       domain for this system

SYNOPSIS    [Toc]    [Back]

       domainname [nameofdomain]

DESCRIPTION    [Toc]    [Back]

       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.
