![]() ![]() One of the programmers assigned to the project from Bell Labs returned to his regular job and eventually decided to write his own version of an operating system in order to play a game he had originally written for Multics but wanted to play on a PDP-7 that was available at Bell Labs. Inevitably, the project slowly fell apart, though the operating system was eventually released. Having a system that could support only a single user at a time was just not cost-effective-thus the development of Multics by MIT, Bell Labs, and GE was a way of making computers more cost-effective. As a point of comparison, a $7 million system today (at the time of this writing, in late 2017) would have cost about $44 million then. At a minimum, computer hardware was hundreds of thousands of dollars. After all, this was an era when the computer hardware necessary to run operating systems like Multics ran into the millions of dollars. The goal of Multics was to support multiple users and offer compartmentalization of processes and files on a per user basis. Once upon a time, back in the days of the dinosaur, there existed an operating system called Multics. ![]() Understanding this history will help provide some context for why Linux is the way it is-especially the seemingly arcane commands that are used to manage the system, manipulate files, and just get work done. Linux actually has a long history, if you trace it back to its beginnings. Using Linux is all about making the system work for you, rather than having the system force the way you work because of how it works, looks, and feels. Even beyond that, you can change the look of each of those things. This includes the shell in which you type commands and the graphical desktop you use. One of the really nice things about Linux, especially as compared to other operating systems, is that it is almost completely customizable. In the case of Kali, what gets layered on are not only the essential utilities, but also hundreds of software packages that are specific to security work. Each distribution layers additional software on top of that core, making it unique. Linux is really just the kernel-the actual operating system and the core of the distribution. The thing about Linux distributions is that they aren’t the same. This may be security testing, it may be exploit development or reverse engineering, or it may be digital forensics. It is targeted at people who want to engage in security work. More users would be happier with Ubuntu (which I also have here on this X1).Kali Linux is a specialized distribution of the Linux operating system. I do not know if Kali is really widespread. See if your ThinkPad has and supports Hyper-V and you can download and install Kali 2020.4 for free to see what it is about. I have Kali in VMware on my X1 and in Hyper-V on my X230. If you wish to learn it before committing a machine to its use, you might be better off to install in in a Virtual Machine. I have a Lenovo-ThinkPad laptop and tried downloading it but it didn't I think there may be USB wireless cards that might work. Your ThinkPad likely does not have such wireless - my ThinkPad X1 and X230 do not. I have Kali in a Virtual Machine to learn it, and I am in Kali as I post this.įor true penetration testing, it is best installed on a physical machine and then you need a wireless adapter that can use promiscuous mode. Kali can always be updated to the newest version without Well as a number of specialized builds for many popular hardware Available in 32 bit, 64 bit, and ARM flavors, as Download Kali Linux – our most advanced penetration testing platform ![]()
