Setting hostname with DHCP
Dear list,
I have scoured the web and even read the generally helpful
Chapter 10 - Network Configuration from Debian Reference
http://www.debian.org/doc/manuals/reference/ch-gateway.en.html,
but I cannot figure out how to set hostname and domain using
dhcp.
On my box, "Linux debian 2.4.18-bf2.4 #1 Son Apr 14 09:53:28
CEST 2002 i586 unknown," DHCP works fine in that it gets an
ip address and even an associated name for the computer, but
"hostname" returns "debian", "hostname -d" returns nothing,
and "hostname --fqdn" returns "debian".
The computer is most frequently plugged into a campus
network for long periods, and my preferred behavior for it
would be that it gets the hostname and domain via DHCP and
sets them. I cannot get a static ip address from the
administrator. I am stuck with DHCP, but it would be
helpful if the host and domain names were set from DHCP on
bootup. I usually but *not always* get the same IP address
and name, so I don't want to rely on setting /etc/hostname
permanently.
Isn't there an option for /etc/dhclient.conf that will set
the system hostname and domain name after running dhcp?
BTW, here is the first line of my dhclient: # $Id:
dhclient.sh,v 1.1.1.1.2.1 2002/02/11 03:44:26 eparis Exp $
In my web browsing, I have seen some hacks, e.g., after
starting the network in rcS.d, extract the hostname with
ifconfig or even nslookup and then insert that text into
/etc/hostname (which at the moment contains "debian").
This seems inelegant, but let me know if it's the only way.
Best regards,
Michael
