Second, run this command to install FreeNX:
[root@localhost ~]# 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.
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:
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.'''
