The OTRS source code is published under the Affero General Public License (AGPL V.3) and therefore available for free download. It is hosted in a CVS repository that allows to keep track of all work and all changes made by several community-based developers who collaborate with the OTRS developers.
You need to have the appropriate tools to download the code from the repository. Once the tools are installed:
Login to the CVS with:
- cvs -d :pserver:anonymous@source.otrs.org:/home/cvs login
- password is: cvs
To check out the 'HEAD', which is the current version in development (experts and adventurous individuals recommended only):
- cvs -z3 -d :pserver:anonymous@source.otrs.org:/home/cvs co otrs
Checking out of a specific OTRS version can be done by using a release tag:
- cvs -z3 -d :pserver:anonymous@source.otrs.org:/home/cvs co -r rel-2_4otrs
A web viewer allows you to browse the repository and compare revisions.
