The mass connection thing is happening to me again right now. I tried to ban the IP too. I have done everything and can't seem to stop it. Have you gone to
www.utpg.org and read what they said? Are you running Patch 451? Your being attacked my friend. My log is full of this and I mean hundreds, thousands of lines of it:
Log: More than 5 logins per minute for 130.230.72.156. Ignoring.
I think that means I'm being attacked but the patch is working. Here is a quote from the UTPG folks:
DOS Exploit Fix UT General :: Jul-17-03
If you find your server being used for a DOS type attack, you need to upgrade to 451 (or find an old copy of 440). You can tell by looking in your server log and seeing a lot of conn open/close messages very close together (while the server is empty). To fix this, upgrade and do the following:
Ensure that under your [Engine.GameEngine] section it reads:
[Engine.GameEngine]
ServerActors=IpServer.UdpServerQuery
***Please note if you are using any other IPServer you will need to remove that line from your server's .ini file and replace lines like below with the line above:
UT Pure IP Server Update: ServerActors=PureIpServer.PureUdpServerQuery
BDB's IP Server Update: ServerActors=IpServer2.UdpServerQuery2
In addition, you need to verify the following lines are also in your server.ini file:
[IpDrv.TcpNetDriver]
MaxConnPerIPPerMinute=5
LogMaxConnPerIPPerMin=True
AllowPlayerPortUnreach=True
LogPortUnreach=False
You can change the max number of conn per min to be even lower then 5 if you so wish. By turning on/off logging this will enable you to reduce the impact on your log files as well.
That's what I got from UTPG. Let me know if you get better luck than I've had.
