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.
