I recently started experimenting with ettercap, however, I quickly noticed that when I try and arp poison targets they can almost never communicate with each other.
Is this normal?
My computer is a macbook air with 1.4 Ghz cpu (Core 2 Duo). When I checked the execution cap it was around 50%.
What can I do to make arp poising usable? I need to give a presentation on this soon.
