/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.
