Server setup - help request

filda123xx · 10/05/2025, 10:19

Hello everyone, I have decided to dive into server development learning so that I can contribute to future project and help the community. The main goal is setting up a server a successfully logging-in.

I have decided to use the Sources (Old-School), which I believe are 3.5 sources. This time with VS 2003 and SQL Express 2022. I compiled both Server and Client without any major issues, ending with 0 errors and 0 warnings. Both solutions linked to the same TProtocol.

For TServer I compiled TNetLib, TControl, TLogin, TMap, TWorld, TRelay and TPatch.

For TClient I compiled TProtocol, Engine Lib, TachyonControl, TachyonShader, TClient.

Now I realize I Rebuilt TServer linking to TProtocol which I later rebuild inside the TClient - could that be a problem?

Every service is up and running except for the TRelay, which starts and shuts down immidiatelly, but I suppose you do not need it for test login, right?

I then replaced the TClient inside the Classic4story data folder with the newly compiled TClient, but upon log-in I still get the same network connection error (A network error has caused the server connection to fail).

I checked all I could but I cannot get pass the log-in screen. Any advices? If there is any experienced dev willing to help via discord, please feel free to add me: #filas2968.

U need edit TLoginSvr->TLoginSvr.cpp
