NoMachine's licensing
by brian mullan 03 Feb '11

03 Feb '11

I asked nomachine and here is their actual license. As I'd suspected the GPL components that they use NoMachine points out were GPL already and nearly 80% of the overall NX project. Given that I'm not sure they can copyright those modules as they were based on other GPL projects... see URL: http://www.nomachine.com/ar/view.php?ar_id=AR10B00018 Under the NoMachine EULA <http://www.nomachine.com/licensing> it limits their copyright to the following programs: *4.1 Commercial NoMachine Software NoMachine Commercial Software consists of the following computer programs that have been developed by NoMachine: - nxserver - nxnode - nxmanager - nxclient - nxapplet - nxstat NoMachine owns the copyrights and intellectual property in and to each item of NoMachine Commercial Software.* The EULA also names all of the Open Source NoMachine programs separately that remain open. The URL that Erik provided says: Note also that to maintain the code ununcumbered of copyright, patents and licensing issues, it is required that you agree on giving to NoMachine a *Joint Copyright Assignment, granting the right to use your contributions in future NoMachine software, being this future software open or closed source and intended for commercial or non commercial use*. Such a JCA is standard in the industry, being required, for example, to contribute to Apache or to some projects sponsored by the GNU FSF. While *NoMachine releases its OSS software under the GPL license (a non-whitdrawable deal, ensuring that the software you contributed will be freely available forever under the terms of this same license*),* it is a requisite that NoMachine will maintain the full copyright on the software it develop*s. So any code anyone's contributed since 2004 to NoMachine's programs (see the above list) just gives NoMachine JOINT copyright with the contributors. There's only a question if any of x2go's current modules were directly derived from NoMachine's above "programs": libssh nxcomp nxcompext xcompshad nxproxy x2goagent x2goclient x2gognomebindings x2goplugin x2goserver Brian *Article: #AR10B00018* Added on: 2004-10-04 Last Modified: 2011-01-12 Applies to: NX Licensing *Under what kind of license is NX distributed?* NX Server and NX Client are commercial products, distributed under a closed source licence <http://www.nomachine.com/licensing> but all the core libraries (for example libraries implementing X protocol compression), the modified X11 transport libraries (which implement proxying of any standard X client) and the NX agent (the program that runs X sessions on behalf of the user) are released under the GNU General Public Licence. They represent a huge part of the project, currently nearly 80% of all the time and resources dedicated to NX development.

They have the copyright on all code in NX, see their contribution guidelines: http://www.nomachine.com/ar/view.php?ar_id=AR12B00113 To spell it out: Nomachine can relicense the NX code any which way they want. BTW this was the first google result for the query "contribute nomachine nx", a few seconds research would have saved many emails... Erik

What is this error that I get when installing x2godesktopsharing on Ubuntu? Setting up x2godesktopsharing (3.0.1-2) ... [: 36: x2gousers:x:105:ubuntu: unexpected operator Also I upgraded the server to 3.0.99 so which sudo entries can I now remove from /etc/sudoers? %x2gousers ALL=(ALL) NOPASSWD: /usr/bin/x2gopgwrapper <== can all of these sudo entries be removed?

Once the GPL license is on a code base ALL derivatives that are distributed in any manner are covered under the GPL no matter who makes them. <snip> > Greets, > Mike > Regards, Gerry

X2go GIT Repo - Patches?
by Moritz Struebe 02 Feb '11

02 Feb '11

Hi Mike, as there now is an "official" git repo. What shall we do with the work we did? There was quite a bit of dependency-cleanup and build fixing involved to get things running at launchpad. Shall we mail the patches to the mailing list or will you pull them from our server? Or do you rather want the patches sent to another mail address? Cheers Morty -- Dipl.-Ing.
