FreeNX

Here are the steps to get FreeNX up and running. It is fairly straight forward and easy, although there is one point that can be a little confusing but that is during the client setup, not the server.

First, log into your hda and open a terminal window.

Second, run this command to install FreeNX:

bash code
​yum install freenx-server​

That's it. FreeNX should now be installed and running on your HDA. In order to use FreeNX, you will need a client to connect with. Go to http://www.nomachine.com/download.php and select the one for your appropriate operating system.

After downloading and installing the client, you will need to copy the client.id_dsa.key into the client. What I did was to scp the key from my server (/etc/nxserver/client.id_dsa.key) to my local system, open the file in a text editor, copy everything in it and paste it into the client. In my client this was under "Configure" then on the "General" tab, there is a button labeled "Key". This is where I pasted the client key information.

• NOTE* If you miss or overlook the step for the client key configuration, the client will attempt to use a default key for the HDA, and this does not work.

Finally, save the configuration, and then run the client to log into the HDA.

Since the Fedora 12 update some users have reported the following error when trying to log into their HDA after installing using the method above.

cat: /var/lib/nxserver/db/running/sessionId{(STDIN)}: 
   No such file or directory NX> 280 Exiting on signal: 15

A work around for this is to open:

/etc/nxserver/node.conf

And add the following to the end of the file:

Text
​COMMAND_MD5SUM="md5sum"​

In case you receive any error messages or notification from Fedora that some applications (like gnome-settings-daemon) crashed, you might want to install free NX server from Nomachine web site.

Go to Nomachine's web site and download a Free Nomachine NX server (http://www.nomachine.com/download-package.php?Prod_Id=1352) for Linux i386 RPM. It consists of three separate downloads: client RPM, node RPM and Server RPM. You can read on their web site detailed info on how to install it and in what order - pretty straightforward. Here is what you need to do to get it installed on Fedora 12:

1) Uninstall completely FreeNX server from your HDA (use Add/Remove software);

2) Go to your System Preferences-->Add Remove Software and do search for "audiofile" (without quotes). It will find for you a piece of software "audiofile-1:0.2.6" and "audiofile-devel-1:0.2.6. Install both development files and a library;

3) Do search (the same Add/remove software) for "libstdc". It will find C++ libraries, different versions. Install latest ones in case they are not yet installed;

4) Do search (same place) for "GLIBC" - it will find a few libraries there. Install the latest ones in case they are not yet installed

That's it. Then go to terminal and do "sudo rpm -i" command for all three packages that you downloaded before. Here are the commands (you need to run these from the folder where you have dowloaded them):

[root@localhost ~]# cd /folder_where_files_were_downloaded, example

cd /home/frank/Downloads/

• [root@localhost Downloads]# rpm -Uvh nxclient-3.4.0-5.i386.rpm
• [root@localhost Downloads]# rpm -Uvh nxnode-3.4.0-6.i386.rpm
• [root@localhost Downloads]# rpm -Uvh nxserver-3.4.0-8.i386.rpm

It may complain something about permissions for CUPS that you may just ignore. Or if you want, you can follow the instructions the installer gives you, and fix permission problem and re-install. Keep in mind, that these three packages are easily removable thru Add/Remove interface in System Preferences.

Last step. Download and install NX client software (not the same as above) from the same Nomachine's web site. You need to install client software on the machine that you want to access your HDA from. In my case it's a Windows based laptop - so I chose Windows version. Once installed, you can run it with default Key and default settings. Just choose Configure button, and on General tab, choose UNIX---Gnome for the desktop. No need to export/import Keys - can run with default installed keys. For added security, you can later change Keys as described in their knowledge base (article #AR01C00126).
