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.
