Unless these machines have the same ssh host keys, you'll experience a nasty message when you attempt to log in, unless you only ever use port 922 or port 22.

Add this under the host config of each host that connects on an alternate port to make that go away:

     UserKnownHostsFile ~/.ssh/known_hosts.922

It will make the hosts file a different file on disk, so you won't have port 922 and 22 having different rsa fingerprints causing you grief, while retaining the ability to check that the host/port combinations rsa key.
