That was good advice. Besides sorting out the keys and fingerprints, the user account 'backuppc' that was created by the installer did not have a login shell. The important step was to log in on phoenix as backuppc user, and then 'ssh backuppc@phoenix'. Once I got the login and ssh connection part solved the rest went easier. For security the backuppc password can be locked once the ssh connection is working.
