Important:

GeoLite2-City.mmdb file must be present in your $HOME directory (that is: /Users/<yourusername> for MacOS -OR- /home/<yourusername> for most Linux distro)

For Linux's root user, your $HOME directory usually is /root

For Windows, you'll need to re-compile geoip-check.go file and modify the source path to windows %UserProfile% directory
