NAME
  named.boot - named configuration file

SYNOPSIS
  /etc/named.boot

DESCRIPTION
  This 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 signal SIGHUP.

  The records in the named.boot file tell the named daemon what type of
  server it is, which domains (or zones of authority) it has authority over,
  and where to get the data for initially setting up its database.

  The name server first needs to know the root name server, which is the
  authority server for the network. The root name server is established in
  the named.boot file by specifying the root server filename (named.ca) as
  the cache for this name server.

  The general format of each line in this file is as follows:


       Type Domain Source

  Type	    Determines the type of information required for the database.
	    The Type field can have one of the following values:

	    domain    Indicates that the following Domain entry is the name
		      of the default domain.  When the named daemon receives
		      a query with a domain or hostname that does not end
		      with a . (dot), the named daemon appends the default
		      domain name to the queried name.

	    primary   Indicates that the local named server is the primary
		      name server for the domain specified in the Domain
		      field and that the named daemon is to get the data
		      describing the domain from the file specified in the
		      Source field.

	    secondary Indicates that the local named server is a secondary
		      name server for the domain specified in the Domain
		      field and that the named daemon is to get the data
		      describing the domain from one or more remote primary
		      name servers using the Internet address or addresses
		      specified in the Source field.  The named daemon tries
		      each address in the order listed until it successfully
		      receives the data from one of the name servers.

	    cache     Indicates that the local named server is a caching name
		      server for the domain specified in the Domain field and
		      that the named daemon is to get the data describing the
		      domain from the file specified in the Source field.

	    See named(8) for additional named.boot file directives.

  Domain    Specifies the domain.

  Source    Specifies a file containing information that describes the
	    domain.

  Note that the named daemon does not provide other hosts with the
  information contained in a cache file. Cache files are usually used for
  listing the name servers for domains higher than the local domain.

  Comments in the boot file begin with a ; (semicolon) and end at the end of
  the line.

  These data files can have any name. However, for convenience in maintaining
  the named database, they are generally given names in the following form:
  /etc/named.extension.	 The general format of named data files is described
  in /etc/named.*.

EXAMPLES
  The following examples show the various ways to use the named start-up
  file.

   1.  The /etc/named.boot file for venus, a primary name server, contains
       these entries:
	    ; Boot file for primary name server
	    ;
	    ; type	  domain		  source file or host
	    domain	  abc.aus.osf.com
	    cache	  .			   /etc/named.ca
	    primary	  abc.aus.osf.com	    /etc/named.abcdata
	    primary	  xyz.aus.osf.com	    /etc/named.xyzdata
	    primary	  201.9.192.in-addr.arpa    /etc/named.abcrev
	    primary	  100.114.128.in-addr.arpa  /etc/named.xyzrev
	    primary	  0.0.127.in-addr.arpa	    /etc/named.local

       In this example, the primary name server is venus and the Internet
       address is 192.9.201.1.

   2.  The /etc/named.boot file for kronos, a secondary name server, contains
       these entries:
	    ; Boot file for secondary name server
	    ;
	    ; type	  domain		  source file or host
	    domain	  abc.aus.osf.com
	    cache	  .			  /etc/named.ca
	    secondary	  abc.aus.osf.com	   192.9.201.1 192.9.201.2
	    secondary	  xyz.aus.osf.com	   192.9.201.1 192.9.201.2
	    secondary	  201.9.192.in-addr.arpa   192.9.201.1 192.9.201.2
	    secondary	  100.114.128.in-addr.arpa 192.9.201.1 192.9.201.2
	    primary	  0.0.127.in-addr.arpa	   /etc/named.local

       In this example the secondary name server is kronos and the Internet
       address is 192.9.201.2.

   3.  The /etc/named.boot file for hera, a cache-only name server, contains
       these entries:
	    ; Boot file for cache only server
	    ;
	    ; type	  domain		  source file or host
	    domain	  abc.aus.osf.com
	    cache	  .			 /etc/named.ca
	    primary	  0.0.127.in-addr.arpa	  /etc/named.local
