Dynamic DNS updater

From NAS-Central Buffalo - The Linkstation Wiki

Installing a Dyndns updater

Sites like www.dyndns.org allow you to use names like mysite.homelinux.com mysite.dyndns.org instead of your IP address, even if your IP address changes all the time as is often the case with DSL connections.

• Get an account at www.dyndns.org Write down your dyndns.org username and password, you’ll need it for the dyndns updater configuration. Just for simplicity, let’s assume you created “MyOwnDyndnsAccount” with a “MyOwnDyndnsPassword” password.

• Create a Dynamic DNS entries at dyndns.org.

example: 3 names
mysite1.homelinux.com
mysite2.homelinux.com
mysite3.homelinux.com

• Get on your Linkstation using telnet or ssh apt-get install ddclient

apt-get install ddclient

• You’ll get a few questions from the installer (don't remember the exact order):
  • The interface: "web".
  • username:"MyOwnDyndnsAccount"
  • password:"MyOwnDyndnsPassword"
  • Dyndns hosts list: use commas “,” between the Dyndns host names: mysite1.homelinux.com,mysite2.homelinux.com,mysite3.homelinux.com"

• If you wish to modify the file directly, here’s a sample that works:

Linkstation:/etc# more ddclient.conf
pid=/var/run/ddclient.pid
protocol=dyndns2
use=web
server=members.dyndns.org
login=MyOwnDyndnsAccount
password=MyOwnDyndnsPassword
mysite1.homelinux.com,mysite2.homelinux.com,mysite3.homelinux.com
