Script to push any script to all the servers in a unix environment

It is always helpful for any dba to have a script that can push any regularly used scripts to all the servers. In my case, we had a centralized server where have all the scripts and there was authentication setup, either remsh or ssh. The script below checks if 1) it can ping the server, 2) if it can ping it, can it ssh? 3) If it cannot ssh, can it remsh?

I run this script from Sun OS. If you run it from any other OS like linux, the ping command would be different. Change it accordingly.

Operating System : SunOS

===================== Script start ==================================

cat push_script.sh

#!/usr/bin/ksh

list=`cat /tmp/complete_server_list.lst`

for i in $list

do

ping -s $i 64 1 |grep -w "0% packet loss" # Check if we can ping the server

if [[ $? -eq 0 ]];then

ssh -o BatchMode=yes $i /bin/true # Check if ssh is enabled, if not use remsh/rcp

if [[ $? -eq 0 ]];then

scp -p /tmp/test_script $i:/tmp/test_script

else

rcp -p /tmp/test_script $i:/tmp/test_script

fi

else

echo "${i}" >> /tmp/cantping.lst

fi

done

===================== Script End==================================
