Linux系统重装导致SSH key登录失败

Linux系统重装导致SSH key登录失败

在一台linux机器上ssh远程另外一台linux服务器时候出现:

[root@server .ssh]# ssh 192.0.50.80

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

@    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

97:d3:d4:f1:c9:c6:2e:40:93:b2:a8:70:45:e8:d2:6c.

Please contact your system administrator.

Add correct host key in /root/.ssh/known_hosts to get rid of this message.

Offending key in /root/.ssh/known_hosts:1

RSA host key for 192.0.50.80 has changed and you have requested strict checking.

Host key verification failed.

[root@server .ssh]#

这种情况是因为要ssh的机器上的ssh重新安装或者系统重装了,导致RSA host key 失效,解决方法:

mv /root/.ssh/known_hosts /tmp

即可重新登录
