- What bind listening? (Can you see it with netstat?) - What port is it listening to? - What errors (if any) are in the error log? I'm afraid your question really isn't a specific FreeBSD problem. You might have better luck on the BIND mailing list. ~Paul On Wed, Jul 04, 2012 at 06:43:00AM

how to correctly distinguish broadcast udp packets vs unicast (socket, pcap or bpf)?

2012-07-04 Thread Budnev Vladimir
Good day to all. What is the correct way to distinguish udp packets that obtained by application and were send on 255.255.255.255 ip addr from those that were send to unicast ip? Seems it is impossible with read/recvfrom so we'v made that with libpcap. It coul be done with directly bpf api
