NSCD(8)                             Linux Programmer's Manual                             NSCD(8)



NAME
       /usr/sbin/nscd - name service cache daemon

DESCRIPTION
       Nscd  is  a  daemon  that  provides a cache for the most common name service requests. The
       default configuration file, /etc/nscd.conf, determines the behavior of the  cache  daemon.
       See nscd.conf(5).

       Nscd  provides  cacheing for the passwd(5), group(5), and hosts(5) databases through stan-
       dard libc interfaces, such as getpwnam(3), getpwuid(3), getgrnam(3), getgrgid(3), gethost-
       byname(3),  and others. Each cache has a separate TTL (time-to-live) for its data; modify-
       ing the local database (/etc/passwd, and so forth) causes the cache to become  invalidated
       within fifteen seconds. Note that the shadow file is specifically not cached.  getspnam(3)
       calls remain uncached as a result.


OPTIONS
       --help will give you a list with all options and what they do.


NOTES
       Nscd doesn't know anything about the underlaying protocols for a service. This also means,
       that if you change /etc/resolv.conf for DNS queries, nscd will continue to use the old one
       if you have configured /etc/nsswitch.conf to use DNS for host lookups. In such a case, you
       need to restart nscd.
