KDX Server Reporter
From DoomWiki.org
The KDX Server Reporter is a daemon service announcing hosted games to The Universal Master Server (UMS). To keep the entry of the hosted game server alive, the Server Reporter service sends continuously heartbeats to UMS. The game server list, which is maintained that way by UMS, can be fetched using a tool like the KDX Game Browser. Technically, that UMS list is consisting of IP addresses, which then are simply used by the Game Browser to query the corresponding game server hosts. On that game server hosts, the Server Reporter listens for these queries to respond to them with details about the hosted games, such as source port, IWAD, PWAD, Level, deathmatch game mode. The KDX Server Reporter was available in a few different variations, one implemented an additional launcher, so game servers could be set up quick and easy using a GUI.
