If it just contains IP addresses you can do:
for m in $(< file); do
ping $m -n 2
done

But I want to ping to different server not on the same.

Denis,

the below script what i've written, but my problem is how should i break my inner loop to restart the script again...

#!/bin/sh

for i in `cat /var/adm/crash/list`
do
remsh $i grep xx /etc/hosts > sss
OUT=$(awk '{print $2}' sss)
for l in `cat list2`
do
echo "#############"
echo $l
echo "#############"
remsh $l /etc/ping $OUT -n 4
echo
echo
done
\rm sss
done

Hi,
If your script is running fine then use while loop it will run till you break the loop with CTRL+C

while true
do
for i in `cat /var/adm/crash/list`
do
remsh $i grep xx /etc/hosts > sss
OUT=$(awk '{print $2}' sss)
for l in `cat list2`
do
echo "#############"
echo $l
echo "#############"
remsh $l /etc/ping $OUT -n 4
echo
echo
done
\rm sss
done
done

Well, you hav a two-node cluster and since you log it on the HP-UX forum, I presume you are running ServiceGuard, right ?

Then why won't you let ServiceGuard handle this ? It has built-in functionality to monitor IP-traffic to a card and restart/switch software when communication dies.

You can add "-m timeout" so ping times out.
