I'm currently using a simple bpf program which matches the packets directly to a linear table. Does per-ip statistics and apparently could handle quite a bit more network load. The other extra goodie is that it can sit on a hub and watch by-flying traffic instead of packets having to go through the statistics-gathering host. > skipto is at present not very efficient, however as I said above. > that is abount to change. Using skipto to optimize ipfw tables is too much manual labor, I will wait for radix tree implementation or something like that :) -- Heikki Suonsivu, T{ysikuu 10 C 83/02210 Espoo/FINLAND, hsu@clinet.fi mobile +358-40-5519679 work +358-9-43542270 fax -4555276 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
