The Debian Project is an association of individuals who have made common cause to create a free operating system. This operating system that we have created is called Debian.
An operating system is the set of basic programs and utilities that make your computer run. At the core of an operating system is the kernel. The kernel is the most fundamental program on the computer and does all the basic housekeeping and lets you start other programs.
Debian systems currently use the Linux kernel or the FreeBSD kernel. Linux is a piece of software started by Linus Torvalds and supported by thousands of programmers worldwide. FreeBSD is an operating system including a kernel and other software.
However, work is in progress to provide Debian for other kernels, primarily for the Hurd. The Hurd is a collection of servers that run on top of a microkernel (such as Mach) to implement different features. The Hurd is free software produced by the GNU project.
A large part of the basic tools that fill out the operating system come from the GNU project; hence the names: GNU/Linux, GNU/kFreeBSD, and GNU/Hurd. These tools are also free.
Of course, the thing that people want is application software: programs to help them get what they want to do done, from editing documents to running a business to playing games to writing more software. Debian comes with over 51000 packages (precompiled software that is bundled up in a nice format for easy installation on your machine), a package manager (APT), and other utilities that make it possible to manage thousands of packages on thousands of computers as easily as installing a single application. All of it free.
It's a bit like a tower. At the base is the kernel. On top of that are all the basic tools. Next is all the software that you run on the computer. At the top of the tower is Debian — carefully organizing and fitting everything so it all works together.
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
Cutting edge features
FreeBSD offers advanced networking, performance, security and compatibility features today which are still missing in other operating systems, even some of the best commercial ones.
Powerful Internet solutions
FreeBSD makes an ideal Internet or Intranet server. It provides robust network services under the heaviest loads and uses memory efficiently to maintain good response times for thousands of simultaneous user processes.
Advanced Embedded Platform
FreeBSD brings advanced network operating system features to appliance and embedded platforms, from higher-end Intel-based appliances to ARM, PowerPC, and MIPS hardware platforms. From mail and web appliances to routers, time servers, and wireless access points, vendors around the world rely on FreeBSD’s integrated build and cross-build environments and advanced features as the foundation for their embedded products. And the Berkeley open source license lets them decide how many of their local changes they want to contribute back.
Run a huge number of applications
With over 33,000 ported libraries and applications, FreeBSD supports applications for desktop, server, appliance, and embedded environments.
Easy to install
FreeBSD can be installed from a variety of media including CD-ROM, DVD, or directly over the network using FTP or NFS. All you need are these directions.
FreeBSD is free
While you might expect an operating system with these features to sell for a high price, FreeBSD is available free of charge and comes with the source code. If you would like to purchase or download a copy to try out, more information is available.
The OpenBSD project produces a FREE, multi-platform 4.4BSD-based UNIX-like operating system. Our efforts emphasize portability, standardization, correctness, proactive security and integrated cryptography.
- OpenBSD runs on many different hardware platforms.
- OpenBSD is thought of by many security professionals as the most secure UNIX-like operating system, as the result of a never-ending comprehensive source code security audit.
- OpenBSD is a full-featured UNIX-like operating system available in source form at no charge.
- OpenBSD integrates cutting-edge security technology suitable for building firewalls and private network services in a distributed environment.
- OpenBSD benefits from strong ongoing development in many areas, offering opportunities to work with emerging technologies with an international community of programmers and end-users.
- OpenBSD attempts to minimize the need for customization and tweaking. For the vast majority of users, OpenBSD "Just Works" on their hardware for their application. Not only is tweaking and customizing rarely needed, it is actively discouraged.
OpenBSD is excellent for servers, appliances and network equipment. When you start to appreciate the security, stability and simplicity you may be tempted to try this OS as a desktop environment which turns out to be a very pleasant experience as well. Examples of window managers in OpenBSD 6.9 are GNOME 3.38, KDE 5.80 and Xfce 4.16.
OpenBSD is also a great environment for developers. For instance Go 1.16.2, Node.js 12.16.1, GHC 8.10.3, Python 2.7.18, 3.8.8 and 3.9.2 and Ruby 2.6.7, 2.7.3 and 3.0.1 are supported in OpenBSD 6.9.
Several solutions developed by the OpenBSD project (see http://www.openbsd.org/innovations.html) has been adopted by other operating systems including OSX, Linux and Windows. OpenSSH, PF, tmux and LibreSSL are some widely adopted solutions.

Bash is the shell, or command language interpreter, that will appear in the GNU operating system. Bash is an sh-compatible shell that incorporates useful features from the Korn shell (ksh) and C shell (csh). It is intended to conform to the IEEE POSIX P1003.2/ISO 9945.2 Shell and Tools standard. It offers functional improvements over sh for both programming and interactive use. In addition, most sh scripts can be run by Bash without modification.
The improvements offered by BASH include:
- Command line editing
- Unlimited size command history
- Job Control
- Shell Functions and Aliases
- Indexed arrays of unlimited size
- Integer arithmetic in any base from two to sixty-four
The primary goal of the Network UPS Tools (NUT) project is to provide reliable monitoring of UPS and PDU hardware and ensure safe shutdowns of the systems which are connected.
OpenSSL is a framework which implements the secure socket layer. It ships with a program/library which gives you access to all those functions.

Apache, is a web server notable for playing a key role in the initial growth of the World Wide Web and in 2009 became the first web server to surpass the 100 million web site milestone. Apache was the first viable alternative to the Netscape Communications Corporation web server, and has since evolved to rival other Unix-based web servers in terms of functionality and performance. The majority of all web servers using Apache are Linux web servers. Apache is developed and maintained by an open community of developers under the auspices of the Apache Software Foundation.
GitLab is a on-premise or hosted Git repository management tool. It also includes code reviews, issue tracking, wikis, and continuous integration.
Jenkins is a fork of Hudson and is a continuous build system for software projects.
The leading open source automation server, Jenkins provides hundreds of plugins to support building, deploying and automating any project.
Jenkins is an application that monitors executions of repeated jobs, such as building a software project or jobs run by cron. Among those things, current Jenkins focuses on the following two jobs:
Building/testing software projects continuously, just like CruiseControl or DamageControl. In a nutshell, Jenkins provides an easy-to-use so-called continuous integration system, making it easier for developers to integrate changes to the project, and making it easier for users to obtain a fresh build. The automated, continuous build increases the productivity. Monitoring executions of externally-run jobs, such as cron jobs and procmail jobs, even those that are run on a remote machine. For example, with cron, all you receive is regular e-mails that capture the output, and it is up to you to look at them diligently and notice when it broke. Jenkins keeps those outputs and makes it easy for you to notice when something is wrong.
