How To Configure A Linux Shutdown Action In Device ManageR

The Linux Shutdown action is used to shut down target Linux systems; this action is extremely beneficial for powering down a system or group of systems when environment conditions, such as high temperatures, power loss, flooding, etc., could potentially lead to catastrophic system damage. Systems can be shutdown simultaneously, sequentially, or according to a defined schedule.

The plugin has been tested extensively with Ubuntu, Fedora and OpenSuse; as it uses the standard ‘shutdown’ command, all Linux distributions should be supported. This plugin uses Telnet to connect to the target Linux system, so that system must have the Telnet daemon installed and running.

To create a Linux Shutdown action, first download and install the Linux Shutdown Plugin from your account at RoomAlert.com.

Then you may create your Linux Shutdown action by following these steps:

1. Open Device ManageR in your web browser. You may open it by entering ‘localhost:8080’ or ‘<IP address of Device ManageR’s host system>:8080’ in your browser’s address bar.

2. Select Alerts / Tasks in the navigation bar to the left.

3. In the Settings menu, select Actions.

4. Select Add at the bottom of the screen to open the Add New Action window.

5. In the Add New Action window, enter a name for the action in Name. In our example, we’ve called the action ‘My Linux Shutdown Action.’

6. (Optional) In Description, you may, if you wish, enter any notes you feel would be helpful.

7. In Action Type, select the action you wish to execute from the drop-down list. Once you make your selection, options unique to that action will appear.

– In Action Type, select Shutdown A Linux System.

– There are several fields unique to this action:

– IP or System Name field is the IP address or computer name of the system that the action will send the shutdown command to when an action is performed.

– Username field is the name of the user account used for accessing the target system.

– Password field is the password for the user account used for accessing the target Linux system.

– Port Number field is the port on the target system that is accepting telnet connections.

– Login Prompt field is the expected message returned by the target system to start the login process.

– Password Prompt field is the expected message returned by the target system to indicate the time to send the password

– System Prompt are the characters received when the terminal is ready for a command.

– Logout Command is the command used to log out of the telnet session.

– Timeout is the time that the Telnet connection should stay open for when waiting for a response or attempting to send a command.

8. In If not successful, retry this Action, you may leave the default, 0, or enter a higher number.

9. (Optional) If you wish, you may associate a schedule with this action by selecting Optional Schedule and choosing a schedule from the drop-down list. (If you attach a schedule to the action, it can be performed only during the hours you’ve set up in the Optional Schedule.)

10. Then select Save to save the action.

11. Once you’ve saved, your action will appear in your Actions list.

You may now associate this action with an Action / Notification List. Please see this FAQ for more information: How To Configure Action / Notification Lists In Device ManageR.
