[Sugar-devel] Web activities on XO-4

[Gonzalo Odiard]

A free port can be get using:

            # Get a free socket
            sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM, 0)
            sock.bind(('', 0))
            sock.listen(socket.SOMAXCONN)
            _ipaddr, self.port = sock.getsockname()
            sock.shutdown(socket.SHUT_RDWR)
            logging.error('Using port %d', self.port)

Should be good use 0.0.0.0 as ip instead of localhost, to avoid [1]
To serve the files python already have HTTPServer.
