@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ 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 e7:f4:18:2c:8c:d7:90:a7:33:21:b0:3c:05:4d:3c:06. Please contact your system administrator. Add correct host key in /usr01/.ssh/known_hosts to get rid of this message. Offending RSA key in /usr01/.ssh/known_hosts:6 RSA host key for 192.168.111.200 has changed and you have requested strict checking. Host key verification failed.
解决之道
ssh-keygen -R 192.168.111.200
