Hi, nice to see a shiny new release of libpcap and tcpdump so soon.
Out of interest, is the "tcpdump: unsupported data link type
USB_LINUX"
bug/issue resolved when trying to capture USB traffic on a Linux box?
If you mean "if I try to capture USB traffic on a Linux box, and don't
give the '-w' flag to get it to write the raw traffic to a file, will
it print 'tcpdump: unsupported data link type USB_LINUX'?", the answer
is "yes", because nobody's written a USB printer routine for tcpdump,
so it *can't* handle USB traffic in that case. If that's the problem
in question - which is more of a "lack of a feature" than a bug - it's
still there.
if you mwan "if I try to capture USB traffic on a Linux box, and *do*
give the '-w' flag to get it to write the raw traffic to a file, will
it print 'tcpdump: unsupported data link type USB_LINUX'?", the answer
is "no", because it just dumps the traffic out without interpretation,
regardless of whether it has a printer for the link-layer type or not,
and thus can handle USB traffic or any other type of traffic. If
that's the problem in question, it's fixed.
