[keycloak-user] Administering keycloak without a local browser

I am trying to work through the Getting Started Guide and not getting far. The machine I am installing on does not have a local browser. The guide says I can add the initial admin user using the add-user-keycloak.sh script. I have done that, but subsequent steps then assume I can get into the console with a browser. Is it possible to continue the set up from the command line or does almost everything require the web interface? After some digging I found a pointer in the mailing list to https://www.keycloak.org/docs/3.0/server_installation/topics/network/bind.... allow me to continue with the tutorial, but I would like to know if there is a simple way to limit access to a few other hosts?
