In my point of view, it should scan all decks in my LAN, right ? Am I doing
something wrong ?


2008/4/9, DePriest, Jason R. <jrdepriest () gmail com>:

What happens if you point it at the broadcast address for your local
network?

If I point it at 192.168.51.255 I get the same thing you do because I
can't get to that address.

If I point it at my own .255 address (I am in a class C), it works
fine.  I still don't get a loop.

I've attached a -vvv -d9 output of my scanning a valid .255.
