服务器上需要安装WSH2.0或者更高版本
如果您的系统目前没有安装WSH2.0,您可以从以下这个地址去下载它
http://www.microsoft.com/msdownload/vbscript/scripting.asp
里面包含了WSH2.0
下面是源代码
<%@ Language="VBScript" %>
<% Option Explicit %>
<%
If Request.Form("frmHost") = "" Then
'设置初始值
strIP = Request.ServerVariables("REMOTE_ADDR")
Else
strIP = Request.Form("frmHost")
End If
%>
<%
rMethod = uCase(Request.ServerVariables("REQUEST_METHOD"))
If rMethod = "POST" Then
' Lookup Host
strReturn = nsLookup(strIP)
If strReturn <> "" Then
Response.Write strReturn
Else
' A Lame Host is any Valid Host that DNS Cannot Resolve
' See InterNic for Details
Response.Write "Lame Host - Could Not Resolve DNS For " _
& strIP & "
"
End If
End If
Function NSlookup(strHost)
'Create Shell Object
Set oShell = Server.CreateObject("Wscript.Shell")
'Run NSLookup via Command Prompt
'Dump Results into a temp text file
oShell.Run "%ComSpec% /c nslookup " & strHost _
& "> C:" & strHost & ".txt", 0, True
'Open the temp Text File and Read out the Data
Set oFS = Server.CreateObject("Scripting.FileSystemObject")
Set oTF = oFS.OpenTextFile("C:" & strHost & ".txt")
tempData = Null
Data = Null
i = 0
Do While Not oTF.AtEndOfStream
Data = Trim(oTF.Readline)
If i > 2 Then ' Don't want to display local DNS Info.
tempData = tempData & Data & "
"
End If
i = (i + 1)
Loop
'Close it
oTF.Close
'Delete It
oFS.DeleteFile "C:" & strHost & ".txt"
Set oFS = Nothing
nsLookup = tempData
End Function
%>
代码很简单,我不多说了,如果您对WSH有什么疑问的话,请去下载WSH的电子文档中文版本的,CHINAASP下载区就有的吧
希望能对你有所帮助。
