Please see our Licensing Terms page for current information on licensing.

Linux STREAMS (LiS)

OpenSS7 release of Linux STREAMS (LiS) are released under the GNU General Public License Version 2. However, because OpenSS7 owns copyright on modification made to the GCOM releases, if you are interested in the orginal LGPL licensing terms, please see our Licensing Terms page and the home page of OpenSS7 Corporation.  

Otherwise, modifications and application linked to the OpenSS7 Linux STREAMS (LiS) releases are licensed under the GNU Public License Version 2 by nature of the GPL licensing on the primary work.  

Linux Fast-STREAMS (LfS)

OpenSS7 Linux Fast-STREAMS is released uner the GNU General Public License Version 2. However, because OpenSS7 owns copyright to all code in this package, and because OpenSS7 retains rights in the copyright, if you are interested in licensing terms different than the GPL, please see our Licensing Terms page and the home page of OpenSS7 Corporation.  

STREAMS Networking (strxns, strxnet, strinet, strsctp)

The strxns package contains some components released under GPL by other authors. Code in this package originally created by the OpenSS7 Project, are release under GPL, with the option to commercial license.  

The strxnet package contains an XTI/TLI library released under the LGPL. Note that when the strxnet XTI/TLI library is used with the strinet or strsctp packages, the GPL nature of those packages impose a GPL requirement on the applications using the library. If you need licensing other than the GPL with strinet or strsctp, please see our Licensing Terms page and the home page of OpenSS7 Corporation.  

The strinet is released under the GNU General Public License Version 2, however, OpenSS7 retains rights, permitting commercialy licensing of this package.  

The strsctp is released under the GNU General Public License Version 2, however, OpenSS7 retains rights, permitting commercialy licensing of this package.  

STREAMS SS7 Stack

By nature of the fact that the LiS STREAMS package upon which this version is built permits releasing proprietary libraries, I have upgraded the license on this version to the GNU General Public License Version 2. Again, the copyright holder(s) (author(s)) reserve all rights.

The copyrights on OpenSS7 STREAMS SS7 Stack are held by OpenSS7 Corporation. If you are interested in licensing terms which are different from the GPL Version 2 license, please see our Licensing Terms page and the home page of OpenSS7 Corporation.

Otherwise, modifications and applications linked to the OpenSS7 STREAMS SS7 Stack are licensed under the GNU Public License Version 2 by nature of the GPL licensing on the primary work.

Test Programs

The OpenSS7 test programs used to test the OpenSS7 stack are licensed under different terms than the GPL. These programs are only provided to demonstrated the usability, conformance and stability of the OpenSS7 stack and may not be distributed, modified or copied in any way. These programs are the property of OpenSS7 Corporation.

Contributed test programs are the property of the respective copyright holders.

Linux Kernel Version

The OpenSS7 Linux Kernel stack is licensed under the terms of the GNU General Public License Version 2. However, the copyright holder (author) reserves all rights. This means that if you are interested in licensing terms which are different from the GPL Version 2 license, you are free to discuss this with the copyright holders on the original works. Modifications to the OpenSS7 Linux Kernel stack are licensed under the GNU General Public License Version 2 by nature of the GPL licensing of the primary work. For other licensing terms on modifications to the OpenSS7 stack, please contact the respective copyright holders.

Nothing in the GPL Version 2 licensing of the Linux kernel version of the SS7 stack should be construed as a restriction on its use by commercial applications. Just because the Linux Kernel version (sockets) stack is GPL'ed does not mean that applications which use the OpenSS7 stack are necessarily opensource or freely available to the public.

Be careful that you do not confuse the Linux Kernel (sockets) version, which is now deprecated, with the STREAMS version which does not permit proprietary programs to be linked without separate licensing.
