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 Message of the Day for VAST OS Login
VAST OS displays a message of the day banner on login. This message appears, for example, when you connect to the management server via SSH in order to run the VAST CLI. The default message displays the cluster name, cluster health status, and various networking information. You can append custom text to this message or replace the message.
Changing the Message of the Day from the VAST Web UI
From the left navigation menu, select Settings and then Cluster.
Under General, in the Message of the Day field, enter the custom text of your choice.
Click Save and then Yes to confirm your changes.
Click in the Message of the Day field.
Delete the text.
Click Save and then Yes to confirm your changes.
Changing the MOTD from the VAST CLI
To set a custom message of the day to replace the default message, use the cluster modify command with the --motd parameter. For example:
vcli: admin> cluster modify --motd 'This is the Message of the Day'
To append a custom message to the default message of the day, use the cluster modify command with the --motd parameter and the --motd-append-to-default parameter. For example:
vcli: admin> cluster modify --motd 'This is the Message of the Day' --motd-append-to-default
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 --motddisplays 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
From the left navigation menu, select Settings and then Cluster.
Under General, in the SSH Auto logout timeout field, enter the timeout in seconds.
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
