WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!

今天远程ssh登陆碰见下边提示：

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ 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 the RSA host key has just been changed. The fingerprint for the RSA key sent by the remote host is da:f4:a0:89:a6:2b:87:86:69:33:59:ad:eb:da:66:3a. 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 10.8.59.194 has changed and you have requested strict checking. Host key verification failed.

解决方法：打开文件/root/.ssh/known_hosts ，删除与远程主机有关的信息便可。我的缘由是因为远程主机重装了系统。
