To activate the NSS modules, add myhostname to the line starting with
hosts: in /etc/nsswitch.conf.
- It is recommended to place myhostname either between resolve
- and "traditional" modules like dns, or after them. In the first version, well-known
- names like localhost and the machine hostname are given higher priority than the
- external configuration. This is recommended when the external DNS servers and network are not absolutely
- trusted. In the second version, external configuration is given higher priority and
- nss-myhostname only provides a fallback mechanism. This might be suitable in closely
- controlled networks, for example on a company LAN.
+ It is recommended to place myhostname after file and before dns.
+ This resolves well-known hostnames like localhost
+ and the machine hostnames locally. It is consistent with the behaviour
+ of nss-resolve, and still allows overriding via
+ /etc/hosts.
+
+ Please keep in mind that nss-myhostname (and nss-resolve) also resolve
+ in the other direction — from locally attached IP adresses to
+ hostnames. If you rely on that lookup being provided by DNS, you might
+ want to order things differently.
