Offending RSA key in /Users/liuhang/.ssh/known_hosts:7

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. 

执行ssh  -o StrictHostKeyChecking=no  192.168.0.xxx　就OK

 

某天机器又改IP了，ssh后，报：

mmt@FS01:~$ ssh  -o StrictHostKeyChecking=no  192.168.0.130

 注意这句

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

执行：

mv  /home/mmt/.ssh/known_hosts known_hosts.bak

再连：

ssh  -o StrictHostKeyChecking=no  192.168.0.130

OK了!
