multi-tunnel

multi-tunnel allows starting and managing SSH tunnels in a straightforward manner. Create a TOML configuration file, start the service and you're all set. If you change the configuration, send a SIGHUP (aka systemctl reload) and it'll start/stop tunnels as necessary.

Tunnels that get stopped or killed for any reason will be restarted after a 5-second delay.

Configuration

For example, to tunnel httpd running on port 8080 to a remote server on 8000 and nginx running on port 8081 to 8001 on the remote server:

connection = "remote.host"

[httpd]
local = 8080
remote = 8000

[nginx]
local = 8081
remote = 8001

The name is arbitrary and is used only for log entries.

Monitoring

A Prometheus endpoint to scrape is available at http://0.0.0.0:46581/metrics.
