nscd(5) -- Linux man page
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, 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.
