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.

Either a dereference of pointer that doesn't point to a valid
address, or possibly an attempt to store through a pointer that
points to a valid address in a read-only region of the address space.
There does not exist a higher-level description of the cause of a
"segmentation fault". A lot of different problems, which have only
the item in the previous paragraph in common, can cause a
segmentation fault. I suggest you try to use a debugger to determine
what code is getting the segmentation fault.
