gentoo连接到外部mysql

Question

怎么能帮我连接外部mysql？

系统： cat / etc / gentoo-release Gentoo Base System版本2.3

mysql -h vpsxxx.ovh.net --port=12000 -u userxxx -p
Enter password:
ERROR 1042 (HY000): Can't get hostname for your address

mysql -h 149.xxx.xx.xx --port=12000 -u userxxx -p
Enter password:
ERROR 1042 (HY000): Can't get hostname for your address

从另一个带有Windows和Debian的系统工作这个地址perfekt。
