昨天因为出差在郊区开会没有上网,回家后看CPU负载图,壮观~~~ 这是大海么?我想吐….

IP:220.181.61.224一天就有1200多次日志内容

从日志来看,首先是没有主机头,也就是用IP地址直接发起的URL请求,IIS不能分辨属于哪个主机,所以有”400 -Hostname“的标识。
该IP的地址最后追踪到重庆师范大学图书馆

于是我编辑了 C:Windowssystem32inetsrvMetaBase.xml 文件,搜索" MinFileBytesPerSec ", MinFileBytesPerSec 设置从 240 更改为 0。 " ConnectionTimeout "减少为30,保存后重新启动IIS。
再一回想重庆师范大学图书馆那个IP实在恶心,这几天光它的日志就有28,562行,占到日志总量4.5 % 。
还发那么多垃圾请求,要么是傀儡机要么是恶意攻击,直接把IP屏蔽!!!
在C:WINDOWSsystem32LogFilesHTTPERR目录下检查日志,发现大量Timer_MinBytesPerSecond异常
