nis, NIS, NIS+ - network information name service
NIS, formerly known as the Yellow Pages or YP, is the name of the network information name service originally developed by Sun Microsystems. The most recent version of NIS is version 2. NIS was commonly used with SunOS, Solaris, and other UNIX workstations, but has been supplanted in recent years by the LDAP name service. All components of NIS, including clients, servers, tools, and programming interfaces might not be available in a future update of Oracle Solaris. NIS users should migrate to the LDAP naming service.
All commands and functions that use NIS version 2 are prefixed by the letters yp as in ypmatch(1), ypcat(1), yp_match(3C), and yp_first(3C).
The NIS+ name service is no longer shipped with the Oracle Solaris operating system. Tools to aid the migration from NIS+ to LDAP are available in the current Solaris release.
