Creating Message of the Day for Administrators

Checking for ZCS Software Updates

The Zimbra command-line interface (CLI) is another method of configuring and maintaining the Zimbra system. The CLI tool set contains utilities that are not available through the administration console. The CLI options are executed on each server individually.

Use CLI command utilities for the following. See Appendix A Command-Line Utilities for details about the commands.

•	Start and stop services, CLI zmcontrol

•	Manage local server configuration, CLI zmlocalconfig

•	Create a message of the day to display on the administration console, CLI zmprov. See Setting up a Message of the Day.

Creating Message of the Day for Administrators

Global administrators can create messages of the day (MOTD) that can be viewed when global and delegated administrators log into the administration console.

A global or domain multi-value attribute, zimbraAdminConsoleLoginMessage, is used to create a MOTD. The message is created from the CLI zmprov.

Every time an admin logs in the message displays at the top left on the administration console. They can close the message. The message displays until it is replaced or removed.

Example of a Message of the Day

To create a message of the day

You can create a message globally or for a specific domain.

1.	To create by domain type:

 

zmprov md domainexample.com zimbraAdminConsoleLoginMessage “message to display”

The quotes must be used.

You can create more than one message to display. Run the command again to create additional messages, but add a plus sign (+) before the attribute, as in this example

 

zmprov md domainexample.com +zimbraAdminConsoleLoginMessage “second message to display”

To remove a message of the day

To remove a specific message, type the attribute, adding a minus sign (-) before the attribute and type the message as it is shown.

 

zmprov md domainexample.com -zimbraAdminConsoleLoginMessage “message to display”

To remove all messages, type the attribute and add a single quote at the end.

 

zmprov md domainexample.com zimbraAdminConsoleLoginMessage ‘’

 

Checking for ZCS Software Updates

When ZCS is installed, the ZCS software update utility is automatically configured to check for the latest ZCS version once a day and if there is an update to send notification to the address that is configured in the administration console’s Server Updates tab.

From this tab, you can configure the following:

•	Server that checks for updates. The pull-down tab lists all available servers. Only one server is configured. The selected server checks for updates and the result of the update response from www.zimbra.com is stored in LDAP.

•	Check for updates every ___. The default is to check once a day. You can change the frequency interval to check every x hours, minutes, or seconds. A cron job is configured to check for new updates. If the frequency interval is less than 2 hours, the crontab file must be modified.

•	Updates URL. This address is the URL that the server connects to when checking for updates. When a ZCS server checks for updates, it transmits its version, platform, and build number to Zimbra. Normally, this URL is not changed.

•	To be notified of updates, check the Send notification email when updates are available and enter the send to and send from addresses. The default address is the administrator’s address.

•	A generic email is created. The subject and content of the email can be changed.

When a server polls the URL specified, the response is displayed in the Updates tab.
