NSS-RESOLVE(8)                   nss-resolve                  NSS-RESOLVE(8)

NAME         top

       nss-resolve, libnss_resolve.so.2 - Provide hostname resolution via
       systemd-resolved.service

SYNOPSIS         top

       libnss_resolve.so.2

DESCRIPTION         top

       nss-resolve is a plug-in module for the GNU Name Service Switch (NSS)
       functionality of the GNU C Library (glibc) enabling it to resolve
       host names via the systemd-resolved(8) local network name resolution
       service. It replaces the nss-dns plug-in module that traditionally
       resolves hostnames via DNS.

       To activate the NSS module, add "resolve" to the line starting with
       "hosts:" in /etc/nsswitch.conf. Specifcally, it is recommended to
       place "resolve" early in /etc/nsswitch.conf' "hosts:" line (but after
       the "files" or "mymachines" entries), right before the "dns" entry if
       it exists, followed by "[!UNAVAIL=return]", to ensure DNS queries are
       always routed via systemd-resolved(8) if it is running, but are
       routed to nss-dns if this service is not available.

EXAMPLE         top

       Here is an example /etc/nsswitch.conf file that enables nss-resolve
       correctly:

           passwd:         compat mymachines systemd
           group:          compat mymachines systemd
           shadow:         compat

           hosts:          files mymachines resolve [!UNAVAIL=return] dns myhostname
           networks:       files

           protocols:      db files
           services:       db files
           ethers:         db files
           rpc:            db files

           netgroup:       nis
