Simple python Script to change mac address of linux generate random or enter mac address

import random from subprocess import PIPE, Popen

function for returning terminal command

def cret(command): process = Popen(args=command, stdout=PIPE, shell=True) return process.communicate()[0]

function for genrate mac address random

def randmac(): return [ 0x00, 0x16, 0x3E, random.randint(0x00, 0x7F), random.randint(0x00, 0xFF), random.randint(0x00, 0xFF), ]

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

print(" +-+-+-+ +-+-+-+-+-+-+-+") print(" |M|A|C| |c|h|a|n|g|e|r|") print(" +-+-+-+ +-+-+-+-+-+-+-+")

finding wireless interface name that should start with wl e.g.-wlan0,wlp3s0

infname = cret('ifconfig -a | egrep "^[wl-wl]+" | sed "s/: .*//" | grep -v "lo"')

INTERFACE NAME 6 character so return 6 last character

infname = infname[:6] infname = infname.decode("utf-8")

GETTING MAC Address from /sys/class/net/wlan0/address directory

cmdgetmac = "cat /sys/class/net/" + infname + "/address" crrntmac = cret("cat /sys/class/net/" + infname + "/address") crrntmac = crrntmac.decode("utf-8") print( "Your Current mac address = " + crrntmac + "\nEnter Option to change Your MAC:\n1. Enter MAC address manually \n2. Automatic Random MAC address" ) opt = int(input())

if opt == 1: print("Please Enter Your New MAC address: \nExmple: 46:d2:f4:0c:2a:50")

newmac = input()
print("Please wait changing  mac address..................")

# first turn off wifi
cret("nmcli radio wifi off")

changemaccmd = "sudo ip link set dev " + infname + " address " + newmac
# executing command with new mac address
cret(changemaccmd)
# turning on wifi
cret("nmcli radio wifi on")
# GETTING MAC Address from /sys/class/net/wlan0/address directory
cr = cret("cat /sys/class/net/" + infname + "/address")
cr = cr.decode("utf-8")

print("\nNow Your Current mac address = " + cr)

elif opt == 2: genmac = retrandmac(randmac()) print("Please wait generating new mac address.....................") cret("nmcli radio wifi off") changemaccmd = "sudo ip link set dev " + infname + " address " + genmac cret(changemaccmd) cret("nmcli radio wifi on") cr = cret("cat /sys/class/net/" + infname + "/address") cr = cr.decode("utf-8") print("Now Your Current mac address = " + cr)

else: print("You Have Selected wrong Option")
