NoMachine 6 Now Available

Luxembourg, November 15th, 2017

NoMachine, a leader in cross-platform remote computing solutions, today announced the official release of NoMachine 6 which introduces a series of exciting new enhancements, including a revamp of its product families available for Windows, macOS and Linux.

A new Cloud Server product, a streamlined Linux Terminal Server family and the addition of the functionality of browser-based access to the entire enterprise-oriented range are just some of the exciting additions users can experience with this major software update.


Cloud Server

Cloud Server 6 becomes a gateway to the NoMachine infrastructure and sits at the top of the NoMachine product hierarchy in the eponymous product suite. It is dedicated to centralized access to all other servers in the NoMachine infrastructure including foreign hosts.

Linux Terminal Server

The virtual desktop for Linux functionality is now exclusive to the Terminal Server family. Enterprise Terminal Server for Linux replaces both Enterprise Server v.5 and Cloud Server v.5 when used for virtual Linux desktop sessions. Enterprise Terminal Server offers load-balancing of Terminal Server Nodes and failover as its predecessors did with the additional bonus of browser-based access.


NoMachine 6 also introduces the following enhancements:

i) Browser-based access for all enterprise products. Web-based access is no longer exclusive to Cloud Server.
This highly-requested functionality is available in all products of the Terminal Server and Cloud Server suites.

ii) Support for H.264 codec in WebRTC sessions. Web-based sessions can be streamed using the H.264
encoder on the server, provided the browser on the connecting client also supports the codec.

iii) Toggling the desktop's sharing availability. Access to the local desktop and requests to connect can
now be easily disabled for as long as the owner chooses without having to stop the NoMachine services entirely.

iv) Raspberry support. Raspberry has officially been added to the list of supported platforms. Both RPi2 and
RPi3 models can be used as connecting clients as well as pocket-sized servers.

v) Enhancements to clustered servers and failback mechanisms. Set-up of clustered environments is improved
for admins with the use of GUIDs to identify failover clusters and facilitate installation of new servers to a
NoMachine server federation.

vi) Automatic reconnection. Great news for NoMachine users who roam between networks at the office. NoMachine
automatically tries to reconnect you when the connection is lost.

vii) Automatic detection of a proxy server - NoMachine detects whether there is a Proxy server in place on the local
network through which outgoing traffic has to be tunneled.
