Well...  I'm making a semi-educated guess:  You're on a switch or a
'auto-sensing' hub.  If that's the case you're only going to see the
traffic destined for that box (switch) or for that 'speed' of card
(auto-sensing hub).

If it's a Cisco switch, look into configuring a SPAN port.  If it's
another brand, it might be known as 'port mirroring'.

If it's a auto-sensing hub, you're only going to see traffic for that
speed (10 or 100 mb) of card.  You'd have to move to a true 'dumb hub' to
have it work.

Hope that helps!
