Hi soxrok2212,
thank you for you reply.
Yes, I know, but I think these versions are different.Keep in mind, reaver and pixiewps are included by default in Kali 2.0. There is a version of wifite included as well that I believe supports the pixie dust attack, but it is not aanarchyy's version.
They not only accept different command parameters but they also run differently. At least as far as I can say, after testing them on the same system with the same hardware, on two separate installs.
One with original Kali 2.0 files exclusively and one with Kali 2.0 after installing and applying modifications like aanarchyy's version and so on.
