Hi,

I was following the lecture about making the mac_changer.py script more secure by doing the:

subprocess.call([“ls”, “-l”])

instead of

subprocess.call(“exit 1”, shell=True)

and i get a traceback errror please see image below:

None of the screenshots above are loading, please send them again.
Also can you please show us the code? and are you using the custom Kali I made for this course?

Hi Zaid,
