hi,
I use FreeBSD 4.2 stable + bridge + dummynet + ipfw.
I would like to calculate the bandwidth of each
authorized IP source flowing through the bridge from a
user program.
As this bandwidth calculation should be done very often
(10 to 20 times per second) I first tried to use the if_data
structure from sysctl. But it seems the packet counter is
only incremented for packets destinated to the specified
interface, and moreover I wouldn't be able to separate the
incoming flows depending on their source addresses.
Anybody has an advice on the best way to achieve this
calculation ? what about the counter capabilities of ipfw ?
Moreover, concerning the bridge, I was wondering if
there is a way not to put a third interface in promiscous
mode. As this third nic exists only for management purposes
I don't want it to participate to the bridge in any way.
Thanks,
Roman.
