    Uh, you're asking it to wait forever to see a packet. I don't see a
    #define in there for BUFSIZ, so you might be asking it to catch zero
    bytes. And what is the "totally unrelsated message"?

    I'd try using pcap_loop() or friends so you can catch and examine more
    than a single packet.

    And don't forget to call pcap_close() at the end, I'm not sure how
    polite pcap is about leaving dangling bpf devices.
