Hi Linh,
I have a problem, and I need your help. I setup and configured domjudge successful. But now, I want to change port of Domjudge (example, when we organize an offline contest, I want to close port on public network, I only open domjudge port for LAN).
So can I change port of domjudge? Default port is 80, right?
It's no problem for DOMjudge to run on any port you'd like. This is just a matter of changing your Apache configuration (look for the "Listen" directive somewhere under /etc/httpd), and make sure you update the URL in your judgehosts' restapi.secrets file to also include the correct port number.
Cheers, Thijs
