I'm a Linux newbie but trying to learn fast - so if anyone can give me a bit of help it would be much appreciated...

I'm trying to install OpenVPN on my N800, with the intention ultimately of being able to connect to the OpenVPN server on my desktop machine.

The ApplicationsCatalog2006 at maemo says that the OpenVPN port has been tested and works on the N800, and has a link to a site:
http://guerby.org/ftp/nokia800-deb/
The install instructions say to install the openvpn2.0 deb file, and a supporting liblzo1 deb file, and also to copy an openvpn file to a specific directory.

But how do I install these two deb files? I have looked on the forums and tried using "Install from file" in the download manager, but this just says the two deb files are "incompatible appication packages".

is there a way of doing this from the command shell. If so, what are the commands I need to install the two deb files? Presumably I can copy the other file to the specified location using the mv command?

Sorry for such basic questions but I am trying to get started with the N800 and learn Linux from a book. It's great to be able to ask real people for help too....

Any other OpenVPN tips greatly appreciated too!
