通常是在配置無密碼登陸時致使，解決方法以下：

修改本機ssh_config文件 ，將GSSAPIAuthentication yse 改成：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的做用：是否容許使用基於GSSAPI的用戶認證
