Randomize Mac Address In Linux With Python Script

Kali has macchanger installed already but for Mint 18 you will need to install

Code:

sudo apt install -y macchanger

Tested in Kali Linux but fails inside virtual box im still working on this, check below for updates!.

Code:

#!/usr/bin/env python
# (c) J~Net 2017
# python fastmac_all.py wlan0

import random
import pwd
import os
import sys
import re

if len(sys.argv)<2:
    os.system("clear")
    os.system("ifconfig")
    adaptor=raw_input("Choose Adapter & Press Enter To Continue. ");
    
else:
    adaptor=sys.argv[1]

def randomMAC():
    return [ 0x00, 0x16, 0x3e,
        random.randint(0x00, 0x7f),
        random.randint(0x00, 0xff),
        random.randint(0x00, 0xff) ]

def MACprettyprint(mac):
    return ':'.join(map(lambda x: "%02x" % x, mac))

if __name__ == '__main__':
    newmac = (MACprettyprint(randomMAC()))
   # raw_input("Press Enter To Start Mac Changer...");
    os.system("sudo ifconfig " + adaptor + " down")
    combined = ' '.join([newmac,adaptor])
    os.system("sudo macchanger -m " + combined + "")
    os.system("sudo service network-manager restart")
    os.system("sudo ifconfig " + adaptor + " up")


I have made this so if you forget to put adapter (eth0 or wlan0) you will be shown a list and asked which adapter you want to change mac address on!

If used inside virtual box you will need to restart to get internet access back but on an actual machine (native) it will work 100% fine with no loss of internet!
