用ASP.Net識別遠程主機服務器種類
這幾天做ASP.Net追捕，也算是我入門吧。思路很簡單，主要就是識別遠程主機傳回的Banner，判斷遠程主機服務器。這可能不夠準確，因為合格的管理員可能會去修改Banner。
代碼如下（從我的Web追捕裏找出來的，用VB.Net）
DimswWriterAsStreamWriter
'用以向網絡基礎數據流傳送數據
DimnsStreamAsNetworkStream
'創建發送數據的網絡基礎數據流
DimtcpClient2AsTcpClient
'通過它實現向遠程主機提出TCP連接申請
DimsHostNameAsString
DimsrReadAsStreamReader
'從網絡基礎數據流中讀取數據
'HTTP服務追捕
IfTcpConnect(ZSIP,80)="CG"Then
OppHTTP.Text="HTTP服務已開啟！服務軟件類型：未知"
Try
'tcpClient=NewTcpClient(IPAddress,Port)
tcpClient2=NewTcpClient(ZSIP.ToString(),80)
tcpClient2.ReceiveTimeout=1000000
tcpClient2.SendTimeout=1000000
'對遠程主機的8000端口提出TCP連接申請
nsStream=tcpClient2.GetStream()
'通過申請，並獲取傳送數據的網絡基礎數據流
swWriter=NewStreamWriter(nsStream)
swWriter.WriteLine("Get/index.htmHTTP/1.1")
swWriter.WriteLine("Host:"&IP.Text)
swWriter.WriteLine("Accept:*/*")
swWriter.WriteLine("Referer:")
swWriter.WriteLine()
'刷新當前數據流中的數據
swWriter.Flush()
srRead=NewStreamReader(nsStream,Encoding.Default)
'以得到的網絡基礎數據流來初始化StreamReader實例
DimLAsInteger=0
DoWhileNotsrRead.Peek=-1AndL<20
StrHttp=StrHttp&srRead.ReadLine()
L=L+1
