[转载]关于最近校园网发生的经常性断网情况,桃园BBS的说明

  近期国内很多单位和学校的局域网爆发一种新的"ARP欺骗"木马病毒(Address Resolution Protocol 地址解析协议),病毒发作时其症状表现为计算机网络连接正常,能登陆成功却无法打开网页;或由于ARP欺骗的木马程序(病毒)发作时发出大量的数据包,导致网络运行不稳定,频繁断网、 IE 浏览器频繁出错以及一些常用软件出现故障等问题。
一、故障现象及原因分析
情况一、当局域网内某台主机感染了ARP病毒时,会向本局域网内(指某一网段,比如:59.74.0.0这一段)所有主机发送ARP欺骗攻击,让原本流向网络中心的流量改道流向病毒主机,并通过病毒主机代理上网。因客户端具有防代理功能,造成受害者无法通过病毒主机上网。由于病毒发作时发出大量数据包会将网络拥塞,大家会感觉上网速度越来越慢。中毒者同样如此,受其自身处理能力的限制,感觉运行速度很慢时,可能会采取重新启动或其他措施。此时病毒短时间停止工作,大家会感到网络恢复正常。如此反复,就造成网络时断时续。
情况二、局域网内有某些用户使用了ARP欺骗程序(如:网络执法官、网络剪刀手、传奇木马、QQ盗号软件等)发送ARP欺骗数据包,致使被攻击的电脑出现突然不能上网,过一段时间又能上网,反复掉线的现象。
二、故障诊断
  如果用户发现以上疑似情况,可以通过如下操作进行诊断:点击"开始"按钮->选择"运行"->输入"arp -d"->点击"确定"按钮,然后重新尝试上网,如果能恢复正常,则说明此次掉线可能是受ARP欺骗所致。
  注:"arp -d"命令用于清除并重建本机arp表。"arp -d"命令并不能抵御ARP欺骗,执行后仍有可能再次遭受ARP攻击。
三、故障处理
  1、中毒者:ARP病毒专杀工具下载 1.96MB (务必下载安装后查杀);
  2、受害者:下载Anti ARP Sniffer软件 1.84MB 保护本地计算机正常运行   输入网关地址(点击"开始","运行",在窗口中输入"cmd",点"确定",调出"命令提示符"。输入并执行以下命令:ipconfig /all,"Default Gateway"后面对应的值就是用户所在子网的网关地址!)点击"枚取MAC地址",点击"自动保护"保证当前网卡与网关的通信不被第三方监听,最后选中"开机自动运行软件" 即完成了软件设置工作!
  3、如运行AntiArp程序仍无效果,可下载系统补丁以作尝试:
WINXP系统ARP病毒补丁 2KB  WIN2000系统ARP病毒补丁 30.8MB
