Most of it I get or know how to find the answer but there is one thing that is still a puzzle. I have a pipe configured as: ipfw pipe 2 config bw 768Kbit/s queue 20Kbytes When I use `ipfw -s 4 pipe 2 show, one bucket is shown: 00002: 768.000 Kbit/s 0 ms 20 KB 1 queues (1 buckets) droptail mask: 0x00 0x00000000/0x0000 -> 0x00000000/0x0000 BKT Prot ___Source IP/port____ ____Dest. IP/port____ Tot_pkt/bytes Pkt/Byte Drp 0 tcp 12.###.##.77/80 88.###.##.175/2200 10565 8421549 0 0 103 I understand that there is only one bucket but how are the source and destination ip addresses and ports chosen to be displayed from all that are routed to the pipe? Do they have any significance? While I'm at it this pipe has a 768 Kbps bw limit and is currently running at less than 250 Kbps. Why are packets still being dropped at the rate of about 1%, fairly consistently?
