DESCRIPTION

hosts_to_named

translates the host table, /etc/hosts, into ﬁles that are usable by the name

server,

named (see named(1M)). The format of these ﬁles is deﬁned in RFC 1035. The ﬁles are created

in the current directory. Once the host table is translated, the name server ﬁles can be maintained

directly, or the translation can be repeated after each change to the host table.

If a line in the host table contains no domain names, all names on the line are assumed to be in the

default domain. The ﬁrst domain listed is the default domain. If data is being created for more than one

domain or if certain options are used, there must be domain names in the host table to determine which

names belong in which domain.

The name server data is referred to as resource records .

Options

hosts_to_named has the following options:

-a network-number

Add the information about hosts in the local domain from network network-number. This is

the same as the

-n option except that no pointer (PTR) data is created. This is useful when

there are multiple domains on a network and a different server is handling the address-to-

name mapping for network-number.

-A Do not create name server data for aliases in the host table.

-ARPA Create IP6.ARPA reverse lookup domain instead of IP6.INT. The pointer (PTR) records are

placed in the ﬁle, db.IP6.ARPA.

-b bootfile

Name the boot ﬁle bootﬁle. The default is named.boot (if named is version 4.x) or

named.conf (if named is version 8.x or 9.x) in the current directory.

-c subdomain

Create alias (CNAME) records for hosts in subdomain of the default domain. When a sub-

domain is delegated, it is useful to create aliases for the old names in the default domain that

point to the new names in the subdomain . After creating the alias (CNAME) records, ignore

lines in the host table that contain names in the subdomain . This option can be used more

than once on the command line. This option requires domain names in the host table. When

the old names in this domain are no longer used, they can be ignored with the -e option. If

the subdomain name does not have dots, the default domain is appended to subdomain .

-C file Create resource records from strings in the comment ﬁeld of the host table. Each string in the

comment ﬁeld (except [no smtp]) is searched for in ﬁle . The format of each line of ﬁle is a

string, a colon, and a resource record. If the string in the comment ﬁeld matches a string

before a colon in ﬁle, a resource record is added consisting of the name of the host followed by

everything after the colon from the matching line in ﬁle . For example, host information

(HINFO) records can be created by adding

360:IN HINFO hp9000s360 hp-ux

to ﬁle and adding 360 to comments in the host table.

-d domain

Create data for domain . This option can be used more than once on the command line if data

is being created for more than one domain. The ﬁrst domain listed is the "default domain".

This option requires domain names in the host table for all hosts in domains except the default

domain.

PAGE 2
hosts_to_named(1M) hosts_to_named(1M) (BIND 9.3) -D Do not create name server data for domain names in the host table. -e subdomain Eliminate lines from the host table that contain names in the subdomain before translating. If the subdomain name does not have dots, the default domain is appended. This option may be used more than once on the command line. This option requires domain names in the host table. -f file Read command-line options from file . The -f option is not allowed within a file.
PAGE 3
hosts_to_named(1M) hosts_to_named(1M) (BIND 9.3) Note: At least one name server (either default or explicitly declared using the -s option) will be included in all the database files, in addition to those declared using the -S option. -t Create text (TXT) records from the comments that appear with host data. The comments will all be in lower case because the host table is translated to lower case. If [no smtp] appears in a comment, it is omitted.
PAGE 4
hosts_to_named(1M) hosts_to_named(1M) (BIND 9.3) Pointer (PTR) records are created for mapping IPv6 addresses to host names. The IPv6 PTR records are placed in db.IP6.ARPA, if the -ARPA option is specified; otherwise, they are placed in db.IP6.INT. Mail exchanger (MX) records are created unless the -M option is used. The default MX record has a weight of 10 with the host itself as its mail exchanger.
PAGE 5
hosts_to_named(1M) hosts_to_named(1M) (BIND 9.3) 5. Create name server data for multiple domains div1.inc.com, div2.inc.com and div3.inc.com. You must declare 15.18.1.1 as the host in the start-of-authority (SOA) record for all the domains. Also, create a secondary boot file from the primary boot file listing 15.18.1.1 and 15.18.2.1 as the servers to load the data from, to all the domains. Declare 15.18.2.1 as an authoritative name server for the domain div2.inc.com in addition to the default server.
