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.
* Java Viewer:
- Introducing new full-screen mode, with optional auto-scaling, auto-scrolling and a pop-up toolbar.
* Installer for Windows:
- Added new MSI installer properties, to automate pre-setting passwords in silent mode.
* Server for Windows:
- Fixed a problem with querying local users on incoming connections. TightVNC has a feature to let local user approve or reject incoming connections. If there was no user action within a pre-configured time limit, new connection will be either accepted or rejected automatically. Unfortunately, the timeout setting did not work correctly in previous version and that could result in infinite timeouts. That has been fixed.
- Fixed the Apply button in the Configuration window - it stayed disabled on editing configuration settings.
* Viewer for Windows:
- Fixed authentication handling in RFB protocol version 3.7. This should resolve connectivity problems with Ubuntu systems and Vino servers.
- Fixed hang-up on changing language or keyboard layout. To fix this problem, Windows message handling has been re-designed completely.
- Fixed priority of preferred encodings. Previous version could work inefficiently with servers that do not support Tight encoding, because the viewer could choose uncompressed Raw encoding instead of well-compressed ZRLE.
- Eliminated 34-character limit on hostnames in the New Connection window.
- Using correct line ending characters in cross-platform clipboard transfers.
- Introduced a number of improvements and fixes in the user interface. That includes new commands in the toolbar and in the system menu, and architectural changes such as restoring the option to start new connections from the same Viewer instance.
- Adjusting viewer window size on remote desktop resizing.
- Other minor improvements and fixes.
* Source Code (Server and Viewer for Windows):
- Improved logging architecture. The changes will not be visible to end user, but developers will appreciate new logging system. There should be no more static methods and global log objects, so it will be easier to reuse separate components in third-party applications. Now all components work via a simple logging interface or can work without logging at all.
- Corrected build problems in various combinations of build configurations and platforms, in both Visual Studio 2008 and Visual Studio 2010.
