About:
autossh is a utility that monitors SSH connections and automatically restarts them if they drop. It leverages SSH's built-in monitoring capabilities to detect connection failures, ensuring persistent and reliable access to remote systems. This tool is essential for maintaining long-lived SSH tunnels and sessions without manual intervention.

Key Features:

Monitors SSH connections for failures
Automatically restarts dropped sessions
Supports persistent SSH tunnels
Lightweight and scriptable

Use Cases:

Maintaining persistent SSH tunnels for remote access
Ensuring reliable connections for automated backup scripts
Keeping port forwards active for development environments

Alternatives:

systemd – Can manage SSH services but is more complex to configure for simple tunnel monitoring.
autossh (Go port) – A modern Go implementation, but the original C version is widely used and battle-tested.
