@    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 a host key has just been changed.

The fingerprint for the ED25519 key sent by the remote host is

SHA256:yDBkBRA7gdiB2ZrRDpZpXaDV5eVeRvFb5yGNwGRNMUU.

Please contact your system administrator.

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

Offending ECDSA key in /Users/mac/.ssh/known_hosts:33

Host key for 192.168.3.251 has changed and you have requested strict checking.

Host key verification failed.

这是因为我们本地的known_hosts保存的主机hostkey记录改变了,导致之前已经记录了连接的服务器的IP及内容,当我们重装系统后,系统的内容变了,我们的记录还是之前的内容。

解决办法:我们只要输入以下的命令代码就可以解决

好了,现在重新ssh吧
