Testing Master Servers Yourself - A Useful Guide

[Fullserver]

I cannot understand this, is this to track from what boost service players joined or anticheat plugin? inside is ban plugin for opengl(wh) im so confused

Yes, you use the plugin that was designed for anticheat purposes because the way it works it recognizes the HASH of files, therefore it was used to recognize the hash of cheat files. But as it recognizes a hash of any file at all it can be used in a way to recognize masterserver.vdf file which isn't a cheat file but a file that contains a master server.
