!!! Overview
[{$pagename}], [Name Service Cache Daemon], is a [daemon] that provides a [cache] for the most common [Name Service Switch] requests. The default configuration file, /etc/nscd.conf, determines the behavior of the cache daemon.
[{$pagename}] provides caching for accesses of the [passwd](5), [group](5), and hosts(5) databases through standard libc interfaces, such as getpwnam(3), getpwuid(3), getgrnam(3), getgrgid(3), gethostbyname(3), and others.
There are two caches for each database: a positive one for items found, and a negative one for items not found. Each cache has a separate [TTL] ([Time To Live]) period for its [data].
%%information
the [Shadow] file is specifically not cached. getspnam(3) calls remain uncached as a result.
%%
%%information
Some Redhat systems maybe using [SSSD] instead of [{$pagename}].

!! Notes
[{$pagename}] doesn't know anything about the underlying [protocols] for a service. This also means, that if you change /etc/resolv.conf for [DNS] queries, nscd will continue to use the old one if you have configured /etc/nsswitch.conf to use [DNS] for host lookups. In such a case, you need to restart [{$pagename}].
