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.

Technical requirements

In this chapter, we'll be exploring load balancer functions. As we work through the examples later in this book, you can follow along and implement our example configurations in your current Ubuntu host or virtual machine. However, to see our load balancing example in action, you'll need a number of things:

  • At least two target hosts to balance a load across
  • Another network adapter in the current Linux host
  • Another subnet to host the target hosts and this new network adapter

This configuration has a matching diagram, Figure 10.2, which will be shown later in this chapter that illustrates how all this will bolt together when we're done.

This adds a whole level of complexity to the configuration of our lab environment. When we get to the lab section, we'll offer some alternatives (downloading a pre-built virtual machine is one of them), but you may just choose to read along. If that's the case, I think you&apos...
