Hello everyone, I have searched and searched but have had no luck with this error.

I installed ettercap as shown in the thread below but could not install the the extra two links listed since they were for x86.

It will search for all the hosts on the network and seems to arp but gives that error and i know it isn't fully working because of some comparison test I've done with BT4 R2.

Any help would be much appreciated.
