单独用做关系代词，引导非限制性定语从句，可放在主句以前(常译为：正如)或以后(常译为：这一点)，且主从句之间通常要用逗号隔开。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.
正如全部一切已经移到云端，在工业界做为一种提升员工效率的方式，虚拟化的远程桌面变得愈来愈流行。

用做介词，意为“做为”、“看成”、“充当”。如：
as a way to enhance employee's productivity.


What is X2Go?

GPL-ed的讨论
NX闭源的同时NX库被标为曾经使用GPL协议
这里的while你要根据前文说的先后，肯定究竟是指的是后来仍是可是的意思


As everything is moved to the cloud, virtualized remote desktop becomes increasingly popular in the industry as a way to enhance employee's productivity.
正如全部一切已经移到云端，在工业界做为一种提升雇员效率的方式，虚拟化的远程桌面变得愈来愈流行。
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.
尤为对须要常常漫游，横跨多个位置和设备的这些人，远程桌面容许他们无缝地保持链接到它们的工做环境。
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.
远程桌面对雇主来讲也是有吸引力的，在工做环境中实现增长（灵敏度）敏捷性与灵活性，因为硬件的整合，桌面的安全强化等方面，实现了更低的IT花费。
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，固然不缺乏启动远程桌面环境的选择，有不少协议(e.g., RDP, RFB, NX)和客服实现(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.
从这些包中脱颖而出的有X2Go--一个开源实现(GPLv2)，基于NX的远程桌面服务器与客户端。
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，我将要展现如何使用X2Go为linux vps创建远程桌面环境。


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的历史能够追溯到NoMachine公司的NX技术。NX远程桌面协议设计用来处理低带宽和高延迟的网络链接。
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.
后来，当NX库许可证到期时，NX转向了闭源。这致使一些基于NX远程桌面方案的开源实现，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都有哪些能够摆到桌面上的收益呢？X2Go继承了全部NX技术的高级特性，所以很天然地在慢速网络链接之上工做的很好。
Besides, X2Go boasts of an excellent track record of ensuring security with its built-in SSH-based encryption.
除此以外，X2Go自诩是一个完美的记录跟踪，用它内置基于SSH的加密确保安全。
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.
再也不须要手动创建一个SSH隧道。X2Go伴随着开箱即用的声音支持，它意味着在远程桌面的音乐回放经过网络被转发（经由脉冲音频），并注入本地扬声器。
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，你在远程桌面中运行的应用程序，能被无缝地在本地桌面上渲染为一个独立的窗口，给你一个应用程序就是运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，这些是它强大特性中的一些，正是基于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.
正如其它远程桌面服务器同样，X2Go server也有已知的兼容性问题。像KDE3/4,Xfce,MATE和LXDE这样的桌面环境对X2Go server都比较友好。
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，你的里程会受到其它桌面管理器的影响。例如，最新版本的GNOME 3, KDE5，Unity与X2Go不兼容。
If the desktop manager of your remote host is compatible with X2Go, you can follow the rest of the tutorial.
假如你远程主机的桌面管理器兼容X2Go，请接着阅读指南的其他部分。


Install X2Go Server on Linux

X2Go consists of remote desktop server and client components. Let's start with X2Go server installation.
X2Go 由远程桌面服务器和客户端组件组成。让咱们开始X2Go server安装。
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.
我假设你已经在远程主机上启动并运行了一个X2Go兼容的桌面管理器，我将在这个机器上安装X2Go服务器。
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组件没有一个在系统引导时而启动的独立服务。你只须要确保ssh服务启动并运行。
