DOMAINNAME(1)                                                    DOMAINNAME(1)



NAME
     domainname - set or display name of current NIS domain

SYNOPSIS
     domainname [ name-of-domain ]

DESCRIPTION
     Without an argument, domainname displays the name of the current network
     information service (NIS) domain, which typically encompasses a group of
     hosts under the same administration.  As such, the name of an NIS domain
     is typically a valid Internet domain name in order to be consistent with
     the domain name used by the BIND name server, named(1M).

     Only the super-user can set the domain name by giving an argument; this
     is performed by the system startup procedure using the contents of
     /var/yp/ypdomain.  This setting is persists only until the machine is
     rebooted, when it will once again be set using the contents of the above
     file.  To permanently change the value change this file, then run the
     domainname command as a privileged user or run the command:
     /var/yp/ypinit -c.

     Currently, the network information service uses domains only to refer
     collectively to a group of hosts.
