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 a host key has just been changed.

The fingerprint for the ECDSA key sent by the remote host is

07:44:8a:a7:ac:51:52:be:08:b1:be:13:8b:be:79:7c.

Please contact your system administrator.

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

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

ECDSA host key for 192.168.61.137 has changed and you have requested strict checking.

Host key verification failed.

解决方案：

把原来的ssh密钥移除，重新获取密钥

root@kinken:/home/kinken# mv /root/.ssh/known_hosts /tmp/

root@kinken:/tmp# ssh [email protected]
