named.star(4) Kernel Interfaces Manual named.star(4)
NAME
named.star - Defines data used by named to initialize the BIND (Berkeley Internet Name Domain) name server file
SYNOPSIS
/etc/namedb/named.*
DESCRIPTION
The data files referenced in the named.conf file can have any names, but they are generally given names of the form /etc/namedb/named.*.
This naming convention is used for convenience in maintaining the named daemon's file.
The records in the named data files are called resource records. Except for comments (starting with a ; (semicolon) and continuing to the
end of the line), the resource records in the data files generally follow the format of the resource records that the named daemon returns
in response to queries from resolver routines.
The named.conf file is the default configuration (or boot) file for the named server. The named daemon reads the start-up file when the
named daemon starts and when receiving the signal SIGHUP.
EXAMPLES
The following examples portray two domains on two different networks: Domain abc.aus.osf.com, Internet address 192.9.201.n
(where n varies for each system on the network)
Domain xyz.aus.osf.com, Internet address 128.114.100.n
(where n varies for each system on the network)
In this sample configuration, both the primary and the secondary name servers are in the abc.aus.osf.com domain, and host hera is
the gateway host. The following are sample entries in a named.ca file: ; root name servers.
1 IN NS relay.osf.com. relay.osf.com. 3600000 IN A 129.114.1.2 The following two files are sam-
ple entries from the named.data files for hosts venus and allen. (The data files can have any name you choose, as long as that name
is defined in the named.boot file. In this case, the names are named.abcdata and named.xyzdata.)
