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.

Questions

As we conclude, here is a list of questions for you to test your knowledge regarding this chapter's material. You will find the answers in the Assessments section of the Appendix:

  1. When you assess your local ports using netstat, ss, or another command, will you ever see a UDP session in the ESTABLISHED state?
  2. Why is it important to be able to determine which processes listen on which ports?
  3. Why is it important to determine which remote ports you connect to from any particular application?
  4. Why would you scan for expired or soon-to-expire certificates on ports other than tcp/443?
  5. Why would netcat need sudo rights in order to start a listener on port 80?
  6. In the 2.4 GHz band, which three channels make the best selection to reduce interference?
  7. When would you use a Wi-Fi channel width other than 20 GHz?
