yea, but when I compared it with the tutorial, this part is missing -->

+SERVICE [/rosout/get_loggers] /rosout http://aqy:53163/
+SERVICE [/rosout/set_logger_level] /rosout http://aqy:53163/
+SUB [/time] /rosout http://aqy:53163/
+PUB [/rosout_agg] /rosout http://aqy:53163/
+SUB [/rosout] /rosout http://aqy:53163/

and then when I close the terminal and open it again and use any of the
rosnode commands it gives me (unable to communicate with master!)
