Thanks for the info...I use ethereal as well as tcpdump quite
frequently, but I need something a little different here.

I don't need to worry about ``sniffing'' as it's normally used,
because the FBSD box will be put right in-line between the affected
box and the core network switch, so ALL packets will travel right
through the box so I can manipulate every single packet as required.

It was suggested (off list unfortuneatly) to check out bandwidthd and
ipaudit.

I'm going to give bandwidthd a try, as it looks very close to what I
want.

Tks,

STeve
