/etc/nscd.conf - name service cache daemon configuration file
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, 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 threads that are started
to wait 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 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.
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.
nscd(8)
nscd was written by Thorsten Kukuk and Ulrich Drepper.
