he Hackerdemia Project is a LiveCD that provides both an instructional platform (in the form of a wiki) and an attack target to practice newly acquired skills.
How to start the disk:
Boot the LiveCD on a system within your pentest lab, which needs to be configured to be in the 192.168.xxx.xxx range.
Connect to http://192.168.1.123 using a web browser (preferably in BackTrack or your favorite pentest platform)
You will be presented with a web page, which is your tutorials. All hands-on examples were created with the Hackerdemia disk as the target, so your results should exactly match those found in the tutorials.
The LiveCD configures itself to an IP address of 192.168.1.123 by default. If you want to change it, simply log in as:
...and change the ifconfig information (If you don't know what I'm talking about, go to: http://en.wikipedia.org/wiki/Ifconfig )
