DNS updater shell script for Linux & OS X

По-русски / In Russian

A very basic shell script updater for dynamic DNS services provided by http://pdd.yandex.ru.

Instructions:

1. Get token at Token management page. See Yandex API manual for details.
2. Edit ya.ddns.update.sh in a text editor, and modify the hostname, and token fields.
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.
4. If necessary, chmod +x ya.ddns.update.sh.
5. Run ya.ddns.update.sh.
6. Use system's cron to schedule the updates. Or LaunchDaemon. Whatever floats your boat.

Notes

• Works both for primary domain (example.com) and subdomains (foo.example.com, foo.bar.example.com).
• DNS "A" record for hostname must exist before you run this script.
• yapdate.sh is a simplier script, but won't work behind router.
