  这几天做捕,也算是我入门吧。思路很简单,主要就是识别远程主机传回的Banner,
判断远程主机服务器。这可能不够准确,因为合格的管理员可能会去修改Banner。

  代码如下(从我的Web追捕里找出来的,用VB.Net)

Dim swWriter As StreamWriter
用以向网络基础数据流传送数据
Dim nsStream As NetworkStream
创建发送数据的网络基础数据流
Dim tcpClient2 As TcpClient
通过它实现向远程主机提出TCP连接申请
Dim sHostName As String
Dim srRead As StreamReader
从网络基础数据流中读取数据
HTTP服务追捕
If TcpConnect(ZSIP, 80) = CG Then
OppHTTP.Text = HTTP服务已开启!服务软件类型:未知
Try
tcpClient = New TcpClient(IPAddress, Port)
tcpClient2 = New TcpClient(ZSIP.ToString(), 80)
tcpClient2.ReceiveTimeout = 1000000
tcpClient2.SendTimeout = 1000000
对远程主机的8000端口提出TCP连接申请
nsStream = tcpClient2.GetStream()
通过申请,并获取传送数据的网络基础数据流
swWriter = New StreamWriter(nsStream)
swWriter.WriteLine(Get /index.htm HTTP/1.1)
swWriter.WriteLine(Host: IP.Text)
swWriter.WriteLine(Accept:*/*)
swWriter.WriteLine(Referer:)
swWriter.WriteLine()
刷新当前数据流中的数据
swWriter.Flush()
srRead = New StreamReader(nsStream, Encoding.Default)
以得到的网络基础数据流来初始化StreamReader实例
Dim L As Integer = 0
Do While Not srRead.Peek = -1 And L < 20
StrHttp = StrHttp srRead.ReadLine()
L = L + 1
Loop
If InStr(StrHttp, IIS) > 0 Then
OppHTTP.Text = HTTP服务已开启!服务软件类型:IIS 版本未知
SystemFW = WindowsNT/2000/XP/2003
End If
If InStr(StrHttp, Apache) > 0 Then
OppHTTP.Text = HTTP服务已开启!服务软件类型:Apache 版本未知
End If
If InStr(StrHttp, Netscape-Enterprise) > 0 Then
OppHTTP.Text = HTTP服务已开启!服务软件类型:Netscape-Enterprise 版本未知
End If
If InStr(StrHttp, Microsoft-IIS/5.0) > 0 Then
OppHTTP.Text = HTTP服务已开启!服务软件类型:IIS 5.0
SystemFW = Windows2000
End If
If InStr(StrHttp, Microsoft-IIS/5.1) > 0 Then
OppHTTP.Text = HTTP服务已开启!服务软件类型:IIS 5.1
SystemFW = Windows2000/XP
&n
