I've seen many articles on DDoS protection, but none work. I need protection for a socket server i'm running on the server. It's running on port 9876 and it's for a flash-based game. when it gets attacked, the whole dedicated server goes offline for a few minutes. I have CSF firewall installed, and I tried configuring the portflood settings, but nothing helped.

my question is: how can I stop or slow down attacks on port 9876, it is NOT a webserver. it is a socket server written in PHP. I also have another one running on 9875 that is in python, but either way, how can I stop or slow down attacks??

I believe you're misusing the term "DDoS". If this was happening, there's nothing you can do about it other notifying your upstream provider.

If the game's being overwhelmed by requests, you can try to rate-limit the requests to something the server can handle. See this for details: http://www.debian-administration.org/articles/187

If that doesn't help, then there may simply be too much traffic.
