The file /etc/host.conf contains configuration information specific to the resolver library. It should contain one configuration keyword per line, followed by appropriate configuration information. The keywords recognized are order, trim, multi, nospoof, spoof, and reorder. These keywords are described below.
There are six environment variables that can be used to allow users to override the behavior which is configured in /etc/host.conf.
The following differences exist compared to the original implementation. A new command spoof and a new environment variable RESOLV_SPOOF_CHECK can take arguments like off, nowarn and warn. Line comments can appear anywhere and not only at the beginning of a line.
This page is part of release 3.74 of the Linux man-pages project. A description of the project, information about reporting bugs, and the latest version of this page, can be found at http://www.kernel.org/doc/man-pages/.
