Ron, All fixed now, the cards both work fine ;-) Ben
RE: [luau] Routing table problems...
Sorry I didnt catch the beginning of this thread, hope the following hasnt been recommended... When ever I build a multihome box I learned from the ISA card days to run the diagnostic software to confirm whether the card even works for starters, and run the diagnostics test on each card. The io and irqs for info sake, would round out my test. Just to get started.

Re: [luau] Routing table problems...
Devon, I finally axed the /etc/sysconfig/network-scripts eth1.route and ifcfg-eth1 files. So far that seems to have fixed the problem. VR, Ben

Re: [luau] Routing table problems...
Devon, Tried all that stuff. Same symptoms when I restart the network. I even disabled eth1 but that didn't fix it either. I believe the system is reading a file somewhere when the network starts. I'll dig and see if I can find it. Thanks, Ben
Re: [luau] Routing table problems...
Ben, In truth, your problem has nothing to do with routing tables at all. It is the fact that you have two network interfaces configured with IP addresses on the same subnet. If you were to merely disable the second NIC on startup, all of your troubles would go away. If this is not an option, you need to specify which network interface is your gateway device so that your system does not try to send packets out on your unused interface. The way to accomplish this is to specify your default route in this manner: route add -net 192.56.76.0 netmask 255.255.255.0 dev eth0 intentionally specifying the interface on which to route the traffic. This is typically done in the /etc/sysconfig/network file by adding a line: GATEWAYDEV=eth0 Let me know if this was helpful.

Re: [luau] Routing table problems...
To my knowledge, RH stores its routing tables in /etc/sysconfig/route, or at least some file in /etc/sysconfig. I'm not quite sure on the syntax though. Anyway, playing around in sysconfig may shed some light on the subject. I'm sure redhat also has a tool to tweak them with a fancy frontend. Another thing you may look at is the networking init script (in /etc/init.d) itself. Most of redhat's scripts provide some way to save the current configuration as the default. Running the init script with no options, using --help, or viewing the file (99.9% chance it's just a "very small shell script"(tm) ) may give ideas. --MonMotha
[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. [EMAIL PROTECTED] init.d]# /sbin/route -e Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface localhost * 255.255.255.255 UH0 0 0 lo 192.168.1.0 * 255.255.255.0 U 0 0 0 eth0 default router 0.0.0.0 UG0 0 0 eth0 [EMAIL PROTECTED] init.d]# This is what the routing table looks like when the network restarts [EMAIL PROTECTED] 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 UG0 0 0 eth1 [EMAIL PROTECTED] 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.
