Ngrok exposes local servers behind NATs and firewalls to the public internet over secure tunnels. I've put together a simple service to make sure you always have a SSH tunnel open.
NOTE. This has only been tested on Kali Linux 2021.
The service file has been setup to open connections to SSH, but by editing the ngrok.service file, you can expose any other port. You can also open multiple tunnels. Please see https://dashboard.ngrok.com/get-started/tutorials for more details.
NOTE. If you make changes to ngrok.service after installation, be sure to run systemctl daemon-reload to affect the changes.
The script has been setup to download the files to /opt/ngrok and open a SSH tunnel.
