FC2telnet登陆局域网中一台RH9机器，root密码正确

FC2下telnet登陆局域网中一台RH9机器，root登不上，密码绝对正确，但是可以用普通用户登上去，然后su到root用户，那为什么不能直接以root身份telnet到那台机器上那？各位高手教教小弟吧，多谢啦！下面是登陆的界面，上面说的 Escape character is '^]'. 不知道指的是什么，是不是ctrl+c啊？
[root@FC2 root]# telnet 211.84.93.251
Trying 211.84.93.251...
Connected to 211.84.93.251.

If I remember correctly, login as root is prohibited by default via telnet.  However, you may configure something, which I have already forgotten, to make it work.
