URGENT: What does: unauthenticated user mean & how to BLOCK them?
Today doing "Show processlist" we see the following entry in the results:
User: unauthenticated user: 220.127.116.11:46587
along with the other entries showing root running various queries.
FYI: above IP is from China and we have been getting all sort of problem with IPs from China.
1- How do we Stop this unauthenticated user accessing our MySQL server?
2- Is this a real access to our MySQL server or something else?
Thank you for your thoughts & suggestions on this matter.
