7.3.1. How Do I Do That?
Fedora provides the named domain name server, which is the Berkeley Internet Name Domain (BIND). named serves two roles:
authoritative nameserver
Serves name information about one or more domains to other servers.
caching nameserver
Provides name lookups for client programs such as web browsers by contacting other nameservers. This information is cached in local storage in case it is requested again in the near future.
The Fedora package called bind contains the named service.
The named service is not run by default. Once you configure it to run (see Lab 4.6, "Managing and Configuring Services "), it will act as a caching nameserver:
If you just want to use named as a caching nameserver, you can skip to the section entitled "Using your nameservers locally."
To configure named as an authoritative nameserver for your domain, you just have to give it the information about your domain that you want it to serve to other systems. Usually at least two authoritative nameservers are set up for each domain; one is configured as the master , and the others are slaves . Changes to the DNS data are made on the master, and the slaves update themselves periodically.
You can configure an authoritative nameserver graphically or by editing configuration files and datafiles.
