In computing, Virtual Network Computing (VNC) is a graphical desktop sharing system that uses the RFB protocol to remotely control another computer. It transmits the keyboard and mouse events from one computer to another, relaying the graphical screen updates back in the other direction, over a network.

Access KVM virtual machines over VNC without port forwarding with SSH
Is it possible to access the VMs without having to forward the remote port and VNC to the localhost? I'd like to be able to VNC into the KVM server and see the VMs display.

"Oh no! Something has gone wrong." What am I doing wrong with the default CentOS VNC configuration?
I'm trying to configure a little PC settop for work that will mostly be used as a remote backup server (basically just something that exists for the extremely remote possibility that our data center disappears in the rapture) at my employer's home.…

Can someone explain how NX works?
I can't seem to find much about how the NX protocol actually works. I have heard it does something with sending X11 commands. But does this mean that the listening clients need to have an x server to run the actual commands and display them?
