Hi brahs.

Im using Ubuntu 10.04 64bits.

My server are online normal. In random uptime I lost connection with my mysql.

Players are online and playing normal but if die or logout cannot come back.

My friend said for me to use the command to fix this:
PHP: 
 iptables -A INPUT -p tcp --syn -m limit --limit 10/s --limit-burst 15 -j RETURN

But it seems not work. Can anyone help me? The problem isnt my rev! Is the machine are doing it.

Why?!

bump

You need more protection against attacks.
This smells like it's some syn attack on your game port
The iptables do not work against big attacks

So my server is losing the connection because of the attacks? But I didn't receive attacks in the last two days and it happened.
