問題描述

使用 remote-ssh 連結遠端機器，發現控制檯會報如下錯誤:

$ ssh [email protected]
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@    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 ECDSA key sent by the remote host is
SHA256:hotsxb/qVi1/ycUU2wXF6mfGH++Yk7WYZv0r+tIhg4I.
Please contact your system administrator.
Add correct host key in
 
 /Users/scott/.ssh/known_hosts to get rid of this message.
Offending ECDSA key in /Users/scott/.ssh/known_hosts:47
ECDSA host key for ec2-192-168-1-1.compute-1.amazonaws.com has changed and you have requested strict checking.
Host key verification failed.

解決方案

刪除掉 known_hosts 中，對應的 ip 或者域名，重新連線之後，輸入賬號密碼即可。

$ vim ~/.ssh/known_hosts
