Just packaged it

Ettercap 0.7.3
Quickly tested on OS2008.
No https support at the moment.

I don't have a 770, depending on your OS and libraries, it might or might not work.
If not, wait that somebody does the same job as me. It's standard packaging, just quilt is needed for libpcap0.8

Additionnaly, there should be scapy somewhere on internet. It's very powerfull, you might have a look.
