SIOCSIFFLAGS Operation not permitted

Question

I am trying to write a python script for MacChanger. This is the script I am using:

import subprocess

subprocess.call(["ifconfig","ens33","down"])
subprocess.call(["ifconfig","ens33","hw","ether","00:11:22:33:44:55"])
subprocess.call(["ifconfig","ens33","up"])

When I run this, I am getting this error:

SIOCSIFFLAGS: Operation not permitted

Answer 1

You need sudo permissions to make changes to the network interfaces. And because you are running the commands in your python script with normal privileges, you won't be able to make these changes. You will have to use sudo. Try this:

import subprocess

subprocess.call(["sudo","ifconfig","ens33","down"])
subprocess.call(["sudo","ifconfig","ens33","hw","ether","00:11:22:33:44:55"])
subprocess.call(["sudo","ifconfig","ens33","up"])
