Settings

Settings uses a sidebar/detail layout. The sidebar lets you add, delete, and reorder tunnels; the menu uses the same order. The detail pane is autosaved after edits.

Tunnel configuration

Field	What it does
Name	Label shown in the menu and settings list.
Host Alias	The SSH config host entry to connect to.
Control Path	Socket path for the app’s SSH master connection.
Health Check	Seconds between automatic connectivity checks.
Max Backoff	Maximum delay between reconnect attempts.
Start at Login	Connect this tunnel when the app launches.

Startup Check

An optional TCP host and port gate for Start at Login. The app retries until a TCP connection to that host and port succeeds — useful for VPN-only endpoints. See Health Checks & Reconnects.

SSH Config Forwards

TCP ports derived from ssh -G <alias>. Add optional service labels here for clearer localhost port pills (for example API 1443). To change the actual forwards, edit ~/.ssh/config and choose Refresh Forwards.

If one of these local ports is already in use when you start the tunnel, the app offers a session-only remap onto a free port instead of failing — see Port conflicts.

Quick Forwards

App-managed remote ports with automatically assigned local ports. See the dedicated Quick Forwards guide.

Logging

Log Level sets the global minimum level for unified logging, the persistent file log, and the in-memory debug-log export. Use Debug before reproducing subtle timing or reconnect issues. See Debugging & Logs.

Run Diagnostics

Validates the saved or drafted tunnel configuration before you start it. It checks:

• Required fields
• ssh -G resolution
• SSH config forwards
• Quick Forwards with assigned local ports
• ControlPath collision safety
• Local port availability

When the tunnel is already connected, ports held by that tunnel’s own ssh process are treated as expected rather than as conflicts.
