[CentOS] How to use watchdog daemon with hardware watchdog driver interface?

[Alexander Farber]

Hello Steve,

yes, I have that device:

# ll /dev/watchdog
crw-rw---- 1 root root 10, 130 Sep 17 23:21 /dev/watchdog

#  ps uawwx|grep w[a]tchdog
root         6  0.0  0.0      0     0 ?        S    Sep17   0:00 [watchdog/0]
root        10  0.0  0.0      0     0 ?        S    Sep17   0:00 [watchdog/1]
root        14  0.0  0.0      0     0 ?        S    Sep17   0:00 [watchdog/2]
root        18  0.0  0.0      0     0 ?        S    Sep17   0:00 [watchdog/3]
root        22  0.0  0.0      0     0 ?        S    Sep17   0:00 [watchdog/4]
root        26  0.0  0.0      0     0 ?        S    Sep17   0:00 [watchdog/5]
root        30  0.0  0.0      0     0 ?        S    Sep17   0:00 [watchdog/6]
root        34  0.0  0.0      0     0 ?        S    Sep17   0:00 [watchdog/7]
root     12175  0.0  0.0   6236  2140 ?        SLs  11:11   0:00
/usr/sbin/watchdog -v

# grep -v ^# /etc/watchdog.conf
ping                    = 144.76.XXX.XXX
admin                   = root
logtick                 = 360
realtime                = yes
priority                = 1

So you think killing with -9 will indicate
if I have hardware watchdog or just software?
