misdocumeno, i think you don't read previous posts. Please re-read them.

You should not use it cause it's method deprecated: https://forums.alliedmods.net/showpo...7&postcount=47

I'm still rewriting codebase.

And answers to your questions is:

Q: how it works? it detects possible DoS attacks and redirects them to a proxy before they can reach the srcds, so it doesnt get overloaded?
A: No any auto-detection. Redirect and respond from cache for predefined packets types. It's can be used for A2S Flood Attack (when server spammed by info queries).
Now redirected only: A2S_INFO/A2S_PLAYERS/A2S_RULES: https://developer.valvesoftware.com/wiki/Server_queries

Q: SourceQueryCacheMono? I'm stuck ( i dont know what else to do, i dont know how to test it, i dont know if installing it with DKMS builds poc.ko too, if so, i dont know where is it, i dont know if it has to be loaded manually, basically im stuck)
A: Wait for new release. It will be fully automated. In the end you will be needed install 2 packets to your system and run. Other things will be configured automatically.
