Description Chris Kloiber 2003-01-27 20:18:09 UTC
Description of problem:

A customer's large Oracle server (10 nics, 2 onboard and 2- 4 port cards) 
He can use both eth0 and eth1 (the onboard cards) on the same network
( but add any of the others and this problem occurs.

I verified I see the same problem using single 4 port card on my 7.2 Alpha at
home. When more than 2 nics are configured in the same subnet, all of the cards
in that subnet stop working and the route -n looks like:

Destination     Gateway         Genmask         Flags Metric Ref    Use Iface   U     0      0        0 eth2   U     0      0        0 eth2   U     0      0        0 eth0   U     0      0        0 eth1       U     0      0        0 lo         UG    0      0        0 eth1

I currently don't have the hardware to test this in 8.x

Well, for one, the GATEWAY in the network file is wrong. It should read:


although i doubt that this is the source of the problem.

Unfortunately i don't have the hardware here either to reproduce the problem, so
until i have this bug will have to wait.

Read ya, Phil
