TightVNC is a Free, Lightweight, Fast and Reliable Remote Control Software. TightVNC is a free remote control program package. With TightVNC, you can see the desktop of a remote machine and control it with your local mouse and keyboard, just like you would do it sitting in the front of that computer. TightVNC is:
1. free for both personal and commercial usage, with full source code available (GPL-licensed);
2. useful in remote administration, remote customer support, education, and for many other purposes;
3. cross-platform, available for Windows and Unix, compatible with other VNC software.

TightVNC is a remote control package derived from VNC, with many new features, improvements, and bugfixes over the standard VNC version. It works well with slow network links such as modem connections, provides more configuration options in the server, includes improved Java viewer, and more. The modified servers and viewers are fully compatible with the original VNC software.

How would I connect from the Internet to a machine in the internal network which is behind a router?
You should enable "port forwarding" in your router's configuration. Port forwarding allows passing external connections to computers in the internal network. Almost all routers support this type of redirection.
For example, to access VNC or TightVNC server running on default ports, a router can be configured such way that TCP connections to ports 5900 and 5800 would be passed to the same ports of a particular machine with a specified private IP address (typically 192.168.x.x).

VNC (an abbreviation for Virtual Network Computing) is a outstanding client/server program package allowing remote network access to graphical desktops. With VNC, you can access your machine from everywhere provided that your machine is connected to the Internet. VNC is free (released under the GNU General Public License) and it's available on most platforms.

Here you can find an enhanced version of VNC, called TightVNC, which includes a lot of new features, improvements, optimizations and bugfixes over the original VNC version, see the list of features below. Note that TightVNC is still free, cross-platform and compatible with the standard VNC. Many users agree that TightVNC is the most advanced free remote desktop package. And it's being actively developed so you can expect that TightVNC will become even better.

TightVNC can be used to perform remote control and administration tasks in Windows, Unix and mixed network environments. It can be very helpful in distance learning and remote customer support. Finally, you can find a number of additional VNC-compatible utilities and packages that can extend the areas where TightVNC can be helpful.

TightVNC is a project maintained by Constantin Kaplinsky. Many other individuals and companies participate in development, testing and support.

Here is a brief list of TightVNC features absent in the standard VNC.
1. File transfers in versions for Windows. You can updload files from your local machine to the TightVNC Server, and download files from the server to your computer.
2. Support for video mirror driver (Windows 2000 and above). TightVNC Server can use DFMirage mirror driver to detect screen updates and grab pixel data in a very efficient way, saving processor cycles for other applications.
3. Scaling of the remote desktop (viewer for Windows and Java viewer). You can view the remote desktop in whole on a screen of smaller size, or you can zoom in the picture to see the remote screen in more details.
4. Efficient "Tight" encoding with optional JPEG compression. New Tight encoding is optimized for slow and medium-speed connections and thus generates much less traffic as compared to traditional VNC encodings. Unlike other encodings, Tight encoding is configurable via compression levels and JPEG image quality setting.
5. Enhanced Web browser access. TightVNC includes a outstandingly improved Java viewer with full support for Tight encoding, 24-bit color mode, and more. The Java viewer applet can be accessed via built-in HTTP server like in the standard VNC.
6. Support for two passwords, full-control and read-only. The server allows or disallows remote keyboard and mouse events depending on which password was used for authentication.
7. Automatic SSH tunneling on Unix. The Unix version of TightVNC Viewer can tunnel connections via SSH automatically using local SSH/OpenSSH client installation.
8. And more. TightVNC includes a number of other improvements, performance optimizations and bugfixes, see change logs for more information.

Please Note:
TightVNC can work under Windows 7 and Windows Vista, but it cannot be used as a system service. This issue is under investigation.
