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

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. SunOS 5.10 30 Oct 2003 nscd(1M)
