# Management from the command line

TrueConf Group endpoint can be managed not only with a remote control or via the web interface, but also with the command line interface (CLI). To use the command line, connect with any SSH application like PuTTy or OpenSSH.

This feature also makes it easy to integrate TrueConf Group into meeting room management systems and display the endpoint control buttons in the tablet interface.

# How to connect

Step 1. To connect to the endpoint from the command line, you should first set the access password:

/group/media/control_panel/set_cli_password/en.png

In the control panel, go to the Configuration → Maintenance section.
Specify the password needed for accessing the endpoint via SSH in the Password field of the API password section.
Click the Apply button to save the password. Due to security reasons the password will be hidden. However, you can always view it by clicking on the button .

Step 2. Now you will need to connect from an SSH client. The admin login is used:

Install (if you have not done it before) and run an SSH client; for example, you can use the OpenSSH package or any other. In many operating systems, it is available out of the box; for example, on Windows 10, you just need to run the following command:

ssh admin@[group_ip]

where [group_ip] is the IP address of your endpoint.

2. Enter the password created at step 1.

3. You will see the greeting text in the CLI of TrueConf Group. Now you can run any supported commands:

user@debian:~$ ssh admin@10.160.2.55
admin@10.160.2.55's password: 
Welcome to TrueConf Group Management Shell 1.1.0.470
(tcg cli)

The commands are case-insensitive, but all letters should be in the same case. For example, you can enter either HELP or help, but not Help.

To view the list of commands, type HELP.

To view information about the specific command [command], run [command] HELP.

The parameters (if they are present) have to be specified separated by a whitespace, for example, the command

CALLHISTORY 10

will list 10 most recent entries from the call history.
