A Linux kernel bug? "pcap_lookupnet()" just does the standard SIOCGIFADDR and SIOCGIFNETMASK calls, which should work. You may have to trace through the "pcap_lookupnet()" code to see what the SIOCGIFADDR and SIOCGIFNETMASK calls return. What version of the kernel is on your machine? - This is the TCPDUMP workers list.
