If are create more than eleven bad connection (ex. Bad Handshake)

This is the error:

mysql> connect test 127.0.0.1
ERROR 1129: Host 'localhost.localdomain' is blocked because of many
connection errors.  Unblock with 'mysqladmin flush-hosts'

Sorry but this is not a DoS against mysqld, 
this is a DoS against yourself!

Only connections coming from the offending IP address are blocked,
and I can't see anything wrong in this.
