That is, beginner can access this MySQL server from anywhere via a password (assuming my MySQL server is mysql.test.com) but when I run

On the tip:

ERROR 2013:lost connection to MySQL server during query

Actually, I just need to type

Mysql-h mysql.test.com appears above the hint, that is, it has not yet to verify the password that step. <br>

This problem is caused by a bug in glibc.

In some versions of glibc, the GETHOSTBYADDR function (exactly _nss_dns_gethostbyaddr_r) has a buffer overflow problem that can cause segment FAULT when processing large data.

When processing a remote connection, MYSQLD calls the Ip_to_hostname () function, which then calls the GETHOSTBYADDR function, and the system crashes at the execution Nss_dns_gethostbyaddr_r function. Therefore, the above situation will occur.

The way to solve the problem is to upgrade glibc.
