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. For this,

name_of_domain should not be a

. or .. and it should 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 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.
