My server is getting TSource Query Floods. Rate limiting doesnt helps as that makes server appear offline but just allows to stop lag to those who playing however ddos ends hours so on map change server gets empty. I find query cache an option.
Here is a script for query caching which as per me could help us but the script is old and so no more functional. Does anyone have enough knowledge and could please spare some of his time to fix it?
Please if possible also make it like during too many incoming packets (suspected ddos) do query cache interval to 5secs while in normal 1secs maybe?
I read OVH site. For TSource Query Floods they also use query caching but with their own high quality hardware which could handle too much. My server could atleast be able to handle basic such floods.
NOTE : Each packet is from.different IP (spoofed)
