    Cannot turn off DHCP in RedHat 9

I'm running a RedHat 9 system, and I'm trying to configure its primary
network interface (eth0) to have a static IP address.  I run 'setup',
configure all of the proper settings under 'Network Configuration' (to
my knowledge), and verify the contents of
/etc/sysconfig/network-scripts/ifcfg-eth0:

DEVICE=eth0
ONBOOT=yes
BOOTPROTO=static
IPADDR=192.168.8.15
NETMASK=255.255.255.0
GATEWAY=192.168.8.1

But if I do a network restart (or even a reboot, for that matter),
whenever the eth0 interface comes back up, it keeps querying my DHCP
server for its settings, and configuring the interface as such.

Am I missing a configuration step?  I've tried various things like
getting rid of the dhclient-eth0.leases file and dropping the lease
before resetting the network, but I can't find any combination that
will solve my problem.  It seems like I must be missing some simple and
obvious way to turn the DHCP client off.  But if it's down the
/etc/rc.d/init.d/network rabbit hole, I haven't found it yet.

Any help would be much appreciated.  I'm looking forward to moving on
past this one. 

Thanks,
Kevin

Here is mine from a RHL 9 system:

DEVICE=eth0
BOOTPROTO=none
BROADCAST=192.168.1.255
IPADDR=192.168.1.2
NETMASK=255.255.255.0
NETWORK=192.168.1.0
ONBOOT=yes
HWADDR=00:75:27:21:12:75
USERCTL=no
PEERDNS=no
GATEWAY=192.168.1.1
TYPE=Ethernet

This all looks fine.

One possible problem is that the script exists in three places down said
rabbit hole:

$ pwd
/etc/sysconfig
$ find . -name ifcfg-eth0 -print | xargs ls -l
-rw-r--r--    3 root     root          145 Dec 22  2004
./network-scripts/ifcfg-eth0
-rw-r--r--    3 root     root          145 Dec 22  2004
./networking/devices/ifcfg-eth0
-rw-r--r--    3 root     root          145 Dec 22  2004
./networking/profiles/default/ifcfg-eth0

If the links are broken on your machine, you could have edited the wrong
script.

Eureka!  network-scripts/ifcfg-eth0 and
networking/profiles/default/ifcfg-eth0 were both right, but
networking/devices/ifcfg-eth0 was still pointing to DHCP.  I changed it
to be the same as the other two, reset the network, and my changes took
effect.

Thanks for your help!

It's not clear from this statement whether or not all three are now
links to the same file.  If you use RedHat's GUI tools at all, you
should make sure they are, lest something get messed up again.  Even if
you don't use the GUI tools, it's easier than having to remember to
change multiple files.
