Installing Virtual Box on Backtrack 4 R2

Lately I have had a lot of requests on how to install Sun’s Virtual Box on Backtrack 4. Virtual Box is a virtual environment similar to Vmware but it is free. Virtual Box will allow you to run other operating systems on your host. This can be useful for security because you will not harm any one or any thing will practicing.
It should be noted that adding third party repositories to any distribution can cause problems. That being said, many of us have downloaded and installed Virtual box using this method with out any problems.

Below I will outline the few simple steps to install Virtual Box

Script to Find All IP Addresses on a Internal Network

I was working on a presentation this morning and as I was writing I realized I did not have a quick fast way to make a list of all the internal Ips on a LAN (Local Area network). Many of the tools I use including nmap, nessus and nexpose will accept a list of ips so  I decided to whip up a quick dirty shell script to get the job done.  I may clean it up in the future but for now it does its job. This is meant to work on Backtrack 4 but in its current state it will work on any Debian based distro. As always with any code found on the internet you use this at your own risk. Also I am sure this can be done better but like I said it was a 10 minute fix.
