Dynamic hostname

[William Lacy <billy@swt.edu>]

I want to have my hostname assigned by the DNS server.  This should be 
set up for me but I'm not sure how it works on my end as far as my 
computer knowing how to name itself, etc.  In the past I have changed 
the hostname of a computer by editing a startup script but I can't seem 
to find it this time around.

Basically, I am getting a domain name assigned by the DHCP server that 
reserves my MAC address- will Debian automagically figure this out and 
call itself that name? Also, right now the computer names itself 
something else- do I need to change this and where do I do it?

Any help will be greatly appreciated!
