10 If you say Y here (and to one of the following options) and create a
11 character special file /dev/watchdog with major number 10 and minor
12 number 130 using mknod ("man mknod"), you will get a watchdog, i.e.:
13 subsequently opening the file and then failing to write to it for
14 longer than 1 minute will result in rebooting the machine. This
15 could be useful for a networked machine that needs to come back

Linus Torvalds1da177e2005-04-16 15:20:36 -070017 implementation entirely in software (which can sometimes fail to
18 reboot the machine) and a driver for hardware watchdog boards, which
19 are more robust and can also keep track of the temperature inside
20 your computer. For details, read <file:Documentation/watchdog/watchdog.txt>
21 in the kernel source.
22
23 The watchdog is usually used together with the watchdog daemon
24 which is available from
25 <ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can
26 also monitor NFS connections and can reboot the machine when the process
27 table is full.

34 help
35 The default watchdog behaviour (which you get if you say N here) is
36 to stop the timer if the process managing it closes the file
37 /dev/watchdog. It's always remotely possible that this process might
38 get killed. If you say Y here, the watchdog cannot be stopped once
39 it has been started.
