ssh 命令不能连接到另一台linux服务器时解决方案

在linux下面提示如下：

 

linux:~ # ssh 10.81.36.108

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

@    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

72:13:0c:88:37:c4:6d:bc:e3:0d:6d:50:34:ca:c8:ac.

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 10.81.36.108 has changed and you have requested strict checking.

Host key verification failed.

 

首先检测目的服务器的主机名是否和hosts文件映射一直，如果不一致请更改为一致后

#hostname 主机名

 

同时检测当前源服务器的/root/.ssh/know_hosts文件时候有目的主机地址的16进制解码，清除重新在连接即可成功
