NAME
nsquery - query the Name Service Switch backend libraries
SYNOPSIS
nsquery lookup_type lookup_query [lookup_policy]
DESCRIPTION
nsquery is used to find the Name Service that returned the response to a
getaddrinfo()
, gethost-
byname()
, gethostbyaddr()
, getnameinfo()
, getpwnam(), getpwuid(), getgrnam(),
or
getgrgid() function call. This application is Name Service Switch aware and follows the lookup poli-
cies in /etc/nsswitch.conf
. The supported lookup_type values are:
hosts Used to resolve host name or IP Address lookups.
passwd Used to resolve user name or UID lookups.
group Used to resolve group name or GID lookups.
ipnodes Used to resolve host name or IP Address lookups. Only IPv6 and IPv4-mapped IPv6
address will be displayed for host name lookups.
The lookup_query can either be a host name, IP Address (IPv4 only), user name, user ID, group name, or
group ID.
The lookup_policy must be a valid lookup policy described in nsswitch.conf(4). If the policy is invalid, the
system default policy will be used. The default values for lookup_policy are:
hosts dns [NOTFOUND=return] nis [NOTFOUND=return] files
passwd files nis
group files nis
ipnodes dns [NOTFOUND=return] files
nsquery will display the lookup policy being used, the name of the service being queried, and the result of
the query.
