This is a HOWTO for setting up SSH tunneling between PresenceVNC and x11vnc server. For more general usage instructions, see the [http://presencevnc.garage.maemo.org/ PresenceVNC Home Page].

=== Step 1 (setting up) ===
 +
----

Install an SSH-server and x11vnc on your home computer and an SSH-client on your n900. If you have a router you need to port forward port 22. Normaly you can login on the router using your browser. Just write the adress "192.168.1.1" in the adress field. You also need to allow port 22 on your firewall (i used Firestarter for that).

Put the files in "<code>/home/<user>/.ssh/</code>". Change "<code><user></code>" to the one on your home computer. One will be named "<code>id_dsa</code>" and the other "id_dsa.pub". You will probably have to make the folder "<code>/home/user/.ssh/</code>" on your N900.

Write your home computers password when it is asking. It is not necessary to use "-C" but I recommend it. It will compress the stream and make it go smoother on a 3G connection. The "user" is the user and "ip-number" the ip-number of your home computer. You could use a dynamic ip-number provider.. like http://www.no-ip.com.

Now you have connected your home computers port 5900 to the N900 port 5900. This is also known as "tunneling". And are currently logged in on your home computer.
