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.

煩請協助審議，以利商業公司內推行自由軟體相關，謝謝！
