bin/sh).
To add a member to the wheel group:
1.
Create the user using the web manager or CLI.
2.
Open a session in the appliance and log in as root.
3.
In the shell prompt, run the usermod command to add the user to the wheel group.
# usermod -G wheel <username>
4.
Run the groups command to verify.
# groups <username>
To delete a member from the wheel group:
1.
Edit the file /etc/group.
2.
Remove the username from the line with wheel::XX:<user1>,<user2>,<user3>.
Sudo command
Using the sudo (superuser do) command, a user can execute a command using the privileges of another user
(often root), as specified in the /etc/sudoers file. The user is authenticated using his own password, not the root
Appendices
46
password. The /etc/sudoers file logs all commands and arguments.
Syntax: sudo <command>
Configuring sudo
A system administrator configures the /etc/sudoers file to give groups or users access to some or all commands not authorized with their normal account. An administrator should log into the console server as a root user and edit the /etc/sudoers file by using the /usr/sbin/visudo command to configure sudo.
The sudoers file is composed of aliases and user specifications. When multiple entries match for a user, they are applied in order. Where there are conflicting values, the last match is used.
Since the sudoers file is parsed in a single pass, order is important. You should structure sudoers so that the
Host_Alias, User_Alias, and Cmnd_Alias specifications come first, followed by any Default_Entry lines, and finally the Runas_Alias and user specifications.
An example of an /etc/sudoers file:
#User alias specification
User_Alias FULLTIMERS = millert, mikef, dowdy
User_Alias PARTTIMERS = bostley, jwfox, crawl
#Cmnd alias specification
Cmnd_Alias KILL = /bin/kill
Cmnd_Alias SHUTDOWN = /sbin/shutdown
Cmnd_Alias REBOOT = /sbin/reboot
Cmnd_Alias SU = /bin su
FULLTIMERS ALL = KILL, SHUTDOWN, REBOOT, SU
PARTTIMERS ALL = SHUTDOWN, REBOOT
In the preceding example, the users millert, mikef and dowdy can execute the kill, shutdown, reboot and su commands while the users bostley, jwfox and crawl can only shut down and reboot the console server.
