NAME

  domainname - display or set the name of the current NIS domain for this
  system

SYNOPSIS

  domainname [nameofdomain]

DESCRIPTION

  The domainname command, when used without an argument, displays the name of
  the current domain. When used	with argument, sets the	current	Network
  Information Service (NIS) domain name	to the specified domain	name.

  A domain is a	logical	grouping of networked-connected	systems	established
  for the purpose of sharing a common set of NIS data files. Domains are only
  used by NIS.

  The NIS maps for a particular	domain are stored in the directory
  /var/yp/domainname on	each NIS server.  Each NIS  map	contains a set of
  keys and associated key values. For example, in a map	called hosts.byname,
  the host names stored	there constitute the keys. The corresponding internet
  addresses of each host constitute the	associated key values.
