Well, I'm not a huge fan of just running vnc as it's insecure.  I prefer
to tunnel it via ssh, in which case you only need to open the ssh port
(TCP port 22).  However, raw VNC servers use TCP port (5900 + the number
of the display). So, for the first display, TCP 5900.  For the second,
port 5901 and so on.

rsync uses port 873, both TCP and UDP.
