       /usr/sbin/nscd - name service cache daemon

       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  accesses of the passwd(5), group(5), and
       hosts(5) databases through standard libc	 interfaces,  such  as	getpw-
       nam(3),	getpwuid(3),  getgrnam(3),  getgrgid(3), gethostbyname(3), and

       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.   Note  that	 the  shadow  file  is
       specifically  not  cached.   getspnam(3)	 calls	remain	uncached  as a
       result.	As a result of this behavior there is not possible  to	change
       non-nscd user to another non-nscd user via su service when nscd is run-

       --help will give you a list with all options and what they do.

       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.

       nscd.conf(5), nsswitch.conf(5)

       nscd was written by Thorsten Kukuk and Ulrich Drepper.
