SSH 连接问题！！！

jemball

我用windows的ssh client连接到rhel4.1的ssh服务器，出现下面的提示对话框：

Either the administrator of the remote host computer has changed the host identification, or The ssh protocol has been upgraded from SSH1 to SSH2, or SOMEONE COULD BE EAVESDROPPING ON YOU RIGHT NOW (man-in-the-middle attack). It is NOT RECOMMENDED to connect to the remote host computer until you have contacted the system administrator and found out why the host identification has changed. The fingerprint of the host public key is "XXXXXXXXXXXXXXXXX"...

当我点击“是”之后，输入密码，可以看到服务器上的密码验证已通过（因为看到远程机/etc/profile已经被执行），但下面就是不出命令行。就是说，我没法执行命令，谁帮帮我？
