@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
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
87:13:b0:85:de:53:7e:17:04:73:05:9f:40:33:62:db.
Please contact your system administrator.
Add correct host key in /home/kappa/.ssh/known_hosts2 to get rid of this message.
Offending key in /home/kappa/.ssh/known_hosts2:3
RSA host key for 164.125.144.140 has changed and you have requested strict checking.
 외부에서 이렇게 안으로 접속하려고 ssh를 사용하면 위와 같은 메세지가 나옵니다. 어떻게
