- On your client, start the vncserver and connect to it by matching the final digit of the port number to the :X number you used to create it.

client should use the ip: 10.23.47.150:5904
- If you get an error starting the vncserver, increment the :2 to :3 or :4 and so forth until you find one not in use by some other user on the server.
