Hello,
Many server admins are reporting to have their servers attacked. There
are several methods used to attack a srcds servers:
-UDP Flood: A packet specially crafted could make pings raise in the
server. Search SRCDS DoS Fix in google, I don't remember the exact names
now, but I currently use one from sourceop.com
-A2S Queries flood: an A2S Query UDP packet with random source ip is
flooded making the server freeze for not being able to handle that
large amount of queries. This attack must be done with a high bandwidth
connection (not sure). This can be partially fixed using 'A2S Query
Cache' or IPTables
I suggest you to look to the simmilar threads in this mailing list

Afternoon (at least for me it is at the moment) all,
We've had some issues on CSS servers the last 2 days with what appears
to be targeted attacks (ie. DDoS) on our servers. Approximately the
same time, for a few minutes and the attack is based on the IP.
Just wondering if anyone's aware of anything that may be causing this
from the game server side? or if we're actually being attacked...
I suspect/believe the latter.
