Struggling with DHCP

I am running Mandrake 9.1 hooked up to a Netgear RT314 router. The
router assigns the IP address.

Apparently the router is also assigning the hostname for my linux box
which is getting set to dhcppc2 at the moment. When I call
hostname from a shell, I see dhcppc2 returned. When I browse to the
linux box from my W2KP box (linux box is running samba), I can see
that the name is dhcppc2. Of course, if I clear the DHCP tables in
the router, the computer name will change depending on who requests an
IP first. My windows box maintains its name that I set for it. So, I
figure this has to be a linux configuration issue. So,

I added a line to dhclient-eth0.conf:
send host-name "AMDGhz20".

I also added a line to /etc/sysconfig/network:
DHCP_HOSTNAME=AMDGhz20

Rebooted after each change...so far no luck.

I set /etc/HOSTNAME to:
AMDGhz20

again after reboot no luck...changes seem to be ignored to.

Then I noticed in /etc/sysconfig/network-scripts/ifcfg-eth0 a variable
NEEDHOSTNAME=yes. So I changed that to:
NEEDHOSTNAME=no

And of course, after a reboot, no luck. machine name still dhcppc2

So, what do I change to make sure my linux box has a "static" name
that I assign instead of getting something from the router?

I appreciate anyone who is able or willing to help....

You can find hostname configuration files with this command
find /etc -type f -name "*" -print | xargs grep -I $(hostname)

For Redhat/Makdrake here are snippets from some of my Mandrake files
which set hostname, ip address, or used in resolving/setting
hostnames/ip addresses.



cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=fw.invalid <==============
GATEWAY=12.209.206.1
GATEWAYDEV=eth0

cat /etc/hosts
127.0.0.1 localhost.localdomain localhost
192.168.1.10 fw.invalid fw <==============

If dhclient is running, remove the "host-name" from the line that says
"request ... host-name" in /etc/dhclient.conf.

If you're using pump, I think you may be out of luck. On second thought,
you might try using pump instead of dhclient, as pump doesn't seem to be
able to configure the hostname (or at least, you can't tell it not to).

It seems that adding the HOSTNAME line to my /etc/sysconfig/network
file set the hostname correctly.

Thanks for the help
