登录虚拟机时遇到了这个警告：
zz@server5:~/temp/testlist$ ssh zz@10.0.11.38 @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ 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 a host key has just been changed.

Add correct host key in /home/zz/.ssh/known_hosts to get rid of this message.

Host key verification failed. zz@server5:我本地的ip是10.0.11.125，目标及是10.0.11.38 于是去搜了一下，说是打开
~/.ssh/known_hosts然后从里面找到目标地址删掉，具体到我也就是从里面找到10.0.11.38的那一行信息删掉，但是我打开一看傻眼了，里面都是加密过的内容，完全没有明文的10.0.11.38字符串，这怎么删？
再接着搜，找到了使用下面命令：
ssh-keygen -R 10.0.11.38于是照着操作了一下，然后在ssh就可以了。 于是就赶快来写这篇日志，就在复制开始的那一段警告信息时，我仔细看了一下，突然发现，它的警告里已经有解决方法了。草草草草草。
