[luau] Routing table problems...

Aloha and Hauoli Makahiki Hou,
Today a strange thing happened. My routing tables got messed up and
now although I can fix them, they don't stay fixed when the network
restarts. I can't seem to find any reference to files that hold the
'non-volatile' parts of networking info to track down the problem. So
any help would be greatly appreciated.
My box is RH 9 behind a router/firewall. This box uses a fixed IP
address of 192.168.1.21 and .22 (two nics). Right now only eth0 is
connected. The router is IP address 192.168.1.1 on the LAN side.
Everything is OK with the router and all the rest of the boxen. Just
this one box is giving me trouble.
This is what I want it to look like when I am done configuring the box.
[root at valinux init.d]# /sbin/route -e
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt
Iface
localhost * 255.255.255.255 UH 0 0 0
lo
192.168.1.0 * 255.255.255.0 U 0 0 0
eth0
default router 0.0.0.0 UG 0 0 0
eth0
[root at valinux init.d]#
This is what the routing table looks like when the network restarts
[root at valinux init.d]# /sbin/route -e
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt
Iface
192.168.1.0 * 255.255.255.0 U 0 0 0
eth1
192.168.1.0 * 255.255.255.0 U 0 0 0
eth1
169.254.0.0 * 255.255.0.0 U 0 0 0
eth1
127.0.0.0 * 255.0.0.0 U 0 0 0
lo
default router 0.0.0.0 UG 0 0 0
eth1
[root at valinux init.d]#
As you can see most of the entries are eth1, not eth0, and there are a
few other mistakes in the table that keep the networking stuff from
functioning correctly.
After I rebuild the routing tables by hand, all is OK until the network
gets restarted. Why is this, and what can I do to correct it?
Mahalos in advance,
Ben
