uHub is a Direct Connect hub server for ADC and ADCS networks. Its project describes an event-driven, single-threaded architecture aimed at predictable resource use, with IPv4 and IPv6 support, TLS, access control, and an extension system.
ADC clients use uHub as the meeting point for chat and file searching. Client-to-client transfers do not pass through the hub, so hub capacity and peer transfer capacity are separate operational concerns.
It is a server to operate deliberately, not a substitute for a client. Before opening a public hub, decide the endpoint, certificate ownership, access policy, moderation model, logging policy, monitoring, and rollback process.
ADC And ADCS Operation
Choose the protocol address users will publish and verify it with a compatible client. ADCS adds TLS, so the hostname, certificate, port, and client trust path must agree. A successful TCP connection alone does not prove that a client can complete the hub login.
Operations And Extensions
- Review the configuration reference before changing listener, identity, access-control, or logging settings.
- Keep TLS keys readable only by the service account and test certificate renewal before expiration.
- Use plugins only after reviewing their code, compatibility, permissions, and failure behavior.
- Keep a small operational record of the active configuration and each enabled extension.
- Use logs and metrics to investigate a disconnect before restarting a production hub.
Official uHub Resources
The upstream site, documentation, and source repository are the authoritative places to confirm supported options and release-specific behavior. Read the documentation that matches the installed release before relying on an example from a different version.
