ssh报错SOMETHING NASTY

--------------------------------------------------------------------------------


老师;
我在调hosts.deny关于ssh的部分，真奇怪，突然ssh就不行了，现在我已经把hosts.deny,hosts.allow里的关于ssh的部分都屏蔽了，还是不行。
我的环境 station2 139.24.205.98
station3 139.24.205.100
急死我了，请教！



[root@station2 ~]# ssh 139.24.205.100

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.

晨想

作业？：）。

1。服务器的公匙改了。
2。连接被劫持(man-in-the-middle)。
3。你的 host_known 中已经有一条记录，但是和服务器的记录不一样。
