# mydnsimport(8)

Import zone data from external sources.

## NAME

mydnsimport - Import zone data from external sources.

## SYNOPSIS

**mydnsimport** \[**-a**, **--axfr=***host*\] \[**-D**, **--database=***dbname*\] \[**-h**, **--host=***hostname*\] \[**-o**, **--output**\] \[**-p**, **--password\[=***password*\]\] \[**-r**, **--replace**\] \[**-t**, **--tinydns=***file*\] \[**--notrim**\] \[**-u**, **--user=***username*\] \[**-v**, **--verbose**\] \[**--help**\] \[**--version**\] **ZONE** \[**...**\]

## DESCRIPTION

**mydnsimport** imports zone data into MyDNS from an external source. If an import technique is specified (for example, via the **--axfr** option), the specified zone data will be loaded and **mydnsimport** will add the zone data to your database. Currently, **--axfr** and **--tinydns** are the only import techniques recognized.

## OPTIONS

- **-a**, **--axfr**=*hostname\[:port\]*

  Load *zone* information from the specified *hostname* via the DNS-based AXFR command.

- **-o**, **--output**

  If this option is specified, **mydnsimport** outputs zone data in a computer-friendly format instead of modifying the database.  Each line of output consists of a *line type* (**soa**, **rr**, or **ptr**) followed by multiple fields.  Fields within each line are separated by the *TAB* (ASCII 0x09) character.  See **LINE SYNTAX**, below.

- **-r**, **--replace**

  When importing, if the *zone* specified already exists, **mydnsimport** will refuse to make changes to the database unless this flag is provided. When this flag is provided, if the *zone* already exists, its SOA record will be updated (from the external source), all resource records for that zone are purged, and a new set of resource records is loaded from the external source.

- **--notrim**

  Normally the zone origin is removed from labels when importing, in order to save space in the database.  In other words, **host.example.com. becomes** **just host.  Using the --notrim option inhibits this behavior.**

- **-D**, **--database**=*dbname*

  **Use the database called** *dbname***.**

- **-h**, **--host**=*hostname*

  **Connect to database server at** *hostname***.**

- **-p**, **--pass**=*password*

  **Supply** *password* **when connecting to the database server.  If** **the** *password* **argument is omitted, it will be prompted on the tty.**

- **-t**, **--tinydns**=*file*

  **Load** *zone* **information from the specified** *file***, which is in** **tinydns-data format.  When importing from a tinydns data file,** *zone* **may be omitted from the command line, in which case all zones found in** **the file are imported.**

- **-u**, **--user**=*username*

  **Use** *username* **when connecting to the database server.**

- **-v**, **--verbose**

  **Enable verbose output while running.**

- **--help**

  **Display program help and exit.**

- **--version**

  **Output version number and exit.**

## LINE SYNTAX

**When started with the -o (--output) option, mydnsimport** **outputs lines in the following format:**

- SOA

  **"soa" \<TAB\> origin \<TAB\> ns \<TAB\> mbox \<TAB\> serial \<TAB\> refresh \<TAB\> retry \<TAB\> expire \<TAB\> minimum \<TAB\> ttl**

- RR

  **"rr" \<TAB\> name \<TAB\> type \<TAB\> data \<TAB\> aux \<TAB\> ttl**

- PTR

  **"ptr" \<TAB\> address \<TAB\> name \<TAB\> ttl**
