Automatic overwrite of the resolv. conf file in ubuntu

Resolv In ubuntu. if multiple NICs exist and one of the lan nics is set to dhcp, if the multi-problem resolvconf is installed, it will be responsible for configuring the resolv of the nameserver. clear the conf file. The simplest way is to file/etc/resolvconf/resolv. conf. add the required Domain Name Server to the d/head (or the base or tail files): nameserver xxx. xxx. xxx. xxx then use the command to update: resolvconf-u if the network adapter has a static IP address, you can also modify the/etc/network/interfaces file and append it after the NIC configuration that needs to be set to dns: dns-nameservers xxx. xxx. xxx. xxx and other information have been tossing me for many times until I knocked on man resolvconf :)
