Virtual Network Computing

Virtual Network Computing, or VNC, is a tool for remote desktop sharing. Client and server programs are available on most operating systems. Some windows clients can be installed without administrator privileges. VNC has trouble passing firewalls.

When using VNC, it is often easier to have the server connect to the client instead of the other way around. The instructions for servers below are written in this way.
