今天在服务器上执行远程操作命令出现以下的问题:
[root@www ~]# ssh 205.209.161.**

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
6c:74:2a:d5:ae:2b:76:51::.
Please contact your system administrator.
Add correct host key in /root/.ssh/known_hosts to get rid of this message.

解决方法:
在正在操作的机器上执行
vi ~/.ssh/known_hosts
进入此目录，删除的205.209.161.**相关rsa的信息即可.
或者删除这个文件
cd ~/.ssh/
rm known_hosts
