I don't know if I need the flush-hosts command or what. The howto I use starts off with: mysqladmin -u root password 'mypass' mysqladmin -u root -h foo.bar.com password 'myhostpass' So I am changing foo.bar.com to bar.foo.com. So when I try: mysqladmin -u root -h bar.foo.com password 'myhostpass' I get mysqladmin: connect to server at 'bar.foo.com' failed error: 'Host 'bar.foo.com' is not allowed to connect to this MySQL server'
