在 Ubuntu 中忽略来自 DHCP 服务器的 DNS

Question

我DNS在/etc/resolvconf/resolv.conf.d/base文件中设置了静态：

nameserver 8.8.8.8
nameserver 8.8.4.4

但是我的电脑仍然从 DHCP 获取 DNS，这是我的/etc/resolv.conf：

nameserver 192.168.100.2 
nameserver 8.8.8.8
nameserver 8.8.4.4

如何忽略DNS从DHCP服务器获取？

Answer 1

您可以将此行添加到您的/etc/dhcp/dhclient.conf：

supersede domain-name-servers 8.8.8.8, 8.8.4.4;

然后重新启动网络或运行dhclient以进行更改。

来自man dhclient.conf：

The supersede statement

       supersede [ option declaration ];

       If for some option the client should always  use  a  locally-configured
       value  or  values rather than whatever is supplied by the server, these
       values can be defined in the supersede statement.
