🚩🇨🇳🏹红旗中科 RedFlag Linux（域名服务器）DNS被骇客入侵导致无法上网

难道是国内访问不了 最后我觉得是dns的问题 修改dns需要修改 /etc/resolv.conf 这个文件 参考 更改PVE登录IP管理地址

因为这个主机只装黑群晖 所以安装pve时候 dns默认127.0.0.1没修改酿成这个大错 修改成任意公共DNS 比如114.114.114.114 问题解决！

改为后上传覆盖 系统都无需重启立即生效

Updated the dns ip for public use and it works as below !!!

# Generated by NetworkManager
# nameserver 192.168.1.254
nameserver 114.114.114.114 #Set a public ip dns

下载以上文件，然后复制粘贴到etc/resolv.conf更新该网络管理员文件如下。

sudo chmod 777 -R /etc/resolv.conf
wget https://raw.githubusercontent.com/scibrokes/owner/%E4%B8%96%E5%8D%9A%E9%87%8F%E5%8C%96%E7%A0%94%E7%A9%B6%E9%99%A2/etc/resolv.conf
sudo cp resolv.conf /etc/resolv.conf
sudo rm resolv.conf

[englianhu]

$ sudo chmod 777 -R /etc/resolv.conf | echo '#赢家黄氏江夏堂，点缀全球
nameserver 114.114.114.114' > /etc/resolv.conf

通过以上两行代码，修改网络管理员文件内容更快捷。
