Use this page when a guide uses a term you do not recognize.

| Term                       | Meaning                                                                                                      |
| -------------------------- | ------------------------------------------------------------------------------------------------------------ |
| **FRP**                    | The official `fatedier/frp` reverse-proxy/tunnel engine used by this project.                                |
| **FRP Auto Deploy server** | The Linux public entry point running `frps` plus the enrollment/management layer.                            |
| **Client**                 | A remote machine running `frpc` and the FRP Auto Deploy client state/management identity.                    |
| **CLIENT ID**              | Immutable machine identity used by the server for canonical administration.                                  |
| **Label**                  | Human-friendly client name. It can change without changing CLIENT ID.                                        |
| **Hostname**               | The operating-system hostname reported/displayed for a client; not canonical identity.                       |
| **Tag**                    | Administrator metadata used to classify a client.                                                            |
| **Service**                | One published TCP target, such as SSH or a web application.                                                  |
| **Service ID**             | Stable identifier for a service on a client, such as `ssh` or `web-admin`.                                   |
| **Target host / port**     | Where the FRP client forwards the connection, for example `127.0.0.1:22` or `10.10.20.30:443`.               |
| **Public service port**    | Internet-facing TCP port assigned to a service on the FRP server. It is treated as a persistent reservation. |
| **Enrollment**             | Secure first-time pairing of a client with the server.                                                       |
| **Enrollment Code**        | Short-lived secret used during manual enrollment.                                                            |
| **Bootstrap Ticket**       | Short-lived secret used by Zero-Touch enrollment.                                                            |
| **Zero-Touch**             | Onboarding method where the server prepares the profile and the remote user runs one generated command.      |
| **Allocator**              | Server-side enrollment/management HTTPS component that coordinates enrollment and service-port assignment.   |
| **Project private CA**     | CA maintained by FRP Auto Deploy to establish/verify management HTTPS trust.                                 |
| **FRP token**              | Credential used to authenticate the FRP tunnel; separate from enrollment/management credentials.             |
| **Direct mode**            | Default server mode with FRP control and enrollment HTTPS exposed on separate public endpoints.              |
| **single-443**             | Enterprise mode that carries enrollment HTTPS and FRP control/WSS through public TCP/443.                    |
| **Public hostname**        | Optional DNS alias for user-facing published-service access.                                                 |
| **Disable**                | Stop a service temporarily while keeping its public-port reservation.                                        |
| **Release**                | Return a public service-port reservation to the pool.                                                        |
| **Revoke**                 | Block a management identity or active enrollment credential; does not mean release.                          |
| **Doctor**                 | Read-only `frpctl` diagnostics that checks installation, trust, state, services, and network consistency.    |

<Note>
  The three most important distinctions are **CLIENT ID vs label/hostname**, **disable vs release**, and **FRP token vs enrollment/management credentials**.
