NAME
/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 daemon. 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), getp-
wuid(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 the cache to become
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 ser-
vice. 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 nscd.
