Opening a live capture as root (using sudo), on a vmware bridge device on Linux 2.6.27, using a timeout of 1000ms. I'm seeing pcap_next() and pcap_dispatch() getting stuck reading, no timeouts are occurring. Is there a robust and efficient way of reading packets that won't block forever like this? I'm doing this from that c# library so while I've thought of using poll() on the devices file descriptor I wanted to avoid doing low level calls like this so the code would work with winpcap/pcap on windows/linux platforms.
I wrote a simple c app, using an example from http://www.tcpdump.org/pcap.htm, so I had a really simple way of reproducing the issue. I can post this if it would be helpful to confirm that I'm not doing anything really dumb. Chris - This is the tcpdump-workers list. Visit https://cod.sandelman.ca/ to unsubscribe.
