for this you need :1. admin / root access on your machine to see all the traffic that is going through the wire 2. if you are connected using a hub with a ethernet lan card then all you need is to put your network card in promisc mode3. if you are using switches then you have do create a braodcast storm to degrade the switch to act as a hub
arp poisining is less "brute force", but only gives information of traffic between 2 hosts
4. if you are connected using a modem / isdn card then you need a tcp scanner - there are many ones one the net - this will not work for sniffing traffic but you will get a pretty good idea about the hosts around you
