Hello, I'm working on a school project where the goal is to create a computer reservation system. The idea is to have a client program on all the computers and have a server program on a dedicated computer. I have the client program finished, however, i'm having issues with the networking aspect. I want to make a database system where the client queries the server with the ID of the computer and time requested. I decided that using TCP sockets would likely be the best route due to lack of PostgreSQL or mySQL integration (SQlite isnt a client-server DBMS afaik). The issue is that I'm a noob at this and dont really understand exactly how TCP sockets work. Looking at some code that has been posted here before, i found this code made by [Login to see the link] . [Login to see the link] . However when I try executing it, it seems like server:bind() returns a false bool and thus outputs "Network error : cannot create the server Socket" on the output. did something change in a newer LuaRT version? I would appreciate any help!
