Hi Chris,
"UP BROADCAST RUNNING PROMISC MULTICAST MTU:1500 Metric:1"
Your ifconfig output does show the interfaces to be running in promiscous mode.
The best method forward from here would be to sniff the packets on the interfaces using tools like ethereal and analyse them.

Hi Alex,
In the case you mentioned previously, does ifconfig show the interface in promisc mode? I have tried further investigating whether or not the interface is in promisc mode by using ethtool, a soft tool, however unsuccessful. I also attempted to use a hub on eth0 to see if tcpdump would pick up the packets in promisc mode; the packets are successfully captured on the hub. [I did not test eth1, but I shall tomorrow morning.] Both network interfaces are the same model/brand. Listed below is a snapshot of my ifconfig and a snippet from my lspci.
This list is pretty responsive - I just wanted to say thanks to everyone for taking time to help me out. ;)
Mahalo,
Chris
