一般是在配置无密码登录时导致，解决方法如下：

修改本机ssh_config文件 ，将GSSAPIAuthentication yse 改为：GSSAPIAuthentication no

[root@bqh-117 ~]# sed -i 's#GSSAPIAuthentication yes#GSSAPIAuthentication no#g' /etc/ssh/ssh_config 
[root@bqh-117 ~]# sed -n 50p /etc/ssh/ssh_config
    GSSAPIAuthentication no

GSSAPIAuthentication的作用：是否允许使用基于GSSAPI的用户认证
