There is an HTTP service listening on port 127.0.0.1:5000. Your task is to make this service also available on 0.0.0.0:6000. You're not allowed to change the service configuration or restart it.

Port forwarding with a user-space proxy (socat, netcat, etc.)

Hint 1 💡

socat is a universal "relay" tool that can forward data between two arbitrary endpoints (files, pipes, sockets, etc.).

Hint 2 💡

In the socket-forwarding mode, socat acts as a proxy server that accepts connections on one end and forwards data to a predefined destination on the other end.

Hint 3 💡

Knowing the main steps a typical socket server performs to accept and process a connection will help you grasp the socat port forwarding command syntax.
