This + could be useful for a networked machine that needs to come back + online as fast as possible after a lock-up. There's both a watchdog + implementation entirely in software (which can sometimes fail to + reboot the machine) and a driver for hardware watchdog boards, which + are more robust and can also keep track of the temperature inside + your computer. For details, read <file:Documentation/watchdog/watchdog.txt> + in the kernel source. + + The watchdog is usually used together with the watchdog daemon + which is available from + <ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>.
