# Remote access (SSH, tunnels, and tailnets)

This repo supports “remote over SSH” by keeping a single Gateway (the master) running on a dedicated host (desktop/server) and connecting clients to it.

- For **operators (you / the macOS app)**: SSH tunneling is the universal fallback.
- For **nodes (iOS/Android and future devices)**: prefer the Gateway **Bridge** when on the same LAN/tailnet (see [Discovery](/gateway/discovery)).

## The core idea

- The Gateway WebSocket binds to **loopback** on your configured port (defaults to 18789).
- For remote use, you forward that loopback port over SSH (or use a tailnet/VPN and tunnel less).

## Command flow (what runs where)

One gateway daemon owns state + channels. Nodes are peripherals.

Flow example (Telegram → node):
- Telegram message arrives at the **Gateway**.
- Gateway runs the **agent** and decides whether to call a node tool.
- Gateway calls the **node** over the Bridge (`node.*` RPC).
- Node returns the result; Gateway replies back out to Telegram.

Notes:
- **Nodes do not run the gateway daemon.** Only one gateway should run per host unless you intentionally run isolated profiles (see [Multiple gateways](/gateway/multiple-gateways)).
- macOS app “node mode” is just a node client over the Bridge.

## SSH tunnel (CLI + tools)

Create a local tunnel to the remote Gateway WS:

```bash
ssh -N -L 18789:127.0.0.1:18789 user@host
```

With the tunnel up:
- `clawdbot health` and `clawdbot status --deep` now reach the remote gateway via `ws://127.0.0.1:18789`.
- `clawdbot gateway {status,health,send,agent,call}` can also target the forwarded URL via `--url` when needed.

Note: replace `18789` with your configured `gateway.port` (or `--port`/`CLAWDBOT_GATEWAY_PORT`).

## CLI remote defaults

You can persist a remote target so CLI commands use it by default:

```json5
{
  gateway: {
    mode: "remote",
    remote: {
      url: "ws://127.0.0.1:18789",
      token: "your-token"
    }
  }
}
```

When the gateway is loopback-only, keep the URL at `ws://127.0.0.1:18789` and open the SSH tunnel first.

## Chat UI over SSH

WebChat no longer uses a separate HTTP port. The SwiftUI chat UI connects directly to the Gateway WebSocket.

- Forward `18789` over SSH (see above), then connect clients to `ws://127.0.0.1:18789`.
- On macOS, prefer the app’s “Remote over SSH” mode, which manages the tunnel automatically.

## macOS app “Remote over SSH”

The macOS menu bar app can drive the same setup end-to-end (remote status checks, WebChat, and Voice Wake forwarding).
