VAST OS is the operating system that runs on the management server and the other CNodes and DNodes in the cluster. The following settings apply to the VAST OS:

Changing the MOTD for VAST OS Login

VAST OS displays a message of the day (MOTD) banner on login. This MOTD appears, for example, when you connect to the management server via SSH in order to run the VAST CLI. The default MOTD displays the cluster name, cluster health status, and various networking information. You can replace this message with custom text.

Changing the MOTD from the VAST Web UI

To add a custom MOTD:

  1. Go to the Cluster page under the Settings menu.

  2. In the MOTD field, enter the custom text of your choice.

  3. Click Save and then Yes to confirm your changes.

To remove a custom MOTD:

  1. Click in the MOTD field.

  2. Delete the MOTD text.

  3. Click Save and then Yes to confirm your changes.

Changing the MOTD from the VAST CLI

To set a custom MOTD, use the cluster modify command with the --motd parameter. For example:

vcli: admin> cluster modify --motd 'This is the Message of the Day'

To remove a custom MOTD, specify an empty string in single quotes:

vcli: admin> cluster modify --motd ''

To see the current custom MOTD:

vcli: admin> cluster show --motd
+------+-------------------------------------+
| motd | This is the Message of the Day      |
+------+-------------------------------------+

Note

cluster show --motd displays any configured custom MOTD. It does not display the default MOTD that is used when no custom MOTD is configured.

Changing the Auto Logout Timeout for VAST OS

Auto logout timeout is a configurable period of inactivity after which VAST OS automatically logs out users who are logged in via SSH. '0', which is the default value, indicates an infinite period of inactivity.

Changing the Auto Logout Timeout from the VAST Web UI

To set an auto logout timeout:

  1. Go to the Cluster page under the Settings menu.

  2. In the Auto logout timeout field, enter the timeout in seconds.

  3. Click Save and then Yes to confirm your changes.

Changing the Auto Logout Timeout from the VAST CLI

To set an auto logout timeout, use the cluster modify command with the --auto-logout-timeout parameter and specify the timeout in seconds. For example, to set the logout period to 30 minutes:

vcli: admin> cluster modify --auto-logout-timeout 1800
