I need to change the filter condition dynamically.  So I have another

This code works fine on Windows changing the filter condition. On LINUX
if I change a filter condition no packages come anymore through
pcap_next.

There might be a bug in the version of libpcap on that version of whatever Linux distribution you're running. What version of what distribution of Linux (*distribution* version, not *kernel* version) are you using, and what version of libpcap does it have?


As that's not on Windows, this should probably be discussed on tcpdump-workers, so I'm sending it there and setting the Reply-To: header appropriately.
