Hi There,
 
I am writing an service that should be reply some information via TCP.
After starting the service a second PC try to connect with the service.
 
In the OnStart of the service I create an instance of my comunication class with:
 
string urlService = "net.tcp://192.168.10.48:1234/MyService";
 
host = new ServiceHost(typeof(ServicePCBI));
host.Opening += new EventHandler(host_Opening);
host.Opened += new EventHandler(host_Opened);
host.Closing += new EventHandler(host_Closing);
host.Closed += new EventHandler(host_Closed);
 
NetTcpBinding tcpBinding = new NetTcpBinding(SecurityMode.None);
 
host.AddServiceEndpoint(typeof(IServiceTest), tcpBinding, urlService);
 
host.Open();
 
 
This part of code runs and listen to the port, I write an logfile to check all events and it looks like everything is ok.
I have checked the IP of the service (first I had an wrong IP, but was no big change to correct this).
 
Here one of the tests, that not work
Socket sock = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.IP);
IPAddress addr = IPAddress.Parse("192.168.10.48");
IPEndPoint endpoint = new IPEndPoint(addr, 1234);
AddToLogFile("start listen! ");
while (true)
{
     sock.Bind(endpoint);
     sock.Listen(10);
     Socket client = sock.Accept();
     AddToLogFile("Now ok! " + client.LocalEndPoint.ToString());
}
 
Has anyone an idea why I can't connect with the socket in the service?
Thanks
