  *  Connection Refused / "Duplicate ID"

If you get a line a bit like:

<code>New client connection refused: Duplicate ID (a33f62d8).
</code>
You probably have copied your [[doomsday]] installation to/from other computers on your local network or copied them to a friends computer for Internet gaming?

The problem is caused by the [[client_id_number]] being stored in the file //Run/jDoom/Client.ID// (in versions prior to 1.9) and in //Snowberry/Runtime/Client.ID// (In version 1.9 and above.) Delete it (on the clients) and the error will disappear as Doomsday automatically recreates the file on startup.

[[version_1_9.0-beta5]] supports the command line option //-id// for specifying the client ID on the command line.

The server requires a unique ID number for each client. The ID number is stored in the Client.ID file. If you copy a Doomsday installation from one computer to another, the ID number file is copied as well. This means when the second installation tries to connect to the first one, a duplicate ID error is reported and the connection is aborted. To fix this, you'll need to delete the Client.ID file from the copied installation. A new ID will be automatically generated when you start the game.
