I don't use Pali's script (it is really well written but to use it I will need to change a lot). How did you try to run it? From reading the code you need to pass an option for the action you would like to execute. e.g. to run: #./packet-injection.sh load #./packet-injection.sh enable to restore: #./packet-injection.sh unload But if this is too complicated you can just use what you had before just point to the new location. Let me know if I didn't understand the question.
