@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ 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 51:82:00:1c:7e:6f:ac:ac:de:f1:53:08:1c:7d:55:68. Please contact your system administrator. Add correct host key in /Users/isaacalves/.ssh/known_hosts to get rid of this message. Offending RSA key in /Users/isaacalves/.ssh/known_hosts:12 RSA host key for 104.131.16.158 has changed and you have requested strict checking. Host key verification failed.

Cách 1:Just edit ~/.ssh/known_hosts and delete line 12

Offending RSA key in /Users/isaacalves/.ssh/known_hosts:12

Cách 2: ssh-keygen to delete the invalid key

ssh-keygen -R "you server hostname or ip"
