@pbholmen I would recommend installing from the .deb files if you are planning to use FusionAuth for production. Fastpath is great for exploring and development.

Java is listening on both ports because 9011 is the external port and 9012 is for internal calls. More details here in the configuration reference: https://fusionauth.io/docs/v1/tech/reference/configuration

Per this issue https://github.com/FusionAuth/fusionauth-issues/issues/673

"This is because the services are running interactively and the logging is written to to stdout."

So when you start up your fusionauth instance using startup.bat a cmd window will open up and your logs will be written to that.
