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 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 by setting the variable. The name_of_domain is normally 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 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.
