NAME<\/a> nscd.conf \u2212 name service cache daemon configuration file<\/p>\n The file \/etc\/nscd.conf<\/i> is read from nscd<\/b>(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.<\/p>\n Valid services are passwd<\/i>, group<\/i>, hosts<\/i>, services<\/i>, or netgroup<\/i>.<\/p>\n logfile<\/b> debug-file-name<\/i><\/p>\n Specifies name of the file to which debug info should be written.<\/p>\n debug\u2212level<\/b> value<\/i><\/p>\n Sets the desired debug level. The default is 0.<\/p>\n threads<\/b> number<\/i><\/p>\n This is the number of threads that are started to wait for requests. At least five threads will always be created.<\/p>\n max\u2212threads<\/b> number<\/i><\/p>\n Specifies the maximum number of threads. The default is 32.<\/p>\n server\u2212user<\/b> user<\/i><\/p>\n If this option is set, nscd will run as this user and not as root. If a separate cache for every user is used (\u2212S parameter), this option is ignored.<\/p>\n stat\u2212user<\/b> user<\/i><\/p>\n Specifies the user who is allowed to request statistics.<\/p>\n reload\u2212count<\/b> unlimited | number<\/i><\/p>\n Limit on the number of times a cached entry gets reloaded without being used before it gets removed. The default is 5.<\/p>\n paranoia<\/b> Enabling paranoia mode causes nscd to restart itself periodically. The default is no.<\/p>\n restart\u2212interval<\/b> time<\/i><\/p>\n Sets the restart interval to time<\/i> seconds if periodic restart is enabled by enabling paranoia<\/b> mode. The default is 3600.<\/p>\n enable\u2212cache<\/b> service Enables or disables the specified service<\/i> cache. The default is no.<\/p>\n positive\u2212time\u2212to\u2212live<\/b> service value<\/i><\/p>\n Sets the TTL (time-to-live) for positive entries (successful queries) in the specified cache for service<\/i>. Value<\/i> is in seconds. Larger values increase cache hit rates and reduce mean response times, but increase problems with cache coherence.<\/p>\n negative\u2212time\u2212to\u2212live<\/b> service value<\/i><\/p>\n Sets the TTL (time-to-live) for negative entries (unsuccessful queries) in the specified cache for service<\/i>. Value<\/i> 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.<\/p>\n suggested\u2212size<\/b> service value<\/i><\/p>\n This is the internal hash table size, value<\/i> should remain a prime number for optimum efficiency. The default is 211.<\/p>\n check\u2212files<\/b> service Enables or disables checking the file belonging to the specified service<\/i> for changes. The files are \/etc\/passwd<\/i>, \/etc\/group<\/i>, \/etc\/hosts<\/i>, \/etc\/services<\/i>, and \/etc\/netgroup<\/i>. The default is yes.<\/p>\n persistent<\/b> service Keep the content of the cache for service<\/i> over server restarts; useful when paranoia<\/b> mode is set. The default is no.<\/p>\n shared<\/b> service The memory mapping of the nscd databases for service<\/i> is shared with the clients so that they can directly search in them instead of having to ask the daemon over the socket each time a lookup is performed. The default is no.<\/p>\n max\u2212db\u2212size<\/b> service bytes<\/i><\/p>\n The maximum allowable size, in bytes, of the database files for the service<\/i>. The default is 33554432.<\/p>\n auto\u2212propagate<\/b> service When set to no<\/i> for passwd<\/i> or group<\/i> service, then the .byname<\/i> requests are not added to passwd.byuid<\/i> or group.bygid<\/i> cache. This can help with tables containing multiple records for the same ID. The default is yes. This option is valid only for services passwd<\/i> and group<\/i>.<\/p>\n The default values stated in this manual page originate from the source code of nscd<\/b>(8) and are used if not overridden in the configuration file. The default values used in the configuration file of your distribution might differ.<\/p>\n
