remote-access

I am running a Ruby on Rails application on Heroku and my database is in someother place where it will be accessed with certain whitelisted IP's only but since heroku doesn't provide dynamic IP's I thought of using proximo.

The script will be started at boot and run continuously, monitoring a temperature, and cycling a heater on/off (via GPIO pins) to maintain the temperature stored in a "set_point"

I have an Ubuntu server with MySQL and many Stored Procedures (server A) and another Ubuntu server with MySQL (server B). I'd like to populate the database on server B with data from the stored procedures on server A. At this point I'd like to test the connection with no success. I tried this on server B: mysql> EXEC server_A_IP.DB_name.username.sp_courses(); But it gives this error: ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'EXEC server_ip.db_name.owner.sp_courses()' at line 1 This
