We wrestled for several days, and never did find a solution. We even installed on a completely different box with differing NICs, on different network jacks (in the meanwhile, the original 2-NIC Debian box was reduced to one NIC, and a second Redhat box with one NIC, were put into production to solve our immediate need, planning to replace both with the one 2-NICed Deb box when we get both NICs working). We finally, on a grasping-at-straws type of effort, upgraded to the 2.6 kernel, and lo and behold, now we can ping both interfaces. Making progress. I don't have enough networking experience to explain the differences; just wanted to report that what we're trying to do we could not get done with a 2.4 kernel, but we can with a 2.6. -- Kent -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

Two nics; only one works at a time
I've got a freshly installed Debian Stable box with two NICs, a 3c509 and a 3c509c. In /etc/network/interfaces, I have them defined thusly: auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp auto eth1 iface eth1 dhcp When I (re)start networking, ifconfig shows both cards to be configured with all the proper numbers, but networking out is "iffy" (I haven't been able to pin down a pattern), and I can ping from a different subnet the eth1 card but never the eth0 card. If I comment out one of the cards (it doesn't matter which one) in "interfaces" and restart networking, I can then ping from the different subnet the card not commented out. In other words, both cards work, but only one at a time. I've also tried static IP addresses with essentially the same results. I've booted off a Knoppix 3.3 CD, and both cards worked as expected, and I was able to ping both cards from a different subnet.
