# Malcontent NSS Module This is a NSS module allowing to perform parental controls when querying the system interfaces for hostname resolution (DNS). A system administrator would install the module and then add it to the `hosts` entry in `/etc/nsswitch.conf`. For instance: ``` hosts: files myhostname malcontent resolve [!UNAVAIL=return] dns ``` Note how `malcontent` precedes both systemd's `resolve` and the libc `dns` modules. Parental control configuration would happen through the Malcontent client or GUI.
