NAME

     nscd -- name service caching daemon

SYNOPSIS

     nscd [OPTION...]

DESCRIPTION

     Nscd caches libc-issued requests to the Name Service. If retrieving NSS data is fairly expensive, nscd is able to speed up consecutive access
     to the same data dramatically and increase overall system performance.  Nscd should be run at boot time by /etc/init.d/nscd.

OPTIONS

     -d, --debug
	     Do not fork and display messages on the current tty.

     -f, --config-file NAME
	     Read configuration data from NAME.  For a description of the config file format, see nscd.conf(5).

     -g, --statistic
	     Print current configuration statistics.

     -i, --invalidate TABLE
	     Invalidate the specified TABLE, i. e. forget all data cached therein. This should be used if the database storing this information
	     has been changed.

     -K, --shutdown
	     Quit a running nscd process.

     -S, --secure TABLE
	     Use a separate cache for each user.

     -t, --nthreads NUMBER
	     Start NUMBER threads. This denotes the maximum number of requests that can be handled simultaneously. The default is set in the con-
	     figuration file. (See nscd.conf(5).)

     -?, --help
	     Print the list of available options.

     --usage
	     Print a short usage message.

     -V, --version
	     Print program version.

FILES

     /etc/nscd.conf
	     Nscd configuration file. See nscd.conf(5) for more information.

     /etc/nsswitch.conf
	     Name Service Switch configuration. See nsswitch.conf(5) for more information.

NAME

       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 caching 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 others.

       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.

OPTIONS

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

NOTES

       The daemon will try to watch for changes in configuration files appropriate for each database (e.g., /etc/passwd for the passwd database or
       /etc/hosts and /etc/resolv.conf for the hosts database), and flush the cache when these are changed.  However, this will happen only  after
       a  short  delay	(unless the inotify(7) mechanism is available and glibc 2.9 or later is available), and this auto-detection does not cover
       configuration files required by nonstandard NSS modules, if any are specified in /etc/nsswitch.conf.  In that case, you	need  to  run  the
       following command after changing the configuration file of the database so that nscd invalidates its cache:

	   $ nscd -i <database>
