@    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 RSA key sent by the remote host is

9b:2d:4f:ec:26:86:55:37:67:f1:26:0d:e9:13:09:23.

Please contact your system administrator.

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

Offending RSA key in /Users/byeongyeong-yeon/.ssh/known_hosts:2

RSA host key for 1.234.79.83 has changed and you have requested strict checking.

Host key verification failed.

ssh 접속할려하면 위와같은 에러를 뿜어낼때가 있다..

당황스럽다 갑자기

ssh-keygen -R [ IP or DomainName]


ex) ssh-keygen -R 110.110.110.110

해결방법은 이렇다.

그러고 다시 ssh를 접속하면 Are you sure you want to continue connecting (yes/no)? 라고 뜨는데 yes해주면 정상접속 된다.
