If you are intersted in cybersecurity, penetration testing, ethical hacking, I highly recommend Backtrack 4 . To get started check their Downloads, How To, and Forums section.

You may have a difficult time configuring your wireless adapter to work with BT, it could not recognize wireless networks when I tried to use it on my HP Mini 110.... I bought a rtl8191su dongle, but after hours and hours of research I was unable to properly configure it. Thankfully, I had the opportunity to get an old Dell Inspiron 8600 from a friend, installed BT to its hard drive and BT internet/wifi connectivity worked.... Monitor mode and injection are fine...... at boot, once logged in type startx to pull up the BT GUI and then open a terminal and type /etc/init.d/networking start

If you have BT trouble browse BT forums, use your favorite search engine, or ask a friend in the know.

Feel free to post your Backtrack experiences on our new forums as well, see the menu to the left.

I will be writing more on Backtrack in the coming days.... I'm new to it too.

The Backtrack HCL helps too (Hardware Compatibility List).
