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

SHA256:Wi5PqOrKfGFg0y7Q1svoOtjq4EX/pflROpGZg09EzYc.

Please contact your system administrator.

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

具体情况是，之前家里的二奶开发机装的是ubuntu 16.04，已经使用终端连接过，系统存有指纹备份，发现不一样了，不允许连接，解决办法是。

右键Finder，前往文件夹，/Users/你的用户名

打开终端，输入 defaults write com.apple.finder AppleShowAllFiles -bool true，再按com + alt + esc，选中Finder重启，就可以看到.ssh隐藏文件夹了，右键它，在新的finder里面打开，然后编辑文档known_hosts，删掉之前此ip留下的那一串，然后就可以链接了。
