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).
