COD2 Linux Server - Latest Server Attacks / Flooding / Help

[own3mall]

I'm running a COD2 1.0 Linux server with Libcod (this version: https://github.com/damage99/libcod), but players report the server is under attack, randomly lags, and rcon can quit working while it's being flooded.

I found and am using these iptables rules: https://killtube.org/showthread.php?...tables+--flush

Unfortunately, it doesn't appear to be helping. What kind of server attacks are the hackers / exploiters using today in 2024? Are there any additional iptables rules I should set?

In the server.cfg, are there log settings that can help capture some of these attacks? The log is pretty much empty and not of much help in determining what could be going on.

Any help would be appreciated.

You don't need any extra rate limiting iptables rules in combination with libcod's builtin rate limiting.
I don't know which new features you are using from damage99's libcod branch.
But It isn't protected against SV_DirectConnect flooding.
