A master server maintains a list of all running Doomsday Engine servers (jDoom, jHeretic, jHexen) on the Internet. The list of servers can be viewed using a web browser (public servers) or retrieved in Doomsday's Client Setup screen using the "Get From Master" button.

Console variables related to the master server:

server-public (0)

If nonzero, an announcement will be sent to the master server whenever running in server mode.

net-master-address (www.doomsdayhq.com)

Location of the master server.

net-master-path (/master.php)

File name of the master server script.

net-master-port (0)

TCP/IP port where the master server can be contacted on its host. Zero is the default and means that port 80 (HTTP server) will be used.

Console commands related to the master server:

net servers

Retrieves the list of public servers from the master and prints it in the console.

net mconnect index

Connects to the public server index based on the information received from the master.

net announce

Immediately sends a server announcement to the master server. Public servers automatically send an announcement every two minutes.

If you're behind a firewall, see the F.A.Q. to see which ports DirectPlay will be using so you can allow traffic through them.

Notes

Please report bugs encountered during multiplayer games.

The network code is slowly being improved. At the moment it may appear a bit buggy. Unfortunately it seems that debugging the netcode is one of the most time-consuming tasks in the project and thus progress is sometimes a bit slow.

If you don't know a reason to do otherwise, use the port number zero when playing with the TCP/IP protocol. If you're a client and behind a firewall, open any port you wish and then set its number in the TCP/IP setup screen. You shouldn't use a port number that you use to connect to the master or any server, though (i.e. choose an unused port number).
