Hi,
A friend tells me 3Com cards have some problems - like dropping all malformed packets. I have bought a 3Com 3C900 XL because it is a PCI card and it has an AUI port. Anyone ever have any problems with this or cards like 3C509 and snort?Your friend is mostly correct. The majority of current NIC cards have low-level logic built into the integrated circuits to "inspect" incoming packets, and if that packet is corrupted, it will be dropped. In most NIC cards, those dropped packets are not counted by any sort of management logic, and promiscous mode has absolutely nothing to do with whether you can "see" those damaged ethernet packets or not.
Ok, that was the main point or question I am not so sure of - whether any of this affected promiscuous mode ability of the card. Thanks for the help!
