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 the RSA host key has just been changed.
The fingerprint for the RSA key sent by the remote host is
64:89:de:58:fc:0a:9e:26:5f:4f:a2:e9:a3:f8:ee:f9.
Please contact your system administrator.
Add correct host key in /root/.ssh/known_hosts to get rid of this message.
Offending key in /root/.ssh/known_hosts:2
RSA host key for 192.168.0.2 has changed and you have requested strict checking.
Host key verification failed.
 이렇게 나오는군요..
 이 RSA값을 어케해야 원래 값으로 돌려보낼수 있을까요?
 접속을 하고 싶습니다.. 접속! ㅜ,ㅡ
 고수님들의 도움이 필요합니다.--화이
