用抓包工具把电脑病毒揪出来
你是网络管理员吗?你是不是有过这样的阅历:在某一天的早上你突然发现网络功能急剧下降,网络服务不能正常提供,服务器访问速度极慢乃至不能访问,网络交换机端口指示灯张狂地闪耀、网络出口处的路由器现已处于满负荷的工作状况、路由器CPU现已到了百分之百的负荷……重启动后没有几分钟现象又从头出现了。这是啥问题?设备坏了吗?不可能几台设备同时出问题。一定是有啥大流量的数据文件,耗尽了网络设备的资源,它们是啥?如何看到它们?这时有经验的网管人员会想到用局域网抓包工具来分析一下。(Are you a network administrator? Have you ever had such an experience: in the morning of one day you suddenly found that the network function dropped sharply, the network service could not be provided normally, the server access speed was extremely slow or even inaccessible, the network switch port indicator flashed wildly, the network exit at the network exit The router is now at full load, the router CPU has reached 100% load... The phenomenon reappeared within a few minutes after restarting. What's the problem? Is the device broken? It is impossible for several devices to have problems at the same time. There must be some high-traffic data files that exhaust the resources of network devices. What are they? How to see them? At this time, experienced network administrators will think of using a local area network packet capture tool to analyze it.)
