I booted the VA using the Ubuntu Live CD and opened a Terminal. Then I used the cfdisk tool (sudo cfdisk /dev/sda) to view the partitions:

Note that I am using my own Access Point here so I am not actually cracking someone else’s WEP Key.

Requirements:

• back|track Linux distribution
• USB WiFi card (most internal WiFi cards will not work)

In this post I am using the 32 bit back|track 5 VMWare image which you can use with VMWare Workstation or VMWare player.

After starting the back track Virtual Machine you can login with username root and password toor

The install is unattended (when VMWare Tools are installed you need to perform a login) and took only 6 minutes on my laptop!

Now we need to install gcc (the compiler), open the Ubuntu Software Center:
