RH9自带的MySQL远程连接不上？

big-foolcat

我在本机上执行下边的命令可以连上MySQL：
[root@localhost root]# mysql -h localhost -u root -p

但执行下边的2个命令却连不上：(本机IP192.168.0.250)
[root@localhost root]# mysql -h 127.0.0.1 -u root -p
Enter password:
ERROR 1130: Host 'localhost.localdomin' is not allowed to connect to this MySQL server

[root@localhost root]#mysql -h 192.168.0.250 -u root -p
Enter password:
ERROR 1130: Host '192.168.0.250' is not allowed to connect to this MySQL server


请高手们帮忙看看是哪的问题？
