问题
When I try to connect with putty I get 'host is not allowed to connect to this mysql server'. Why is that happening? Host and client are on my machine.
When I connect with the command line it connects.

You need to change how your configuration is set up.
Comment out the skip-networking section within your MySQL config: # skip-networking, if you have skip-networking it will discard any TCP/IP connection which is likely why your failing.
Once you have enabled your TCP/IP connections you will need to grant permission to your user to connect from other machines:
GRANT ALL PRIVILEGES ON *.* TO <username>@'%' IDENTIFIED BY '<password>';
This will let username connect from any machine to your database with the appropriate password.
