The below sh script trigger rebooting server if Google DNS does not respond |
#!/bin/sh ping -w 10 -c 1 8.8.8.8 if [ $? = 0 ] then echo noreply else /sbin/reboot fi |
In the AsusWrt, the below script works good
#!/bin/ash if [ $( ping -c 1 google.com | grep ttl | wc -l ) -eq 0 ] then echo noreply /sbin/reboot else echo "google.com is reachable" fi |
