同事的ssh scp无法连接到本地机器

ssh scp 无法连接到某台机器

使用SSH登录另外一台机器，
#ssh 172.16.16.38
得到如下输出
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@     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 the RSA host key has just been changed.

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

在网上查说是ssh未安装完全，如openssh-server,openssh-cli 未安装等说法，安装后依然未解决

后终于在网上找出了原因：

因为在本地机器上曾经用SSH登录过这台远程计算机，因而留下了known_hosts的记录，在远程计算机重新安装系统后不能够通过鉴权。 删除~/.ssh/known_hosts中对应的项目，问题获得解决。
