Quick Question

First off, let me say that I have not ever looked into getting/using a PServer, so sorry if I sound like a total noob. I have 2 questions that can be answered pretty easily.

First, is it possible to just host a PServer on my computer that only I can connect to? Or is it more complicated than that? I just want one that I can hack on without having to worry about GMs or other people, etc.

Second, would it be as hard to hack my PServer as it is to hack 2moons? Meaning, do I have to make a no_crc for my PServer, or is there a way to get around that?

Sorry for being a noob, and thanks for the help!

EDIT: Basically, what I want to do is just find a way to log in to a server without other people there.

First question is unknow to me since I never made one myself nor know the answer XD
But the 2nd one is depend on how you work with your security. Most pserver that are made fresh is mostly likely hackable if the owner dont know how to put a good security.
