Configuring ddclient on Ubuntu Server to work with Dynu.com

I use dynu.com for determining my public IP address, I use a public IP address for Plex among many other things. dynu.com offers a completely free service, with no requirements to log in every 30 days, so this suits my needs perfectly.

Originally I installed an DDNS update client on my Windows box, but it suffers from flaky RAM and BSOD, so I decided to install the service on my Plex Media Server. It was a simple enough task, but I figured I should write down the step in case it can help anyone else.

Fist, install ddclient on your Ubuntu box:

sudo apt-get install ddclient

Then configure the ddclient:

sudo nano /etc/ddclient.conf

The contents should be similar to the following, using your username, password, domain name obviously:

# Configuration file for ddclient generated by debconf
#
# /etc/ddclient.conf
protocol=dyndns2
use=web, web=checkip.dynu.com/, web-skip='IP Address'
server=api.dynu.com
login=username
password='password'
domain.dynu.com

You can also determine the update interval by specifying the following in ddclient.conf:

# check every 60 seconds
daemon=60

Hope this is of some use for you. Thanks for reading.
