?
I have 3 networks separated by T1 links, and one server that I like to track. On a 
switched network, I use old fashioned 3Com Super stack Hubs. I got Network switch->Hub 
(NTOP/NPROBE box and Server). On the wan links/Gateways I go from Router/Telco 
equipment to Hub (NTOP/NPROBE) to switched network. I even have IP Addresses assigned 
to the NTOP box. I tried port mirroring, but had some problems, and was too lazy to 
figure out if it was OS (RH9) related, switch (Dell GB switch) or NTOP related.

Add a NIC to the ntop box, don't give it an IP address and use a Hub (TRUE
hub, not a switching hub) or a port tap to gain access to the traffic flow.

This has been discussed on-list (although I don't remember the thread well
enough to point it out - search for 'unnumbered interface', maybe) and
there's some stuff in docs/FAQ.
