I can now log in using ssh
ssh user@ip or ssh user@hostname
ssh -X user@ip to enable X forwarding
ssh -x user@pi disables X forwarding
If you are logged in to the desktop, and want to remotely browse the PI you can try sftp user@ip to connect, enter user name / password and you should be able to also copy files to / from the pi. You need the ssh server package running for this to work properly.
