[LARTC] Ethernet equipment testing with two NICs

[Matthew R. Dempsky]

I have a Linux 2.6.16 machine with two gigabit ethernet adapters that I 
would like to use for testing Ethernet equipment---right now just an 
Ethernet cable, but later switches, bridges, etc.

I tried assigning the two adapters IPs of 192.168.50.1 and 192.168.51.1 
and then setup the routing table to direct 192.168.51.0/24 traffic to 
the first adapter, and 192.168.50.0/24 traffic to the second, but when I 
run ``ping -I 192.168.50.1 192.168.51.1'' the packets are routed over lo 
instead of eth0/eth1.

Can someone suggest an alternative setup that will work?

Thanks.
