Hello,
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…
This is the message that displays:
/root/PycharmProjects/hello/venv/bin/python /root/PycharmProjects/hello/mac_changer.py
interface > eth0
new_mac > 00:11:22:33:44:55
