Why were you thinking you wouldn't be prompted for a password? In
order to do passwordless ssh you need to do the following:

1) On your local system run ssh-keygen and use a good passphrase when
prompted

2) Copy the contents of ~/.ssh/identity.pub from the local system to
~/.ssh/authorized_keys on the remote system.

3) Make sure your ssh daemon on the remote system has, at least, the
following in it's configuration file:

        RSAAuthentication yes


That should get you going for passwordless ssh between the two.
