玩Linux系統，會(huì )經(jīng)常用到遠程桌面軟件。我一直用的2個(gè)是Xmanager 和 VNC。今天看到一個(gè)新軟件：NoMachine。NoMachine NX 是一個(gè)快速的終端服務(wù)器和虛擬桌面軟件，基于 X11 協(xié)議。據說(shuō)速度比 VNC 還快，甚至可以在只有 10k 的帶寬環(huán)境下運行。而且畫(huà)面也比VNC 的清楚。

使用NoMachine 需要配置服務(wù)端和客戶(hù)端。
一. 服務(wù)端
服務(wù)端需要安裝3個(gè)包：
nxserver-3.4.0-12.i386.rpm
nxnode-3.4.0-11.i386.rpm
nxclient-3.4.0-7.i386.rpm
Linux 32bit 的下載地址是：
http://www.nomachine.com/download-package.php?Prod_Id=2068
下面是NoMachine網(wǎng)頁(yè)的上一個(gè)使用說(shuō)明：
1. Download the RPMs
2. Change your working directory to the location where you saved the package and install it by running from a console:
# sudo rpm -i nxclient-3.4.0-7.x86_64.rpm
# sudo rpm -i nxnode-3.4.0-14.x86_64.rpm
# sudo rpm -i nxserver-3.4.0-14.x86_64.rpm
If you don't have the sudo utility installed, log on as superuser ("root") and run the commands without sudo.
Note: click here for detailed instructions on how to install the NX Client, NX Node and NX Server packages. The NX service can be controlled by the command /usr/NX/bin/nxserver --status|--start|--stop|--restart. Additional commands are available to configure the server. Try /usr/NX/bin/nxserver --help for more information. Please, don't forget to download and read the NX Server Administrator's Guide available here.

CUPS Printing Backend
The NX Client set-up procedure detected that your "IPP CUPS" printing
backend doesn't allow printing from the NX session. In order to have
printing support in your NX system, you need to set proper permissions
on the IPP backend. Please execute:
chmod 755 /usr/lib/cups/backend/ipp

上面有提示我們執行腳本：

查看NXserver ：
[root@rac2 Server]# /usr/NX/bin/nxserver --status

二. 客戶(hù)端
Windows 客戶(hù)端下載：
http://www.nomachine.com/download-client-windows.php
安裝完之后去連服務(wù)端即可。
運行之后，看配置
在這里我們需要輸入Host 和 遠程桌面類(lèi)型。 現在基本用的是KDE 和 GNOME。 如果Linux 只安裝了一個(gè)，就要選對。
這里有兩點(diǎn)注意的地方：
1. 不能用root用戶(hù)進(jìn)行連接
2. 如果遇到一下問(wèn)題，請檢查環(huán)境變量：
To launch a desktop session, KDE or GNOME, the corresponding
commands, either startkde or gnome-session must be set in the PATH.
If the command is not available in the PATH, an error message like:
"Cannot run 'startkde'. Please check that the requested application is in
the system PATH and that you have the rights to execute it."
