I would need data on source and destination IP address and port. > We use this for traffic engineering. you have several alternatives, but one is to use dummynet with dynamic pipes ipfw pipe 1 config mask all buckets 256 ipfw add pipe 1 ip from any to any and then ipfw pipe 1 show will show you per-flow traffic (the number of flows you can monitor is the 'buckets' times the sysctl variable net.inet.ip.dummynet.max_chain_len which defaults to 16. I think you can raise buckets to 1K, and the sysctl var. to any value you want. cheers luigi -----------------------------------+------------------------------------- Luigi RIZZO, luigi@iet.unipi.it .
