Linux Networking Fundamentals needs work

[gregbo]

In the intro.md prerequisites, it's stated that readers need to have knowledge of jargon in the TCP/IP stack such as DNS, HTTP, etc. It's not clear if these protocols are the jargon being referred to, or jargon associated with these protocols. Anyway, I would suggest that rather than worrying about jargon, readers should have a grounding in the basic principles of these protocols. I recommend providing a link to Peterson and Davie's Computer Networks: A Systems Approach, an open-source textbook covering the fundamentals of computer networking from a multi-layered, system of components perspective. I believe after reading (at least) the first three chapters, your readers will have enough of a grasp of computer networking fundamentals that they will better understand how to perform SRE networking tasks on Linux (and other) systems.

Peterson and Davie's is a good suggestion
Let me see how we can rephrase the intro.md

If the students will be using RHEL, I would also suggest that they install several of the networking tools packages such as iproute, iputils, and nmap, if they haven't yet been installed. These packages contain programs such as ip, ping, and ncat, which can be used in conjunction with learning the networking fundamentals.
