mac的终端下面使用ssh user@localhost输入密码 不能正常登陆

今天回来后发现系统忽然很奇怪，之前在mac的终端下面使用ssh user@localhost输入密码就能够链接到远程的SSH服务器，今天链接的时候总是提示以下错误：

KENFORFORLIN:~ kenforstar$ sudo ssh root@192.168.1.203 Password: @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @    WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!     @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY! Someone could be eavesdropping on you right now (man-in-the-middle attack)! It is also possible that the RSA host key has just been changed. The fingerprint for the RSA key sent by the remote host is ea:24:31:8d:03:07:36:db:2f:74:15:5d:58:67:a3:5b. Please contact your system administrator. Add correct host key in /var/root/.ssh/known_hosts to get rid of this message. Offending key in /var/root/.ssh/known_hosts:1 RSA host key for 192.168.1.203 has changed and you have requested strict checking. Host key verification failed.

只要清除老的公钥信息就能够了。

解决方法：ssh-keygen -R 192.168.1.203(你远程服务器的IP)
