Open Source

Use of open source technology

Whilst Extility is not itself an open source product, it utilizes a number of open source components. We have also contributed to several open source projects, and have open sourced a number of our tools and utilities.

You can find links to specific open source contributions we have made using the menu bar on the left.

Roll of honour

Below we list a few of the open source components we are proud to say we use below:

	The Linux Kernel
	Ubuntu 10.04 LTS (Lucid)
	KVM
	Xen
	Curl
	OpenSSH
	Bird

 

Obtaining the source code for open source components.

Extility is based on Ubuntu 10.04 Lucid, and unless otherwise indicated per the menu to the left, the source of all open source components is available through Ubuntu’s source repository. On an Extility install, simply type:

$ apt-get source packagename

to retrieve the source.

Extility contains no modifications to open source components which operate under “copy left” licences (i.e. ones requiring publication of the source code of modifications) save where such modifications have been contributed upstream to the project itself and/or to Ubuntu. It is Flexiant’s business practice, however, to publish all modifications to open source components, whether required by the licence or not. The pages linked from the menu bar to the left reflect this.
