I fail to see what your problem has to do with "security". You will
probably get more responses on the standard list.
We were doing experiments in routing with two suse 10.2 machines
interconnected directly with gigabits cards, acting as routers for three
other PCs. These two, lets say A and B, did not see each other correctly.
A could ping B, but B could not ping A. Looking with wireshark, I saw that
B was sending ARP requests on the interface to determine the MAC address
of it's partner and getting no response.
We switched to another card, and it worked. We removed the original card
(brand new gigabit, I think from Realtek), cleaned the contacts with a
rubber eraser, reseated, and it worked fine.
The point why I mention this is because the card failed to get a MAC
address from the other side. I think it was some kind of hardware failure.
