  • Kali Linux, like BackTrack, is completely free of charge and always will be. You will never, ever have to pay for Kali Linux.
  • We are committed to the open source development model and ourdevelopment tree is available for all to see. All of the source code which goes into Kali Linux is available for anyone who wants to tweak or rebuild packages to suit their specific needs.
  • Kali adheres to the Filesystem Hierarchy Standard, allowing Linux users to easily locate binaries, support files, libraries, etc.
  • A regular sticking point with Linux distributions has been supported for wireless interfaces. We have built Kali Linux to support as many wireless devices as we possibly can, allowing it to run properly on a wide variety of hardware and making it compatible with numerous USB and other wireless devices.
  • The Kali Linux team is made up of a small group of individuals who are the only ones trusted to commit packages and interact with the repositories, all of which is done using multiple secure protocols.Every package in Kali Linux is signed by each individual developer who built and committed it, and the repositories subsequently sign the packages as well.
  •  Although penetration tools tend to be written in English, we have ensured that Kali includes true multilingual support, allowing more users to operate in their native language and locate the tools they need for the job.
  •  Since ARM-based single-board systems like the Raspberry Pi and BeagleBone Black, among others, are becoming more and more prevalent and inexpensive, we knew that Kali’s ARM support would need to be as robust as we could manage, with fully working installations for both ARMEL and ARMHF systems. Kali Linux is available on a wide range of ARM devices and has ARM repositories integrated with the mainline distribution so tools for ARM are updated in conjunction with the rest of the distribution.

Steam OS; Next segment of gaming


SteamOS, Valve’s specialized gaming operating system, is gearing up for a full release, and should be widely available before the end of the year. The developing OS is a curious beast: It’s optimized for PC gaming but doesn’t run some of the most popular PC games. It is a Linux-based operating system developed by Valve. The software highlights PC gaming but will also have access to streaming video, music and other online services.

You must be thinking why would you run it. It will be very lightweight, and is designed specifically with big-screen TVs in mind. It aims to split the difference between customizable PC gaming and comfortable console gaming. Hooking a SteamOS machine up to your TV may be easier than hooking up a Windows PC or Mac. Because many Steam games allow you to use a controller instead of a mouse and keyboard, a SteamOS system can offer you hundreds of the industry’s most popular games at lower prices.

Any Steam game with Linux support should run on SteamOS, although Valve will pin down this list as the official launch date approaches. There are roughly 2,000 Linux games available through Steam, including major titles like Counter-Strike: Global Offensive and indie darlings like Hotline Miami and Generally speaking, games that are compatible only with Windows and Mac will not run on SteamOS. The list of games that do not run on Linux is extensive: Series such as BioShock, Grand Theft Auto and Call of Duty currently have no Linux support on Steam.

Valve does not produce any Steam machines; instead, it has collaborated with a number of partners to offer a full range of gaming PCs, from the budget-minded to the fantastically powerful. SteamOS is available free of charge. Steam Machines range from $460 to $5,000. You can also find a machine to fit your exact budget by constructing it yourself.


There is a Steam controller valve designed the Steam Controller from the ground up, to get the most out of Steam titles without resorting to a mouse and keyboard. However, the controller is not necessary; gamers can still use a mouse and keyboard, or another type of controller, if they prefer. For full impressions on the Steam Controller, check out our hands-on.

Five Things You Didn’t Know about Linux

  • Image Editing & Processing

download (13)

  • You probably know that a Mac is the device of choice for digital artists and graphic designers around the world, although you’ll probably be surprised to find that a big chunk use Windows. What unifies these talented creators of art and design is their reliance on Adobe’s Photoshop and Illustrator applications, which are sadly unavailable on Linux (unless you plan to run them in Wine).
  • Fortunately, Linux users who are aspiring and working artists don’t have to end their ambitions there. Our recent look at Photoshop alternatives for Linux will give you a good idea of what you can do with open source alternatives, most of which run on Linux. In a nutshell, it’s virtually everything that you can do on a Mac or PC!


  • Even Edit Video on Linux

download (12)


  • Windows users with digital video cameras will know how tricky it is to find good quality video editing software. While Windows Movie Maker was once a good choice, the world has moved on. But do you really want to migrate to Linux and find that there is no alternative to something like Adobe Premiere?
  • No, of course not. But fortunately, there are alternatives. If you haven’t already heard of Lightworks, this is just one of a handful of good quality applications. We reckon that PiTiVi is another good option for Linux users, offering basic editing tools, effects, but Kdenlive remains the best video editing software on Linux.


  • Record and Edit Audio

  • Whether you’re editing a podcast or recording your band’s next great record, audio editing support is a massive advantage (unless you prefer recording live). But does Linux offer this support?
  • If you’re editing audio on Windows, there is a very good chance that you’re using the versatile open source Audacity suite, and this is available on Linux. While it doesn’t offer the full suite of tools you might expect from pro applications, Audacity is good enough for most tasks.
  • For those Linux-based audio editing projects that can’t be completed with Audacity, meanwhile, take a look at apps such as Linux Multimedia Studio (LMMS) which we’ve summarized previously.


  • Need to Run Windows?
  • In the event that you have migrated – or are planning to – from Windows and suddenly need to switch back to your original operating system, using a dual boot setup is a good idea (although sharing data between platforms can be frustrating).
  • But if you’re using a suitable machine (and this is pretty much anything with an Intel Core i5 CPU or higher) then virtualization technology will allow you to run Windows within Linux. To do this you’ll need to install a virtual machine application such as Oracle VM VirtualBox, although there are alternatives in the shape of VMWare and QEMU, which is used by the Gnome Boxes tool.
  • These tools provide a software environment that mimics hardware, enabling you to install Windows within Linux. This can prove extremely useful if you have to use Windows for a particular task but don’t want to stop what you’re doing in Linux to switch devices or reboot – it’s there on your desktop as an option for you to launch as and when. A virtual machine can also keep your Linux environment and your PC safe from Windows-based threats.


  • Can’t play games on Linux? Think again.

  • While the early days of Linux gaming was limited to independent titles and open source ports of well-known Windows games (like FreeCol, a Colonization clone and OpenTTD, which owes an awful lot to Transport Tycoon) times have changed considerably.
  • For low end machines, the open source options remain, as do various Linux-only titles and browser games. But if you’re rocking some high end hardware, you would do well to install Steam on Linux and start enjoying some of the games you originally played on Windows.


These Cloud Computing Skills Could Give You The Next Career Jump


  • At the end of last year, there were over 3.9 million jobs in the cloud computing field in America alone—and over 18 million around the world. And professionals with cloud computing experience took home a median salary of over $90,000.
  • It’s a great field to get into — but what skills do you need for a job in cloud computing? Any expertise in these 9 areas will help set you apart from the rest of the application pile.


  • Database Skills
  • Because cloud computing so often deals with large databases of information, being able to understand and work with database languages is crucial. SQL and MySQLare the de facto standard languages for databases, but being familiar with open-source systems like Hadoop, Cassandra, and MongoDB is also helpful.
  • If you’re looking for a more fun way to learn some database skills, you can check out Schemaverse, a space-based strategy game in which players use SQL commands to control their fleets. GalaXQL is another great resource for learning to work with databases — the interactive app lets you practice your SQL queries and guides you along the way.


  • Linux
  • The Linux operating system dominates a large portion of the cloud computing world, so being familiar with it will give you a big headstart on many of your potential competitors. A good first step is to set up your computer to dual-boot with your preferred operating system (we have tutorials for dual-booting Windowsas well as OS X).


  • DevOps


  • Development operations is a particular method of software development that takes the entire software lifecycle into account, from planning and prototyping to use and maintenance. DevOps is very popular in cloud computing, so understanding what it is and how you fit into it can be a big help.
  • You can start learning about DevOps by going to and reading their articles to get an idea of the sorts of issues at stake. Microsoft Virtual Academy provides an overview of DevOps, and Linux academy has a short DevOps course that will be helpful, as well.


  • Systems Automation

  • As companies are storing and using more and more information all the time, working with it manually and on a project-to-project basis is becoming unsustainable. Developers who can automate tasks and processes are highly valuable, as they can significantly improve the efficiency of a company’s interactions with data.
  • While “automation” is a relatively vague term, you can gain skills in this area by learning about Puppet and Chef, two open-source automation solutions.
  • Puppet Labs offers a range of learning options, from live courses and certifications to self-paced online learning. It is also cross-platform.
  • Chef is another systems and cloud infrastructure automation tool with a number of interactive learning modules.


  • Quality Assurance
  • According to a 2014 survey by Forbes, software quality assurance was the sixth-most common request in cloud computing job postings. In short, software QA is the process by which developers and other producers make sure that the software they produce meets the needs that it sets out to and that it’s of acceptable quality upon release.


  • Information Security
  • The Certified Information Systems Security Professional (CISSP) certification is one of the most requested certifications in the cloud computing world. This certification is bestowed by International Information System Security Certification Consortium, Inc, and the exam covers knowledge on things like asset security, identity and access management, and software development security.


  • Project Management
  • The Project Management Professional certification is highly recognized and respected within the industry. If you have a few years of experience in project management, you may be eligible for this certification; if not, you may be eligible for the Certified Associate in Project Management certification.
  • To find out more about the PMP certification, you can visit the Project Management Institute website and read about their various certifications. There are also a number of other certifications that may be of interest, such as one in program management, and another in business analysis.


  • Amazon and Google Cloud Skills

  • Being familiar with specific vendors of cloud solutions can be a big help if a potential employer already works with those companies. Because Amazon and Google cloud platforms are so popular (even the NSA uses Amazon Web Services), having some familiarity with these technologies can give you a boost in the hiring process.


  • The Future Is in the Cloud

download (11)

  • Many businesses are quickly transitioning a lot of their computing and data storage to the cloud, and there’s a big need for developers and other technical employees to help them with the process. Whether you’re a cloud expert or a total beginner, this is a great field to get into. Start polishing your skills!


All about Linux Servers for Small Business

  • Linux powers everything from humble, small business servers to Amazon, Facebook, Google, and the London Stock Exchange. Linux servers offer all the flexibility and power you’ll ever need. In this roundup we’ll look at some of the best general-purpose Linux servers for your small business.
  • All of the Linux small business servers mentioned here run well on modest hardware, plus, they’re reliable, stable and secure. You get a complete range of functionality, including essential services, networking and security.
  • Windows_Vs_Mac_Vs_Linux_10
  • 1. ClearOS
  • ClearOS, which used to be called Clark Connect, is an integrated network, gateway, and server platform that bundles a wealth of useful features behind a well-organized browser-based administration interface. You get Web, print, messaging and file servers; networking and Internet gateway; VPN; sophisticated user- and resource-management; network charting; databases; and much more.
  • ClearOS has one of the best administration interfaces and superior documentation, so it’s a good fit for less-experienced admins or admins who just want to get up and running without a lot of fuss.

  • 2. Ubuntu Server
  • If you follow Linux news at all, you know that Ubuntu gets a lot of attention, both positive and negative. If you put five Linux fans together in a room, you’ll have a hundred opinions and no agreement on anything, so don’t let geek controversies bother you. It’s what we do.
  • Ubuntu Server is a serious server operating system for small businesses that have a good system and network administrator.
  • Ubuntu is the #1 in the Linux desktop market and some use Ubuntu for the servers also. Ubuntu offers the following three editions.
  • 1. Ubuntu Desktop Edition
  • 2. Ubuntu Server Edition
  • 3. Ubuntu Notebook Remix

  • 3. Red Hat Enterprise Linux
  • Red Hat Enterprise Linux (RHEL) is the top dog in commercial Linux distributions. It has first-rate support and services, and provides rock-solid dependability. SUSE Enterprise Linux. If an organization doesn’t mind spending dollars on purchasing the red-hat support, this is always my #1 recommendation to any organization who runs mission critical applications.
  • On a side note, one of the reason I like Red Hat Linux for mission critical production application is that Red Hat tends to take some of the new features from Fedora, which is well tested by the community.
  • images
  • 4.  SUSE Enterprise Linux
  • SUSE Enterprise Linux is the other big Linux name. SUSE, like RHEL, is a first-rate business operating system that won’t let you down. Priced similarly to RHEL, SUSE also offers great documentation and excellent management tools. SUSE offers one product that RHEL doesn’t: a point-of-service edition for retailers. It’s affordable even for a small shop, though the real cost of any POS is integrating it with your products and inventory, and keeping it updated.If you don’t need all that fancy stuff, SUSE Enterprise Linux is still an excellent general-purpose LAN server.
  • Suse-Logo-580x224_tcm21-102997


  • 5. Debian and CentOS
  • There is a tie for the fifth spot in our roundup: Debian and CentOS Linux. These are my picks for the experienced Linux admin who doesn’t need commercial support or a lot of bells and whistles. Both are lean and efficient, and completely customizable to suit your needs. Both have good community support and a wealth of documentation.
  • Debian, like Red Hat, is one of the foundation Linux distributions. Unlike Red Hat, Debian is completely community-maintained and has no commercial interests. Debian and Red Hat represent both sides of Linux and open source.
  • A clone of Red Hat Enterprise Linux, CentOS usually runs a few weeks behind RHEL releases, all the Red Hat branding has been removed, and it cannot use Red Hat services like Red Hat Network. Security patches and updates are timely, and the excellent Red Hat manuals work fine with CentOS.
