Hi Jeremie. Please tell me more about your problem: is it that tcpdump cannot attach = to device, or it shows no packets when you are sure there is traffic on = the gif(4) interface, or something else? If there is some error report - = send it here. Please check that you have free bpf device :-) . What = version of 4.x are you running? On my 4.9 system if_gif.c has references = to bpf_mtap in both _input and _output routines. That should work.

Everything works well except I can't use tcpdump(8) on the gif(4). IIRC it's a well-known problem - I already saw this topic here but can't find these posts again - but I cannot understand why it doesn't work since if_gif.c in RELENG_4 has bpfattach(), bpf_mtap2(), ... Is it supposed to work or not ? If not, does it work on RELENG_5 ? My very -CURRENT laptop succeeds in opening bpf(4) on a gif(4) = interface.
