Same problem. My server is under attack with this ddos for now . We really need a fix

[Divin12]

Add in server.cfg sm_cvar qc_requestmap_enabled "0"
If you do not add this at the end of map your server will crash.
Copy qcache_mm.so in addons folder and qcache_mm.vdf in addons/metamod. Restart server and job done.

Thank you Divin12, I will test what you have sent and I will come back with an answer.

What exactly does that do and how does it affect my servers?

This is not working. I tried this.

It is extracted from my server, so you don't know how to follow 3 steps. Be carefoul, .so file need to be droped in addons folder not in extension folder.

Where the attack is DDoS (such as NTP response amplification), only your hosting company (may be able to) help. You need cleanpipe ddos mitigation which happens in the cloud before it even reaches your gameserver. A saturated link into your gameserver will make it unusable regardless of what plugins/lines of code you add.

Cleanpipe uses something called BGP Anycast to re-route traffic to a ddos scrubbing centre, however it will add ~100ms ping to every player but can usually stop most layer 1-3 volumetric attacks. Layer 7 (application based) attacks can be handled with less latency overhead.

Systems from Akamai, Radware, Tilera and others can block all of these attacks. However, unless you have big money to invest in such a solution and host it yourself, getting someone else to do this for you is a better idea.

OVH offer such protection, although what you get is based on which package you choose/pay for and you will need a dedicated server from them to benefit. Some other game hosting providers claim to offer DDoS protected servers, however I have never tested any of them so can't say if they work well or not. Perhaps someone else can share names of game server hosting companies that offer a tried and tested solution.

Good luck!

Dude, with this metamod extension I solved my problem. That's all what I know. It solved completly my problem. No more server restart after 2-3 rounds and console spam message. Problem completly solved, my server is like before attack. It appear in masterservers etc.

Unfortunately it does not working, Divin12 my hosting has no ddos protection and maybe this is the problem for which your solution does not work.

Type in console meta list and see if extension is working, leave a message here with extensions list.
