       nscd.conf - name service cache daemon configuration


       The  nscd.conf  file contains the configuration information for nscd(1M). Each line speci-
       fies either an attribute and a value, or an attribute, cachename, and a value. Fields  are
       separated  either  by SPACE or TAB characters. A `#' (number sign) indicates the beginning
       of a comment; characters up to the end of the line are not interpreted by nscd.

       cachename  is  represented  by  hosts,  ipnodes,  passwd,  group,  exec_attr,   prof_attr,
       user_attr,  ethers, rpc, protocols, networks, bootparams, audit_user, auth_attr, services,
       netmasks, printers, or project.

       The attribute field supports the following:

       check-files cachename value

	   Enables or disables checking  the  file  belonging  to  the	specified  cachename  for
	   changes.  If  enabled  (which is the default), changes in the corresponding file cause
	   the cache to be invalidated within 10 seconds. Can be disabled if files are never mod-
	   ified  for  a slight performance boost, particularly over NFS. value may be either yes
	   or no.

       debug-level value

	   Sets the debug level desired. value may range from 0 (the default) to 10. Use of  this
	   option causes nscd(1M) to run in the foreground and not become a daemon. Note that the
	   output of the debugging command is not likely to  remain  the  same	from  release-to-
	   release; scripts should not rely on its format.

       enable-cache cachename value

	   Enables or disables the specified cache. value may be either yes or no.

       enable-per-user-lookup value

	   Enables  or	disables  the  ability of nscd to create a per-user nscd. A per-user nscd
	   performs per-user lookups and manages the per-user cache. The per-user  lookups  might
	   not be possible if the corresponding name service switch backends do not support it or
	   are not configured to do so. The value of this attribute can be either yes or no.

       keep-hot-count cachename value

	   This attribute allows the administrator to set the number of entries  nscd(1M)  is  to
	   keep  current in the specified cache. value is an integer number which should approxi-
	   mate the number of entries frequently used during the day.

       logfile debug-file-name

	   Specifies name of the file to which debug info should be  written.  Use  /dev/tty  for
	   standard output.

       maximum-per-user-nscd value

	   Sets  the maximum number of per-user nscds that can be created and managed by the main
	   nscd daemon. The value is an integer.

       negative-time-to-live cachename value

	   Sets the time-to-live for negative entries (unsuccessful  queries)  in  the	specified
	   cache. value is in integer seconds. Can result in significant performance improvements
	   if there are several files owned by uids (user IDs) not in system databases; should be
	   kept small to reduce cache coherency problems.

       per-user-nscd-time-to-live value

	   Sets  the  time-to-live  value for a per-user nscd based on the last time the per-user
	   nscd was active. The value is an integer that specifies a number of seconds.

       positive-time-to-live cachename value

	   Sets the time-to-live for positive  entries	(successful  queries)  in  the	specified
	   cache.  value is in integer seconds. Larger values increase cache hit rates and reduce
	   mean response times, but increase problems with cache coherence. Note that sites  that
	   push  (update)  NIS maps nightly can set the value to be the equivalent of 12 hours or
	   more with very good performance implications.

       suggested-size cachename value

	   Sets the suggested number of hash buckets  in  the  specified  cache.  This	parameter
	   should  be  changed	only  if the number of entries in the cache exceeds the suggested
	   size by more than a factor of four or five. Since this  is  the  internal  hash  table
	   size, value should remain a prime number for optimum efficiency.

	   This  attribute  is	obsolete  and  will  be  silently ignored. nscd now automatically
	   adjusts the hash table size.
