tcpserver

I'm writing a chat server and encountered the following problem while unit testing it. In one of my unit tests, I connect many test clients to my server. As the number of connected users get to 511 the server stops responding without any error message. At this stage everything runs locally on a PC. I have prepared a simple server, test client and unit test code to paste into the forum. Any idea why the server hangs up? Any help is much appreciated This code is basicly from the twisted simple chat tutorial. Simple server: from twisted.internet.protocol import Factory from twisted.protocols

I have used a Asynchronous TCP/IP server, everything works fine but when a client disconnects due to error or forced exit of the application it also closes my server due to an exception of type IO.IOException. The exception occurs in the following sub: Private Sub ReadCallback(ByVal result As IAsyncResult) Try Dim client As Client = TryCast(result.AsyncState, Client) If client Is Nothing Then Return End If 'MsgBox(client.ClientID) Dim networkStream As NetworkStream = client.NetworkStream Dim read As Integer = networkStream.EndRead(result) **' ERRORS HERE!** If read = 0 Then Dim client As

I would like to ask you, how it is possible to handle multiple connection threads. I have implemented TCP server in the following way: $endpoint = New-Object System.Net.IPEndPoint ([System.Net.IPAddress]::Any, 8989) $listener = New-Object System.Net.Sockets.TcpListener $endpoint $listener.Start() do { $client = $listener.AcceptTcpClient() # will block here until connection $stream = $client.GetStream(); $reader = New-Object System.IO.StreamReader $stream do { $line = $reader.ReadLine() Write-Host $line -fore cyan } while ($line -and $line -ne ([char]4)) $reader.Dispose() $stream.Dispose()

I am writing a simple SocketServer.TCPServer request handler ( StreamRequestHandler ) that will capture the request, along with the headers and the message body. This is for faking out an HTTP server that we can use for testing. I have no trouble grabbing the request line or the headers. If I try to grab more from the rfile than exists, the code blocks. How can I grab all of the request body without knowing its size? In other words, I don't have a Content-Size header. Here's a snippet of what I have now: def _read_request_line(self): server.request_line = self.rfile.readline().rstrip('\r\n')
