Description

As Linux continues to gain prominence, there has been a rise in network services being deployed on Linux for cost and flexibility reasons. If you are a networking professional or an infrastructure engineer involved with networks, extensive knowledge of Linux networking is a must. This book will guide you in building a strong foundation of Linux networking concepts. The book begins by covering various major distributions, how to pick the right distro, and basic Linux network configurations. You'll then move on to Linux network diagnostics, setting up a Linux firewall, and using Linux as a host for network services. You'll discover a wide range of network services, why they're important, and how to configure them in an enterprise environment. Finally, as you work with the example builds in this Linux book, you'll learn to configure various services to defend against common attacks. As you advance to the final chapters, you’ll be well on your way towards building the underpinnings for an all-Linux datacenter. By the end of this book, you'll be able to not only configure common Linux network services confidently, but also use tried-and-tested methodologies for future Linux installations.

TL;DR: This book is legit! Buy it. Read it. Thank me later.I'm a developer, looking to learn more about TIP/IP networking (to better architect cloud applications, etc.). This book offered me exactly I was looking for, and then some.It's really aimed at network admins, rather than developers; It delves deeply into many topics that would apply to building/managing a network but not so much to shipping web apps (ex: VoIP networking, managing switches/routers, etc.). That said, these are many things that will benefit anyone that's even casually interested in managing their home network, much less understanding how an office network functions (or building their own IP network for whatever purpose).What I really like about this book is that in each chapter the author does a nice job of introducing each topic with a theoretical foundation and real-world context, before then delving into the specifics of technical protocols/configurations/implementations, etc. Even for things I'll never care about (like support or debugging VoIP), he grounds each topic in ways that keep it (mostly) interesting and digestible.A final point that I really appreciated is that the author shares extensive valuable insights related to network security topics and considerations, both from an attacker's perspective (white hat penetration testing, etc.), and the opposing defensive perspective (admins, etc.). This is the entire focus of the last 3 chapters, but it's also present to varying degrees throughout the book.Whether you're managing a network, building apps, working in DevOps, or just trying to secure your home wifi, this book is a solid winner!** My ONLY critique would be that throughout the book the Linux examples use Ubuntu 20.04 almost exclusively. Ubuntu is a free and popular distro which anyone can easily acquire and use with VirtualBox to follow along throughout the book – but for anyone using RedHat/etc. you'll need to do more work to apply some of the examples to your own environment(s).

Donald A. Tevault Apr 02, 2022

This is a very well-written book, which is ideal for anyone who's just started out learning Linux networking. It starts out with a great overview of basic networking theory, and then goes through the basic networking commands. Then, you get an overview of the various networking services that Linux can run, and how to set them up. Everything is clearly explained, so even if you're a Linux beginner, you won't have any problems following the material.There is one thing though, of which the Linux beginner needs to be aware. That is, in Chapter 2, the author gives the impression that he's performing the demos on Ubuntu Server, when in reality he's performing them on Ubuntu Desktop. The difference is that Ubuntu Server and Ubuntu Desktop use two different types of networking services, which means that these demos won't work if you're using Ubuntu Server. But, if you use Ubuntu Desktop, everything in Chapter 2 will work just fine, and everything after Chapter 2 will work fine on either Server or Desktop. (I'm not taking off a star for this. It's just something that the reader needs to know about.)Overall, a great book, which I highly recommend.

Very enthusiastic and passionate writing and information!

Kenneth L. Armstrong Mar 08, 2022

This book’s writing style is clear and easy to understand. There is a clear focus on not just installing and configuring various network services but also an extensive amount of coverage is included detailing the procedures needed to secure and test these services for vulnerabilities (particularly with DNS, DHCP, and SNMP among others). A plethora of tools and techniques for monitoring and analyzing network traffic from a variety of sources is covered really well.There is ample coverage of the use of legacy networking tools and their modern equivalents. An example of this includes the usage and comparisons between the old ifconfig command set and the new ip command set. Another example is the legacy iptables commands and the newer nftables commands to manage firewalls. However, there are no examples that use firewalld, but the usage of nftables makes up for this omission.A fair bit of network theory is sprinkled throughout the book and the basics (as well as some more advanced aspects of networking) are covered well in Chapter 3 along with useful examples that utilize numerous tools that can be used to explore these topics. I especially appreciated the sections that demonstrated the use of the /proc kernel file system area to explore various network connection properties.Chapter 5 contains some very excellent examples on how to create an inventory of your network environment to be used with security audits. Although SELinux and AppArmor were both discussed, their coverage was extremely light without much in the way of useful examples. The rest of the security topics within the book definitely ease the pressure from this mild shortcoming.The book as a whole is definitely written for the network and server administrators in a secure corporate environment. There is plenty in here for a home network setup, but there are plenty of other books on those topics. The key audience here are those working in very large and global networks with regards to load balancing and dealing with various cloud services and centralized authentication systems. I recommend this book to any Linux professional, as there is just too much good information contained within these pages that systems and network professionals need to know.
