I am trying to install and work with GenieACS (an openSource auto configuration server). I followed this instructions and was able to successfully install it. I need to bring that tool now to life and make the first connection with a CPE. Is there someone who is already working with GenieACS and can tell me which files should i modify (where/how) in order to get GenieACS running?
This question is too broad to be answered here. Even the guide you followed is outdated(!)
I wrote a guide (It's going to be outdated in some months, I'm currently developing the new one for Debian 8) but you can still use it.
The working guide is here: https://github.com/zaidka/genieacs/wiki/GenieACS-v1.1.x-installation-in-Ubuntu-14.04-Server
