Graphical interface remote login install FreeNX based on NX technology

Article title: graphic interface remote logon install FreeNX based on NX technology. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.

Log on to the server using ssh normally Open the terminal and run Sudo gedit/etc/apt/sources. list Add the freeNX Source. I have tried other sources provided on the internet. I only have this source to connect. Deb http://mirror.ubuntulinux.nl feisty-seveas freenx The deb-src http://mirror.ubuntulinux.nl feisty-seveas freenx Download and install the GPG key Wget http://mirror.ubuntulinux.nl/seveas.gpg Sudo apt-key add seveas. gpg Update and install freeNX Sudo apt-get update Sudo apt-get install freenx The installation is complete, but some modifications are required for normal use, mainly because the font file location of the new system has changed. Gedit/usr/lib/nx/nxloadconfig Open, which is about 266 rows. the original file is: [ -z "$APPLICATION_LIBRARY_PRELOAD" ] && APPLICATION_LIBRARY_PRELOAD="$APPLICATION_LIBRARY_PATH/libX11-nx.so.6.2:$APPLICATION_LIBRARY_PATH/libXext-nx.so.6.4:$APPLICATION_LIBRARY_PATH/libXcomp.so:$APPLICATION_LIBRARY_PATH/libXcompext.so.1:$APPLICATION_LIBRARY_PATH/libXrender-nx.so.1.2" Replace it with (so many are actually a line of content ): [ -z "$APPLICATION_LIBRARY_PRELOAD" ] &&APPLICATION_LIBRARY_PRELOAD="$APPLICATION_LIBRARY_PATH/libX11-nx.so.6.2:$APPLICATION_LIBRARY_PATH/libXext-nx.so.6.4:$APPLICATION_LIBRARY_PATH/libXcomp.so:$APPLICATION_LIBRARY_PATH/libXcompext.so:$APPLICATION_LIBRARY_PATH/libXrender-nx.so.1.2" Or the first line of this file. the original file is: AGENT_EXTRA_OPTIONS_X="-fp /usr/share/X11/fonts/misc:/usr/share/X11/fonts/cyrillic:/usr/share/X11/fonts/Type1:/usr/share/X11/fonts/CID:/usr/share/X11/fonts/100dpi:/usr/share/X11/fonts/75dpi:/var/lib/defoma/x-ttcidfont-conf.d/dirs/TrueType:/var/lib/defoma/x-ttcidfont-conf.d/dirs/CID" Replace it with (note:-fp is followed by a space ): AGENT_EXTRA_OPTIONS_X="-fp /usr/share/fonts/X11/misc/,/usr/share/fonts/X11/Type1/,/usr/share/fonts/X11/75dpi/,/usr/share/fonts/X11/100dpi" Open another file. Gedit/etc/nxserver/node. conf Add a space after the file (note:-fp ): AGENT_EXTRA_OPTIONS_X="-fp /usr/share/fonts/X11/misc/,/usr/share/fonts/X11/Type1/,/usr/share/fonts/X11/75dpi/,/usr/share/fonts/X11/100dpi" After installation, run the following command to test the NX server: Current status: Nxserver -- status Restart: Nxserver -- restart However, I found that users can log on without adding them to the NX userlist. (Later I checked the information and found that the new version of freenx was verified using PAM. as long as the user can log on to ssh, it is very convenient to add the user to the freenx database .) For the Linux client, you can install it from the source mentioned above: Sudo apt-get install nxclient Winxp client above, I use nomachine out, free, download http://www.nomachine.com/download-client-windows.php here Download and install nxclient-3.2.0-10.exe: Enter the session item as needed. the host is 218.192.168.15, the default port is 22, and the network connection mode is Lan. Next, select Unix-GNOM and set the following expected resolution, for example, 1024*768, by default, the next step is configured. To make the display speed faster, set all available memory in configure-advanced-cache to the maximum. Then, enter the user name and password to log on. The password is fast and secure. it is applicable to scenarios where multiple users need to share xwindow. The most frequently asked connection questions on the Internet: When the xp end cannot be connected, a message such as "freenx -- status =" suincluded, running "may be displayed. I solve this problem. Delete C: \ Program Files \ NX Client for Windows \ share \ keys \ server. id_dsa.key on the xp end so that you can log on. If you still cannot log on, copy the server/var/lib/nxserver/home /. ssh/client. id-dsa.key to xp End C: \ Program Files \ NX Client for Windows \ share \ keys inside try? However, the key verification settings should be in the two configuration files mentioned above. The system provides several verification methods, and the key is one of them. you can explore it.
