domainname(1)

domainname1

Set or print name of current yp/nis domain

Usage

domainname [ypdomain]

Overview

The domainname utility prints the name of the current YP/NIS domain. The super-user can set the domain name by supplying an argument; this is usually done with the nisdomainname variable in the /etc/rc.conf file, normally runs at boot time.

Notes

The YP/NIS (formerly ``Yellow Pages'' but renamed for legal reasons) domain name does not necessarily have anything to do with the Domain Name System domain name, although they are often set equal for administrative convenience.
