ADB in Ubuntu 10.10

[lemeiux1]

Ok so I'd really like to get adb up and running on my linux machine as I use ubuntu a lot more than windows (and am really thinking about completely replacing it altogether) but I cant find a tutorial on how to do this as they are all for windows. I tried following this guide: [GUIDE] Lazyman's installation guide to ADB on Ubuntu 10.10 - xda-developers but I get stuck at the part about permissions (shows adb device-> Permissions ??????? no matter what I do)

can anyone walk me through it or know of a guide I can use?

thanks a lot
