;) Your Welcome Bro

When I write : root@host:~# python execute.py

give me: python: can't open file 'execute.py': [Errno 2] No such file or 
directory

what should i do ?

You have to change the working directory to the Fern-Wifi-Cracker folder..

The you execute the:  python execute.py

root@host: cd /opt/Fern-Wifi-Cracker

root@host: python execute.py

I get this:

mmontero@ubuntu:~/Fern-Wifi-Cracker$ python execute.py
Traceback (most recent call last):
  File "execute.py", line 8, in <module>
    from PyQt4 import QtGui,QtCore
RuntimeError: the sip module implements API v9.0 to v9.1 but the PyQt4.QtGui 
module requires API v8.1

What should I do?
