mac的終端下面使用ssh user@localhost輸入密碼 不能正常登陸

今天回來後發現系統忽然很奇怪，之前在mac的終端下面使用ssh user@localhost輸入密碼就能夠鏈接到遠程的SSH服務器，今天鏈接的時候總是提示以下錯誤：

KENFORFORLIN:~ kenforstar$ sudo ssh root@192.168.1.203 Password: @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @    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. The fingerprint for the RSA key sent by the remote host is ea:24:31:8d:03:07:36:db:2f:74:15:5d:58:67:a3:5b. Please contact your system administrator. Add correct host key in /var/root/.ssh/known_hosts to get rid of this message. Offending key in /var/root/.ssh/known_hosts:1 RSA host key for 192.168.1.203 has changed and you have requested strict checking. Host key verification failed.

只要清除老的公鑰信息就能夠了。

解決方法：ssh-keygen -R 192.168.1.203(你遠程服務器的IP)
