VNC is available for general use under the conditions of the GNU General Public Licence. You should be aware of the terms and conditions of this licence, which is also contained in the distribution itself.
RealVNC is remote control software which allows you to view and interact with one computer (the "server") using a simple program (the "viewer") on another computer anywhere on the Internet. The two computers don't even have to be the same type, so for example you can use VNC to view an office Linux machine on your Windows PC at home. VNC is freely and publicly available and is in widespread active use by millions throughout industry, academia, and privately.
I can't stand when installation procedures try to sneak up on it and install spyware, "search bars", and other evil stuff like this. But once you say no, then you go into installation, and it still tries to sneak it in unnoticed. Shame.
Took me less than 5 minutes to get everything up and running. 256 AES encryption if needed, many different logon methods. Everything is easy for the not so experienced computer user..
None that I can think are worth posting
Try this and let me know what you think, as I believe it is much better than Radmin, which claims it is by far the best program of its type. After visiting Radmin's website that compared it to other programs using stupid side by side video comparisons which in my opinion have really no facts, specifications, or descriptions of why Radmin surpasses all the rest.. Made me post this review (My first review ever on here) because I think this program RealVNC deserves much better reception than it seems to be getting.
