Setting up X11 tunneling

Setting up X11 tunneling

First of all make sure that you have a recent version of PuTTY which supports X11 tunneling. You can get it from this page.

It is now time to bring up PuTTY, so do so! Select the category "Connection/SSH/Tunnels". Check the "Enable X11 forwarding" box and fill out the text field below with the address of your X11 server. The format is either "IP address:display" or "host name:display". You will most likely be using display 0 (zero), but you will probably know if not. If your X11 server is not running on the local computer, you must be able to trust the network between your local machine and your X11 server. If your X11 server runs on the same computer as PuTTY, put "127.0.0.1:0" in the text box.
