 1 | # Yandex dDNS updater
 2 | ### Dynamic DNS client for pdd.yandex.ru (Linux & OS X)
 3 | [По-русски / In Russian](README.ru.md)
 4 | 
 5 | A very basic shell script updater for dynamic DNS services provided by <http://pdd.yandex.ru>. 
 6 | 
 7 | ## Instructions:
 8 | 
 9 |  1. Get **token** at [Token management](https://pddimp.yandex.ru/token/index.xml) page. See [Yandex API manual](http://api.yandex.ru/pdd/doc/reference/api-dns_get_token.xml) for details.
10 |  2. Edit **ya.ddns.update.sh** in a text editor, and modify the *hostname*, and *token* fields.
11 |  3. If desired, set `$use_ifconfig='yes'` and `$iface='eth0'`. Otherwise, the script will use http://checkip.dns.he.net to determine your public IP address.
12 |  4. If necessary, `chmod +x ya.ddns.update.sh`.
13 |  5. Run **ya.ddns.update.sh**.
14 |  6. Use system's cron to schedule the updates. Or LaunchDaemon. Whatever floats your boat.
15 | 
16 | ### Notes
17 |  * Works both for primary domain (*example.com*) and subdomains (*foo.example.com*, *foo.bar.example.com*).
18 |  * DNS "A" record for *hostname* must exist before you run this script.
19 |  * **yapdate.sh** is a simplier script, but won't work behind router.
20 | 
21 | **License**: [WTFPL](http://www.wtfpl.net) or [MIT](http://opensource.org/licenses/MIT).<br />**Warranty**: None.
22 | 
23 | Enjoy!

 1 | # Yandex dDNS updater
 2 | ### Dynamic DNS клиент для pdd.ya.ru (Linux & OS X)
 3 | [In Russian / По-английски](README.md)
 4 | 
 5 | Простой шелл-скрипт обновления DNS в сервисе <http://pdd.yandex.ru>.
 6 | 
 7 | ## Инструкция:
 8 | 
 9 |  1. Получите **token** на странице [Token management](https://pddimp.yandex.ru/token/index.xml). Подробности в [руководстве Yandex API](http://api.yandex.ru/pdd/doc/reference/api-dns_get_token.xml).
10 |  2. Откройте **ya.ddns.update.sh** в любом текстовом редакторе, установите *hostname* и *token*.
11 |  3. Можете установить `$use_ifconfig='yes'` и `$iface='eth0'`. Иначе скрипт будет получать внешний IP адрес при помощи сервиса http://checkip.dns.he.net.
12 |  4. Чтобы сделать файл исполняемым, выполните `chmod +x ya.ddns.update.sh` (если нужно).
13 |  5. Запустите **ya.ddns.update.sh**.
14 |  6. Используйте cron для запуска по расписанию. Или LaunchDaemon. Ну или что там у вас.
15 | 
16 | ### Замечания
17 |  * Работает как с основным доменом (*example.com*), так и с субдоменами (*foo.example.com*, *foo.bar.example.com*).
18 |  * "A"-запись в DNS для *hostname* нужно создать до запуска скрипта.
19 |  * **yapdate.sh** более простой скрипт, но не работает, если вы за роутером.
20 | 
21 | **Лицензия**: [WTFPL](http://www.wtfpl.net) или [MIT](http://opensource.org/licenses/MIT).<br />**Гарантия**: Никакой.
22 | 
23 | Используйте с удовольствием!
