domainname(1)

NAME

domainname − set or display name of Network Information Service domain

SYNOPSIS

domainname [name_of_domain]

DESCRIPTION

Network Information Service (NIS) uses domain names to refer collectively 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 configuration file /etc/rc.config.d/namesvrs, by setting the NIS_DOMAIN variable.

DEPENDENCIES

NIS servers use the NIS domain name as the name of a subdirectory of /var/yp. 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 version 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.
