Listening socket
- by hoodoos
I got a strange problem, I never actually expirienced this before, here is the code of the server (client is firefox in this case), the way I create it:
_Socket = new Socket( AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp );
_Socket.Bind( new IPEndPoint( Settings.IP, Settings.Port ) );
_Socket.Listen( 1000 );
_Socket.Blocking = false;
the way i accept connection:
while( _IsWorking )
{
if( listener.Socket.Poll( -1, SelectMode.SelectRead ) )
{
Socket clientSocket = listener.Socket.Accept();
clientSocket.Blocking = false;
clientSocket.SetSocketOption( SocketOptionLevel.Tcp, SocketOptionName.NoDelay, true );
}
}
So I'm expecting it hang on listener.Socket.Poll till new connection comes, but after first one comes it hangs on poll forever. I tried to poll it constantly with smaller delay, let's say 10 microseconds, then it never goes in SelectMode.SelectRead. I guess it maybe somehow related on client's socket reuse? Maybe I don't shutdown client socket propertly and client(firefox) decides to use an old socket?
I disconnect client socket this way:
Context.Socket.Shutdown( SocketShutdown.Both ); // context is just a wrapper around socket
Context.Socket.Close();
What may cause that problem?
