AW: [Snort-users] 3 or 4 NICs in a sensor?

I'm running a 6 NIC RH 7.2 box with 5 snort instances listening on 5 NICs
(3x 100Mb/s, 2x 10Mb/s, not highly saturated). Works like a charm (ok,
traffic has been rising over the month and snort reports some packet drops
on 2 interfaces with values about 0.0xx%). Tuning should help to get back to

You might take a look on my HOWTO at where I
described such a configuration.
