YMMV, but I am using the PCI-X Quad GigE card from Intel, on HP DL360
and Linux Enterprise Server. All 4 card interfaces are set to
promisc. and I am using the on-board NIC as the management interface.
Not really seeing any issues described by others, though I am not
coming even close to 100Mbps, more like 10 on each interface.

I have done this. I'd advise against that particular configuration, as
I've experienced bus contention, memory leaking, and general suckage
requiring weekly prophylactic reboots, when trying to run even 2 of
the four interfaces on a quad both in promiscuous mode.
Scaling down to one i/f on the quad and deploying a separate card for
the second tap didn't fully solve, but greatly ameliorated, the
difficulties I experienced.
At this point, I'd recommend having a separate NIC in a separate slot
for each tap you want to monitor, plus a separate interface for
managing the box.

Subject: [Snort-users] Advice on quad ethernet card
Hi,
At my work they are thinking of replacing 3 snort machines by one with a
quad Ethernet card, witch will sniff 3 different lan's.
The network is only 100Mbit, will there not a lot of dropped packages this
way, and they must all send there data with barnyard to a remote mysql
server.
Is it also possible to see in the Database from witch sensor the data is
from?
TIA
Patrick
