Homepage: http://watchdog.sourceforge.net
Description-en: system health checker and software/hardware watchdog handler
The watchdog program writes to /dev/watchdog every ten seconds. If
the device is opened but not written to within a minute, the machine
will reboot. This feature is available when the kernel is built with
"software watchdog" support (standard in Debian kernels) or if the
machine is equipped with a hardware watchdog (in which case this
package can also be used to "pet" it, resetting its timer).
.
The kernel software watchdog's ability to reboot will depend on the
state of the machine and interrupts.
.
The watchdog tool itself runs several health checks and acts
appropriately if the system is not in good shape.
