I have a similar problem with promiscuous mode in 0.9.1 under MacOS X.1.2.
When I capture in promiscuous mode, network apps generate outbound traffic
but the packets are never seen "on the wire". This is still occuring *after*
I stop capture, and even exit the Ethereal application. Basically, I have to
"ifconfig down" and "ifconfig up" the interface that I was using for
Ethereal capture. After I do this, I am able to transmit packets on the wire
again.
I understand that this may not be an Ethereal problem, and instead is
probably an issue with the interface driver, but I was curious if anyone has
found a workaround for this, or has even experienced the problem.
