Python3: Spoof MAC Address: datetime.date(), subprocess.run()

Caution

spoof_mac.py can break a network connection, so users should avoid negative outcomes.

Bang Line

#! /snap/bin/pypy3 starts with a shebang (#!), which functions as a magic number:

Unix or Linux scripts may start with a shebang (#!, 23 21) followed by the path to an interpreter, if the interpreter is likely to be different from the one from which the script was invoked.1

PyPy3 Snap

In Ubuntu, /snap/bin/pypy3 can be installed in the CLI: $ snap install pypy3. python3 can be used otherwise.

Index Daily MAC Address

datetime.date.today().weekday() returns an integer used to index the MAC address of the day from mac_list.

mac_list = [
    "9A:E9:30:BF:99:3E",
    "AA:F4:25:C5:0E:2E",
    "9E:FF:D2:A5:B4:6C",
    "9E:FF:D2:A5:B4:6D",
    "CA:F2:6D:CF:15:67",
    "02:4D:64:22:FE:70",
    "7E:AE:18:B4:32:19"
]

On Saturday, value returned by datetime.date.today().weekday() is 5, which indexes mac_list[5] which returns '02:4D:64:22:FE:70', the MAC address for Saturday MAC address.

Run the Script

$ python3 ~/Applications/py/spoof_mac/spoof_mac.py

Alternative: Shell Script

#! /bin/sh
# spoof MAC address
$HOME/scripts/spoof_mac/./spoof_mac.py

# check network device name with spoofed MAC address
sudo lshw -class network | egrep 'serial|logical name'

gen_mac

gen_mac.py generates a pseudo-random MAC address. The first part of the spoofed MAC address comes from a list of organizationally unique identifiers.
