Hello,
After the lesson MAC changer I was practicing and I try to code the setting of wireless adapter in monitor mode. If I run it I get the error bufsize must be an integer.
Can you help?
Thanks#!/usr/bin/env python import subprocess import optparse def get_arguments(): parser = optparse.OptionParser() parser.add_option("-i", "--interface", dest="interface", help="Interface to change to monitor mode") (options, arguments) = parser.parse_args() if not options.interface: parser.error("[-] Please specify an interface, use --help for info") return options def monitor_mode(interface): print("Setting {} to monitor mode".format(interface)) subprocess.call("ifconfig", interface, "down") subprocess.call("iwconfig", interface, "mode", "monitor") subprocess.call("ifconfig", interface, "up") options = get_arguments() monitor_mode(options.interface)root@kali:~/PycharmProjects/mac_changer# ls
mac_changer.py set_monitor_mode.py venv
root@kali:~/PycharmProjects/mac_changer# python set_monitor_mode.py
Usage: set_monitor_mode.py [options]set_monitor_mode.py: error: [-] Please specify an interface, use –help for info
root@kali:~/PycharmProjects/mac_changer# python set_monitor_mode.py -i wlan0
Setting wlan0 to monitor mode

TypeError: bufsize must be an integerHi Simo!
If you want to use that synthax with subprocess you have to use square brackets as well. Like:
subprocess.call([“ifconfig”, interface, “down”])Let me know how it goes!
