MYSQL remote read only access, how do I set it up?

I've seen stuff on how to enable remote access, but never how to restrict it so that users cannot make any changes. I tried doing this:

mysql> create user 'dude'@'boingoboingo.local' IDENTIFIED BY '007'; Query OK, 0 rows affected (0.00 sec)

This user cannot access any databases remotely. What do I need to grant for read only.

Solution 1:

mysql>grant select on *.* to 'dude'@'boingoboingo.local';

or only one database

mysql>grant select on DATABASE_NAME.* to 'dude'@'boingoboingo.local';
