To setup an SSH login to a server without prompting for a password:

Create a personel ssh key(Do not enter a passphrase when prompted otherwise you will have to enter the passphrase to login)

This will create two new files in your ~/.ssh folder

id_dsa
id_dsa.pub

Now copy the id_dsa.pub file to the remote server

scp ~/.ssh/id_dsa.pub user@:/root/.ssh/server1.key.pub

Now login to the remote server and

cat /root/.ssh/server1.key.pub >> /root/.ssh/authorized_keys2
chmod 600 /root/.ssh/authorized_keys2
/etc/init.d/sshd restart


Now you can login from your system to the remote host without a password!
