1. Python
2. AirCrack-ng
3. macchanger

What is the main point behind this post?

• The main point is this that the readers can get the basic knowledge that how can we setup and install a Linux related program. Since, in BackTrack 5 every program is pre-configured.

• Second point is this that most of the users don't use Linux primarily instead they use Windows and then setup a dual boot for Linux and Windows. But in case of Backtrack 5 the compatibility isn't assured. Also, it doesn't get at dual boot like Ubuntu instead Backtrack 5 takes some space and make it hidden. Which if user again install Windows Appears as unknown space and ultimately to that space a new partition has to be rendered. But in case of Ubuntu, it can be installed at any partition in any folder, Named as ubuntu commonly.So, ubuntu is better choice as it can be removed from programs in windows easily.

Downloading and Installing all the requirements used to run Fern in Ubuntu:-

In case of ubuntu you just have to go to Ubuntu Software Center and search the names of the requirements given above. Like Python, xterm etc. and Install them, one by one. After having all these things installed read below how to install Fern Wifi Cracker.
Over the internet you can search for wikis also in order to install these applications by terminal for installing them in any other linux version.
