# SSH Tunnels

susshi supports SSH local-port-forwarding tunnels, configured per-server and managed interactively from the TUI.

## Configuration

Define tunnels in the YAML config at any level (defaults, group, environment, server). A `tunnels` list at a lower level **replaces** the one inherited from above.

```yaml
servers:
  - name: db-01
    host: 198.51.100.11
    tunnels:
      - local_port: 5432
        remote_host: 127.0.0.1
        remote_port: 5432
        label: "PostgreSQL"
      - local_port: 6379
        remote_host: 127.0.0.1
        remote_port: 6379
        label: "Redis"
```

Each entry produces: `ssh -L <local_port>:<remote_host>:<remote_port> -N …`

Fields:

| Field | Required | Description |
| --- | --- | --- |
| `local_port` | Yes | Port bound on `localhost` |
| `remote_host` | Yes | Host as seen from the remote server (usually `127.0.0.1`) |
| `remote_port` | Yes | Port on the remote side |
| `label` | No | Display name shown in the TUI tunnel list |

> **Note:** Tunnels are not available in `wallix` mode — the bastion does not allow arbitrary port forwarding.

## `keep_open`

Set `keep_open: true` at any config level to automatically reopen the TUI after a connection closes. Useful when you want to run a tunnel, disconnect, and immediately pick another server.

```yaml
defaults:
  keep_open: false  # default
```

## TUI Tunnel Manager

Press `T` in the TUI to open the tunnel manager overlay.

Actions:

| Key | Action |
| --- | --- |
| `Enter` | Start or stop the selected tunnel |
| `a` | Add a new tunnel (user override) |
| `e` | Edit the selected tunnel |
| `D` | Delete the selected tunnel |
| `Esc` | Close the tunnel manager |

Active tunnels show a live status badge next to the server name in the tree.

## User Overrides

Tunnels added or edited through the TUI are stored as **user overrides** in `~/.susshi_state.json`. Overrides persist across restarts and are merged with config-defined tunnels at runtime. Deleting an override reverts the server to its config-defined tunnels.
