we are running 2 linux server in our network server1 is configured to shutdown automatically at a predefine time is there any way to shutdown server2 automatically only when server1 is shutting down. i want to automate the task thanks in advance

How about dumping something in /etc/init.d/rc0.d?

You can make shell script and put them to cron script.sh -- if a=`ping -q -c 1 -w 3 server_ip 2>/dev/null`; then printf "";else poweroff;fi -- If primary server not reply to ping query - secondary server turn off by command poweroff (also you can use command init 0) ----------- Sincerely, Andrew A.Romanchenko AlarIT programmer http://www.AlarIT.com

actually i donot want to ping server1 from server2 continuosly Any other method ? thanks
