UltraVNC (sometimes written uVNC), an open-source remote-administration/remote-desktop-software utility for Microsoft Windows, uses the VNC protocol to control/access another computer remotely over a network connection. Limited to single monitor displays.

Features

UltraVNC allows the use of a remote computer as if the user were in front of it. This is achieved by sending mouse movements and key-presses to the remote computer, and replicating the remote computer's display (subject to differences in resolution) locally in real time. UltraVNC bears a strong resemblance to RealVNC Free Edition. However, in addition to remote control it adds various features, such as an encryption plugin to secure the client/server connection. It also supports file transfers, chat functionality and various authentication methods. The two computers must be able to communicate across a network, such as a local subnet, internal network, or the Internet. The software is free and distributed under the terms of the GNU General Public License.

It can use an optional mirror driver, to be installed on the remotely controlled computer, for fast and efficient notification of screen changes with very low CPU load.

History

UltraVNC is developed in the C, C++, and Java programming languages.

The 1.0.6.4 release added support for working as a Windows service under User Account Control (UAC).

Reverse control

UltraVNC is notable as the base for free no-install remote help desk options including UltraVNC Single Click ("SC") and PCHelpWare. These operate by generating pre-configured executables that can be downloaded and run on systems needing support; these applications then connect back to server software running on the system providing support.

Other projects

IP via Email is a freeware program to support VNC software and other remote control programs. It provides the dynamic IP address of the system through an email address of the user or other support services. It is a program that runs as a service of the system operating. It run in automatic execution and, also when computer restarted, it’s able to alert the user when into the remote system the dynamic IP is changed. It is also able to send different parameters updated of computer. To know better and to download www.microproject.eu/ipviaemail.
