What happens when you try to capture on an interface that's already
in promiscuous mode?
---> When I try to capture packets on an interface that's already in
promiscuous mode, tethereal just prints -
** WARNING **: radius: Could not find the radius directory
Capturing on eth1
A tcpdump on the same interface confirms that there is traffic on eth1, but
tethereal doesn't see it.

Are you doing this on HP-UX?
---> I'm using ethereal-0.10.12 on Red Hat Linux 7.3 on x86 platform.

Thanks,
