Sprache: C#
Eine einfache und effiziente Methode einen Port zu scannen. Standardmäßig ist das Protokoll auf TCP und der Timeout auf 5000ms gesetzt.
Aufruf:
[code]//Scan port 22@127.0.0.1
String ipAddress = "127.0.0.1";
int port = 22;
IPAddress ip=IPAddress.Parse(ipAddress);
IPEndPoint ipEo = new IPEndPoint(ip,port);
if (ScanPort(ipEo))
{
//Port 22 is open!
}[/code]
bool ScanPort(IPEndPoint ipEo, ProtocolType protocol = ProtocolType.Tcp, int timeOut = 5000)
{
Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, protocol);
IAsyncResult result = socket.BeginConnect(ipEo, null, null);
return result.AsyncWaitHandle.WaitOne(timeOut, true);
}bool ScanPort(IPEndPoint ipEo, ProtocolType protocol = ProtocolType.Tcp, int timeOut = 5000)
{
Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, protocol);
IAsyncResult result = socket.BeginConnect(ipEo, null, null);
return result.AsyncWaitHandle.WaitOne(timeOut, true);
