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.

What happens when you try to capture on an interface that's already  
in promiscuous mode?

Are you doing this on HP-UX?
