DNS client configuration steps in Oracle Solaris 11

This guide covers Quick how to configure DNS client on Solaris 11. 

DNS client configuration in Solaris 11 is based on SMF service rather than file based. When you configure a system as DNS client, you will be performing the following two configurations.
I. DNS client setup
II. Configure Name service switch to use DNS
I. DNS client setup
1. Configure using SMF service network/dns/client
# svccfg -s network/dns/client
svc:/network/dns/client> setprop config/search = astring: ("test.com" "service.test.com")
svc:/network/dns/client> setprop config/nameserver = net_address: (192.168.10.10 192.168.10.11)
svc:/network/dns/client> exit
2.  Enable the DNS client service (when you configure it for the first time)
#svccfg enable -r dns/client
3. Restart/Refresh DNS client service (It is done when there is any update to the configuration)
#svcadm refresh dns/client
#svcadm restart dns/client
4. Verify /etc/resolv.conf if it is updated with the changes.
# more /etc/resolv.conf

search               test.com service.test.com
nameserver      192.168.10.10
nameserver      192.168.10.11

II.  Configuring Name service switch to use DNS
1. Configure using SMF service  system/name-service/switch
# svccfg -s system/name-service/switch
svc:/system/name-service/switch> setprop config/host = astring: "files dns"
svc:/system/name-service/switch>exit
2.  Restart/Refresh name-service/switch service 
#svcadm refresh name-service/switch
#svcadm restart  name-service/switch
3. Verfiy host entry in /etc/nsswitch.conf  is updated with dns.
# more /etc/nsswitch.conf

#
# _AUTOGENERATED_FROM_SMF_V1_
#
# WARNING: THIS FILE GENERATED FROM SMF DATA.
#   DO NOT EDIT THIS FILE.  EDITS WILL BE LOST.
# See nsswitch.conf(4) for details.

passwd: files

Open a CLI session (serial or telnet for an unsecured system and sectelnet for a secure system) to the switch. 2. Log in as root. 3. At the prompt, enter the passwddefault command as shown below: switch:root> passwddefault 4. Follow the prompts to reset the password for the selected account.
