I've given a couple of pointers to RFCs. At this point, you may want to
go to <URL:
http://www.rfc-editor.org/> For those who don't know, RFCs
are documents which typically describe the behaviour of some protocol or
expectation on the open public Internet. An RFC might also be listed in
another index, such as STD, for the Standards. RFCs have a "Status:"
which defines how they are regarded by the Internet Engineering Task
Force (IETF). Learn to read RFCs, and how to search them. They will
become your dear friends, unless you are careless enough to venture
outdoors once every so often. ;^) Also, locate your nearest
(network-wise) public RFC mirror. They are _very_ widely mirrored.
Unfortunately, "source routing" isn't in the title of the relevant RFC,
otherwise you could simply use the excellent search facility on
www.rfc-editor.org. At this point, there are a few pointers which any
mail administrator should know:
rfc-index.txt
Especially learn to notice the "Obsoleted by" and Updated/Revised by
labels, and track those down.
rfc2821.txt
Simple Mail Transfer Protocol
Your life will be so much easier once you've read this, at least
once.
rfc2822.txt
Internet Message Format
Pretty much what it says. Used in emails and USENET, amongst other
places.
std3.txt : RFC 1122 + RFC 1123
Requirements for Internet Hosts
The last one is dated; some of the more "liberal" behaviour should be
avoided -- it is sadly no longer appropriate to be as trusting as it
once was. But it will give you the rough pointers, to where else you
need to be looking.
Then you can start browsing some of the others.
If you _really_ want to learn more about the Internet, its protocols,
and how they fit together, your best bet is to shell out some money for
the three-volume set by the late W.R.Stevens, "TCP/IP Illustrated".
I was going to start providing pointers to tools for sysadmin, but
decided instead to point to a couple of useful sites:
<URL:http://www.usenix.org/sage/>
-- System Administrator's Guild; public website includes book
pointers, web pointers and more
<URL:http://www.stokely.com/>
-- led to Celeste Stokely receiving the SAGE Outstanding Achievement
Award in 2001.
<URL:http://www.google.com/>
-- Worship Google.
