Define Elements of the Name Server Configuration File
The name server configuration file (/etc/named.boot) is a simple text file in which comment lines are indicated with a semicolon (;). Each line of the file addresses some aspect of name server configuration. The lines have the following format:
The code below is a typical example of an /etc/named.boot file.
Earlier, we pointed out that an @ sign in a zone file is replaced by the server with the appropriate zone. The information to replace the @ sign comes from the named.boot file.
Notice that no special configuration is necessary to create a caching-only server. Simply specify no primary or secondary zones (except loopback), and you will get a caching server.
