The Birth of Kali Linux

“From the creators of BackTrack comes Kali Linux, the most advanced and versatile penetration testing distribution ever created.”

Kali Linux is a successor of BackTrack, an opensource linux distribution for security researchers.

The most obvious changes are Kali Linux is now based on Debian and a FHS-Compliant system.

In BackTrack, when you open a tool, it opens in a /pentest directory where almost all security tools are located and will not run if you just call it from any directory. In FHS-Compliant system, you do not have to go through /pentest directory but rather just call the tool from your terminal even you’re in a different directory tree.
