This information is provided as part of the Lynis community project. It is related to Lynis control NAME-4028 and should be considered as-is and without guarantees. Any advice and commands should be tested before implementing them in production environments.

Control details


DNS resolving is part of the network functionality of systems. Properly configured network settings are needed for providing business services. Unix based systems are usually part of a domain. This domain name is the DNS domain name of the company. Lynis tries to determine what domain name this is, by checking several configuration files. In case this control shows up, Lynis was unable to discover it properly. This might indicate a misconfiguration of the server, or an alternative configuration set-up being used. Check the system and network configuration for the possible cause.

How to solve

Check lynis.log file for any hints why no domain name could be found.
