5.16. /var/yp : Network Information Service (NIS) database files (optional)

5.16.1. Purpose

Variable data for the Network Information Service (NIS), formerly known as the Sun Yellow Pages (YP), must be placed in this directory.


/var/yp is the standard directory for NIS (YP) data and is almost exclusively used in NIS documentation and systems. [47]

[47] NIS should not be confused with Sun NIS+, which uses a different directory, /var/nis.
