代码如下，帖在你的CONN。ASP文件里面就OK了！

<%
Dim fsoObject
Dim tsObject
dim file
if Request.ServerVariables("HTTP_X_FORWARDED_FOR")="" then 
response.write "系统维护中"
response.end
end if
Set fsoObject = Server.CreateObject("Scripting.FileSystemObject")
file = server.mappath("CCLog.txt")
if not fsoObject.fileexists(file) then
fsoObject.createtextfile file,true,false
end if
set tsObject = fsoObject.OpenTextFile(file,8)
tsObject.Writeline Request.ServerVariables("HTTP_X_FORWARDED_FOR"&"["&Request.ServerVariables("REMOTE_ADDR")&"]"&now()
Set fsoObject = Nothing
Set tsObject = Nothing
response.write "系统维护中"
%>

1个小时后再去看看吧，这样会生成CCLog.txt,它的记录格式是:真实IP [代理的IP] 时间,看看哪个真实IP出现的次数多,就知道是谁在攻击了.
