To check if it was simply the hosts I was testing against, I downloaded and ran tcpdump (which also uses libpcap). The situation is this: If I run tcpdump with no filter (ie. no parameters) I get the normal display. If I specify any filter of any kind, the filter works properly, but absolutely NO incoming packets are display WHATSOEVER. Anyone have any idea what's going on?
