How to unblock with mysqladmin flush hosts

kar picture kar · Mar 9, 2014 · Viewed 287.4k times · Source

I have gone through similar cases listed here but it doesn't seem to work.

I was using MySQL Workbench to establish a connection with my database which is hosted on another server. Tried a few times and unable to connect followed by this error. I am confused as to where I should even do this flush. On PhpMyadmin under the SQL query? Cos when I tried to input the following command, it returns as syntax error. I am using a windows OS thus no shell shell scripting for me to input this information either. I am accessing the database temporarily via Cpanel/ phpmyadmin now.

Please help to tell where I should input this data and if my syntax is wrong. Thanks for help.

mysqladmin flush-hosts;

or

mysqladmin -umyname -pmypassword flush-hosts;

My error message as follows:

Failed to connect to MYSql at 192...* with user myName

Host 'host-92...*.as13285.net' is blocked because of many connection errors; unblock with 'mysqladmin flush-hosts'

mysqladmin is not a SQL statement. It's a little helper utility program you'll find on your MySQL server... and "flush-hosts" is one of the things it can do. ("status" and "shutdown" are a couple of other things that come to mind).

You type that command from a shell prompt.

Alternately, from your query browser (such as phpMyAdmin), the SQL statement you're looking for is simply this:

FLUSH HOSTS;
