SSH Without a Password

On the client generate a new rsa ssh key.

NOTE: When prompted for a passphrase leave blank (just hit enter).

ssh-keygen -t rsa

From the client append the new key to the servers .ssh/authorized_keys file.

cat ~/.ssh/id_rsa.pub | ssh root@hostname_or_ip ‘cat >> ~/.ssh/authorized_keys’

NOTE: Enter the root password on the server for the last time.

Now ssh into the server

ssh -l root hostname

It should log in without any prompt for a password.
