How to start writing a game server?

Question

Game development

Good afternoon, tell me, I tried to find topics on the Internet about writing the server itself, but everywhere there are only links to ready-made ones.
Where to start, what to read about creating a server for an existing game?
How do they write servers for Mu and Lineage from scratch, where did they start in order to understand how to write them?
Where can I see sample code?

Answer 1

Writing such a server is a rather complicated procedure, and if there was no experience in development, then it is unlikely that something workable will turn out from the start. I can advise you to look at this book, it also contains code examples. https://vk.com/wall-54530371_90186
