NAME
       /usr/sbin/nscd - name service cache daemon

DESCRIPTION
       Nscd  is	 a daemon that provides a cache for the most common name ser-
       vice 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	 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.
