In this chapter, we worked through setting up our environment. We discussed virtual machines and physical machines as network nodes, and we even set up a Debian and CentOS installation or two.

Now that we've set up our environment, it's time to dive in and get started. In Chapter 2, Revisiting Linux Networking Basics, we'll cover all the commands we'll need for our journey, for example, configuring network interfaces, manually connecting to networks, and setting up Network Manager. Stay tuned!
