請教遠端登入免費軟體於商業公司使用審議 2010/10/14 19:52  (4 Years, 2 Months ago) Karma: 0  
Dear Sir

不好意思又來請教,想請協助審議公司內未來推行可使用的自由軟體
這兩套也是標榜免費的遠端連線軟體,但不知道是否可合法使用於公司內
想請這邊的專家協助審核在商業公司內使用是否有版權上的疑慮
公司內軟體之使用並不會修改程式或安裝於商品販售,主要為員工內部工作上的使用
請協助確認標榜免費在商業公司內使用之合法性,或推薦其他自由軟體(可以達到相關功能性的軟體)
謝謝各位!

軟體名稱:Xming
功能描述:遠端登入到工作站
預期效益:可取代Xmanager付費軟體,達到遠端登入Unix、Linux、Solaris等圖型化環境。
相關版權敘述:www.straightrunning.com/XmingNotes/
提到免費使用的內容:在軟體安裝後裡的Copying.txt檔,提到「The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too.」


軟體名稱:XWinLogon Win32 X-Server
功能描述:遠端登入到工作站
預期效益:可取代Xmanager付費軟體,達到遠端登入Unix、Linux、Solaris等圖型化環境。
相關版權敘述:www.calcmaster.net/visual-c++/xwinlogon/
提到免費使用的內容:在官方網頁內提到「Based on the popular Cygwin environment for Windows, this is just an interface to the X Server to allow you to connect to another Unix/Linux box from your Windows computer. It supports SSH, XDMCP, RSH, SSH Compression, backing store, OpenGL, windows clipboard integration, single windows mode, multi windows mode, and multi external window manager windows mode. The interface is licensed under the GNU GPL, and all other software is licensed by its respective creators. More can be learned about the software at www.cygwin.com. See a screenshot of the software. Also check out the product comparison between XWinLogon, XWin32 and eXceed. 」
這套比較特別的地方是它主要利用到cygwin這套軟體當核心,它也是免費的,在這邊有提到cygwin.com/license.html 「This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License (GPL) as published by the Free Software Foundation version 2 of the License.
This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. 」


煩請協助審議,以利商業公司內推行自由軟體相關,謝謝!

Hi syman888,

以下簡單回覆你的問題。

一、關於Xming

(1)從SourceForge上(http://sourceforge.net/projects/xming/files/)下載到純粹軟體的部份,是依其個別元件的自由軟體授權條款來運作;(2)從Xming的專題網站(http://www.straightrunning.com/XmingNotes/)下載的技術文件與程式,則依特別向其恰談商業化的授權方式。

這個專案的運作方式較為複雜:(1)基礎的元件有MIT、BSD授權的軟體,但(2)Xming專題網站的架設者將這些元件重新整理,也加工使其最佳化,所以從Xming專題網站所下載的程式元件與技術文件,其要求商業使用者必須另外向其取得授權,而非商業使用者,亦僅只有一年的使用期間,並且須要做某程度的捐獻動作。

這些聲明公布於此:http://www.straightrunning.com/XmingNotes/terms.php#head-14

1. Xming installers and components are Public Domain if put on [WWW]SourceForge, by me. You can do what you like with Public Domain releases including freely distributing them; they still retain all original authors' licenses appropriately, but I have relinquished my rights over them. However, everything downloaded from this website (for Project Xming) has this mandatory agreement.

2. Some Xming components (e.g. PuTTY/plink.exe and sha1.c used in render/glyph.c for Xming.exe) contain cryptographic items and as such are illegal in countries where encryption is outlawed. The encryption methods and algorithms used are freely available in the Public Domain and therefore not subject to export controls in Europe. If you are a U.S. citizen exporting Xming code: you are solely responsible for being compliant with any applicable U.S. Export Administration Regulations.

3. Commercial and Public Sector users, who want to use Xming Website Releases (fully or partially) in connection with their work, or incorporate any part of them in their products, must order a separate 'User' license or negotiate for a product distribution license. Here is the Xming License Order Form for different numbers of 'Users' (note: Xming installation on a shared computer can be counted as just one 'User' and a Site License allows unlimited numbers of 'Users' on Site owned equipment). Fee-charging academic or research institutions must obtain an Academic Site License in order to use Xming Website Releases. Licenses are for the lifetime of the product and come with access to one year of updates (i.e. this access has a small annual renewal fee).

4. Xming licenses are only available directly and no reselling or transfer is permitted or possible.

5. Private individuals, who want to use Xming Website Releases as sole user at home, will be given access to them for one year after making a small Donation to help fund the replacement equipment needed to further Xming development.

6. All customer information and emails are treated as confidential. No customer specific data will be disclosed on StraightRunning.com or by Colin Harrison to any third party without obtaining consent.

7. I Colin Harrison, in my sole discretion, have the right to suspend or terminate your access and use of my site, for any reason at any time.

8. Xming comes with ABSOLUTELY NO WARRANTY, to the extent permitted by applicable law i.e. all Project Xming components are provided "as is" with no implied fitness for any purpose. I accept NO LIABILITY for any loss or damage arising out of use of Xming or any Project Xming components i.e. use at your own risk.

Xming專案個別元件的授權說明,則可參加右列連結:http://www.straightrunning.com/licenses/

小結論是、Xming這個專案並不完全符合你所提出,完全免費在商業公司內部使用的期待。

二、關於XWinLogon Windows X Server

(1)可以在商業公司內部使用;(2)再散布的話須要提供程式原始碼。

這個專案比較單純,就同你所找的資料,XWinLogon Windows X Server(http://www.calcmaster.net/visual-c++/xwinlogon/)這個專案是一個橋接Windows使用環境到Unix/Linux Server的Interface,這個Interface是用GNU GPL來授權,而其使用的Cygwin(http://www.cygwin.com/)也是以GNU GPL來授權的,這代表你可以將這些程式拿來做不限目的的利用,但是如果再散布程式時,就肩負提供後手程式原始碼的義務。

所以依你的規劃,純粹在公司內部使用而不涉及產品製作以及再散布,是可以的。

希望以上的回覆對你有所幫助。
