hosts_to_named(1M)

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.

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

Create IP6.ARPA reverse lookup domain instead of IP6.INT. The pointer (PTR) records are placed in the file, db.IP6.ARPA.

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.

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

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.

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.

Do not create name server data for domain names in the host table.

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.

Read command-line options from file. The -f option is not allowed within a file.

Force the serial number to be incremented, even if the data has not changed. By default, the serial number is incremented for a domain only if the data has changed (pointer (PTR) data only).

Declare host to be the host in the start-of-authority (SOA) record that the name server data was created on. Also use host for the electronic mail address of the responsible user in the SOA record. The default is the host this command is run on. This option applies to all the domains generated by hosts_to_named. If this option is specified more than once, only the last value will be considered.

Use host-file instead of /etc/hosts.

For each canonical host name from the host table, create mail exchanger (MX) records with the specified weight and mail hub. The weight is a positive integer. The mail hub is a host name. If the mail hub name has no dots, the default domain is appended. This option can be used more than once on the command line.

Do not create mail exchanger (MX) records for hosts in the host table.

Create data for network-number. See the Operation subsection for the description of network-number. If only one domain is listed with the -d option, all data for network-number is assumed to be in domain. The optional subnet mask mask can be used instead of supplying each network-number for a subnet using multiple -n options. mask must be in dot notation. This option is not applicable for creating IPv6 addresses.

Apply the default subnet mask mask to each network-number specified with the -n option except for ones with their subnet masks already provided. mask must be in dot notation. This is the same as supplying each network-number for a subnet using multiple -n options.

Set the values in the start-of-authority (SOA) record to those specified. See the Operation subsection for the description of the start-of-authority (SOA) record.

Create only pointer (PTR) data for hosts in domain. This is useful when there are multiple domains on a network and a different server is responsible for domain, but this server is responsible for the address-to-name mapping. This option can be used more than once on the command line. This option requires domain names in the host table.

Run quietly. No messages are printed.

Create name server data indicating that the name server is authoritative for . (the root of the domain tree). The file created is db.root. Use this only when your network is isolated from the Internet. If other root servers exist for the isolated network, they must be added manually.

Create name server (NS) records that declare server is an authoritative name server for all of the domains created. If more than one server is authoritative, each needs to be declared. If the server name does not have any dots in it, the default domain is appended. If you do not specify the -s option, the default name server is the host on which you execute the script. You can use this option more than once on the command line to specify multiple name servers.

This option is the same as the -s option, but it only applies to the last domain specified with a -d option or the last network-number specified with a -n option. This option is for when server is backing up some, but not all, of the domains.

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.

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. The [no smtp] is used to control mail exchanger (MX) data.

Declare user to be the electronic mail address of the person responsible for this domain. This is used in the start-of-authority (SOA) record. The format required in the name server data is user.host ,RI ( host must be a domain name). If given as user (without .host), the host on which this script is run is appended. If given as user@host, the @ is replaced with a dot (.). The default user is root. This option applies to all the domains generated by hosts_to_named. If you specify this option more than once, only the last value will be used.

Create well-known services (WKS) data declaring that the host provides the SMTP service. This is done only when mail exchanger (MX) data is also being created and only for hosts without [no smtp] in a comment.

Create a secondary boot file, boot.sec.save (if named is version 4.x) or conf.sec.save (if named is version 8.x or 9.x), from the primary boot file, listing internet-address as the server to load the data from. The boot file has the server back up the data on disk. The internet-address defaults to the value used with -Z. You can specify this option more than once to declare multiple servers from which data can be loaded.

Note: All the servers declared using this option will be listed for all the domains.

Create a secondary boot file, boot.sec (if named is version 4.x) or conf.sec (if named is version 8.x or 9.x), from the primary boot file, listing internet-address as the server to load the data from. The boot file does not have the server back up the data on disk. The internet-address defaults to the value used with -z. You can use this option more than once to declare multiple servers from which data can be loaded.

Note: All the servers declared using this option will be listed for all domains.
