How to configure DNS client

You can use below procedure to configure host as DNS client. In this example you already have DNS server

1. Modify your /etc/nsswitch.conf file to include DNS. For instance, you can copy from /etc/nsswitch.dns
   root@solaris-sunray # cp /etc/nsswitch.dns /etc/nsswitch.conf
2. Modify your /etc/resolv.conf to include IP address of your DNS server. In this example, your DNS server IP address is 172.16.20.249
   root@solaris-sunray # vi /etc/resolv.conf

     nameserver 172.16.20.249

     domain sun.com

     search sun.com

3. Make sure that your DNS client service is running.
   root@solaris-sunray # svcadm enable svc:/network/dns/client:default
4. Set your client domain name.
   root@solaris-sunray # vi /etc/defaultdomain

     sun.com

     # domainname sun.com

5. Test your DNS client configuration. Look IP address of server pool.ntp.org
   root@solaris-sunray # nslookup pool.ntp.org
   Server: 172.16.20.249
   Address: 172.16.20.249#53
