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.
The fingerprint for the RSA key sent by the remote host is
a5:1c:99:1f:fa:d7:1e:76:8b:0a:67:eb:4f:90:24:7a.
Please contact your system administrator.
Add correct host key in /root/.ssh/known_hosts to get rid of this message.
Offending key in /root/.ssh/known_hosts:1
RSA host key for 192.168.1.105 has changed and you have requested strict checking.
Host key verification failed.

搜索得到如下解决:

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。
