/etc/sysconfig/network should do it.  It's sourced by /etc/rc.d/rc.sysinit

Okay, this is really weird, hostname returns ftp.cnhp.colostate.edu.  I
have it set to mail.cnhp.colostate.edu in /etc/sysconfig/network, and if
I do a nslookup, it's listed as mail with ftp as an alias.  What's up
with this?

Adam,
When I built the new boxes in the dept I did it by cloning. These are the
files I changed to give the a new machine its identity:

/etc/HOSTNAME    put in the hostname
/sysconfig/network   put in the  hostname

Just those two changes and I've had no problems.

Make sure that your reverse DNS and DNS are correct...  What DNS thinks
your computer is named, and what your computer thinks is is named
should probably jive -- at least a little...

Err.... I should say that dnslookup only looks at the DNS records, and
never actually asks the machine what it thinks its own name is.

When I set up my Redhat 6.0, I entered my IP addy as xxx.xxx.xxx.037
Note the '7' on the end. After installation was complete, my computer
thought it was .031. It even told the outside world that it was .031. I
had to go into the config files and manually change it back to a '7'.
Now my computer thinks it is .037, and it tells the world that too. But
why does Redhat mess that up? It did it when I installed 5.1 as well.

The problem is the leading 0.  I chewed out the housing department
about this once, something like two or three years ago... But they
don't listen to me.  Maybe cuz I rant too much.  :)

To be jaunty, and because I was annoyed at Housing Networks already,
I thought I'd be jaunty and type in the IP address EXACTLY as it was
typed on the little form.  I got the same effect you saw.

Anyway, the scanf thingy in C will consider any number starting with
a 0 to be in octal.  Sooo, 037 is octal comes out to... something else
in decimal.  If you wanted to be especially jaunty, you could convert
it to hex, and put 0x in front of the numbers...

Alternatly, you can also convert the whole 4x8 ip string into a 32bit
word.  Check out samspade.[org|com|???] for more stupid tricks...

The odd thing is that my IP address was .037 when I was in the halls,
too.... Coincidence?  Nah.  Prolly not.

Actually when I got my ethernet card, I had Housing install it for me.
At the time this was free, so I figured I'd let the experts do it. I had
forgotten that when he was entering the data for the card, he had to
ignore the leading zero. He tried it three times with the leading zero
before he remembered that housing connections have that quirk.

it comes out as 31! Amazing bit of magic.  :)

It's a conspiracy! 
<housing code>
if student == CS 
	then ip = .037
</end code>
