Overview of this book

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.

Summary

With our discussion on DNS drawing to a close, you should now have the tools available to build a basic internal DNS server and a standard DNS server facing the internet. You should also have the basic tools to start securing these services by editing the various configuration files for the Linux bind or named service.

In addition, you should have some familiarity with troubleshooting various DNS services, using tools such as dig, kdig, curl, and nmap.

In our next chapter, we'll continue on with a discussion on DHCP, which—as we've seen in this chapter—is definitely separate, but still can be related to DNS.
