Well at first thanks for trying to help me
Since this is my first time asking for help on the internet I need to learn how to specify my questions when asking.
I have written a program that compiles under Linux. For now though only on my computer, and it is not possible to connect to that program whatsoever.
My plan is to modify this software in a way so that it runs as a server on a certain IP in my local network (via PI). I don't have any idea on setting a server (or a similar stucture) up and this is what I am asking here. The program is written in C++.
Hope this outlines my problem, thanks in advance
