Hi! I am trying to run the python file over repl.it but I keep getting this error.

"ERROR: Could not start server, is another program on udp:53?"

@Epicloudygamer you must be able to become root in order to utilize any ports from 1024 and below. As DNS uses port 53, it requires root to run and repl.it does not provide root users on its service. You will have to run the script using your own server or via another service provider. I recommend Google Compute since I believe they give you some free credit if you are a first-time user.

If you are using Linux it's likely you have some service listening on port 53, such as systemd-resolved. To run FakeDNS, you will need to stop this service using sudo systemctl disable --now systemd-resolved.service
