        I know someone that is running a public Game server. He's actually
facing a DDOS SYN flood by a player that has been banned from the server
because of rules violation.

I would like to know if you guys can point me to a good paper on how to
mitigate the effect of the attack in order to be able to keep the system up.
I don't have physical access to the server and I tried to help him out the
best as I could but it would be easier to send him a good paper on the

BTW the server is in co-location on a 100mbits link and is running 2k
server. I helped him to harden the server a little bit since it was WIDE

It helped somewhat but the server is still unable to deal with the flood.

If you want more info ill be glad to give it out.

Thx for your inputs
