用ssh登录一个机器（换过ip地址），提示输入yes后，屏幕不断出现y，只有按ctrl + c结束
错误是：The authenticity of host 192.168.0.xxx can't be established.
以前和同事碰到过这个问题，解决了，没有记录，这次又碰到了不知道怎么处理，还好有QQ聊天记录，查找到一下，找到解决方案：
执行ssh -o StrictHostKeyChecking=no 192.168.0.xxx就OK
网址是：
//04/1026/
记一下，防止又忘记了，又快到3点了，无数个不眠之夜啊。
/10/11
某天机器又改IP了，ssh后，报：
mmt@FS01:~$ ssh -o StrictHostKeyChecking=no 192.168.0.130
