玩 Linux 系統(tǒng)，會(huì)經(jīng)常用到遠(yuǎn)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(jù)說(shuō)速度比 VNC 還快，甚至可以在只有 10k 的帶寬環(huán)境下運(yùn)行。 而且畫面也比 VNC 的清楚。

使用 NoMachine 需要配置服務(wù)端和客戶端。

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 .

[root@rac2 /]# mkdir /windows

[root@rac2 /]# mount -o username=dave,password=888 //192.168.6.80/tmp /windows

[root@rac2 /]# cd windows/

[root@rac2 windows]# ls

nxclient-3.4.0-7.i386.rpm nxnode-3.4.0-14.i386.rpm nxserver-3.4.0-14.i386.rpm

[root@rac2 windows]# ls -lrt

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(zhí)行腳本：

[root@rac1 windows]# chmod 755 /usr/lib/cups/backend/ipp

查看 NXserver ：

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

NX> 900 Connecting to server ...

NX> 110 NX Server is running.

NX> 999 Bye.

[root@rac2 Server]#

二 . 客戶端

Windows 客戶端下載：

http://www.nomachine.com/download-client-windows.php

安裝完之后去連服務(wù)端即可。

運(yùn)行之后，看配置：

在這里我們需要輸入 Host 和 遠(yuǎn)程桌面類型。 現(xiàn)在基本用的是 KDE 和 GNOME 。 如果 Linux 只安裝了一個(gè)，就要選對(duì)。

下面還有一個(gè)選擇網(wǎng)絡(luò)類型的。

連接之后的畫面：

這里有兩點(diǎn)注意的地方：

1. 不能用 root 用戶進(jìn)行連接

2. 如果遇到一下問(wèn)題，請(qǐng)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."

NoMachine 官網(wǎng)對(duì)這個(gè)錯(cuò)誤做了說(shuō)明：
