A step in the right direction

How can I prevent dos attacks on my server? We limited ipcomplainlimit to 3 but are there other ways to prevent it?

What kind of attacks do you mean?

 

How did you recognize your server is under attack?

If you have higher level access you can use IP tables to block IP addresses that send/request too much information. Also there are some common client requests that some malicious players use to attack a server (not going to list them for obvious reasons).

 

Talk with your server provider if you have one, and if they value you as a customer they should be willing to block the offending IP addresses. if you are running your own non-supported server then google ddos and IP tables and prepare to do some studying.

 

Good luck we have all been ddossed and it is no fun.

Someone tried to fill the server with clients from the same ip address. Ofc we limited that with ipcomplainlimit. That guy used probably that q3fill program.

That's very old exploit and silent mod deals with it effectively. That's not DoS attack.

DoS attacks are hard to mitigate and would end up costing hundreds if it's big attack. Normal procedure is to null route the IP if the attack is huge.
