Ping the hostname of many servers using a script


We have some 300 servers in the Data center and some of them are running with AIX and some of them are running with Solaris.
I need a script which can be run in one of the server and that script should ping the hostname of all the 300 servers.
Also the script should notify if any server is down.
Please assist in writing the script.

first thing that comes to mind is to use a simple configuration file that contains the name of all the servers to be pinged, one per line.

Then you could write a script that reads each line and for each hostname read it pings, like i.e.:

while read line
   #   one ping to the current hostname
   ping -c 1 ${line} > /dev/null 2>&1
   #   get the exit code of ping command
   if [ ${RETVAL} -ne 0 ] ; then
      #   log error somewhere, send a mail to someone, etc.
done < /path/to/config_file

see ya

What is the problem exactly, ping takes a -c <count> modifier to exit after count packets so if you have a file with all the hostnames in it.
for host in $(cat network_hosts);do 
   if [ ! "$( ping -c 1 $host 2>/dev/null| grep '1 received' )" ] ; then 
      echo "$host is unresponsive"

Below is the file containing the hostnames of all the servers
root@[/] #cat network_hosts

All the servers are live except as we have shutdown this lpar.

Please suggest me a script which will tell that "" is not alive and the rest are alive.

how should the script report the downed servers? (email, log file, a message on the screen,...)

What is not ok with the script frappa offered to you? What is missing? What did not work? Did you try it? Did you try anything?
Additionally just scroll down to the bottom of this thread and you see some similar threads where people try to ping hosts.
