If you’ve ever wanted to have your Windows accessed from abroad and don’t have a second Windows machine you can do so e.g. running
rdesktop on a Linux machine to connect to an installation of a (Windows based) VNC Server like Tight VNC or Real VNC (both free of charge). Get instructions from ubuntuforums.org kindly written by Bazon. If I have time I might do a picture comic for Feisty since the thread is about one year old.
Update: There also is a package/front-end called Gnome-RDP that includes ssh-connectivity, too. If you’re not concerned about security it totally works by running the installer of Tight VNC on the Windows machine (just confirm every default setting, i.e. run the server as Windows background service) and use Gnome-RDP to directly connect to the IP of the Windows machine. Alternatively, it supports RDP (as the name suggests). So if the Windows machine is configured to accept remote desktop connections (see below; plus you need to “Select Remote Users…”. Get hold of the dialog by Start -> right-click “My Computer” -> Properties -> “Remote” Tab) it’s just as if you were connecting from a second MS computer. If you happen to have your windows seesion in fullscreen and want to get back to Linux hit Ctrl+Alt+Enter (Return).
Of course, if you leave your cosy home LAN or a likewise basically secure network, you’d need to install an ssh server on the Windows machine and let VNC only accept local connections.
