Two ethernet cards, one IP?!?
Hi all,
I have an Intel Nightshade server motherboard installed in an Intel server
case, running Debian 2.2r3 (potato).
Its on-board Intel EtherExpress Pro 100 ethernet card works fine on its
own.
When I install an Intel EtherExpress Pro 100 PCI card and configure two
ethernet interfaces, the PCI card answers to both IP addresses!
ifconfig returns separate hardware addresses for the two interfaces, yet
when I disconnect the cable to the on-board card, both interfaces continue
to function through the PCI card!
prompt:~# ifconfig

I'm running kernel version 2.2.19 with the eepro100 driver compiled into
the kernel, not as a module, but this does not seem to be the cause of the
problem; other machines running with this code compiled into the kernel
have no problem with two EEpro100's.
This is certainly freaky...
