FreeNX遠端控制Linux平臺解決方案

FreeNX是近年來繼VNC之後新出現的遠端控制解決方案，基本原理是將XWindows的信號壓縮後傳輸到遠端用戶端顯示，而VNC是直接截取螢幕影像處理傳輸。 這樣，在同樣的傳輸通道條件下，FreeNX可以比VNC提供更好的操作感和即時性；也正因為其實現原理依賴于XWindows，因此FreeNX目前也就不支援將Windows作為遠端控制伺服器端。

一、FreeNX伺服器端安裝

1、HTTP://www.aliyun.com/zixun/aggregation/10482.html">下載軟體：

#wget HTTP://fedoranews.org/contributors/rick_stout/freenx/freenx-0.3.1-0.fdr.0.noarch.rpm

#wget HTTP://fedoranews.org/contributors/rick_stout/freenx/nx-1.4.0-0.fdr.4.i386.rpm

#wget HTTP://www.linux-tip.net/cms/workshop/freenx_FC3/expect-5.42.1-1.i386.rpm

#wget ftp://fr.rpmfind.net/linux/redhat/9/en/os/i386/RedHat/RPMS/nc-1.10-18.i386.rpm

2、安裝軟體：

#rpm －ivh nc-1.10-18 RPM for i386

#rpm -i nx-1.4.0-0.fdr.4.i386.rpm

#rpm -i expect-5.4.2.1-1.i386.rpm

#rpm -i freenx-0.3.1-0.fdr.0.noarch.rpm

3、配置nxserver

# /usr/bin/nxsetup --install

Setting up /etc/nxserver ...done

Setting up /var/lib/nxserver/db ...done

Setting up /var/log/nxserver.log ...done

Setting up known_hosts and authorized_keys2 ...done

Setting up permissions ...done

Ok, nxserver is ready.

PAM authentication enabled:

All users will be able to login with their normal passwords.

PAM authentication will be done through SSH.

Please ensure that SSHD on localhost accepts password authentication.

You can change this behaviour in the /etc/nxserver/node.conf file.

Have Fun!
