MAC下ssh报错，清除原有ssh密钥方法

mac的终端下面使用ssh user@localhost输入密码不能正常登录解决

 

今天回来后发现系统突然很奇怪，以前在mac的终端下面使用ssh user@localhost输入密码就可以连接到远程的SSH服务器，今天连接的时候老是提示如下错误：

 

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可以了。

 

解决方法：

 

ssh-keygen -R 192.168.1.203(你远程服务器的IP)
