Hi Chris,
Thanks for responding so quickly.
Yes, I've heard from my sysadmin that when my machine sends out an
initial DHCP address request, the (DNS server?) network identifies my
machine's mac address and associates it with my machine's
"hostname". What I don't understand is how to tell our DNS server
what I'd like the machine to be called. I get the impression from
our sysadmin the this naming is automatic and depends on information
that I somehow send to the DNS server.
In the same vein, if I have no control over my machine's hostname,
why does one step of the YDL install process involve "setting the
hostname"? Is this step a placebo to make me feel like I have more
control?
Thanks so much for your reply!

Hi Nathan,
There seems to be a bit of a misunderstanding as to how hostnames
work and propagate. You cannot do what you are trying to do by
configuring your machine. If you want this to work, you need to
contact the local LAN admin responsible for DNS. Setting it in your
/etc/hosts file or changing your hostname will only be seen by that
machine. No other machine has access to either of those, so these
changes will not propagate on the net. This is the precise purpose for
DNS.
Hope this helps.
Cheers,
Chris
