domainname(1M) System Administration Commands domainname(1M)
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 domainname 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
specified through the sendmail_vars entry in the /etc/nsswitch.conf
file, or through the /etc/mail/sendmail.cf file. Only the superuser can
set the name of the domain by specifying the new domainname as an argu-
ment. The domain name of the machine is usually set during 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.
