TightVNC is a free remote control software package derived from the popular VNC software. 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 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.
TightVNC provides these features which are otherwise absent in standard VNC:
- File transfers in versions for Windows.
- Support for video mirror driver (Windows 2000 and above).
- Scaling of the remote desktop (viewer for Windows and Java viewer).
- Efficient "Tight" encoding with optional JPEG compression.
- Enhanced Web browser access.
- Support for two passwords, full-control and read-only.
* Server and Viewer for Windows: Introducing new file transfer subsystem based on new protocol extensions. Multiple files and directories can be copied at once, directories are processed recursively. Data compression is used to speed-up copying. Files can be renamed or removed, new directories can be created. File sizes are not limited by 4 Gb any more.
* Server for Windows: Implemented new architecture which separates service code from the user interface. This enables service-mode operation under Windows Vista and Windows 7. Also, this fixes all known problems with multi-user features of modern Windows systems like Fast User Switching and Terminal Services.
* Server for Windows: Screen updates have become reliable. If something went wrong and the picture in the viewer is garbled, incomplete or outdated, it will be recovered in reasonable time. There should be no more hidden menus or destructive window movements. If fast update detection methods fail, full-screen polling will keep updates going.
* Server for Windows: Featuring new secure administrative interface. What was called "TightVNC tray icon" in previous versions is now a separate process which acts as a control interface to the TightVNC service. Control interface can be optionally protected with a password to make sure users cannot reconfigure or shut down the service unless they know the password (or have administrator privileges).
* Server for Windows: There should be no more confusion between "default settings" and "user settings". In TightVNC 2.0, there is only one service-mode configuration and it is not affected by any per-user settings. The "Configure..." menu item of the service always shows the effective configuration. From the other side, TightVNC Server can be started as an application, and in that case each user has his/her own configuration.
* Server for Windows: Featuring IP-based access control for incoming connections. Previous versions of TightVNC did allow similar IP filtering, but now everything is easily configurable. You can even test the rules on specific IP addresses, prior to applying new rules.
* Installer: TightVNC 2.0 distribution has been packaged with new installer. It's smarter and more efficient. It tries to prevent reboots whenever possible. It invites to set passwords so that TightVNC Server would be ready to work right at the moment of finishing the installation. From the other side, it can operate silently (when run with /S option in the command line). Finally, the complete self-installing TightVNC package (both server and viewer parts, and the uninstall tool) is only 550 kilobytes in size.
* Server and Viewer for Windows: Keyboard handling has been improved. Older versions of TightVNC had problems with passing characters that do not fit in the Latin-1 code space. TightVNC 2.0 adds full support for different national codepages and keyboard layouts.
