I am working on the Centos wiki instructions for doing an install via
vnc:

CD is all burned and ready to go. I then thought about the viewer
settings particularly the port number and firewall rules.
When I connect vncviewer to a vncserver it uses port(s) 590n where n
is the display number. OK, is that what happens when a server
connects back to a -listen viewer?
No
Seems not. According to the man page, it seems the default is port
5500, so I have to open up this port on the 'client' system and of
course allow it through my internal firewall (or put the install
system on the same subnet as the client and not the one with the repo
server).
Do I have this figured out right?
Yes. Port 5500 is the correct one, and you might need to also have
access to port 5900 on the new install machine just in case you get
disconnected. Then you can re-connect and finish.
Oh course, I will have to know its dhcp leased address, but not so hard,
only 2 such on that subnet.
I don't know if I would be comfortable installing over the internet
with VNC since it is clear-text, but I guess it would be OK. I would
change passwords on the new system after it is up just to feed my
paranoia.
Oh, all internal 'intra-nets'. I just have all of my production and lab
nets connected to a firewall to control what goes on between them.
Simple to add port 5500 to the vnc service definition.
