etcnscdconf
etcnscdconf is the configuration file used by the Name Service Cache Daemon (nscd) on many Unix-like systems. The file governs how the daemon caches results of Name Service Switch (NSS) lookups, such as user accounts, groups, host names, and network services, to speed up repeated queries. By controlling caching behavior, etcnscdconf helps reduce load on external sources like files, LDAP, or DNS while improving system performance.
Location and purpose: The file is typically /etc/nscd.conf. nscd reads this file at startup and when signaled
Configuration options: The file uses per-database directives to enable or disable caching and to set time-to-live
Examples: enable-cache passwd yes; enable-cache hosts yes; positive-time-to-live passwd 600; negative-time-to-live passwd 20; suggested-size passwd 1000.
Notes: Changes affect all users and processes. In environments using alternative services (sssd, unscd), nscd may
