具体也不知道嘛意思。。在网上搜索了下答案，原来是NDS 的设置问题

解决NDS步骤：

     编辑 etc/resolv.conf,添加 nameserver 202.96.134.133（你的dns），这里我设置成谷歌的NX的 DNS 8.8.8.8

..................................................................................................................................................................................................

 

      # vi /etc/resolv.conf

          nameserver  8.8.8.8

..................................................................................................................................................................................................

保存重启网卡 就OK了

    :wq

    #  service network restart
