关于用ASP.Net识别远程主机服务器种类

这几天做ASP.Net追捕，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

因为是摘出来的，所以有的变量没有定义，大家自己去琢磨吧。
