NX is used for full desktop and command line access similar to Remote Desktop on Windows.
NoMachine NX is an enterprise-class solution for secure remote access, desktop virtualization, and hosted desktop deployment built around the self-designed and self-developed NX suite of components. Thanks to its outstanding compression, session resilience and resource management and its integration with the powerful audio, printing and resource sharing capabilities of the Unix world, NX makes it possible to run any graphical application on any operating system across any network connection. Via NX accessing remote desktops, servers and applications, whatever their location, is just as fast, easy and secure as if you were sitting in front of them. Together with easy-to-use management, deployment, and monitoring tools, NoMachine NX makes it possible to transform any traditional desktop computing environment into a centrally managed, globally accessible, virtual desktop infrastructure.
Please note that NX is no longer supported.
