for macOS and Linux.

• YAML configuration for SSH tunnels and port mappings.
• One supervised system ssh process per mapping.

  • stop
  • restart
  • shutdown
• enabled: false support for disabled tunnels.
• Collision detection for occupied local ports.
• Optional same-user port reclamation.
• Unix-socket daemon IPC.
• Status reporting for connecting, active, backing off, error, and
  stopped mappings.
• Graceful shutdown:
  • SIGINT
  • 2-second grace period
  • SIGKILL fallback
• macOS LaunchAgent integration.
• Faster SSH transport failure detection using:
  • ServerAliveInterval=5
  • ServerAliveCountMax=2
