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
e0:59:1a:4d:52:54:f9:81:a2:f1:ca:11:55:26:74:86.
Please contact your system administrator.
Add correct host key in /home/dinghuaneng/.ssh/known_hosts to get rid of this me
Offending key in /home/dinghuaneng/.ssh/known_hosts:1
RSA host key for 172.16.103.176 has changed and you have requested strict checki
Host key verification failed.
lost connection
操作：在执行scp命令的主机上执行：
vi ~/.ssh/known_hosts
删除IP为172.16.103.176 的行即可。
该现象在虚拟机删除之后重新建立的时候尤其明显，主要是因为原始主机已经存了一份了known_hosts了，需要更新。
