Linux清除原有ssh密钥方法

Linux清除原有ssh密钥方法
1.问题现象

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。

2.解决方法

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