nscd(1M) System Administration Commands nscd(1M)
NAME
nscd - name service cache daemon
SYNOPSIS
/usr/sbin/nscd [-f configuration-file] [-g] [-e cachename, yes | no] [-i cachename]
DESCRIPTION
nscd is a process 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(4).
nscd provides caching for the passwd(4), group(4), hosts(4), ipnodes(4), exec_attr(4), prof_attr(4), and user_attr(4) databases through
standard libc interfaces, such as gethostbyname(3NSL), getipnodebyname(3SOCKET), gethostbyaddr(3NSL), and others. Each cache has a separate
time-to-live for its data; modifying the local database (/etc/hosts, /etc/resolv.conf, and so forth) causes that cache to become invali-
dated upon the next call to nscd. The shadow file is specifically not cached. getspnam(3C) calls remain uncached as a result.
nscd also acts as its own administration tool. If an instance of nscd is already running, commands are passed to the running version trans-
parently.
In order to preserve NIS+ security, the nscd service checks the permissions on the passwd table if NIS+ is being used. If this table cannot
be read by unauthenticated users, then nscd will make sure that any encrypted password information returned from the NIS+ server is sup-
plied only to the owner of that password.
OPTIONS
Several of the options described below require a cachename specification. Supported values are passwd, group, hosts, ipnodes, exec_attr,
prof_attr, and user_attr.
-f configuration-file Causes nscd to read its configuration data from the specified file.
-g Prints current configuration and statistics to standard output. This is the only option executable by non-root
users.
-e cachename, yes|no Enables or disables the specified cache.
-i cachename Invalidate the specified cache.
EXAMPLES
Example 1: Stopping and restarting the nscd daemon.
example# svcadm disable system/name-service-cache
example# svcadm enable system/name-service-cache
FILES
/etc/nscd.conf Determines athe behavior of the cache daemon

NOTES
The output from the -g option to nscd is subject to change. Do not rely upon it as a programming interface.
The nscd service is managed by the service management facility, smf(5), under the service identifier:
svc:/system/name-service-cache
Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed using svcadm(1M). The ser-
vice's status can be queried using the svcs(1) command.
