I get by pretty well on a lot of other topics, but I seem to not be able to conceptualize the whole big picture when it comes to networking. If there were a good on-line tutorial or something about what all these things are supposed to mean,
I learnt about networking by reading Douglas Comer's excellent book[1]. A print copy is nice to have but there are ebook and PDF versions available. There are many others on how TCP works around. When you understand how networking works, what goes into /etc/resolv.conf, what the output of standard tools like "route", "ip", "ifconfig" mean, then the issue of the settings in /etc/sysconfig/networking/config will be. along with the explanatory comments therein, self apparent. https://i-technet.sec.s-msft.com/dynimg/IC213263.gif Trying to explain those variable as a starting point, if you don't know what the resulting effect in, say, /etc/resolv.conf actually means will be laborious and frustrating, both for you and for the person trying to explain. And that knowledge will not be portable to other systems such as RedHat or Ubuntu or - !shock! !horror! - Microsoft Windows. What I mean by this is that each vendor has their own 'added value' approach. Yes there are efforts to standardize, but they most often meat with resistance one way or another. Certainly Suse and openSuse make it clear that they modify the upstream version of many core packages, and in some cases lag way behind other distributions. But if you know the generic principles rather than the specifics about one distribution, you can easily accommodate. Many of the people here are professionals in their day jobs and use AIX, HP/UX, Sun/Solaris or other versions of Linux and move backwards and forwards between them because they understand the principles and how to apply then rather than treating each one 'sui generis'. See this debate, for example: http://www.zdnet.com/blog/murphy/why-many-mcses-wont-learn-linux/1137 Compared to Microsoft (or even IBM's SNA) TCP is both simple and regular. But there is a lot of it. Do not confuse volume for complexity. TCP/IP is not inherently complex.
