ssh远程连接错误

在平时工作中，有时候需要SSH登陆到别的Linux主机上去，但有时候SSH登陆会被禁止，并弹出如下类似提示：

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
 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 is36:68:a6:e6:43:34:6b:82:d7:f4:df:1f:c2:e7:37:cc.Please contact your system administrator.Add correct host key in /u/xlian008/.ssh/known_hosts to get rid of this message.Offending key in /u/xlian008/.ssh/known_hosts:2RSA host key for 135.1.35.130 has changed and you have requested strict checking.Host key verification failed.

有以下两个解决方案：

1. 手动删除修改known_hsots里面的内容；

2. 修改配置文件“~/.ssh/config”，加上这两行，重启服务器。

   StrictHostKeyChecking no

   UserKnownHostsFile /dev/null
