NETW-2704 - Nameserver configuration

(Networking)

This information is provided as part of the Lynis community project. It is related to Lynis control NETW-2704 and should be considered as-is and without guarantees. Any advice and commands should be tested before implementing them in production environments.

Description

Nameservers, or DNS servers, are being used to do host resolving. They resolve a hostname like www.google.com into an IP address like 74.135.133.72. If one or more nameservers are not working as expected, it might influence the performance of the system and result in other unexpected issues.

How to solve

Add additional DNS servers to the resolving configuration, which is usually /etc/resolv.conf, or part of the networking scripts. See this file if the configuration or the networking script is the original source to be changed.
