There's a lot of conflicting information on this topic on the
Internet. Most current VNC servers seem to listen on port 590n. I've
seen it claimed that a) port 580n is not used and can be blocked, b)
580n is used for the Java VNC client, c) 580n is used for browser
requests for VNC (probably via the Java VNC client, I'd guess).
I don't know when the change occurred and it may be that it happened
when RH changed from one VNC brand to another.
