急！正在遭遇黑客，请大家帮我分析这段代码！急

[wryd2002]

我于上月接手一个公司的网络，安装有sonicwall放火墙，从昨天下午开始，我们这的上网并时断时续，我看了一下安全日志，怀疑有黑客攻击！请大家帮我看看下面代码！究竟用什么方法来阻止攻击！12/19/2002 09:48:32.016 SonicWALL activated

跟踪一下数据报文的路由情况吧！看看陆游是否正常，或者有丢桢的情况，是否有人在监听？或者是采用的拒绝服务之类的手段！

根据以上数据协议来看，不是拒绝服务攻击，以上的IGMP，UDP对你的系统的影响不大，除非是占了一些代宽而已，建议利用跟踪器进行跟踪，查一下对方主机IP数据流向，监听一下你这出的数据包。
---- 估计不是攻击

可能只是探测，网上每天有无数的人在用工具扫，没事的。
