How to install pentesting tools?

Question

I am learning pentesting. I don't want to install BackTrack as my main OS. Instead, I'd like to install the relevant tools on my Ubuntu 12.04 system. My understanding is that it is possible to install this software on Ubuntu, but I don't know how. How can I do this?

Answer 1

Installing Backtrack software on Ubuntu is not recommended as it can confuse or break the package manager. However, if you want to do it, open terminal and do the following:

sudo bash
echo deb http://repo.offensive-security.com/dist/bt4 binary/ >> /etc/apt/sources.list
wget http://repo.offensive-security.com/dist/bt4/binary/public-key && sudo apt-key add public-key && sudo aptitude update
for i in $(cat backtrack.txt); do sudo apt-get -y install $i; done

Now, copy the following into Gedit and save it to your home directory as bt_menu_update.pl:
