NAME
named.star - Defines data used by named to initialize the BIND (Berkeley
Internet Name Domain) name server file
SYNOPSIS
/etc/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/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
1. 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.
2. 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
3. The following two files are sample 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.)
The named file for host venus is in the following file, called
named.abcdata:
;OWNER TTL CLASS TYPE RDATA
;local domain server is venus
@ IN SOA venus bob.robert.abc.aus.osf.com. (
1.1 ;serial

IN HINFO HP-800 OS1
robert.abc.aus.osf.com. IN MX 10 venus.abc.aus.osf.com.
The named file for host allen is in the following file, called
named.xyzdata:
;OWNER TTL CLASS TYPE RDATA
;local domain server is venus
xyz.aus.osf.com. IN SOA venus.abc.aus.osf.com. bob.robe
rt.abc.aus.osf.com. (

; address for local loopback

; address of machines in the same domain
allen IN A 128.114.100.3

4. The following is a sample named.local file that might appear on hosts
in either of the sample domains:
@ IN SOA venus.abc.aus.osf.com. gail.zeus.abc.aus.osf.com.
(
1.1 ;serial
3600 ;refresh
600 ;retry
3600000 ;expire
86400) ;minimum
IN NS venus.abc.aus.osf.com.
1 IN PTR localhost.
5. The following two files are sample entries from the named.rev files
for hosts venus and allen. For this example, the files are called
named.abcrev and named.xyzrev.
The reverse file for host venus is in the following file, called
named.abcrev:
@ IN SOA venus.abc.aus.osf.com. bob.robert.abc.aus.osf.com.
(
1.1 ;serial
3600 ;refresh
600 ;retry
3600000 ;expire
86400) ;minimum
9.201.192.in-addr.arpa. IN NS venus.abc.aus.osf.com.
IN NS kronos.abc.aus.osf.com.
IN PTR hera.abc.aus.osf.com.
;ABC.AUS.OSF.COM Hosts
1.201.9.192.in-addr.arpa. IN PTR venus.abc.aus.osf.com.

7.201.9.192.in-addr.arpa. IN PTR ernie.abc.aus.osf.com.
The reverse file for host allen is in the following file, called
named.xyzrev:
@ IN SOA venus.abc.aus.osf.com. bob.robert.abc.aus.osf.com.
(
1.1 ;serial
3600 ;refresh
600 ;retry
