Hi All, I tried posting this to freebsd-questions, but I have received no reply. So I thought I would try it as a bug (and the ISP list too :), as that is what it appears to be to me. I am not subscribed to this list, so if you could reply directly I would appreciate it :) Anyway .. here is the problem: I can't seem to find a reason for this.. but if I graph the values of fxp0 using netstat -bin, like this: Name Mtu Network Address Ipkts Ierrs Ibytes Opkts Oerrs Obytes Coll fxp0 1500 <Link#1> 00:02:b3:bc:12:7c 3417242 0 232992484 3997590 0 764014344 0 and IPFW-2 rules like this (I also tried ipfw 1, and ipf): 00100 388827 18466235 count ip from any to any in via fxp0 00101 454678 80243192 count ip from any to any out via fxp0 both with the same version of MRTG, the netstat version matches what my provider tells me I am using, but the one using ipfw values is always 50 - 200 kbits/sec off. Does anyone know why? I am stumped :( I have tried using both ipfw 1, and ipfw 2 (counting only layer 3, and only layer 2, and both types (which was way off) of packets).. and I have been unable to solve the problem :( The other odd thing being, it seems to be traffic that is maybe not IP based.. because the graph on the uplink of the Cisco switch behind the firewall in question does not see the traffic ethier.. but the Cisco 6509 in front of it sees it.. :/ Please let me know if you have any ideas :) Thanks in advance :) Dale. -------------------------------- Dale Corse System Administrator Wolfpaw Services Inc. http://www.wolfpaw.net (780) 474-4095 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
