开启dns.py,我安装了python
2.7环境,修改网卡dns为127.0.0.1,进入nslookup,查询如下:
C:\Users\ggcall>nslookup
DNS request timed out.
timeout was 2 seconds.
默认服务器: UnKnown
Address: 127.0.0.1
> www.sina.com
服务器: UnKnown
Address: 127.0.0.1
DNS request timed out.
timeout was 2 seconds.
DNS request timed out.
timeout was 2 seconds.
DNS request timed out.
timeout was 2 seconds.
DNS request timed out.
timeout was 2 seconds.
*** 请求 UnKnown 超时
dns.py错误如下:
----------------------------------------

return resp

----------------------------------------
请问是什么问题?
