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

05:25:84:ea:dd:92:8d:80:ce:ad:5b:79:58:fe:c9:42.

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:10

RSA host key for 192.168.1.90 has changed
and you have requested strict checking.

Host key verification failed.

解决方法:

vi ~/.ssh/known_hosts

进入此目录，删除192.168.1.90的相关rsa的信息即可.

或
者删除这个文件

cd ~/.ssh/

rm known_hosts

注：我在192.168.1.90机器上删除没用，在连接端删除才行的
