Download Ubuntu 11.04 for Free

The release of Ubuntu 11.04 has seen the arrival of a new look and feel for Ubuntu. A whizzy, new launcher and dash, and a clever workspace manager are some of the biggest changes. Take a look at what’s new and then feel free to choose between the classic and new desktop experiences at login.

The launcher

It’s pretty hard to miss the new launcher that sits on the left-hand side of your screen. It’s designed to make getting to your favourite tools and applications quick and easy. You can hide and reveal it in the top-left corner of your screen, add and remove applications and bookmarks, and keep track of your open windows.

The dash

When you click on the Ubuntu logo in the top-left corner of your screen, the new dash will appear. It’s another simple way to get to your shortcuts and search for other applications and programs. So you can get fast access to your email, music, pictures and much more.

Workspaces

Ubuntu 11.04 gives you a really easy way to manage multiple windows and applications. Simply click on the Workspaces icon in the launcher and all your active spaces will pop up. You can move between your different windows easily so there’ll be no more cramping multiple apps into a small space.

free download backtrack Operating system.

 

 BackTrack is the most top rated linux live distribution focused on penetration testing. With no installation whatsoever, the analysis platform is started directly from the CD-Rom and is fully accessible within minutes.

It's evolved from the merge of the two wide spread distributions - Whax and Auditor Security Collection. By joining forces and replacing these distributions, BackTrack has gained massive popularity and was voted in 2006 as the #1 Security Live Distribution by insecure.org. Security professionals as well as new-comers are using BackTrack as their favorite toolset all over the globe.

BackTrack has a long history and was based on many different linux distributions until it is now based on a Slackware linux distribution and the corresponding live-CD scripts by Tomas M. (www.slax.org) . Every package, kernel configuration and script is optimized to be used by security penetration testers. Patches and automation have been added, applied or developed to provide a neat and ready-to-go environment.

After coming into a stable development procedure during the last releases and consolidating feedbacks and addition, the team was focused to support more and newer hardware as well as provide more flexibility and modularity by restructuring the build and maintenance processes. With the current version, most applications are built as individual modules which help to speed up the maintenance releases and fixes.

Because Metasploit is one of the key tools for most analysts it is tightly integrated into BackTrack and both projects collaborate together to always provide an on-the-edge implementation of Metasploit within the BackTrack CD-Rom images or the upcoming remote-exploit.org distributed and maintained virtualization images (like VMWare images appliances).

Being superior while staying easy to use is key to a good security live cd. We took things a step further and aligned BackTrack to penetration testing methodologies and assessment frameworks (ISSAF and OSSTMM). This will help our professional users during their daily reporting nightmares.

Currently BackTrack consists of more than 300 different up-to-date tools which are logically structured according to the work flow of security professionals. This structure allows even newcomers to find the related tools to a certain task to be accomplished. New technologies and testing techniques are merged into BackTrack as soon as possible to keep it up-to-date.

No other commercial or freely available analysis platform offers an equivalent level of usability with automatic configuration and focus on penetration testing.
