Dear all,

When using the OnOff application in combination with ns3::TcpSocketFactory and IPv6, the TCP session cannot be established at all. Right after the socket was created it got closed again without listening to any packet. The reason for this is when working with IPv6, the wrong binding function (m_socket->Bind() instead of m_socket->Bind6()) is called when binding the application to a previously created socket.

/*
 * File: src/applications/model/onoff-application.cc
*/
void OnOffApplication::StartApplication () // Called at time specified by Start
{
  NS_LOG_FUNCTION (this);

  // Create the socket if not already
  if (!m_socket)
    {
      m_socket = Socket::CreateSocket (GetNode (), m_tid);

+      if (Inet6SocketAddress::IsMatchingType (m_peer))
+    	  m_socket->Bind6 ();
+      else if (InetSocketAddress::IsMatchingType (m_peer))
+    	  m_socket->Bind ();

-     m_socket->Bind ();

      m_socket->Connect (m_peer);
      m_socket->SetAllowBroadcast (true);
      m_socket->ShutdownRecv ();

      m_socket->SetConnectCallback (
        MakeCallback (&OnOffApplication::ConnectionSucceeded, this),
        MakeCallback (&OnOffApplication::ConnectionFailed, this));
    }
  // Insure no pending event
  CancelEvents ();
  // If we are not yet connected, there is nothing to do here
  // The ConnectionComplete upcall will start timers at that time
  //if (!m_connected) return;
  ScheduleStartEvent ();
}
