Sending password over SSH
Hi guys,

I wrote a script that logs into around 30 nodes via SSH as root.

The issue is that I have to punch in the root password everytime and it is being a hassle.

Is there a way to save the password in a secure way and automate the whole procedure. I do not want to save the password in the script itself as that will be a security risk. The script is :

Code:
#!/bin/bash

for i in `cat nodes.txt`
do
echo $i
ssh root@$i "ps -ef | grep puppet | grep -v grep |awk '{print \$2}' | xargs kill -15 "
done

Sample output:

Code:
user1@server /scripts $ ./killpuppet.sh 
server1
Password:
server2
Password:
server3
Password:
server4
Password:
server5
Password:
