Third-Party Software

Open Source Software

The Polycom DMA system uses several open source software packages, including the CentOS operating system. CentOS is an enterprise-class Linux distribution that contains hundreds of open-source components. For more information about CentOS, visit http://www.centos.org/.

The packages containing the source code and the licenses for all the open- source software, including CentOS and its components, are included on the Polycom DMA system software DVD, mostly in the /SRPMS directory.

Modifying Open Source Code

The LGPL v2.1 license allows you to modify the LGPL code we use, recompile the modified code, and re-link it with our proprietary code. Note that although you’re free to modify the LGPL modules used in the Polycom DMA system in any way you wish, we cannot be responsible if the changes you make impair the system.

To replace an LGPL library with your modified version

1On the DMA DVD, find the source code for the module you want to modify.

2Modify the source code and compile it.

3Go to Admin > Local Cluster > Security Settings, select Allow Linux console access, and click Update.

4Contact Polycom Global Services for the root password for the Polycom DMA server.

5Use ssh to log into the server as root.

6Upload the modified software via wget or scp.

7Find the module you’re replacing and install the new version to that location.

8Reboot the system.
