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.
I actually wiped the drive and did a clean install of Stable, only to
find the same results afterward. I also upgraded from the 2.2 kernel to
2.4.18-1-686; it made no difference.
I've been googling all day trying to find an answer, and haven't hit the
right answer yet. If this isn't solved by tomorrow, the decision makers
are going to go with Redhat (because we're in a time crunch). Does
anyone have any insight as to what I need to do to get both NICs working
properly?
Kent,
What is the output of the 'route' command when you have the interfaces
up with and without knoppix?
