【问题解决】Address *.* maps to localhost, but this does not map back to the address - POSSIBLE BREAK-IN ATTEMPT!

在多台机器之间建立无密码登录后，执行命令时候，遇到一个问题：

Address 172.17.118.77 maps to localhost, but this does not map back to the address - POSSIBLE BREAK-IN ATTEMPT!
Address 172.17.118.77 maps to localhost, but this does not map back to the address - POSSIBLE BREAK-IN ATTEMPT!

 

处理办法：

修改本机ssh_config文件 

[root@h3 ~]# vim /etc/ssh/ssh_config 

GSSAPIAuthentication no 

 

修改该文件第50行，并保存；

 

 之后重新测试，问题解决。
