Re: eth1 and eth2 Breaks Default Route

There was a typo in the original message. The correction follows: A buddy of mine asked the following question on comp.os.linux.networking, but those folks don't fully understand why an interface would want to be set to 0.0.0.0/0. If anyone can shed some light on a fix, I'd like to know. Here's the original question: I have Red Hat 9 on an X86 with three (3) interfaces working as an IDS. eth0 is my management interface with a live IP address. eth1 and eth2 both have their IP addresses set to 0.0.0.0/0 for data collection. All IP addresses are set in /etc/sysconfig/network-scripts/ifcfg-eth?. When the box boots up my default route is shot through eth2 (should be eth0) even though I have my GATEWAY keyword set to the gateway I want. The following are my ifcfg-eth? entries: /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE=eth0 onfiltered=yes BOOTPROTO=static IPADDR=1.2.3.4 NETMASK=255.255.255.0 GATEWAY=1.2.3.1 /etc/sysconfig/network-scripts/ifcfg-eth1 DEVICE=eth1 BOOTPROTO=static BROADCAST=255.255.255.255 IPADDR=0.0.0.0 NETMASK=0.0.0.0 NETWORK=0.0.0.0 onfiltered=yes GATEWAY=1.2.3.1 /etc/sysconfig/network-scripts/ifcfg-eth2 DEVICE=eth2 BOOTPROTO=static BROADCAST=255.255.255.255 IPADDR=0.0.0.0 NETMASK=0.0.0.0 NETWORK=0.0.0.0 onfiltered=yes GATEWAY=1.2.3.1 I added "GATEWAY=1.2.3.1" to ifcfg-eth1 and ifcfg-eth2 to see if that would fix things. It doesn't... Q1: How do I get the system to recognize the proper gateway as specified in ifcfg-eth0? Q2: Is there a way to tell an interface to boot in promiscous mode? I'm thinking there is a keyword that can be placed in ifcfg-eth?, but I can't find any reference to that... __________________________________ Do you Yahoo!? The New Yahoo! Search - Faster. Easier.
