NAME

       tinydns-edit - append entries to the DNS resource file

SYNOPSIS

       tinydns-edit data data.tmp add type name address

DESCRIPTION

       tinydns-edit edits the data file, which is the source form of the
       database that is compiled by tinydns-data and that is served by tinydns
       and axfrdns.  The update to data is performed atomically, by first
       writing the updated data content to the file data.tmp and then renaming
       data.tmp to data.  The two files must, of course, reside on the same
       volume in order to achieve this.

       IPv4 address is given in the standard decimal-dotted format, while IPv6
       address is expressed in their compactified format.

APPEND MODE

       tinydns-edit reads the provided data file with the resource records in
       their particular format and adds the given DNS settings to data.  On
       success, tinydns-edit returns zero. If the particular entry already
       exists, or an error occures, data will not be changed.

       However, for entries of given type like ns and mx tinydns-edit appends
       to the existing data file a new record with a syntheszied and
       automatically incremented hostname for the given name and address.

       After a customized installation of tinydns with tinydns-conf you may
       use add-alias, add-childns, add-host, add-host6, add-mx and add-ns to
       append those specfic DNS records to your existing data file.

       In order to transform data to data.cdb, which is required by tinydns
       and axfrdns, you need to compile it by means of tinydns-data.

DATA TYPES

       The record types generated by tinydns-edit are indidcated via a token
       in the first column.  type can be one of:

       ns     A '.' record is created.  This record specifies that the domain
              name is published by a DNS content server that is listening on
              the IPv4/IPv6 address.

              The name of the DNS content server is not directly specifiable.
              Names are automatically assigned by tinydns-edit itself,
              following the pattern [a-z].ns.name.  tinydns-edit will assign
              the first letter of the alphabet that is not already used in
              another '.' or '&' record as the name of a DNS content server.
              If no letters of the alphabet remain unused, tinydns-edit will
              fail.

              If a '.' or '&' record for the domain already exists, proxy DNS
              servers are allowed to cache the new record for the same length
              of time as they are allowed to cache the existing records.
              Otherwise, proxy DNS servers are allowed to cache the record for
              up to 3 days.
              If a '.' or '&' record for the domain already exists, proxy DNS
              servers are allowed to cache the new record for the same length
              of time as they are allowed to cache the existing records.
              Otherwise, proxy DNS servers are allowed to cache the record for
              up to 3 days.

       mx     A '@' record is created.  This record specifies that mail to
              names in the domain name should be sent to an SMTP server that
              is listening on the IPv4/IPv6 address.

              The name of the SMTP server is not directly specifiable.  Names
              are automatically assigned by tinydns-edit itself, following the
              pattern [a-z].mx.name.  tinydns-edit will assign the first
              letter of the alphabet that is not already used in another '@'
              record as the name of an SMTP server.  If no letters of the
              alphabet remain unused, tinydns-edit will fail.

              It is not possible to specify the distance value for the SMTP
              server.  tinydns-edit will leave that field blank, meaning that
              tinydns-data will use whatever the default value is.

              If a '@' record for the domain already exists, proxy DNS servers
              are allowed to cache the new record for the same length of time
              as they are allowed to cache the existing records.  Otherwise,
              proxy DNS servers are allowed to cache the record for up to 1
              day.

       host   A '=' record is created, that proxy DNS servers are allowed to
              cache for up to 1 day.  This record specifies that name maps to
              IPv4 address and vice versa.

       host6  A '~' record is created, that proxy DNS servers are allowed to
              cache for up to 1 day.  This record specifies that name maps to
              IPv6 address and vice versa.

              tinydns-edit will fail if a '=' or '~' record already exists
              that uses either the same name or address.

       alias  A '+' record is created, that proxy DNS servers are allowed to
              cache for up to 1 day.  This record specifies that name maps to
              IPv4 address but that there is no reverse mapping.

       alias6 A '-' record is created, that proxy DNS servers are allowed to
              cache for up to 1 day.  This record specifies that name maps to
              IPv6 address but that there is no reverse mapping.

              Because these are alias records, tinydns-edit will not fail for
              distinct '+' or '-' entries pointing to the same address.
