Vnc server problem on RHEL 5.2
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
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?
