Hi Sir, I have a problem with this code as I receive this: RuntimeError: maximum recursion depth exceeded while calling a Python object

Can you let me know please what is wrong with my code?

#!/usr/bin/env python

import re
import subprocess
import optparse

def get_args():
    parser = optparse.OptionParser()
    parser.add_option("-i", "--interface", dest="interface", help="Interface to change its MAC address")
    parser.add_option("-m", "--mac", dest="interface", help="New mac address")
    (options, arguments) = get_args()
    if not options.interface:
        parser.error("[-] Please specify an interface, use --help for more info.")
    elif not options.new_mac:
        parser.error("[-] Please specify a new mac, use --help for more info.")
    return options

def change_mac(interface, new_mac):
    print("[+] Changing MAC address for " + interface + " to " + new_mac)
    subprocess.call(["ifconfig", interface, "down"])
    subprocess.call(["ifconfig", interface, "hw", "ether", new_mac])
    subprocess.call(["ifconfig", interface, "up"])

def get_current_mac(interface):
    ifconfig_result = subprocess.check_output("ifconfig", interface)
    print(ifconfig_result)
    mac_address_search_result = re.search(r"\w\w:\w\w:\w\w:\w\w:\w\w:\w\w", str(ifconfig_result))
    if mac_address_search_result:
        return mac_address_search_result.group(0)
    else:
        print("[-] Could not read MAC address.")

options = get_args()

current_mac = get_current_mac(options.interface)
print("Current MAC = " + str(current_mac))

change_mac(options.interface, options.new_mac)

current_mac = get_current_mac(options.interface)
if current_mac == options.new_mac:
    print("[+] MAC address was successfully changed to " + current_mac)
else:
    print("[-] MAC address did not get changed")

Hi!

Can you share a screenshot with the command used to run the code and the result please?

Thanks!

Sorry if you can’t see the image. I cannot figure out how to send them

Hi!

Just upload them to some image hosting service or Gdrive and share the link here.

Greetings!

The access is restricted, can you allow it to anyone who has the link?

Thanks!

Hopefully, the images work now

Hi!

In the get_args function you have used interface as dest value for both options, correct this and try it again.

Greetings!
