The Future Belongs to Linux/Unix
In this post we will tell about some Basics in Linux.This might seem like a radical statement, but I firmly believe that the future of data technology belongs to Linux and Unix systems. Microsoft had its day in the 1980s and 1990s, but its growth is slowing and stagnating.
Since the web began, Linux/Unix has been the OS of choice for web servers thanks to its stability, reliability, and robustness. Even today, Linux/Unix is utilized in twothirds of web servers and dominates the market.
Embedded systems in routers, switches, and other devices almost always use a Linux kernel, and the world of virtualization is dominated by Linux, with both VMware and Citrix built on the Linux kernel.
Over 80 percent of mobile devices run Unix or Linux (iOS is Unix, and Android is Linux), so if you think that the longer term of computing lies in mobile devices like tablets and phones (it would be hard to argue otherwise), then the longer term is Unix/Linux.
Microsoft Windows has just 7 percent of the mobile devices market. Is that the wagon you would like to be hitched to?
DOWNLOADING KALI LINUX
Before getting started, you need to download and install Kali Linux on your computer. This is the Linux distribution we’ll be working with throughout this book. Linux was first developed by Linus Torvalds in 1991 as an open source alternative to Unix.
Since it’s open source, volunteer developers code the kernel, the utilities, and the applications.
This means that there is no overriding corporate entity overseeing development, and as a result, conventions and standardization are often lacking.
Kali Linux was developed by Offensive Security as a hacking OS built on a distribution of Linux called Debian. There are many distributions of Linux, and Debian is one among the simplest. You are probably most conversant in Ubuntu as a well-liked desktop distribution of Linux. Ubuntu is also built on Debian.
Other distributionsinclude Red Hat, CentOS, Mint, Arch, and SUSE.Although a l of them share an equivalent Linux kernel (the heart of the OS that controls the CPU, RAM, then on), each has its own utilities, applications, and choice of graphical interface (GNOME, KDE, and others) for various purposes. As a result, each of these distributions of Linux looks and feels slightly different.
For instance, the primary image name listing I see is Kali Linux 64 Bit, meaning it’s the complete Kali Linux and is suitable for 64bit systems—most modern systems use a 64bit Intel or AMD CPU.
To determine what type of CPU is on your system, go to Control Panel System and Security System, and it should be listed. If your system is 64bit, download and install the 64 bit version of the full Kali (not Light or Lxde, or any of the other alternatives). If you are running an older computer with a 32bit CPU, you will need to install the 32 bit version, which appears lower on the page. You have a choice of downloading via HTTP or Torrent.
If you choose HTTP, Kali will download directly to your system just like any download, and it will be placed in your Downloads folder. The torrent download is the peertopeer download used by many filesharing sites. You will need a torrenting application like BitTorrent to do this. The Kali file will then download to the folder during which the torrenting application stores its downloads.
After download kali Linux
There are other versions for other sorts of CPUs, like the commonly used ARM architecture found in numerous mobile devices. If you are using a Raspberry Pi,tablet, or other mobile device (phone users wi l likely prefer Kali NetHunter), make certain you download and insta l the ARM architecture version of Kali by scroling right down to Download ARM images and clicking Kali ARM Images.
