ParticipantHello,
I was following along with writing variables, when I updated the new mac address variable and ran the script to assign, I can see that the print displayed the correct new mac address, but it did not update.
I ran the process manually in terminator and got a message stating “Cannot assign requested address”.
I’ve tried a few different strings with no results. Any idea why this is happening?
After the first initial change it will not let me change it again…

ModeratorHi Jay!
This looks like a syntax error.
Can you share your code please?Thanks!

Participant`There should be a new tutorial for python 3 because it’s really head scratching trying to figure out things ourselves online. I ran this code exactly as it was taught in the tutoring but it’s giving me error.the error is at the bottom.
#!/usr/bin/env python
import subprocess
import optparsedef get_argument():
parser=optparse.OptionParser()
parser.add_option(“-i”, “–interface”, dest=”interface”, help=”interface to change its Mac address”)
parser.add_option(“-m”, “–mac”, dest=”new mac”, help=”New Mac address” )
return parser.parse_args()def change_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”])(options, arguments) = get_argument()

ModeratorHi!
You are missing a comma between “hw” and “ether”.Change it and let me know how it goes!
