guix package -i autossh # Install autossh with Guix autossh -M 0 -o "ServerAliveInterval 60" -o "ServerAliveCountMax 5" -L 4000:127.0.0.1:3306 alexander@remoteserver.org
Autossh is a utility for automatically restarting SSH sessions and tunnels if they drop or become inactive. It's particularly useful for long-lived tunnels in unstable network environments.
See official docs:
Install autossh using Guix:
guix package -i autossh
Basic usage:
autossh [-V] [-M monitor_port[:echo_port]] [-f] [SSH_OPTIONS]
Forward a remote MySQL port to your local machine:
**Using plain SSH:**
ssh -L 5000:localhost:3306 alexander@remoteserver.org
**Using autossh:**
autossh -L 5000:localhost:3306 alexander@remoteserver.org
autossh -M 0 -o "ServerAliveInterval 30" -o "ServerAliveCountMax 3" -L 5000:localhost:3306 alexander@remoteserver.org
#### Option explanations:
- `ServerAliveInterval`: Seconds between sending keepalive packets to the server (default: 0). - `ServerAliveCountMax`: Number of unanswered keepalive packets before SSH disconnects (default: 3).
You can also configure these options in your `~/.ssh/config` file to simplify command-line usage.
