It is a quick attempt to cover the most commonly asked questions about BackTrack, 

in one place. Check on this page frequently for updates. 

Introduction 

BackTrack  is  the  world’s  leading  penetration  testing  and  information  security 

auditing distribution.  With hundreds of tools preinstalled and configured to run out 

of  the  box, BackTrack  4  provides  a  solid  Penetration  testing  platform    ‐  from Web 

application Hacking to RFID auditing – its all working in once place. 

Behind the curtains 

BackTrack Base 

There  have  been  many  changes  introduced  into  BackTrack  4  ‐  most  notably,  our 

move  to an Ubuntu  Intrepid base. We now maintain our own  full repositories with 

modified Ubuntu packages in addition to our own penetration testing tools.  

Another significant change is the updated kernel version, currently at 2.6.29.4. This 

new  kernel  brought  an  onset  of  internal  changes, which  have  greatly  changed  the 

structure of BackTrack. 

BackTrack Kernel 

We no  longer use  lzma enabled squashfs as our  live  filesystem, which on one hand 

results  in  larger  ISO  size,  but  on  the  other  hand,  frees  us  from  having  to maintain 

our own kernel patches. This  is especially painful  these days, as  squashfs  is  slowly 

moving into the mainstream kernel (at the time of this writing). 

BackTrack  4  uses  squashfs‐tools  version  4.0  (which  is  not  backward  compatible 

with previous versions), and the inbuilt squashfs kernel module, which is present in 

2.6.29.4. AUFS is used as the unification filesystem (aufs2.x). 

Several  wireless  driver  injection/optimization  patches  have  been  applied  to  the 

kernel,  as  well  as  a  bootsplash  patch.  These  patches  can  be  found  in  the  kernel 

sources package (/usr/src/linux/patches). 

These  changes  mean  that  much  of  what  you  were  used  to  in  BackTrack  2/3  has 

changed in terms of boot cheatcodes and such, as this kernel shift also means we no 

longer use the  livelinux  scripts to create our images (we use casper now). 

 Packages and Repositories 

One of  the most  significant  changes  introduced  in BackTrack 4  are  the Debian  like 

repositories  available,  which  are  frequently  updated  with  security  fixes  and  new 

tools. This means that if you choose to install BackTrack to disk, you will be able to 

get package maintenance and updates by using  aptget  commands. 

Our  BackTrack  tools  are  arranged  by  parent  categories.  These  are  the  categories 

that currently exist: 

• BackTrack ‐ Enumeration 

• BackTrack ‐ Tunneling 

• BackTrack ‐ Bruteforce 

• BackTrack ‐ Spoofing 

• BackTrack ‐ Passwords 

• BackTrack ‐ Wireless 

• BackTrack ‐ Discovery 

• BackTrack ‐ Cisco 

• BackTrack – Web Applications 

• BackTrack ‐ Forensics 

• BackTrack ‐ Fuzzers 

• BackTrack ‐ Bluetooth 

• BackTrack ‐ Misc 

• BackTrack ‐ Sniffers 

• BackTrack ‐ VOIP 

• BackTrack ‐ Debuggers 

• BackTrack ‐ Penetration 

• BackTrack ‐ Database 

• BackTrack ‐ RFID 

• BackTrack – Python 

• BackTrack – Drivers 

• BackTrack ‐ GPU 

Meta packages 

A nice  feature  that  arises  from  the  tool  categorization,  is  that we  can now  support 

“ BackTrack  meta  packages ”.  A  meta  package  is  a  dummy  package  which  includes 

several  other  packages.  For  example,  the  meta  package “ backtrackweb ”  would 

include all the Web Application penetration testing tools BackTrack has to offer. 

Meta Meta Packages 

We have two “ meta meta packages ” –  backtrackworld  and  backtrackdesktop .  

backtrackworld   contains  all  the  BackTrack  meta  packages,  while  backtrack

desktop   contains  backtrackworld ,  backtracknetworking   and  backtrack

multimedia .  The  latter  two  meta  packages  are  select  applications  imported  from 

Ubuntu repositories.  

Up and running with BackTrack 

We’ve made a short movie called “up and running with BackTrack” – showing some 

common  and  not  so  common  features.  A  good  place  to  start  in  order  to  grasp  the 

new changes in BackTrack 4.

and‐running‐backtrack.html  

Installing BackTrack to Disk 

BackTrack  4  (both  barebones  and  full  version)  now  contains  a  modified  Ubiquity 

installer.  The install should be straight and simple. For a video tutorial, check  

http://www.offensive‐security.com/videos/install‐backtrack‐hard‐disk/install‐

backtrack‐hard‐disk.html  

Updating Backtrack 

Keeping BackTrack up to date is relatively simple by using the apt‐get commands. 

aptget update  synchronizes  your package list with our repository. 

aptget upgrade  downloads and installs all the updates available. 

aptget distupgrade  downloads and installs all new upgrades.
