I'm running Ubuntu 6.06 on my system. I'm planning to run x11vnc along with Ubuntu 6.06. Now, the problem is that when i try to run x11vnc on my pc, it shows me that all all ports are closed on my system. So, i would like to know that how do i open port 25 on my Ubuntu? Does any body knows about it? Kindly provide me the correct logical solution on the above issue.
