Hello,

Yes, I am using it on a box with two fxps.
It is:
FreeBSD 4.6-STABLE #2: Thu Jul 11 15:13:00 CEST 2002

You won't see too much from that...
4.6 (the above box):
# tcpdump -i fec0 host FE0.GE.BMF-HBONE.bmf.hu
tcpdump: listening on fec0

(193.6.21.133 is the GW and that is I pinged)
# tcpdump -i fxp0 -p host & \
tcpdump -i fxp1 -p host
tcpdump: listening on fxp0
tcpdump: listening on fxp1
And nothing. That's why I said previously it seems that the packets don't
get down to the physycal interface. Or at least they don't get out to the
wire...
However, when I ping the test machine from another one, I get:
Fatal trap 12: page fault while in kernel mode

I will attach a disk onto this machine to its Adaptec controller and will
be able to send you the dumps.
(some people helped me to figure out that most of the RAID drivers in
FreeBSD doesn't implement dump...)
Thanks,
