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

4b:ab:fa:8e:dd:87:68:45:58:a6:da:49:8f:55:18:73.

Please contact your system administrator.

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

Offending ECDSA key in /home/orion/.ssh/known_hosts:2

  remove with: ssh-keygen -f "/home/orion/.ssh/known_hosts" -R 192.168.227.5

ECDSA host key for 192.168.227.5 has changed and you have requested strict checking.

Host key verification failed.

解决方法:

在正在操作的机器上执行

vi ~/.ssh/known_hosts

进入此目录，删除的192.168.227.5.**相关rsa的信息即可.

或者删除这个文件

cd ~/.ssh/

rm known_hosts
