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. --=20 Jon Simola Systems Administrator ABC Communications
