Here is my suggestion to you friend: Your server has too many services running there. You can either add a firewall or disable no useful services ... -bugfree(BugFree) @佛州华人论坛:佛州枫下论坛 The Rolia Forum of Florida

工作学习 / 专业技术讨论 / 请教高手, 如何对付网络攻击. -randomwalk(*%_%*); 2005-10-29 {175} (#2578948@0)
我一朋友的游戏网站最近老受攻击, 在2-3分钟里，他们的上传和下载都是将近4Mbs，网络很堵，游戏中的人很大一部分都被挤掉线了. 怎么知道是谁, 用什么方法攻击的, 应该如何对付?

多谢！

用一些软件象netstat察看谁访问机器，如果能确定攻击者，用防火墙拒绝它的访问。 -holdon(again); 2005-10-29 (#2579138@0)
"网络攻击"? what kind of? DDOS or normal. Firewall can help you in some way. I can give you more solution when you give more information. -bugfree(BugFree); 2005-10-29 (#2580034@0)

具体我也搞不懂,但是有netstat output. -randomwalk(*%_%*); 2005-10-29 {34208} (#2580133@0)
本文发表在 rolia.net 枫下论坛This is what I got from the netstat. The 2nd netstat output shows that there were a lot of time_wait. After that, most of the connections were lost.

Could you please take a look? If you need more information, please let me know. Thanks a lot!

Here is my suggestion to you friend: Your server has too many services running there. You can either add a firewall or disable no useful services ... -bugfree(BugFree); 2005-10-30 {1046} (#2580605@0)
本文发表在 rolia.net 枫下论坛I assume the main two ports your game server depending on are 7220 and 7210. You use windows Remote desktop to manage your server (port 3389). I do not know what service running on port 7000. And all rest services you can close if you do not needed. I did not cover the UDP services.
