  7. If you say Y here (and to one of the following options) and create a
  8. character special file /dev/watchdog with major number 10 and minor
  9. number 130 using mknod ("man mknod"), you will get a watchdog, i.e.:
  10. subsequently opening the file and then failing to write to it for
  11. longer than 1 minute will result in rebooting the machine. This
  12. could be useful for a networked machine that needs to come back
  13. on-line as fast as possible after a lock-up. There's both a watchdog
  14. implementation entirely in software (which can sometimes fail to
  15. reboot the machine) and a driver for hardware watchdog boards, which
  16. are more robust and can also keep track of the temperature inside
  17. your computer. For details, read
  18. <file:Documentation/watchdog/watchdog-api.txt> in the kernel source.
  19. The watchdog is usually used together with the watchdog daemon
  20. which is available from
  21. <ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can
  22. also monitor NFS connections and can reboot the machine when the process
  23. table is full.

  29. The default watchdog behaviour (which you get if you say N here) is
  30. to stop the timer if the process managing it closes the file
  31. /dev/watchdog. It's always remotely possible that this process might
  32. get killed. If you say Y here, the watchdog cannot be stopped once
  33. it has been started.
