I'm trying to set up 2 NICs so that my linux box can be connected to
two separate networks.
The two cards are both 3coms eth0 is a 3c905b (PCI) and eth1 is a
3c509 (ISA). eth0 is 192.168.1.1, eth1 is 192.168.1.2
Both cards are recognized on start up. With both cards connected to
the same network I can ping both addresses no problem but if I try
to put one card on one network and one on the other - no go.
I looked at /var/log/messages and I when eth1 is intialized there
is the message Set Rx mode to 1 addresses. A few lines later the
message Set Rx mode to 0 addresses appears. From ifconfig it does
look as if eth0 is doing all the most of the receiving and eth1 is
doing most of the transmitting.
Am I missing something on the software side or is this a hardware
problem? Should I try a different brand of NIC?
