/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; characters up to the
       end of the line are not interpreted by nscd.

       Valid services are passwd, group or hosts.

       logfile debug-file-name
              Specifies  name  of  the  file  to which debug info
              should be written.

       debug-level value
              Sets the desired debug level.

       threads number
              This is the number of how many threads are  started
              and  waiting  for  requests.  At least five threads
              will always be created.

       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  parameter),  this  option   is
              ignored.

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

       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  seconds.  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 seconds. Can result  in  sig­
              nificant performance improvements if there are sev­
              eral 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

              remain a prime number for optimum efficiency.

       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 and /etc/hosts.
