FreeBSD is an operating system created to be fast and secure, powering modern servers, desktops, and embedded systems. This operating system is based on U.C. Berkeley’s “4.4BSD-Lite” release, with some “4.4BSD-Lite2” enhancements. This article will recommend the best available books that will help you learn and understand the key concepts and internals of FreeBSD Unix operating system.
FreeBSD adoption is widely witnessed in these sectors – Internet Service Providers, Private companies, researchers, Computer professionals, Students and among other internet facing solutions that demands for high availability, reliability and top-notch performance. FreeBSD is also used by a number of home users all over the world in their work, education and recreation.
FreeBSD Applications Support
FreeBSD is designed to provide your favorite applications with a robust and full-featured environment. A wide variety of applications are supported on FreeBSD, example: office suites, web browsers, command line administration tools, graphics programs, email readers, programming environments, network servers, and many more.
The standard way of installation Desktop and all other applications on FreeBSD is through Ports Collection.
Versions of FreeBSD
There are two standard release of FreeBSD available to end users:
FreeBSD-STABLE
This is the development branch from which major releases are made. The packages that land here have been thoroughly tested on the CURRENT release and bugs fixed. As of this article update, the latest release form the 12-STABLE branch is version 12.1 , released in November 2019. For the 11-STABLE branch, it is version 11.3 released in July 2019.
FreeBSD-CURRENT
FreeBSD-CURRENT is the “bleeding edge” of FreeBSD development. The users of FreeBSD-CURRENT are expected to have a high degree of technical skill. If you’re a less technical user, consider using the FreeBSD-STABLE instead.
This release contains the latest source code for FreeBSD and includes works in progress, experimental changes, and transitional mechanisms that might or might not be present in the next official release.
How to Learn and Master FreeBSD
To easiest way to learn any technology or system is by consistent experimentation. I recommend you install FreeBSD OS, play with it while building Labs for different use cases. By getting a good book to complement the process, a much shorter time will be required to become a master.
Below is a list of books that I’ll recommend for users who want to master the FreeBSD Operating System.

2. The Design and Implementation of the FreeBSD
This is a book offering by Marshall Kirk McKusick. This book covers the new topics in FreeBSD up to 11. You can use this guide as both a working reference and an in-depth study of a leading contemporary, portable, open-source operating system:
- Explains highly scalable and lightweight virtualization using FreeBSD jails, and virtual-machine acceleration with Xen and Virtio device paravirtualization
- Describes new security features such as Capsicum sandboxing and GELI cryptographic disk protection
- Fully covers NFSv4 and Open Solaris ZFS support
- Introduces FreeBSD’s enhanced volume management and new journaled soft updates
- Explains DTrace’s fine-grained process of debugging/profiling
- Reflects major improvements to networking, wireless, and USB support
3. FreeBSD Mastery: Jails (IT Mastery)
Jails is one of the legendary features of FreeBSD. It is known to be a powerful and a bit tricky to master the concept. The skill of deploying Jails is required of every system admin.
This guide will walk you through Jails mastery, disclosing the inner mechanisms and unleashing their power in your service. By reading this guide to the end, you will learn:
- How Jails Achieve Lightweight Virtualization
- Detailed understanding of the base system’s jail tools and the iocage toolkit
- How to configure jail hardware
- How to manage Jails from the host and from within the Jail
- How to work within the limits of jails comfortably
- How to build virtual networks
- Implement fine-grained control of jail features

4. FreeBSD Device Drivers: A Guide for the Intrepid
Drivers are very useful for any system as they make it possible for the software to communicate with the hardware components. When developing FreeBSD, it is vital to dig and find the required Kernel content to write the required drivers. Thanks to the author of this handbook Joseph Kong, for eliminating this tussle!
Now you can use this guide to master all that is required from the basics of building and running loadable kernel modules to more complicated topics like thread synchronization. In this guide, the author explains all the basics so well using a simple language before introducing the complex stuff.
In general, this guide will provide:
- Newbus and the infrastructure used to manage the hardware devices on FreeBSD
- Working with PCI, ISA, USB and various other buses
- How to control and communicate with the hardware devices from user space
- How Common Access Method (CAM) can be used to manage host bus adapters (HBAs)
- The deep concepts on how the virtual null modem terminal driver, the USB printer driver, the Intel PCI Gigabit Ethernet adapter driver, and other important drivers work.
- How to use Direct Memory Access (DMA) to improve system performance

5. The Best of FreeBSD Basics
For the past several years, networking and security instructor Dru Lavigne has constantly been putting down her learning experiences with the FreeBSD system administration and how open-source software can be used in a set of over 110 guides. Many readers around the world have recommended and really praised her work.
The Best of FreeBSD Basics is one of her works that really helps system administrators walk through the basics of FreeBSD, with practical advice for performing common tasks. This is the greatest way to learn FreeBSD and Unix in general. Other Darwin, DragonFly, Linux, Mac OS X, NetBSD, and OpenBSD users will also get some vital information from this guide.
The guide covers a wide range of FreeBSD and open-source topics. The basics include step-by-step instructions, things to watch out for etc. You get to learn how to install an X11 server and set up desktop environment, compare the common tasks with Linux, user administration, how to play video and audio files, managing backups, networking, configuring firewalls, how to improve security, how to filter spam etc.
