Dynamic DNS Setup In Ubuntu Using DynDNS

I use for dynamic domain services. There is easy setup and you can update your IP via a web browser, or schedule an application to run on a regular basis. Updating your IP address is important because you will lose your domain if you don’t update your record every 30-35 days. Here is a basic guide.

In Debian/Ubuntu you can install the updater via apt:

sudo apt-get install ipcheck

Create bin directory, dyndns directory and updater script:

mkdir ~/bin
mkdir ~/.dyndns
touch ~/bin/
chmod 700 ~/bin/
vi ~/bin/



cd ~/.dyndns
if [ -f ~/.dyndns/ipcheck.dat ]; then
/usr/sbin/ipcheck -r \
/usr/sbin/ipcheck --makedat -r \

Edit your crontab:

crontab -e

Add the following line to your crontab to run the script daily.

* 6 * * * /home/username/bin/

User Driven Sites

Today was completely spammed by user submitted articles about the HD-DVD media access key. Digg admins rightly decided to censor and ban users posting the number to avoid legal consequences. I only hope that the community driven site I am making doesn’t suffer from similar problems.
