FlightGear Multiplayer Server

FGMS or FlightGear Multiplayer Server is a standalone network server for FlightGear and licensed under the GPL. It allows flying with other pilots over a network inside FGFS.

Types of server lists that can be configured in a server configuation:

  1. Relay server - the other servers in the network. Each has to have the full list (minus itself) for proper network function.
  2. Crossfeed server - everything the server receives from local users and other servers is forwarded to the crossfeed server(s). Intended for running several connected fgms instances on the same host, e.g. for providing both a tracked and untracked service, without incurring additional external traffic.
  3. Tracker - The server sends a digest update for each local user to the tracker every 10 sec.
  4. HUB - normally Servers do not send packets they receive from a server to other relays. A HUB server sends data from servers to all relays it knows about.

Special callsigns:

  • "obsXXXX" (replace X's with any character you like) allows a connected FlightGear client to view all other MP pilots worldwide (position data and chat messages), yet remain invisible to them and on MPmap.
  • "mpdummy" prevents the pilot from being tracked on FGTracker. Not recommended - if several users use this callsign some will be ignored by the servers. Connect to an untracked server instead.

As of 07/2013, a bunch of folks are working on re-implementing fgms using the Go programming language, for details check out:
