Yes! It now works. However I get:
'The authenticity of host <host> cannot be established'
Is it something that I should worry about?
Maybe. As this is the first time you've successfully connected to the host you did not have a copy of the hosts public key in your ssh known_hosts file (located in ~/.ssh/known_hosts or for protocol 2 with older versions of openssh, ~/.ssh/known_hosts2). Therefore there is no way for your copy of ssh to verify the public key presented to you by the server is the correct one for that host. This key is, however, stored so should it change at a later date, you will be notified upon connect. This is how the server authenticates itself to you.
cat /etc/ssh_host*.pub or cat /etc/ssh/ssh_host*.pub should reveal the public ssh1/ssh2 rsa/dsa keys currently being used by sshd on the server, you can compare these to the one stored in ~/.ssh/known_hosts
