domainname - Set or display name of the current domain


     domainname [name-of-domain]


     Without an argument, domainname displays  the  name  of  the
     current domain, which typically encompasses a group of hosts
     or passwd entries under the same administration.The  domain-
     name  command  is  used  by various components of Solaris to
     resolve names for types such as passwd, hosts  and  aliases.
     By  default,  various naming services such as NIS, NIS+, the
     Internet Domain Name Service (DNS) and sendmail(1M) use this
     domainname  to  resolve  names. The domainname is normally a
     valid Internet domain name.

     The domainname for various naming services can also  be  set
     by  other means.  For example, ypinit can be used to specify
     a  different  domain  for   all   NIS   calls.    The   file
     /etc/resolv.conf  can  be used to specify a different domain
     for DNS lookups.  For sendmail, the domainname can be speci-
     fied    through    the    sendmail_vars    entry    in   the
     /etc/nsswitch.conf      file,      or      through       the
     /etc/mail/  file.  Only the superuser can set the
     name of the domain by specifying the new  domainname  as  an
     argument. The domain name of the machine is usually set dur-
     ing  boot-time  through  the  domainname  command   in   the
     /etc/init.d/inetinit  file.  If  the  new domain name is not
     saved in  the  /etc/defaultdomain  file,  the  machine  will
     revert back to the old domain after rebooting.
