hi,
i have a fedora core 3 machine, but have the following network problem:
one of the ethernet ports (eth1) appears to be up and running but the
machine has no connectivity if just eth1 is connected:
here is the route:
Destination Gateway Genmask Flags Metric Ref Use Iface
205.150.209.0 * 255.255.255.0 U 0 0 0 eth0
205.150.209.0 * 255.255.255.0 U 0 0 0 eth1
default mci209.3z.ca 0.0.0.0 UG 0 0 0 eth0

(I've deleted one routing entry that isn't relevant to this discussion.)

The "default" entry determines what happens to traffic sent anywhere but 205.150.209.0 - it is sent to mci209.3z.ca, which is supposed to be directly accessible via eth0. When eth0 is shut down, the default entry goes away.

eth1 will never be used for outgoing traffic unless eth0 is shut down. Reverse DNS suggests you are trying to run web servers at both IP addresses, so this may not be a good thing.

Note that I said "shut down", not "disconnected". Nothing changes if you pull the plug on eth0.

Why don't you tell us what you are trying to do. Looking at archives of this newsgroup or some networking FAQ's would be good idea also.
