License Information
Refer to the Polycom RealPresence DMA 7000 System Offer of Open Source Software for a list of the open
source software packages used in the Polycom RealPresence DMA system, the applicable license for each,
and the internet address where you can find it. To obtain the source code for any of these packages, email

Modifying Open Source Code
The Polycom RealPresence DMA system software is not combined with or otherwise linked to any open
source libraries, but the CentOS software is. The LGPL v2.1 license allows you to modify the LGPL code
included with CentOS, recompile the modified code, and re-link it with the CentOS code. Note that although
you’re free to modify the included LGPL modules 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
1 Obtain the source code for the module you want to modify.
2 Modify the source code and compile it.
3 Go to Admin > Local Cluster > Security Settings, select Allow Linux console access, and click
Update.
4 Contact Polycom Global Services for the root password for the Polycom RealPresence DMA server.
5 Use ssh to log into the server as root.
6 Upload the modified software via wget or scp.
7 Find the module you’re replacing and install the new version to that location.
8 Reboot the system.
