Surely you jest! :> :> I wish I were. : :I was talking about 20kpps of LEGITIMATE ICMP traffic :-) Oh. no. 20Kpps of illegitimate ICMP traffic. It would be pretty hard to get even 10pps of legitimate ICMP traffic. Our most heavily loaded web server only generates 0.5 pps or so in ICMP packets and receives maybe 1 pps in ICMP. -Matt Matthew Dillon Engineering, HiWay Technologies, Inc. & BEST Internet Communications & God knows what else.
