nscd(8) 						      System Manager's Manual							   nscd(8)

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, deter-
       mines 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 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 nscd.
