hi vern
thanks for your statement.
i looked at the c-code. i runned it on different machines and
on various interfaces. bro still drops most of the packets
when i force it to listen on two interfaces.is it a libpcap problem?
a bro problem?
a linux problem?I believe it's a Linux problem. We do this under FreeBSD in two different
ways, either merging the interfaces in the kernel into one logical
interface (via a custom patch), or at user level. While the in-kernel
version performs better, the user-level one isn't a disaster like you
describe.
i also thought about bonding the interfaces and maybe it won't be a problem.
but we plan to introduce Luca Deri's PF_RING kernel patch in the future and
then interface bonding won't be possible any more.
I also recall hearing others mention that multiple interfaces under Linux
do not work well in general. I don't use Linux, though, so can't comment
more directly.
do you know other linux software which allows to listen on two interfaces?
so that i can use it for testing?
tcpdump only allows to listen on one interface or on all (any).
thanx
