I have read many tutorials on ettercap and seen many videos. So I've tried to arp poison my lan. Everything goes smooth, but when I use the ettercap plugin chk_poison it comes back "chk_poison: No poisoning at all ". When I open wireshark to see whats going on it looks like the poising has worked on my router as well as my target .
Code:
	ARP	192.168.2.1 is at 00:11:22:33:44:55 (duplicate use of 192.168.2.100 detected!)
Code:
ARP	192.168.2.100 is at 00:11:22:33:44:55
