I have been working on some machines using Windows and the commercial X-server for Windows called X-Win32. It irritated me however to know that the users was paying a license fee to use the program, since it possible to do the same with a open source VNC client, as TightVNC. In the following I will use the name bohr as the hostname for my server and dirac as the name of the client connecting to server bohr.
Every interesting blog article has a illustration – this is a ssh tunnel transporting VNC data through the unsecure Internet. Made with Dia.
