I have installed 3 nic, but only one can "ping" other machine, why?

My server (it has 2-CPU) has two Intel Gigabit netcard, and I added a DFE-530TX netcard, the OS is Redhat AS 2.1, their IP are 192.168.3.100, 192.168.3.101, 192.168.3.102 respectively. Only when the 192.168.3.102 was link to network, I can ping 192.168.3.138( other machine ), other two nic can not do so.
I have edited /etc/modules.conf and /etc/sysconfig/networ-scripts/ifcfg-ethN, but the problem can not be resolved.

When I typed route command, it displays following:

Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.3.0 * 255.255.255.0 U 0 0 0 eth2
192.168.3.0 * 255.255.255.0 U 0 0 0 eth1
192.168.3.0 * 255.255.255.0 U 0 0 0 eth2
127.0.0.0 * 255.0.0.0 U 0 0 0 lo
default my.router 0.0.0.0 UG 0 0 0 eth0

Anybody can help me?

check this thread

nice loop, eh?

What does 'ifconfig' have to say?

Please do not post the same thread in more than one forum. Picking the most relevant forum and posting it once there makes it easier for other members to help you and keeps the discussion all in one place.

* cough cough * You did start the other networks right???

I did that once. It sure helps when you start them. They communicate much better.

ifconfig, as mentined above, will tell you if you have or not.
