I am using Backtrack4 in VM and wanted to play around with IronGeeks old 'Fun with Ettercap' filter. I have followed his tutorial but when I launch
ettercap -T -q -F ig.ef -M ARP /Target/ //
it causes IP conflicks.
I have not edited the etter.conf. Not sure if it needs it.
I have also ran in another shell
echo 1 > /proc/sys/net/ipv4/ip_forward
any ideas why this would be happening?
