SYNOPSIS

hosts: resinit

DESCRIPTION

The nss_resinit is a module for the nsswitch subsystem which makes resolver(3) reread resolv.conf(5) when it is updated. In the traditional implementation of resolver(3) it is initialized by the application once and never reread resolv.conf(5) after that even if the file is updated. This module is useful especially when name servers in resolv.conf(5) are changed frequently as seen in mobile environment.

To activate nss_resinit, resinit keyword is required before dns keyword in hosts entry of /etc/nsswitch.conf. For example:

    hosts: resinit files dns

Once resolv.conf(5) was reread, nss_resinit prevents from rereading resolv.conf(5) during certain period to intend to reduce overhead for checking a modified time of resolv.conf(5). This interval can be changed by setting kenv(2) variable nss_resinit_interval. The default interval is 10 seconds.

FILES
