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.
