当我运行mysqladmin proc
或查看 MySQL 服务器进程列表时,我经常看到一个用户标记为:尝试连接的未经身份验证的用户。
+-----+----------------------+--------------+-----------------+---------+------+------------------+------------------+-----------+---------------+-----------+
| Id | User | Host | db | Command | Time | State | Info | Rows_sent | Rows_examined | Rows_read |
+-----+----------------------+--------------+-----------------+---------+------+------------------+------------------+-----------+---------------+-----------+
| 40 | unauthenticated user | x.x.x.x:xxxx | | Connect | | Reading from net | | 0 | 0 | 0 |
什么可能导致这样的事情?
这是正常的,还是我应该调查我的系统是否存在任何漏洞或安全漏洞?
谢谢
