Which version of tcpdump? What network card? What is the network
configuration (what is on the wires)? Could it be that your network card
is not in or does not support promiscuous mode? Look at the output of
'/sbin/ifconfig eth0' and look at the third line:
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
(not running tcpdump) verses
UP BROADCAST RUNNING PROMISC MULTICAST MTU:1500 Metric:1
(running tcpdump on a card that supports promiscuous mode). This could
also be an IPv4 verses IPv6 issue depending on what is on those wires.
