Maybe everyone want to be the trained user. This is for everyone that want to be a network security.
I found this on kaskus.us. The forum said that if you want to be a "gray hat" or a network security, you do not have to use the Penetrated Distribution. You can do it with your Ubuntu.
First, you must download the key. Backtrack.gpg
Then, open your terminal and write this
wget -q http://archive.offensive-security.com/backtrack.gpg -O- | sudo apt-key add -ok-
This command is used for add the BackTrack key. BackTrack is included in the Penetration Distribution.
Open your sources.list, and add this repository
deb http://archive.offensive-security.com pwnsauce main microverse macroverse restricted universe multiverse
Then type this:
urname@urcomputer:~$ sudo apt-get update
I've try it. But I fail. Here I use UNE (Ubuntu Netbook Edition) Lucid Lynx.
If the lucky in your side, the synaptic will show the penetration utility.
