[dsc] Multiple interfaces

[David Soltero]

Hi,

No, I don't have a 'bpf_program' line, since the one we tried did produce any results.

I am under the impression that yes, we are only seeing traffic for the last interface on the config.

It is supposed to work they way that you want.  I think you should
be getting data from all interfaces, but its been a while since
I've tested such a configuration.

The code calls pcap_open() for each interface and then uses
select(2) on the pcap file descriptor to multiplex.

you don't have more than one 'bpf_program' line, do you?

If you re-order the interface lines do you then get only traffic
from the new last interface?
