NAMEwd_keepalive − a simplified software watchdog daemon

---

SYNOPSISwd_keepalive [−c filename|−−config−file filename]

---

DESCRIPTIONThis is a simplified version of the watchdog daemon. It only opens /dev/watchdog, and keeps writing to it often enough to keep the kernel from resetting, at least once per minute. Each write delays the reboot time another minute. After a minute of inactivity the watchdog hardware will cause a reset. In the case of the software watchdog the ability to reboot will depend on the state of the machines and interrupts. The wd_keepalive daemon can be stopped without causing a reboot if the device /dev/watchdog is closed correctly, unless your kernel is compiled with the CONFIG_WATCHDOG_NOWAYOUT option enabled.

---

OPTIONSAvailable command line options are the following: −c config-file, −−config−file config-file  Use config-file as the configuration file instead of the default /etc/watchdog.conf.

---

FILES/dev/watchdog  The watchdog device. /var/run/wd_keepalive.pid  The pid file of the running wd_keepalive.
