MySQL remote access on local network giving authentication error

I can access my MySQL server on my remote Ubuntu 10.04 machine downstairs (local network) just fine through SSH, and when I sudo in to MySQL monitor using the MySQL password, I can modify any of the tables.

However, I am on my Windows 7 box upstairs, and when I try to use a conventional SQL GUI application, I consistently get a:

1045 - Access denied for user 'root'@'COMPUTERNAME' (using password: YES)

I've also tried to use an SSH tunnel and then access the serve开发者_开发百科r, but no dice. Same authentication error. I've double, triple checked my password and still nothing.

Also, the bind address in my.cnf is set to 0.0.0.0 (and previously I had it commented out). Any help is greatly appreciated.

Take a look at the users table in the MySQL database. The "root" user is probably only allowed access from localhost. You can add more hosts if you like or add % to allow every host to connect to your database.

MySQL basically contains a simple firewall inside the database. This is annoying from time-to-time since firewalling should be the concern of the operating system or some piece of hardware, but not the database (just my two cents).
