Shutdown automatically if host  is not reachable
If you want to shutdown the system whether a host is not reachable anymore you can use monit to do this. The default poll cycle is 30 seconds, so if the host is not reachable after 5 minutes the following configuration example will shutdown the system.

check host with address  if failed icmp type echo count 10 with timeout 15 seconds then exec "/sbin/shutdown -h now No clients available, time to sleep" monit reload
 * Create the monit service configuration file at /etc/monit/conf.d/shutdown
 * Force monit to reload the configuration

Please check the monit man page to get more details.

Auto OFF (German only)
The following page describes how to shutdown the system if it is not used anymore.

Environment variables
The web UI cannot provide access to ALL the configuration aspects of a complex system like OMV. However, the system allows to change some advanced settings through the use of environment variables. Please see Environment Variables.
