        public TcpServer​(java.net.InetAddress bind_addr,
                         int port)
                  throws java.lang.Exception
        Creates an instance of TcpServer that creates a server socket and listens for connections. The end port defaults to (port + 50). Needs to be started next.
        Parameters:
        bind_addr - The local address to bind to. If null, the address will be picked by the OS
        port - The local port to bind to. If 0, the port will be picked by the OS.
        Throws:
        java.lang.Exception - Thrown if the creation failed

                  throws java.lang.Exception
        Creates an instance of TcpServer that creates a server socket and listens for connections Needs to be started next.
        Parameters:
        thread_factory - The thread factory used to create new threads
        socket_factory - The socket factory used to create sockets
        bind_addr - The local address to bind to. If null, the address will be picked by the OS
        srv_port - The local port to bind to. If 0, the port will be picked by the OS.
        end_port - If srv_port is taken, the next port is tried, until end_port has been reached, in which case an exception will be thrown. If srv_port == end_port, only 1 port will be tried.
        external_addr - The external address in case of NAT. Ignored if null.
        external_port - The external port on the NA. If 0, srv_port is used.
        recv_buf_size - The size of the initial TCP receive window (in bytes)
        service_name - The name of the service
        Throws:
        java.lang.Exception - Thrown if the creation failed
