FWIW you don't need the 5811, because netstat shows you all the ports.

Hmm.  Everything looks ok here.  I should have had you run "netstat -atp" to verify that it is VNC listening, but I bet it is.

This looks pretty normal.  The "Window manager warning" is a known issue with rhn-applet.

I don't see any attempts to connect in the log file, though.  Had you just started the server?

You might also attempt to telnet into the VNC port (from fc2-station-1):

telnet localhost 5911

Possibly you have a firewall blocking access from another PC?
