Hello!
I have several dedicated servers that I host Counter-Strike 1.6 servers.
They receive attacks that spam query requests, the attack is called Valve Source engine query flood. As long as the attack is active, the server no longer appears in the browser and players who are not already connected to the server can no longer connect until the attack stops.
I understand that this attack can be stopped using "cache query responses" this way it would no longer communicate directly with the server and solve the problem.
So I need to integrate this method or if you know another.
The dedicated servers have Debian as their operating system.
If there is anyone who knows, I am waiting for offers.

This sounds like a DOS or DDOS attack (distributed denial of service). This is a well known method of attack and IIRC you can't prevent this at the server level. Search about DDOS.

Thanks!
So, what exactly about DOS or DDOS doesn't apply here?
