[Rack] request for information and/or instruction for Linux SysAdm class : DNS

    The problem I've had in trying to learn DNS 
is the gap between concepts and practice. I've 
hoped for a general rundown of DNS, but discovered 
that there are different approaches with their 
own solutions: authoritive, local (as on a 10. 
LAN with lots of hosts and subnets), and others. 

    Assume the two cases. 
    Start with a DNS server for a LAN. What files 
do we have to make? How to test that it works. 
All we need is a DNS server host and two or three 
other hosts on the same LAN, yes? 
    Given success for that, now let's create a 
DNS system that works for the internet. I can 
provide alternate internet-accessible hosts so we 
have three DNS servers that work together--the 
only hold-up is to learn what files we create on 
which machines and then test that things work 
without blowing somebody's expectations to 
smithereens. 

    I'd love it if you can present the talk, 
but I believe I have enough under my belt so I 
could present after you teach me in whatever 
time you have available (and I have lots of 
available time thanks to my unemployed status).
