I've been interested in trying out BackTrack for a while, but I'm not sure how to use most of the tools. I know there's a lot there, but is there a simple, graphical way to monitor activity on my wireless network? Instructions would be much appreciated.
Backtrack is a funny one. It certainly has a lot of tools in one place but you still need to be running compatible hardware to use them (particularly wireless tools).
I would strongly recommend doing some of the tutorials and installing the programmes you need on a dedicated linux computer as you need them.
Understanding how to install & use the tools is the important thing.
Most of the techniques rely on having multiple terminals open and either scanning/spoofing/injecting or recording packets of information.
There is very rarely a 'one click hack'
Have a look at the WEP hacking tutorials here http://www.aircrack-ng.org/doku.php
Maybe have a look at installing Debian on an old laptop http://debian.org/CD/netinst/
It's all good fun anyway.
