RealVNC: Control Remote Windows, Mac & Linux Systems Through VNC

Just a few days ago, we covered OnlineVNC, a VNC solution that allows you to control a remote PC via a web browser. Today, we will look into another VNC application called RealVNC, which is quite different from OnlineVNC in terms of the way it allows users to interact with a VNC server. Both the server and client (viewer) come packed into a single setup file. Instead of using the web browser, you need the Viewer application to access the shared machine from the remote location. Moreover, RealVNC supports multiple platforms, namely Windows, Mac OS X, Linux, Solaris, HP-UX and AIX, and has paid Viewer apps for Android and iOS as well. RealVNC is very powerful, and becomes quite user-friendly too once you get the hang of the VNC connection’s setup process. Read on for more details.

Once the application is installed, the installation setup will launch the Server control panel. To begin, you need to obtain a free license key from the product page. Select Visit our website to obtain license key option and click Next.
