I'm evaluating a move from span ports to taps this year, and I've been looking at these: http://www.netoptics.com/10-100-tap.html It looks like in order to do this I will need two nics to effectively monitor a network: one for incoming packets and one for outgoing. Is this correct? (if this is covered in a prior post or FAQ, please slap me down and I'll look it up)
Have a look at the IDS deployment guides: http://www.snort.org/docs/#deploy Taps usually split the ether stream into two streams. One is TX and the other is RX. You will need two nics to be able to really deal with that. If you're on a Linux 2.4+ kernel you should be able to use the bonding patches (http://bonding.sf.net), if on *BSD you should be able to use bridging, and if on Solaris--I think!--you could use trunking (Sun software) to combine the two streams into one. Hope that helps! ----- Erek Adams "When things get weird, the weird turn pro." H.S.
