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 RSA key sent by the remote host is

SHA256:這裏每一個人都不一樣

Please contact your system administrator.

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

會出現這些信息是由於，第一次SSH鏈接時，會生成一個認證，儲存在客戶端（也就是用SSH連線其餘電腦的那個，本身操做的那個）中的known_hosts，可是若是服務器驗證過了，認證資訊固然也會更改，服務器端與客戶端不一樣時，就會跳出錯誤啦～所以，只要把電腦中的認證資訊刪除，連線時從新生成，就一切完美啦～要刪除很簡單，只要在客戶端輸入一個指令

ssh-keygen -R +輸入服務器的IP複製代碼

接下來再次鏈接一次，會出現

Are you sure you want to continue connecting (yes/no)?複製代碼

輸入yes，
就完成鏈接啦！同時，新的認證也生成了
