                          I'm trying to run Rygel , a UPNP media server, on a headless Fedora 20 system. I installed Rygel, and created a dedicated user and systemd unit for it. Rygel starts but it is not listening on the port I asked it to. I think this is because it fails to get a list of network interfaces from NetworkManager. How can I give it permission to talk to NetworkManager over DBUS? 

**NOTE:** Both NetworkManager and dbus-daemon are confirmed running.

Output from starting Rygel:

    Feb 02 19:13:08 inspiron systemd[1] : Starting Rygel DLNA server...
