+### configuration
+
+**Freeradius server configuration:**
+The configuration for the status server is automatically created in the sites-available directory.
+By default, server is enabled and can be queried from every client. 
+FreeRADIUS will only respond to status-server messages, if the status-server virtual server has been enabled.
+To do this, create a link from the sites-enabled directory to the status file in the sites-available directory:
+   #*cd sites-enabled*
+   #*ln -s ../sites-available/status status*
+and restart/reload your FREERADIUS server.
