How to connect two ports?

Question

linux

How to make two clients connect to different ports on the same server and interact with each other?

For example, one clung to 1111, the other 2222 and exchanged data, the format is not important, raw data.

I did not find a ready-made solution, maybe I was looking badly? I so understand it is necessary to lift sockets?

Answer 1

socat tcp-l:1111,fork,reuseaddr tcp-l:2222,fork,reuseaddr
