NTOP & mysqladmin

Hi. On my 9.1 system I'm trying to set up NTOP. If I run mysqladmin, I get this: mysqladmin create NTOP mysqladmin: connect to server at 'localhost' failed error: 'Access denied for user: 'root@localhost' (Using password: NO)' Is it a permission problem, and if, how can I tackle it, and where ? -- venlig hilsen - best regards Erik Jakobsen
