New page

= UPnP Server Notes =
The UPnP service provided by fuppesd is used to serve all the media on a LinuxMCE system to a UPnP client. BUT, right now, the UPnP service does not know, when things change. Whenever media is added to the system, the fuppesd database need to be rebuild.
== Rebuilding UPnP Database ==
To rebuild the UPnP database, the web admin provides the UPnP page under Advanced / UPnP Server. Under Options click on Rebuild Database, to update the upnp database with current list of files in the system.

Hopefully, this will change in the future, and there is going to be a tie between UpdateMedia and the UPnP server.
