Vnc server problem on RHEL 5.2

[George Magklaras]

Could you specify:

1) Which Xvnc server you are using (RedHat's ?

2)How do you start it exactly?

3)How exactly are you trying to access it from the clients?

If you are not trying to start or connect in the wrong way, I don't 
recall if RedHat's Xvnc uses tcp wrappers. If the port is listening 
(lsof -i | grep Xvnc) the other thing that could be blocking it is tcp 
wrappers. Have you got anything under /etc/xinetd/ or in 
/etc/hosts.allow  /deny?

Also what's the nmap's output. Does it say that the port is there but 
filtered or does it state that the port is closed?
