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 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.
