dual home RH linux

Hi,

I have an RH 7.3 box that was using 1 NIC. It worked fine.

I added another NIC set the IP configuration for a different C subnet. It loads on boot as eth1 and everything looks fine. However, all traffic to the subnet that eth1 is configured for is unreachable.

No firewall
all other IP's are reachable

When I boot it up in Windows it works fine, so the nic is functioning.

Is there anything else I can try.

im not sure, being a newbie myself, but i think you have to edit your config and give your first nic, ie eth1 an ip address, and your second nic, ie eth02 and seperate address. I will look arouind but i think its under Network Config (NEAT).

both nics eth0 eth1 have seperate IP configs on seperate subnets. So in theory the can work independently.

What's your routing table look like?

Code:

id10t@id10t:~$ /sbin/route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
216.155.96.9    0.0.0.0         255.255.255.255 UH    0      0        0 ppp0
192.168.0.0     0.0.0.0         255.255.255.0   U     0      0        0 eth0
192.168.1.0     0.0.0.0         255.255.255.0   U     0      0        0 eth1
127.0.0.0       0.0.0.0         255.0.0.0       U     0      0        0 lo

id10t@id10t:~$

is what you are looking for. Otherwise use route to add a new route to that particular subnet.

Can you ping from one nic to the other? That may give you some indication as to where to start looking. Also, you may have to add the other nic to your lmhosts file, if it does not have the same name and is on a different subnet.
