Summary

This menu allows to configure system to reboot on kernel panic, when an IP address does not respond, or in case the system has locked up. Software watchdog timer is used to provide the last option, so in very rare cases (caused by hardware malfunction) it can lock up by itself. There is a hardware watchdog device available in all CableFree device PowerPC and Mipsbe models, which can reboot the system in any case.

Properties

Property Description
watch-address (IP; Default: none) The system will reboot in case 6 sequental pings to the given IP address (sent once per 10 seconds) will fail. If set to none this feature is disabled.
