NAME
       domainname - set or display name of Network Information Service domain

SYNOPSIS
       [name_of_domain]

DESCRIPTION
       Network	Information  Service  (NIS) uses domain names to refer collec‐
       tively to a group of hosts.  Without an argument,  domainname  displays
       the  name of the NIS domain.  Only superuser can set the domain name by
       providing name_of_domain.  The domain name is usually set in  the  con‐
       figuration  file	 by  setting the variable.  The name_of_domain is nor‐
       mally a valid Internet domain name.

DEPENDENCIES
       NIS servers use the NIS domain name as the name of  a  subdirectory  of
       Therefore,  name_of_domain cannot be a or and it must not contain Since
       the NIS domain name can be as long as 64 characters, name_of_domain may
       exceed the maximum file name length allowed on a given file system.  If
       that length is exceeded, the subdirectory name becomes a truncated ver‐
       sion of the NIS domain name.

       The  first  14  characters  of  all  NIS domains on the network must be
       unique; truncated names should be checked to verify that they meet this
       requirement.
