To achieve this with socat, you can set up a listener on a local TCP port that forwards incoming connections to another host and port using SSL. Additionally, you can enable forking so that each incoming connection is handled by a separate process.

Here's an example command:

socat -d -d -d TCP-LISTEN:LOCAL_PORT,fork,reuseaddr OPENSSL:REMOTE_HOST:REMOTE_PORT,verify=0

Explanation of the options used:

• -d -d -d: Enable debug output (optional but useful for troubleshooting).
• TCP-LISTEN:LOCAL_PORT: Listen on the specified local TCP port.
  • fork: Fork a new process for each incoming connection.
  • reuseaddr: Allow reuse of the address (useful if restarting socat quickly).
• OPENSSL:REMOTE_HOST:REMOTE_PORT: Forward the connection to the specified remote host and port using SSL.
  • verify=0: Disable SSL certificate verification (you may want to adjust this based on your security requirements).

Replace LOCAL_PORT with the local port number you want to listen on, and replace REMOTE_HOST and REMOTE_PORT with the target host and port you want to tunnel to via SSL.

Example usage:

socat -d -d -d TCP-LISTEN:8080,fork,reuseaddr OPENSSL:www.example.com:443,verify=0

This command will listen on local port 8080. When a client connects to this port, socat will fork a new process and forward the connection over SSL to www.example.com on port 443.
