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:

HTML::FormHandler::Field::Password(3pm) 		User Contributed Perl Documentation		   HTML::FormHandler::Field::Password(3pm)

NAME
HTML::FormHandler::Field::Password - password field VERSION
version 0.40013 DESCRIPTION
The password field has a default minimum length of 6, which can be easily changed: has_field 'password' => ( type => 'Password', minlength => 7 ); It does not come with additional default checks, since password requirements vary so widely. There are a few constraints in the HTML::FormHandler::Types modules which could be used with this field: NoSpaces, WordChars, NotAllDigits. These constraints can be used in the field definitions 'apply': use HTML::FormHandler::Types ('NoSpaces', 'WordChars', 'NotAllDigits' ); ... has_field 'password' => ( type => 'Password', apply => [ NoSpaces, WordChars, NotAllDigits ], ); You can add your own constraints in addition, of course. If a password field is not required, then the field will be marked 'noupdate', to prevent a null from being saved into the database. ne_username Set this attribute to the name of your username field (default 'username') if you want to check that the password is not the same as the username. Does not check by default. AUTHOR
