hi all, we're trying to build pfsync centric accounting system. Our plan is to use pfflowd to emit NetFlow datagrams to work them out within flow-tools. E.g., using flow-receive we get SOMEFILE which can be further proceesed by flow-export or alikes. We found that SOMEFILE gets occassionaly updated. man pfsync says that state infomation refreshment is condensed which is controled by maxupd parameter to ifconfig (equal by default to 128). For some reason FreeBSD (5.3-stable) version of ifconfig has no maxupd option, OpenBSD does. So we believe now, pfsync iface in that incarnation of FreeBSD has no way to change this parameter and hence to fine tune state information update frequency. Is that so? Vlad
