8 If you say Y here (and to one of the following options) and create a
9 character special file /dev/watchdog with major number 10 and minor
10 number 130 using mknod ("man mknod"), you will get a watchdog, i.e.:
11 subsequently opening the file and then failing to write to it for
12 longer than 1 minute will result in rebooting the machine. This
13 could be useful for a networked machine that needs to come back
e0845bf4 14 on-line as fast as possible after a lock-up. There's both a watchdog
1da177e4
LT
15 implementation entirely in software (which can sometimes fail to
16 reboot the machine) and a driver for hardware watchdog boards, which
17 are more robust and can also keep track of the temperature inside
e403149c

18 your computer. For details, read
19 <file:Documentation/watchdog/watchdog-api.txt> in the kernel source.

21 The watchdog is usually used together with the watchdog daemon
22 which is available from
23 <ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can
24 also monitor NFS connections and can reboot the machine when the process
25 table is full.

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