Configuring Domain Name System (DNS) servers

The DNS Manager interface

You can start the DNS Manager in any of these ways:

Start the SCOadmin launcher by entering scoadmin on the command line, then select Networking DNS Manager.
Enter scoadmin DNS Manager on the command line.

For more information on using SCOadmin managers, see ``Administering your system with SCOadmin''.

With the DNS Manager, you can:

Configure a host as a master, stub, and/or slave name server for one or more zones, or simply to act as a caching-only server.
Modify the configuration of a zone defined on a name server.
Control how the manager displays information about a zone on the master name server.
Set general preferences for the behavior of name service including use of forwarders, address sorting, ignoring bad servers, selecting networks and hosts that can request zone file transfers, limits, and options.
Control the DNS daemon process, named.
Define default resource records for zones that have not yet been configured on a master name server.

NOTE: The DNS Manager is intended for setting up zone files from new. It will read and preserve the contents of existing zone files in most cases but it does not understand the $include directive or types of resource record other than A, CNAME, HINFO, MX, NS, PTR, RP, and TXT.

You will not be able to use the DNS Manager to configure DNS on a remote host unless the remote host's name is locally resolvable to an IP address using an /etc/hosts entry, DNS, or NIS.
