At school and my moms house I'm forced to use a windowsXP machine, and I wanted to set up a VNC server on my home machine so that I can use it remotely, as I have done in the past.

Linux machine is Fedora Core 6, it is in the DMZ with the firewall allowing port 5901. An NMAP scan of my linux machine from my moms winXP machine shows that 5901 is open.

I'm running tightVNC on the fedora machine, and use the windows tightVNC viewer to try and connect, trying both mydnsname.com:5901 and myipaddr:5901, myipaddr of course being my linux machines ip adress. No matter what I do, it always says that it cannot connect to the server.

To test the avaliability of the server to windows, I telnetted to mydnsname:5901 and received a connection successfully!

So if i can reach the server with telnet...everything should be fine, but the tightVNC viewer still says that it cannot connect to the server.

Can anyone offer any advice on how to get this running? While I am on windows at the moment, I do have ssh access to my linux machine so I can do anything that need be done immediately.

Try to VNC to ipaddress:1 rather than ipaddress:5901.
