安装环境 : 虚拟机
虚拟机版本 ：vmware 15.0.0
虚拟机网卡设置：桥接


windows用的真的心累了，C盘100G都满了，不想再用windows，搜索了下选定了deebin，想虚拟机安装试一下，开发工具什么的能安装我就重装系统了。

现在的问题是：无法解析DNS



我个人做过如下检查：


1.dns配置正常

root@liyao-PC:/home/liyao/Desktop# cat /etc/resolv.conf
# Generated by NetworkManager
nameserver 172.19.27.251
nameserver 114.114.114.114

2.网络连通性正常。
root@liyao-PC:/home/liyao/Desktop# ping 114.114.114.114
PING 114.114.114.114 (114.114.114.114) 56(84) bytes of data.
64 bytes from 114.114.114.114: icmp_seq=2 ttl=60 time=20.6 ms
64 bytes from 114.114.114.114: icmp_seq=3 ttl=68 time=20.8 ms
64 bytes from 114.114.114.114: icmp_seq=4 ttl=90 time=26.0 ms

rtt min/avg/max/mdev = 20.661/22.522/26.010/2.471 ms



3.与dns服务器53端口连通性测试正常
root@liyao-PC:/home/liyao/Desktop# telnet 114.114.114.114 53
Trying 114.114.114.114...
Connected to 114.114.114.114.
Escape character is '^]'.
^C^]
telnet> quit
Connection closed.



4.其他操作

包括重启网卡，停止networkManager，重装系统全部无效





希望能协助看下是什么问题
