[CentOS] VNC

[Terre Porter]

The instructions out linked to has a type-o at the end says to connect to
ip:5801 should be 5901.

If your using a vnc client uvnc,  tightvnc..  try using just the ip without
the :port part or :1 for the 5901.

Try  lsof -i -P | grep -i "listen"

To see what ports are listening...

OK, with this file I'm getting connection timed out - before I was getting
connection refused so I guess that's some progress.
