This means If I read this correctly, pcap will sometimes wait forever until a packet appears, which I don't actually mind because it's actually the behaviour that I'm expecting. What is really odd is that even when packets ARE arriving, pcap_loop just sits there, lets the packets pile up, and then shows all the messages at once... then it blocks again for a while, even as I send messages from the other computer, just to show them all at once again, and so on... > you'll probably find yourself either going > multithreaded or using I'm actually going multithreaded, but I'd expect a packet to show up immediately, so I can process it and perform the routing in a timely manner, rather than delivering a packet a minute after it was sent.
