Ah, OK. Looking at the docs with nice win32 screen captures, I see why
I did not know what you mean--I had never seen it actually work. At the
moment on a non-BPF-having UNIX, you either a)run everything
non-privileged, and cannot get sniffing permissions at all, or b)run
everything as root, in which case gtk will refuse to even run the
Wireshark GUI, so you never see it.
OTOH, it probably works fine right now under BSDish OS's with
permissions set appropriately on /dev/bpf*.

OK.
Well, how about this. I contend that since the current code is
completely broken for live-capturing on non-BPF-having UNIX, an
incremental improvement (making it basically work, albiet somewhat
lacking) is better than the current state. So, how 'bout a patch that
rather than just ifndef _WIN32, is specifically only enabled for
non-BPF-having UNIXes. That way they would Basically Work, with this
documentable shortcoming, which maybe one day will garner enough
interest to be resolved? Would you accept such a patch?

I understand, and there are probably indeed many better ways for you to
spend your time (either on wider-interest Wireshark stuff, or on a
life!). While this remains an interest of mine, I'll try to help rather
than just complain :-P
Thanks,
