NSCD.CONF(5)		   Linux Programmer's Manual		  NSCD.CONF(5)

NAME
       /etc/nscd.conf - name service cache daemon configuration file

DESCRIPTION
       The  file  /etc/nscd.conf  is  read from nscd(8) at startup.  Each line
       specifies either an attribute and a value, or  an  attribute,  service,
       and  a  value.  Fields are separated either by SPACE or TAB characters.
       A '#' (number sign) indicates the beginning  of	a  comment;  following
       characters, up to the end of the line, are not interpreted by nscd.

       Valid services are passwd, group, hosts, services or netgroup.

       logfile debug-file-name
	      Specifies	 name  of the file to which debug info should be writ‐
	      ten.

       debug-level value
	      Sets the desired debug level.  The default is 0.

       threads number
	      This is the number of threads  that  are	started	 to  wait  for
	      requests.	 At least five threads will always be created.

       max-threads number
	      Specifies the maximum number of threads.	The default is 32.

       server-user user
	      If  this	option	is  set, nscd will run as this user and not as
	      root.  If a separate cache for every user is  used  (-S  parame‐
	      ter), this option is ignored.

       stat-user user
	      Specifies the user who is allowed to request statistics.

       reload-count unlimited | number
	      Limit  on the number of times a cached entry gets reloaded with‐
	      out being used before it gets removed.  The default is 5.

       paranoia <yes|no>
	      Enabling paranoia mode causes nscd to  restart  itself  periodi‐
	      cally.  The default is no.

       restart-interval time
	      Sets the restart interval to time seconds if periodic restart is
	      enabled by enabling paranoia mode.  The default is 3600.

       enable-cache service <yes|no>
	      Enables or disables the specified service cache.	The default is
	      no.

       positive-time-to-live service value
	      Sets  the	 TTL  (time-to-live)  for positive entries (successful
	      queries) in the specified cache for service.  Value is  in  sec‐
	      onds.   Larger  values  increase cache hit rates and reduce mean
	      response times, but increase problems with cache coherence.

       negative-time-to-live service value
	      Sets the TTL (time-to-live) for negative	entries	 (unsuccessful
	      queries)	in  the specified cache for service.  Value is in sec‐
	      onds.  Can result in  significant	 performance  improvements  if
	      there  are  several files owned by UIDs (user IDs) not in system
	      databases (for example untarring the  Linux  kernel  sources  as
	      root); should be kept small to reduce cache coherency problems.

       suggested-size service value
	      This  is	the  internal  hash  table size, value should remain a
	      prime number for optimum efficiency.  The default is 211.

       check-files service <yes|no>
	      Enables or disables checking the file belonging to the specified
	      service  for  changes.   The  files are /etc/passwd, /etc/group,
	      /etc/hosts, /etc/services and  /etc/netgroup.   The  default  is
	      yes.

       persistent service <yes|no>
	      Keep  the content of the cache for service over server restarts;
	      useful when paranoia mode is set.	 The default is no.

       shared service <yes|no>
	      The memory mapping of the nscd databases for service  is	shared
	      with  the	 clients  so  that  they  can  directly search in them
	      instead of having to ask the daemon over the socket each time  a
	      lookup is performed.  The default is no.

       max-db-size service bytes
	      The  maximum allowable size, in bytes, of the database files for
	      the service.  The default is 33554432.

       auto-propagate service <yes|no>
	      When set to no for passwd or group  service,  then  the  .byname
	      requests	are  not  added	 to passwd.byuid or group.bygid cache.
	      This can help with tables containing multiple  records  for  the
	      same  ID.	  The  default	is yes.	 This option is valid only for
	      services passwd and group.
