一。as用法
http://www.yygrammar.com/Article/201410/3720.html
單獨用做關係代詞，引導非限制性定語從句，可放在主句以前(常譯爲：正如)或以後(常譯爲：這一點)，且主從句之間通常要用逗號隔開。如：
As everything is moved to the cloud, virtualized remote desktop becomes increasingly popular in the industry as a way to enhance employee's productivity.
正如全部一切已經移到雲端，在工業界做爲一種提升員工效率的方式，虛擬化的遠程桌面變得愈來愈流行。

用做介詞，意爲「做爲」、「看成」、「充當」。如：
as a way to enhance employee's productivity.


What is X2Go?

GPL-ed的討論
NX閉源的同時NX庫被標爲曾經使用GPL協議
這裏的while你要根據前文說的先後，肯定究竟是指的是後來仍是可是的意思


As everything is moved to the cloud, virtualized remote desktop becomes increasingly popular in the industry as a way to enhance employee's productivity.
正如全部一切已經移到雲端，在工業界做爲一種提升僱員效率的方式，虛擬化的遠程桌面變得愈來愈流行。
Especially for those who need to roam constantly across multiple locations and devices, remote desktop allows them to stay connected seamlessly to their work environment.
尤爲對須要常常漫遊，橫跨多個位置和設備的這些人，遠程桌面容許他們無縫地保持鏈接到它們的工做環境。
Remote desktop is attractive for employers as well, achieving increased agility and flexibility in work environments, lower IT cost due to hardware consolidation, desktop security hardening, and so on.
遠程桌面對僱主來講也是有吸引力的，在工做環境中實現增長（靈敏度）敏捷性與靈活性，因爲硬件的整合，桌面的安全強化等方面，實現了更低的IT花費。
In the world of Linux, of course there is no shortage of choices for settings up remote desktop environment, with many protocols (e.g., RDP, RFB, NX) and server/client implementations (e.g., TigerVNC, RealVNC, FreeNX, x2go, X11vnc, TeamViewer) available.
在linux的世界中，固然不缺乏啓動遠程桌面環境的選擇，有不少協議(e.g., RDP, RFB, NX)和客服實現(e.g., TigerVNC, RealVNC, FreeNX, x2go, X11vnc, TeamViewer)可用。
Standing out from the pack is X2Go, an open-source (GPLv2) implementation of NX-based remote desktop server and client.
從這些包中脫穎而出的有X2Go--一個開源實現(GPLv2)，基於NX的遠程桌面服務器與客戶端。
In this tutorial, I am going to demonstrate how to set up remote desktop environment for Linux VPS using X2Go.
在本指南中，我將要展現如何使用X2Go爲linux vps創建遠程桌面環境。


The history of X2Go goes back to NoMachine's NX technology. The NX remote desktop protocol was designed to deal with low bandwidth and high latency network connections by leveraging aggressive compression and caching.
X2Go的歷史能夠追溯到NoMachine公司的NX技術。NX遠程桌面協議設計用來處理低帶寬和高延遲的網絡鏈接。
Later, NX was turned into closed-source while NX libraries were made GPL-ed. This has led to open-source implementation of several NX-based remote desktop solutions, and one of them is X2Go.
後來，當NX庫許可證到期時，NX轉向了閉源。這致使一些基於NX遠程桌面方案的開源實現，其中之一就是X2Go。
What benefits does X2Go bring to the table, compared to other solutions such as VNC? X2Go inherits all the advanced features of NX technology, so naturally it works well over slow network connections.
和其它方案例如VNC相比，X2Go都有哪些能夠擺到桌面上的收益呢？X2Go繼承了全部NX技術的高級特性，所以很天然地在慢速網絡鏈接之上工做的很好。
Besides, X2Go boasts of an excellent track record of ensuring security with its built-in SSH-based encryption.
除此以外，X2Go自詡是一個完美的記錄跟蹤，用它內置基於SSH的加密確保安全。
No longer need to set up an SSH tunnel manually. X2Go comes with audio support out of box, which means that music playback at the remote desktop is delivered (via PulseAudio) over network, and fed into local speakers.
再也不須要手動創建一個SSH隧道。X2Go伴隨着開箱即用的聲音支持，它意味着在遠程桌面的音樂回放經過網絡被轉發（經由脈衝音頻），並注入本地揚聲器。
On usability front, an application that you run on remote desktop can be seamlessly rendered as a separate window on your local desktop, giving you an illusion that the application is actually running on the local desktop.
在可用性方面，你在遠程桌面中運行的應用程序，能被無縫地在本地桌面上渲染爲一個獨立的窗口，給你一個應用程序就是運行在本地桌面的假象。
As you can see, these are some of its powerful features lacking in VNC based solutions.
正如你所看到的，這些是它強大特性中的一些，正是基於VNC方案所缺乏的。


X2GO's Desktop Environment Compatibility

As with other remote desktop servers, there are known compatibility issues for X2Go server. Desktop environments like KDE3/4, Xfce, MATE and LXDE are the most friendly to X2Go server.
正如其它遠程桌面服務器同樣，X2Go server也有已知的兼容性問題。像KDE3/4,Xfce,MATE和LXDE這樣的桌面環境對X2Go server都比較友好。
However, your mileage may vary with other desktop managers. For example, the later versions of GNOME 3, KDE5, Unity are known to be not compatible with X2Go.
然而，你的里程會受到其它桌面管理器的影響。例如，最新版本的GNOME 3, KDE5，Unity與X2Go不兼容。
If the desktop manager of your remote host is compatible with X2Go, you can follow the rest of the tutorial.
假如你遠程主機的桌面管理器兼容X2Go，請接着閱讀指南的其他部分。


Install X2Go Server on Linux

X2Go consists of remote desktop server and client components. Let's start with X2Go server installation.
X2Go 由遠程桌面服務器和客戶端組件組成。讓咱們開始X2Go server安裝。
I assume that you already have an X2Go-compatible desktop manager up and running on a remote host, where we will be installing X2Go server.
我假設你已經在遠程主機上啓動並運行了一個X2Go兼容的桌面管理器，我將在這個機器上安裝X2Go服務器。
Note that X2Go server component does not have a separate service that needs to be started upon boot. You just need to make sure that SSH service is up and running.
注意X2Go server組件沒有一個在系統引導時而啓動的獨立服務。你只須要確保ssh服務啓動並運行。
