7 | ---help--- | ||
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 | ||
14 | on-line as fast as possible after a lock-up. There's both a watchdog | ||
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 | ||
18 | your computer. For details, read <file:Documentation/watchdog/watchdog.txt> | ||
19 | in the kernel source. | ||
20 | |||
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. | ||

27 | If unsure, say N. | ||

32 | bool "Disable watchdog shutdown on close" | ||
33 | help | ||
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. | ||
