            Returns:
                dict

            >>> s = _syncthing().system
            >>> connections = s.connections()
            >>> sorted([k for k in connections.keys()])
            ['connections', 'total']
            >>> isinstance(connections['connections'], dict)
            True
            >>> isinstance(connections['total'], dict)
            True
