: Have you compiled bpf support into the kernel?

: pseudo-device	bpfilter	4

: will add support for 4 bpf devices (/dev/bpf[0-3]).

: Try looking on an Ultrix system 8-) (As stated on the man page, the
: /dev/bpf? devices perform this function on BSD systems).

I do have bpf support compiled in. I can run tcpdump on sl0 but when I

Thanks,
