Promiscuous mode in NIT

I am playing with NIT, and I am having a problem with promiscuous mode
reading.  The machine is a Sun 3/60C running 4.0.3.  The problem is that
even in promiscuous mode (as root), I don't see any packets with the
source address of my machine (the machine the program is running on).  I
would like to be able to see ALL packets on the network, including those
generated by my machine...

I am currently using the PF module to do filtering, but it seems to work,
so I don't think that's the problem.  I can set the filter to pass packets
containing a source address of other machines on the network, but I never
see packets from the machine the code is running on.

The basic code was taken from the NIT man page, so it should be correct,
but I'm new to NIT, so I might have screwed something up.
