ngrok: Expose TCP traffic on a given port.
$ ngrok tcp ${22}
try on your machine
This command is using ngrok, a tunneling software, with the "tcp" directive to create a secure tunnel over TCP protocol. The "${22}" is a variable that represents the standard Secure Shell (SSH) port number, which is typically 22.
By running this command, ngrok will create a tunnel that forwards incoming connections to the local machine's SSH port (22) through a randomly generated public URL or IP address. This allows remote clients to establish a secure SSH connection to the local machine without directly exposing it to the internet.
Overall, this command enables secure remote access to the SSH service running on the local machine using ngrok's tunneling capabilities.
