NoIP Dynamic Update Client on RaspberryPi (or Ubuntu)

Personally I like to use NoIP’s dynamic DNS services. This tutorial explains how to install the NoIP DUC on a RaspberryPi running a Raspbian based distribution, but it will work on Ubuntu or any other Debian based distribution as well. You should execute all of the commands below as superuser. As not to have to put sudo in front of all of them, it’s best to log in as root or switch to root with sudo su.

Step 1: Install prerequisites

You will need some software to install and run the DUC software. Execute the following commands:

apt-get update
apt-get install build-essential python-setuptools
easy_install killproc

Step 2: Download and install the DUC software

Next you will have to download and install the DUC software itself. The software has to be built from source code, which is why we installed build-essential. The following commands will download and install the software:

cd /usr/local/src/
rm -r noip-*
wget http://www.no-ip.com/client/linux/noip-duc-linux.tar.gz
tar xf noip-duc-linux.tar.gz
rm noip-duc-linux.tar.gz
cd noip-*
make install

The commands above will first remove any previous source downloads for NoIP you might have had. Next it downloads the sources for the software and installs it. After installing it should immediately start the configuration wizard, which you can always restart using the command “/usr/local/bin/noip2 -C“. The configuration wizard will ask for your NoIP account details, as well as the host you want to be using. This should be mostly straight-forward. When it asks if you want to run anything on an update, you should probably just enter “No”.

Step 3: Running the DUC software on startup

By default, the DUC software will not start when you reboot your system. This is where killproc comes in, which we installed earlier. What we have to do now is set up an init script. We’re going to be using a simple script, as is described in the software’s readme file, with a slight alteration to make it work on our distribution. I have the script uploaded on my webserver, so you can just download it to your drive. Execute the following commands to install it and set it up:

cd /etc/init.d
wget http://ibeblog.com/files/noip2
chmod +x noip2
update-rc.d noip2 defaults

Step 4: Reboot

You’re all done now, so you can reboot the system now and when it boots up, the NoIP DUC software should be running.

Check available diskspace on Ubuntu (CLI)

If you are running an Ubuntu (or other linux) commandline interface, you might have to check how much diskspace is available on the system. You can easily have the system output a list of the disk space usage on all mounted filesystems with the command df -h.

The output depends completely on how your system is set up, but it will look something like:

Installing “pecl intl” (Ubuntu 12.04)

Some PHP software, such as MediaWiki, prefer for servers to have the “intl” PECL package to be installed. On Ubuntu you can insall it as a precompiled package from the official repositories:

If you start from a clean Ubuntu install and you want to build the package yourself, you might not have all of the dependencies installed. Run this command to make sure you have all of the prerequisites installed:

To build the package itself:

You might also have to restart your webserver if you manually build the package. For Apache, run:
