RealVNC 5.2.1

A free remote control application for Linux, Microsoft Windows and Mac OS X OSes
RealVNC is a free and cross-platform application that provides users with a remote control software, allowing them to easily connect to and interact with a computer on which a VNC (Virtual Network Computing) server is installed.

The project comes with both server and client components, allowing incoming and outgoing connections to the computer where it is installed, anywhere on the Internet. Supported operating systems include GNU/Linux, Microsoft Windows and Mac OS X.

Key features include support for both 128-bit and 256-bit AES encryptions, VNC authentication, system authentication, single sign-on authentication, powerful deployment tool, optimized performance, file transfer, printing, and chat.

While the server component runs entirely in the background, the viewer part comes with a graphical user interface that is both familiar and easy to use. It is pretty much the same as the one of any other VNC viewer application.

To connect to a remote computer that runs a supported VNC server, all you have to do is to enter the IP address and port of the respective machine, as well as to choose an encryption setting.

An Options dialog will allow users to quickly set various settings, such as to adapt the network speed for best quality/compression, as well as to enable or disable the full screen mode, toolbar, and scale to window size options.

In addition, clicking the “Advanced” button will display far more settings than the basic layout, including display scaling, keyboard and mouse inputs, file transfers, chat, clipboard sharing, single sign-on, proxy, printer sharing, and logging.

Advanced users who are not satisfied with the default configuration, can find a bunch of parameters to tune on the “Expert” tab. The settings can be used for a single connection or for all new connections.

In conclusion, RealVNC provides a sophisticated VNC viewer/server application for the GNU/Linux platform. We have to admin that the minimal graphical user interface can be drastically improved, because right now it looks like a Windows 95 application.
