Hi, I have a python server with twisted framework running 24x7. I want to have a config file to setup accepting local computer requests or remote computer requests. If the config file exists, it only accepts local computer request, does not accept requests from other computers. If the config file does not exist, it accepts requests from any computers. Is there any easy way to do it ? Best regards.
