Ok, used the script once and it worked pretty bad, something got screwed up since our last version.

1 - Log is saved in root, despite the script telling the user it has been saved in opt/tmp, and vice versa (passwords are saved in opt/tmp, but the script says they are in /root); I'm fixing this in minutes;

2 - Websites are not shown in real time parsing, what happened???

3 - Ettercap is not properly closed, and after the closing of the script victims are not re-arped so the user has to manually enter "q" in ettercap for resetting the network.

EDIT: first point should be fixed now, check this out:

I'm trying it right now...
