Details 1. *** Introduction ************************************************** VNC is a great and famous remote controle, multi-OS tool, created at the ATT Research Labs de Cambridge-http://www.uk.research.att.com/vnc This Ultr@VNC version is based on: - RealVNC 336 & 337 and includes: - Most of eSVNC 1.1.2 r2 functionnalities - Most of Vdacc-VNC functionnalities - Cursor handling code and Tight encoding from TightVNC - VNC QuickDesk toolbar code - And various code modifications coming from talented developpers. - Since v1.0.0 RC 12, Ultr@VNC FileTransfer can transfer whole Directories. For this it uses "zip32.dll" and "unzip32.dll" dll files and source code coming from the Info-Zip group. Please see at the end of this document (section 7.) for details about these dlls. - Since v1.0.0 RC 12, the viewer Toolbar looks professionnal, thanks to Lim Chee Aun (http://www.phoenity.com/) who has designed it. Ultr@VNC brings tons of functionnalities and high performances even over modem connections. ------------------------------------------------------------------------ Many thanks to all people who help us developping, testing, stabilizing, answering users questions and animating the forum and the mailing list ------------------------------------------------------------------------ 2. *** Features ***************************************************** * Supported Operating Systems: Win9x/Me/NT4/2000/XP/2003 * Auto configuration and Quick Options for easy connections. * Viewer Toolbar for a quick access to the main functions and greatly improved ergonomy. * High Speed. On W2000 and XP, Ultr@VNC can use an additional and optionnal Video Hook Driver (aka Mirror Driver) that dramatically improves performances and reduces CPU activity over LAN connections. So when the bandwidth is good - typically over a LAN - Ultr@VNC lets you work on a remote computer with an incredible 'real-time' feeling (hundreds of screen updates per second), just as if you were sitting in front of it. A WinVNC server under Win9x uses the standard hookdll in combination with ddi hooking to improve the updates handling. Ultr@VNC also features an ultra fast Fullscreen Polling mode without any additionnal driver. Whatever the connection speed, Ultr@VNC brings you optimal comfort. Note that this driver is distributed separatly from Ultr@VNC. * Embedded File Transfer with intuitive Graphical User Interface allowing for easy file copy between local and remote computers. It uses the current VNC connection and files are compressed during their transfer. File transfers can be asynchronous so screen updates can continue while a file is being transfered in background. The delta transfer mode allows to resume interrupted transfers. * MS Logon/NT security support. You can manage server access using MS Users, Domains and Groups. It also includes a logging feature where all actions are written to a log file. * Bandwidth Saving Strategies that provide optimal responsiveness over slow connections: Server Screen Scaling, Cache Management , Local Cursor handling, reduced colors modes (256, 64, 8, Grey scales). * Advanced JavaViewer featuring FileTransfer, MSLogon and reduced color modes. * Data Stream Modification Plugin System allowing any kind of operation on the data exchanged between client and server, from an external DLL (independant, not linked and not distributed with Ultr@VNC): additionnal rights checking, communication timing, data recording/persitence, encryption... it's up to the DLL developper. * Optionnal "always-on-top" Viewer Status Window dynamically displaying connection informations. * Various View Modes including Full-Screen, Scaled and Windowed. Full-Screen mode lets you see the remote screen on the entire screen of your display. Scaled Viewer mode lets you see the scaled remote screen in a window with a user defined size. Scaled Server mode generates less network traffic from server side and use a pixel blending algorithm to optimize the display. Fuzzy Mode combines Server and Viewer scaling to provide reasonable visual comfort and speed even over very slow connections. The Autoscaling mode scales the view so it fits the viewer screen. * Dynamic Single Window/Full Desktop view switching, from viewer side. * Server's Desktop resolution switching without disconnection. * Dynamic Mouse and Keyboard locking on remote server, from viewer side. * Server Screen Blanking, from viewer side * Embedded Client/Server Text Chat. * Possibility to send Ctrl-Alt-Del to the remote server (when WinVNC is run as a service), or any other special key. * Support for 32/24/16/8 bits colors. Both Ultr@VNC Viewer and Server are compatible with RealVNC, TightVNC, eSVNC, PalmVNC2 (with server scaling feature)... Ultr@VNC server can work as a Service under all supported operating systems, allowing remote user Logon/Logoff as well as Remote Shutdown. * Connectivity: Standard Viewer and HTTP JavaViewer connections over TCP/IP, as well as XDMCP direct X11 connection (still experimental). 3. *** List of included files **************************************** - readme.txt : This text file - License.txt : GNU General Public License.
