1 Configuring a DNS client and the name Service switch in Solaris : Tim WortThis paper examines two methods used to configure and modify the DNS client configuration on a Solaris 11 host. These methods work for release 11/11, and The DNS client SMF service contains a number of properties that are used to define the DNS client configuration, these properties are used by the service to generate the / file. Additionally the name Service SwitchSMF service defines properties that generates the / the svc:/network/dns/ client :default service has never been configured on the system you can copy a existing / file and run the following command:root@solaris:~# nscfg import dns/ client The command adds the properties values used to create the / to the svc:/network/dns/ client :default service.

2 The administrator then refreshes and restarts the service, or reboots the @solaris:~# svcadm refresh dns/clientroot@solaris:~# svcadm restart dns/clientSimilarly for the frst time configuration of the name Service switch service, copy a existing / file and run the following command:root@solaris:~# nscfg import name -service/switchThen refresh and restart the svc:/system/ name -service/ switch :default service, or the services have been configured they can be modified by making changes to the file or the file and use nscfg command with the -f option:root@solaris:~# nscfg import -f dns/clientroot@solaris:~# nscfg import name -service/switchThen refresh and restart the services or a DNS client and name Service switch manually in Solaris Solaris 11 the / is automatically populated by thedns/ client service and manual edits will be lost when thedns/ client service is started or set values for the / administrators must set properties in thedns/ client listing of the default / for a Solaris 11 instance:tim@solaris:~$ cat / ## Copyright (c) 2011, Oracle and/or its affiliates.
