Door Hub
Door Hub lets several BBSes share one set of door games. Callers on every member BBS play in the same games as each other, as if the games ran on their own board. It works the same way as DoorParty: each member BBS runs a small connector, and the connector sends callers to the hub through an encrypted SSH tunnel.
Door Hub is free software under the GNU GPL (version 2 or later). It runs on Linux (x64 and arm64) and Windows (64-bit), and works with Synchronet; Mystic and other BBS programs can join a hub through RLogin.

How it works
caller --> member BBS --RLogin--> connector ==SSH tunnel==> hub --RLogin--> door BBS
(any BBS) (on the member's PC) (doorhub) (Synchronet with the games)
- A caller picks a hub game on their own BBS. The BBS opens an RLogin connection to the connector on the same machine, with the caller's name, a password made for that caller, and a game code.
- The connector puts the BBS's system tag in front of the name, for example
[KAL]Heisenberg, and passes the connection to the hub through an SSH tunnel. Each member BBS has its own hub account. - The hub checks the account and the tag. The first time it sees a player it makes them a user on its own Synchronet BBS (the door BBS), called
Heisenberg (KAL). - The hub logs that user in to the door BBS and starts the game straight away. When the game ends the caller is back on their own BBS (or back at the hub menu, if they came through it).
Callers never log on to the hub themselves and never see a password. Member BBSes only make outgoing connections, so they don't need to open anything on their router.
