/usr/sbin/nscd - name service cache daemon
DESCRIPTION
Nscd is a daemon that provides a cache for the most common
name service requests. The default configuration file
/etc/nscd.conf determines the behavior of the cache dae
mon. See nscd.conf(5).
Nscd provides cacheing for 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. Each cache has a separate TTL
(time-to-live) for its data; modifying the local database
( /etc/passwd, and so forth) causes that the cache becomes
invalidated within fifteen seconds. Note that the shadow
file is specifically not cached. getspnam(3) calls remain
uncached as a result.
OPTIONS
--help Will give you a list with all options and what they
do.
NOTES
Nscd doesn't know anything about the underlaying 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/nss
witch.conf(5) to use DNS for host lookups. In such a case,
you need to restart nscd.
