Arpspoof is a script that will allow you to setup an arp spoofing / redirect attack on a switched and routed network. The script will setup iptables for you, perform sslstrip, and even update the information within the dump file on the screen so you can see what is happening in real time. The script does require that you run it within a system that has sslstrip, and arpspoof installed. Once the applications are in the system you can simply call arpspoof to do your bidding for you.
