Directory Client Protocol

Core protocol is used as usual. Dirserv specific c2s/s2c protocol.

Continuum sends a sync request and SubSpace doesn't. The list request is sent as reliable. On the traditional directory servers (not catid's), traffic is always encrypted, even if you send a null encryption key.

Directory servers listen on port 4990 for client connections.
