-- rev.2245: Printing update statistics on disconnect: number of FramebufferUpdate messages, counters of real and pseudo rectangles in framebuffer updates.
-- rev.2246: Printing more statistics on disconnect: average update rate, and rectangle counters per each encoder (Tight, ZRLE, Hextile, Raw, CopyRect, others).
-- rev.2252: Initial support for continuous updates.

-Implemented support for auto-scaling. To enable it, the "Scaling factor"
-parameter should be set to "auto". Auto-scaling tries to choose scaling
-factor such way that the whole remote framebuffer will fit on the local
-screen. Currently, auto-scaling is supported only when the remote desktop
-is shown in a separate frame (always true in application mode, and in
-applet mode with "Open new window" parameter set to "yes").

-Simple implementation of client-side scaling, controlled by new "Scaling
-Factor" parameter. This implementation provides low-quality scaling but
-is compatible with Java 1.1. Things to do next: (1) GUI for "Scaling
-Factor" parameter; (2) documentation for "Scaling Factor" parameter;
-(3) new scaling implementation based on Java 2D which would require
-Java 2 platform but hopefully would show much higher scaling quality.

-Settings "Raw pixel drawing: Fast/Reliable" and "CopyRect:

-sense in new drawing model.
-Currently drawing of solid-color areas is slow but this issue
-hopefully will be fixed in next versions.

- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
- Preamble
-
- The licenses for most software are designed to take away your
-freedom to share and change it. By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users. This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it. (Some other Free Software Foundation software is covered by
-the GNU Library General Public License instead.) You can apply it to
-your programs, too.
-
- When we speak of free software, we are referring to freedom, not
-price. Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
- To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
- For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have. You must make sure that they, too, receive or can get the
-source code. And you must show them these terms so they know their
-rights.
-
- We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
- Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software. If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
- Finally, any free program is threatened constantly by software
-patents. We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary. To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
- The precise terms and conditions for copying, distribution and
-modification follow.
-\f
- GNU GENERAL PUBLIC LICENSE
- TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
- 0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License. The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language. (Hereinafter, translation is included without limitation in
-the term "modification".) Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope. The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
- 1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
- 2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
- a) You must cause the modified files to carry prominent notices
- stating that you changed the files and the date of any change.
-
- b) You must cause any work that you distribute or publish, that in
- whole or in part contains or is derived from the Program or any
- part thereof, to be licensed as a whole at no charge to all third
- parties under the terms of this License.
-
- c) If the modified program normally reads commands interactively
- when run, you must cause it, when started running for such
- interactive use in the most ordinary way, to print or display an
- announcement including an appropriate copyright notice and a
- notice that there is no warranty (or else, saying that you provide
- a warranty) and that users may redistribute the program under
- these conditions, and telling the user how to view a copy of this
- License. (Exception: if the Program itself is interactive but
- does not normally print such an announcement, your work based on
- the Program is not required to print an announcement.)
-\f
-These requirements apply to the modified work as a whole. If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works. But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
- 3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
- a) Accompany it with the complete corresponding machine-readable
- source code, which must be distributed under the terms of Sections
- 1 and 2 above on a medium customarily used for software interchange; or,
-
- b) Accompany it with a written offer, valid for at least three
- years, to give any third party, for a charge no more than your
- cost of physically performing source distribution, a complete
- machine-readable copy of the corresponding source code, to be
- distributed under the terms of Sections 1 and 2 above on a medium
- customarily used for software interchange; or,
-
- c) Accompany it with the information you received as to the offer
- to distribute corresponding source code. (This alternative is
- allowed only for noncommercial distribution and only if you
- received the program in object code or executable form with such
- an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it. For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable. However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-\f
- 4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License. Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
- 5. You are not required to accept this License, since you have not
-signed it. However, nothing else grants you permission to modify or
-distribute the Program or its derivative works. These actions are
-prohibited by law if you do not accept this License. Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
- 6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions. You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
- 7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License. If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all. For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices. Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-\f
- 8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded. In such case, this License incorporates
-the limitation as if written in the body of this License.
-
- 9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time. Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number. If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation. If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
- 10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission. For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this. Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
- NO WARRANTY
-
- 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
- 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.
-
- END OF TERMS AND CONDITIONS
-\f
- Appendix: How to Apply These Terms to Your New Programs
-
- If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
- To do so, attach the following notices to the program. It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
- <one line to give the program's name and a brief idea of what it does.>
- Copyright (C) 19yy <name of author>
-
- This program is free software; you can redistribute it and/or modify
- it under the terms of the GNU General Public License as published by
- the Free Software Foundation; either version 2 of the License, or
- (at your option) any later version.
-
- This program is distributed in the hope that it will be useful,
- but WITHOUT ANY WARRANTY; without even the implied warranty of
- MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
- GNU General Public License for more details.
-
- You should have received a copy of the GNU General Public License
- along with this program; if not, write to the Free Software
- Foundation, Inc., 59 Temple Place - Suite 330, Boston, MA 02111-1307,
- USA.
-
-Also add information on how to contact you by electronic and paper mail.
-
-If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
- Gnomovision version 69, Copyright (C) 19yy name of author
- Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
- This is free software, and you are welcome to redistribute it
- under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License. Of course, the commands you use may
-be called something other than `show w' and `show c'; they could even be
-mouse-clicks or menu items--whatever suits your program.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the program, if
-necessary. Here is a sample; alter the names:
-
- Yoyodyne, Inc., hereby disclaims all copyright interest in the program
- `Gnomovision' (which makes passes at compilers) written by James Hacker.
-
- <signature of Ty Coon>, 1 April 1989
- Ty Coon, President of Vice
-
-This General Public License does not permit incorporating your program into
-proprietary programs. If your program is a subroutine library, you may
-consider it more useful to permit linking proprietary applications with the
-library. If this is what you want to do, use the GNU Library General
-Public License instead of this License.

-contains code from other sources. See the Acknowledgements section below, and
-the individual files for details of the conditions under which they are made
-available.
-
-
-Compiling from the sources
-==========================
-
-To compile all the .java files to .class files, simply do:
-
- % make all
-
-This will also generate a JAR (Java archive) file containing all the classes.
-Most JVM (Java Virtual Machine) implementations are able to use either a set
-of .class files, or the JAR archive.
-
-
-Installation
-============
-
-There are three basic ways to use TightVNC Java viewer:
-
- 1. Running applet as part of TightVNC server installation.
-
- Both the Unix and Windows versions of TightVNC servers include small
- built-in HTTP server which can serve Java viewer to Web clients. This
- enables easy Web access to the shared desktop without need to install
- any software on the client computer. Unix and Windows versions of
- TightVNC servers are different in the way they store the .class and .jar
- files: the Unix server (Xvnc) is able to serve any set of files present
- in a particular directory, while the Windows server (WinVNC) has all the
- .class and .jar files inside the WinVNC executable file. Therefore, for
- Xvnc, it's enough to copy the files into a correct directory, but for
- WinVNC, the server binaries should be rebuild if the built-in Java
- viewer should be updated.
-
- To install the Java viewer under Xvnc, copy all the .class files, the
- .jar file and the .vnc files to an installation directory (e.g.
- /usr/local/vnc/classes):
-
- cp *.class *.jar *.vnc /usr/local/vnc/classes
-
- Also, make sure that the vncserver script is configured to point to the
- installation directory (see the Xvnc manual page for the description of
- the -httpd command-line option).
-
- 2. Running applet hosted on a standalone Web server.
-
- Another possibility to use the Java viewer is to install it under a
- fully-functional HTTP server such as Apache or IIS. Obviously, this
- method requires running an HTTP server, and due to the Java security
- restrictions, it's also required that the server should be installed on
- the same machine which is running the TightVNC server. In this case,
- installation is simply copying the .class and .jar files into a
- directory that is under control of the HTTP server. Also, an HTML page
- should be created which will act as a the base document for the viewer
- applet (see an example named index.html in this distribution).
-
- NOTE: Provided index.html page is an example only. Before using that
- file, edit it with a text editor. See more information inside
- index.html.
-
- 3. Running the viewer as a standalone application.
-
- Finally, the Java viewer can be executed locally on the client machine,
- but this method requires installation of either JRE (Java Runtime
- Environment) or JDK (Java Development Kit). If all the .class files are
- in the current directory, the Java viewer can be executed like this,
- from the command line:
-
- java VncViewer HOST vnchost PORT 5900
-
- The parameters HOST and PORT are required, but there is a number of
- optional parameters as well (see the Parameters section below).
-
-Parameters
-==========
-
-TightVNC Java viewer supports a number of parameters allowing you to
-customize its behavior. Most parameters directly correspond to the settings
-found in the Options window. However, there are parameters that do not
-correspond to those settings. For such parameters, you can see a note "no GUI
-equivalent", in the documentation below.
-
-Parameters can be specified in one of the two ways, depending on how the Java
-viewer is used:
-
- 1. When the Java viewer is run as an applet (embedded within an HTML
- document), parameters should be specified in the <PARAM> HTML tags,
- within the appropriate <APPLET> section. Here is an example:
-
- <APPLET CODE=VncViewer.class ARCHIVE=VncViewer.jar WIDTH=400 HEIGHT=300>
- <PARAM NAME="PORT" VALUE=5901>
- <PARAM NAME="Scaling factor" VALUE=50>
- </APPLET>
-
- 2. When run as a standalone application, the Java viewer reads parameters
- from the command line. Command-line arguments should be specified in
- pairs -- first goes parameter name, then parameter value. Here is a
- command line example:
-
- java VncViewer HOST vnchost PORT 5901 "Scaling factor" 50
-
-Both parameter names and their values are case-insensitive. The only
-exception is the "PASSWORD" parameter, as VNC passwords are case-sensitive.
-
-Here is the complete list of parameters supported in TightVNC Java viewer:
-
---> "HOST" (no GUI equivalent)
-
- Value: host name or IP address of the VNC server.
- Default: in applet mode, the host from which the applet was loaded.
-
- This parameter tells the viewer which server to connect to. It's not
- needed in the applet mode, because default Java security policy allow
- connections from applets to the only one host anyway, and that is the
- host from which the applet was loaded. However, this parameter is
- required if the viewer is used as a standalone application.
-
---> "PORT" (no GUI equivalent)
-
- Value: TCP port number on the VNC server.
- Default: none.
-
- This parameter is required in all cases. Note that this port is not the
- one used for HTTP connection from the browser, it is the port used for
- RFB connection. Usually, VNC servers use ports 58xx for HTTP connections,
- and ports 59xx for RFB connections. Thus, most likely, this parameter
- should be set to something like 5900, 5901 etc.
-
---> "PASSWORD"
-
- Value: session password in plain text.
- Default: none, ask user.
-
- DO NOT EVER USE THIS PARAMETER, unless you really know what you are
- doing. It's extremely dangerous from the security point of view. When
- this parameter is set, the viewer won't ever ask for a password.
-
---> "ENCPASSWORD"
-
- Value: encrypted session password in hex-ascii.
- Default: none, ask user.
-
- The same as the "PASSWORD" parameter but DES-encrypted using a fixed key.
- Its value should be represented in hex-ascii e.g. "494015f9a35e8b22".
- This parameter has higher priority over the "PASSWORD" parameter. DO NOT
- EVER USE THIS PARAMETER, unless you really know what you are doing. It's
- extremely dangerous from the security point of view, and encryption does
- not actually help here since the decryption key is always known.
-
---> "Encoding"
-
- Values: "Auto", "Raw", "RRE", "CoRRE", "Hextile", "ZRLE", "Zlib", "Tight".
- Default: "Auto".
-
- The preferred encoding. If the value is "Auto", then the viewer will
- continuously estimate average network throughput and request encodings
- that are appropriate for current connection speed. "Hextile" is an
- encoding that was designed for fast networks, while "Tight" is better
- suited for low-bandwidth connections. From the other side, "Tight"
- decoder in the TightVNC Java viewer seems to be more efficient than
- "Hextile" decoder so it may be ok for fast networks too. "ZRLE" encoding
- is similar to "Tight", but it does not support JPEG compression and
- compression levels. Unlike "Tight" encoding, "ZRLE" is supported in
- recent versions of RealVNC products. Other encodings are not efficient
- and provided for compatibility reasons.
-
---> "Compression level"
-
- Values: "Default", "1", "2", "3", "4", "5", "6", "7", "8", "9".
- Default: "Default". ;-)
-
- Use specified compression level for "Tight" and "Zlib" encodings. Level 1
- uses minimum of CPU time on the server but achieves weak compression
- ratios. Level 9 offers best compression but may be slow in terms of CPU
- time consumption on the server side. Use high levels with very slow
- network connections, and low levels when working over higher-speed
- networks. The "Default" value means that the server's default compression
- level should be used.
-
---> "JPEG image quality"
-
- Values: "JPEG off", "0", "1", "2", "3", "4", "5", "6", "7", "8", "9".
- Default: "6".
-
- Use the specified image quality level in "Tight" encoding. Quality level
- 0 denotes bad image quality but very impressive compression ratios, while
- level 9 offers very good image quality at lower compression ratios. If
- the value is "JPEG off", the server will not use lossy JPEG compression
- in "Tight" encoding.
-
---> "Cursor shape updates"
-
- Values: "Enable", "Ignore", "Disable".
- Default: "Enable".
-
- Cursor shape updates is a protocol extension used to handle remote cursor
- movements locally on the client side, saving bandwidth and eliminating
- delays in mouse pointer movement. Note that current implementation of
- cursor shape updates does not allow a client to track mouse cursor
- position at the server side. This means that clients would not see mouse
- cursor movements if mouse was moved either locally on the server, or by
- another remote VNC client. Set this parameter to "Disable" if you always
- want to see real cursor position on the remote side. Setting this option
- to "Ignore" is similar to "Enable" but the remote cursor will not be
- visible at all. This can be a reasonable setting if you don't care about
- cursor shape and don't want to see two mouse cursors, one above another.
-
---> "Use CopyRect"
-
- Values: "Yes", "No".
- Default: "Yes".
-
- The "CopyRect" encoding saves bandwidth and drawing time when parts of
- the remote screen are moving around. Most likely, you don't want to
- change this setting.
-
---> "Restricted colors"
-
- Values: "Yes", "No".
- Default: "No".
-
- If set to "No", then 24-bit color format is used to represent pixel data.
- If set to "Yes", then only 8 bits are used to represent each pixel. 8-bit
- color format can save bandwidth, but colors may look very inaccurate.
-
---> "Mouse buttons 2 and 3"
-
- Values: "Normal", "Reversed".
- Default: "Normal".
-
- If set to "Reversed", then right mouse button (button 2) will act as it
- was middle mouse button (button 3), and vice versa.
-
---> "View only"
-
- Values: "Yes", "No".
- Default: "No".
-
- If set to "Yes", then all keyboard and mouse events in the desktop window
- will be silently ignored and will not be passed to the remote side.
-
---> "Scale remote cursor"
-
- Values: "No", "50%", "75%", "125%", "150%".
- Default: "No".
-
- If a percentage value is specified, the remote cursor is reduced
- or enlarged accordingly. Scaling takes place only when "View only"
- is set to "No", and "Cursor shape updates" is set to "Enable".
-
---> "Share desktop"
-
- Values: "Yes", "No".
- Default: "Yes".
-
- Share the connection with other clients on the same VNC server. The exact
- behaviour in each case depends on the server configuration.
-
---> "Open new window" (no GUI equivalent, applicable only in the applet mode)
-
- Values: "Yes", "No".
- Default: "No".
-
- Operate in a separate window. This makes possible resizing the desktop,
- and adds scroll bars when necessary. If the server supports variable
- desktop size, the window will resize automatically when remote desktop
- size changes.
-
---> "Scaling factor" (no GUI equivalent)
-
- Value: an integer in the range of [1..1000], or the string "auto".
- Default: "100".
-
- Scale local representation of the remote desktop. The value is
- interpreted as scaling factor in percents. The default value of 100%
- corresponds to the original framebuffer size. Values below 100 reduce
- image size, values above 100 enlarge the image proportionally. If the
- parameter is set to "auto", automatic scaling is performed. Auto-scaling
- tries to choose scaling factor such way that the whole remote framebuffer
- will fit on the local screen. Currently, auto-scaling is supported only
- when the remote desktop is shown in a separate frame (always true in the
- application mode, and also in the applet mode with "Open new window"
- parameter set to "yes").
-
---> "Show controls" (no GUI equivalent)
-
- Values: "Yes", "No".
- Default: "Yes".
-
- Set to "No" if you want to get rid of that button panel at the top.
-
---> "Offer relogin" (no GUI equivalent, not applicable in the applet mode)
-
- Values: "Yes", "No".
- Default: "Yes".
-
- If set to "No", the buttons "Login again" and "Close window" won't be
- shown on disconnects or after an error has occured.
-
---> "Show offline desktop" (no GUI equivalent)
-
- Values: "Yes", "No".
- Default: "No".
-
- If set to "Yes", the viewer would continue to display desktop even
- if the remote side has closed the connection. In this case, if the
- button panel is enabled, then the "Disconnect" button would be
- changed to "Hide desktop" after the connection is lost.
-
---> "Defer screen updates" (no GUI equivalent)
-
- Value: time in milliseconds.
- Default: "20".
-
- When updating the desktop contents after receiving an update from server,
- schedule repaint within the specified number of milliseconds. Small delay
- helps to coalesce several small updates into one drawing operation,
- improving CPU usage. Set this parameter to 0 to disable deferred updates.
-
---> "Defer cursor updates" (no GUI equivalent)
-
- Value: time in milliseconds.
- Default: "10".
-
- When updating the desktop after moving the mouse, schedule repaint within
- the specified number of milliseconds. This setting makes sense only when
- "Cursor shape updates" parameter is set to "Enable". Small delay helps to
- coalesce several small updates into one drawing operation, improving CPU
- usage. Set this parameter to 0 to disable deferred cursor updates.
-
---> "Defer update requests" (no GUI equivalent)
-
- Value: time in milliseconds.
- Default: "50".
-
- After processing an update received from server, wait for the specified
- number of milliseconds before requesting next screen update. Such delay
- will end immediately on every mouse or keyboard event if not in the "view
- only" mode. Small delay helps the server to coalesce several small
- updates into one framebuffer update, improving both bandwidth and CPU
- usage. Increasing the parameter value does not affect responsiveness on
- mouse and keyboard events, but causes delays in updating the screen when
- there is no mouse and keyboard activity on the client side.
-
---> "SocketFactory" (no GUI equivalent)
-
- Value: name of the class.
- Default: none.
-
- This option provides the way to define an alternate I/O implementation.
- The dynamically referenced class must implement a SocketFactory
- interface, and create a Socket, as configured by this parameter. See the
- source in SocketFactory.java.
-
-
-RECORDING VNC SESSIONS
-======================
-
-Current version of the TightVNC Java viewer is able to record VNC (RFB)
-sessions in files for later playback. The data format in saved session files
-is compatible with the rfbproxy program written by Tim Waugh. Most important
-thing about session recording is that it's supported only if Java security
-manager allows access to local filesystem. Typically, it would not work for
-unsigned applets. To use this feature, either use TightVNC Java viewer as a
-standalone application (Java Runtime Environment or Java Development Kit
-should be installed), or as a signed applet. The code checks if it's possible
-to support session recording, and if everything's fine, the new "Record"
-button should appear in the button panel. Pressing this button opens new
-window which controls session recording. The GUI is pretty self-explained.
-
-Other important facts about session recording:
-
---> All sessions are recorded in the 24-bit color format. If you use
- restricted colors (8-bit format), it will be temporarly switched to
- 24-bit mode during session recording.
-
---> All sessions are recorded with cursor shape updates turned off. This is
- necessary to represent remote cursor movements in recorded sessions.
-
---> Closing and re-opening the recording control window does not affect the
- recording. It's not necessary to keep that window open during recording a
- session.
-
---> Avoid using Zlib and ZRLE encodings when recording sessions. If you have
- started recording BEFORE opening a VNC session, then you are ok. But
- otherwise, all Zlib-encoded updates will be saved Raw-encoded (that is,
- without compression at all). The case with ZRLE is even worse -- ZRLE
- updates will not be saved at all, so the resulting session file may be
- corrupted. Zlib decoding depends on the pixel data received earlier, thus
- saving the data received from the server at an arbitrary moment is not
- sufficient to decompress it correctly. And there is no way to tell Zlib
- or ZRLE decoder to reset decompressor's state -- that's a limitation of
- these encoders. The viewer could re-compress raw pixel data again before
- saving Zlib-encoded sessions, but unfortunately Java API does not allow
- to flush zlib data streams making it impossible to save Zlib-encoded RFB
- pixel data without using native code.
-
---> Usually, Tight encoding is the most suitable one for session recording,
- but some of the issues described above for the Zlib encoding affect the
- Tight encoding as well. Unlike Zlib sessions, Tight-encoded sessions are
- always saved Tight-encoded, but the viewer has to re-compress parts of
- data to synchronize encoder's and decoder's zlib streams. And, due to
- Java zlib API limitations, zlib streams' states have to be reset on each
- compressed rectangle, causing compression ratios to be lower than in the
- original VNC session. If you want to achieve the best possible
- performance, turn recording on BEFORE connecting to the VNC server,
- otherwise CPU usage and compression ratios may be notably less efficient.

---> To refresh remote desktop in the view-only mode, press "r" or "R"
- on the keyboard.

-+--------------------------------------------------------------------+
-| This is a brief summary of changes introduced in each TightVNC |
-| release. For more details, please see ChangeLog files included |
-| in TightVNC source and binary archives. |
-+--------------------------------------------------------------------+
-
-* TightVNC 1.3.9
-
- - All platforms: Added support for the standard RFB protocol version
- 3.8 with TightVNC extensions.
-
- - All platforms: Made "host:port" parsing maximally compatible with
- VNC4. Interpreting a number in host names like somehost:5900 as an
- actual port number if it's not in the range [0..99].
-
- - Windows Server: Various user interface enhancements - changes in
- GUI labels, tray icon with a red border when incoming connections
- are not possible for any reason, more information in the tray icon
- tip, smarter logic in displaying the Properties dialog, and more.
-
- - Windows Server: Fixed a problem introduced in TightVNC 1.3.8 -
- default passwords were not respected if user passwords were not
- set.
-
- - Windows Server: Slightly improved handling of passwords. One of
- the notable changes is that now it's enough to enter a view-only
- password without providing primary password.
-
- - Windows Server: Fixed problems with running WinVNC service and
- Terminal Services. When a Remote Desktop (RDP) client connected to
- the console, WinVNC showed black screen and did not restore normal
- operations even on disconnection of that RDP client. Now, we
- always share the console correctly, and disable simultaneous RDP
- and VNC sessions. The changes were ported from VNC 4.1.2.
-
- - Windows Server: Better way of simulating Ctrl+Alt+Del. There are
- reports that this solves the problem with greyed username and
- password fields on Windows 2003 Server (bug #887617).
-
- - Windows Server: Bugfix for the bug #1109102: attempt to restart
- the machine remotely via TightVNC led to disconnect if there was
- some non-saved data, and further connections were rejected.
-
- - Windows Viewer: Multiple selection now works in file transfers,
- thanks to developers at Novell and personally Rohit Kumar.
-
- - Windows Viewer: The viewer terminated silently when the server
- dropped connection right after accepting it. Now we report such
- errors.
-
- - Windows version source archive: Included project files for
- compiling with Visual C++ 2005 Express Edition. Also, all required
- libraries are now included within the source distribution.
-
- - Unix Server: Applied patches from Debian Linux that port Xvnc to
- x86_64 platform (tightvnc-1.2.9-amd64support.p and
- tightvnc-1.3_alpha7-x86_64.patch), thanks to Quanah Gibson-Mount.
-
- - Java viewer: Implemented scaling, either with a fixed scaling
- factor or automatic. If Java 2D API is available (Java 1.2 and
- higher), then high-quality scaling is used. From the other side,
- the viewer remains compatible with Java 1.1 where it would simply
- use scaling with much decreased image quality. Scaling can be
- enabled with new "Scaling Factor" parameter but cannot be
- controlled from the GUI yet.
-
- - Java viewer: Added support for ZRLE encoding.
-
- - Java viewer: Disabled focus traversal keys under JVMs 1.4 and
- higher. This fixes the problem with not sending Tab key events to
- the VNC server.
-
- - Java viewer: Fixed wrong pixel format interpretation at decoding
- RichCursor pseudo-encoding (local cursor could be rendered in
- wrong colors).
-
- - Other improvements and bugfixes, see ChangeLog files within the
- distribution for more details.
-
-* TightVNC 1.3.8, release candidate version
-
- - Win32 server: Fixed major problem with disconnecting clients on
- screen locking, user logoff and logon, in the service mode.
-
- - Win32 server: Added support for DFMirage driver direct screen
- access mode (from DemoForge LLC).
-
- - Win32 server: Added support for multiple monitors (from DemoForge
- LLC).
-
- - Win32 server: Improved layout and functionality of the Properties
- dialog.
-
- - Win32 server: More accurate password handling - now the server
- code tries to distinguish between "empty" and "unset" passwords
- better.
-
- - Win32 server: New -shareall, -shareprimary and -sharearea
- command-line options, working similarly to the -sharewindow
- option.
-
- - Win32 server: Fixed problems with restoring desktop wallpaper.
-
- - Win32 viewer: Fixed bug with not enabling JPEG compression by
- default.
-
- - Win32 viewer: Fixed bug with not setting proper size of the viewer
- window.
-
- - Unix server: Port numbers are now calculated modulo 65536 with
- vncviewer's -listen option. That makes it possible to listen on
- TCP ports under 5900.
-
- - Java viewer: Automatic encoding selection based on measuring
- current network throughput.
-
- - Other improvements and bugfixes, see ChangeLog files within the
- distribution for more details.
-
-* TightVNC 1.3dev7, release candidate version
-
- - Win32 server: Fixed the problem with "olemainthreadwndname not
- responding" in service mode under Windows NT 4.0. Under that OS,
- the TightVNC service could hang on logoff.
-
- - Win32 server: Removed the code for "desktop optimizations" that
- was rather harmful than useful. Hopefully, this should fix
- problems with crashing Delphi applications. Also this should
- prevent settings like font smoothing always set to true on
- disconnect.
-
- - Win32 server: Fixed the issue with port number edit boxes that
- were labeled incorrectly in the Properties dialog.
-
- - Win32 server: Disallowing clipboard transfers in view-only mode.
-
- - Win32 server: Fixed the problem with carriage return/linefeed
- conversion of clipboard data.
-
- - Win32 server: Fixed the problem with wallpaper being removed only
- after completing the initial screen transmission.
-
- - Win32 server: Minor improvements in the File Transfers dialog.
-
- - Win32 server: More context help messages in Properties and File
- Transfers dialogs.
-
- - Unix server: Fixed a serious bug with sending cursor updates when
- there was no FrameBufferUpdateRequest from that client.
-
- - Unix server: Fixed problems with building Xvnc on modern linux
- distributions, such as Fedora Core 3.
-
- - Unix server: Disallowing clipboard transfers for view-only
- clients.
-
- - Other improvements and bugfixes, see ChangeLog files within the
- distribution for more details.
-
-* TightVNC 1.3dev6, Win32 release candidate version
-
- - Win32 server: Improved layout of the Properties dialog, added
- context help for every option. Also, current mirror driver status
- is shown in the Hooks tab.
-
- - Win32 server: Implemented new checkbox "Enable applet params in
- URLs" corresponding to EnableURLParams registry setting.
-
- - Win32 server: The option "Don't use mirror display driver even if
- available" is now functional.
-
- - Win32 server: New option "Blank screen on client connections".
- When set and new client connects, the server's monitor is forced
- to go to power saving mode.
-
- - Win32 server: Fixed bugs with saving certain settings in the
- registry, and bugs with setting default values when the registry
- is not writable.
-
- - Win32 server: Fixed a problem with one-pixel mouse offset.
-
- - Win32 server: Fixed problems with inter-thread locking, this
- should solve "Unhandled message type received" problems.
-
- - Win32 server: Fixed a problem with the setting "Block remote input
- on local activity", it was not working with DLL hooks disabled.
-
- - Win32 server: Fixed various problems with file transfer
- implementation. Error handling was improved, the C: drive bug
- under Win98/Me seems to be solved.
-
- - Win32 viewer: New "Auto" scaling mode. In this mode, the viewer
- scales remote desktop to fit local window or screen size. If the
- window size is changed, the scaling factor is adjusted
- automatically.
-
- - Win32 viewer: Now the viewer checks server's capabilities and does
- not ever use non-standard protocol messages not supported by the
- server. This change affects file transfers only, as other features
- do not use non-standard protocol messages..
-
- - Java viewer: New "scale remote cursor" option has been added. It
- allows to reduce or enlarge cursor image in the full-control mode.
-
- - Java viewer: A cursor repaint problem has been fixed.
-
- - Other improvements and bugfixes, see ChangeLog files within the
- distribution for more details.
-
-* TightVNC 1.3dev5, development version
-
- - Win32 server: Support for the "DFMirage" mirror video driver has
- been added (the driver itself will be available separately). Using
- the mirror driver greatly increases the speed and reliability of
- updates, and also desreases CPU utilization on the server.
-
- - Win32 server: New polling algorithm has been implemented. It's
- similar to that found in x0rfbserver. New algorithm uses minimum
- CPU time when there are no changes on the screen, and detects
- major changes very quickly, resulting in greatly improved
- responsiveness on the client side.
-
- - Win32 server: Improved methods for filtering screen changes that
- actually do not change anything. New algorithm not only works
- faster, but it also detects changes much more accurately, leaving
- less work to encoders.
-
- - Win32 viewer: A special mode for Unix users has been implemented:
- when ScrollLock is on, the viewer will send Meta on pressing Alt
- keys.
-
- - Win32 server: Fixed a problem with view-only clients that were
- enabled full control on just opening the Properties dialog of the
- server.
-
- - Win32 server: It should not ever hang any more on changing ports
- or the LoopbackOnly setting.
-
- - Win32 server: DisableTrayIcon and RemoveWallpaper settings are
- working again.
-
- - Win32 server: The problem with not saving Query Settings has been
- fixed.
-
- - Win32 server: The polling mode "on event received only" has been
- fixed - it did not work correctly in previous version.
-
- - Win32 server: Fixed a number of issues with mouse handling,
- including that annoying problem with pointer jumping on slow
- connections.
-
- - Win32 server: Applied a bugfix from HorizonLive solving the
- problem with crashes or incorrect operation after color depth
- changes on the server's desktop.
-
- - Win32 viewer: It does not crash any more on entering long
- passwords in the authentication window.
-
- - Win32 viewer: Positioning and resizing logic of the viewer window
- has been improved.
-
- - Win32 viewer: Now the viewer chooses more reasonable file names
- for saved .vnc sessions.
-
- - Win32 viewer: In the full-screen mode, the viewer allows other
- windows to be shown above the remote desktop. This makes hotkeys
- such as Shift-Ctrl-Alt-O useful in the full-screen mode.
-
- - Unix version: A number of bugfixes -- copying clipboard to
- non-authenticated clients in Xvnc, delayed cursor shape updates in
- Xvnc, and crashing on switching between KDE virtual desktops in
- vncviewer.
-
- - Unix viewer: Support for the new -autopass option has been added,
- a patch from Ki NETWORKS, Inc.
-
- - Other changes, see ChangeLog files within the distribution for
- more details.
-
-* TightVNC 1.3dev4, development version
-
- - Featuring updated Unix version and Java viewer, supporting RFB
- protocol version 3.7, with or without TightVNC protocol
- extensions. Version 3.3 of the protocol is supported as well.
-
- - Win32 version: Built-in Java viewer was absent in the previous
- development version; now it's available again.
-
- - Win32 version: Now the server does not crash on remote
- Ctrl-Alt-Del events, and on changing display modes.
-
- - Win32 version: A problem with reinstalling the service has been
- fixed (WinVNC -reinstall command-line option). In previous
- versions, reinstalling the service could fail if a user did not
- close "Service unregistered" message box within a few seconds.
-
- - Win32 version: Now the server does not hang on selecting equal RFB
- and HTTP port numbers. A warning is shown instead.
-
- - Win32 version: The server does not hang on toggling loopback
- connection options, and on changing port/display numbers.
-
- - Win32 version: WinVNC does not crash on choosing "Kill All
- Clients" during file download.
-
- - Win32 version: CopyRect handling in the server has been fixed, the
- CopyRect encoding is enabled again.
-
- - Win32 version: The Advanced Properties dialog of the server has
- been removed. The controls of that dialog has been moved to tabs
- in the Properties dialog.
-
- - Win32 version: Context help in the server's Properties dialog has
- been implemented (although not all descriptions are ready yet).
-
- - Unix viewer: Fixed a bug with the viewer crashing on selecting
- text in Xvnc, and then choosing F8 / Clipboard: local -> remote,
- twice.
-
- - There was some progress on supporting pluggable encryption and
- authentication methods, in both Win32 and Unix versions, and in
- the Java viewer.
-
- - Other changes, see ChangeLog files within the distribution for
- more details.
-
-----------------------------------------------------------------------
-
-* TightVNC 1.3dev3, Win32 development (unstable) version
-
- - All features and fixes from 1.2.9 and 1.3dev1 versions included.
-
- - Improved GUI of the viewer featuring toolbar, hotkeys, pre-set
- connection profiles, more configuration options, context help in
- dialogs, and more. Finally, the viewer remembers all
- per-connection and global settings in the registry.
-
- - File transfers between viewer and server machines.
-
- - Support for RFB protocol version 3.7, with TightVNC extensions.
-
- - A possibility to turn off hooking via VNCHooks.dll in WinVNC while
- full screen polling is in use.
-
- - Other changes, see ChangeLog files within the distribution for
- more details.
-
-----------------------------------------------------------------------
-
-* TightVNC 1.2.9
-
- - Win32 version: Major security-related bug in the server has been
- fixed -- handling of the "QueryAllowNoPass" option was seriously
- broken. Together with fixing this bug, the whole authentication
- logic in the server code has been redesigned.
-
- - Win32 version: Now the HKEY_CURRENT_USER registry hive is being
- closed properly on restoring display settings, on disconnect. This
- change should solve the problem with unloading the registry on
- logout, when WinVNC is running as a service.
-
- - Win32 version: Problems with "QuerySetting" and "QueryTimeout"
- options have been fixed -- the settings could be copied from user
- configuration to default settings without user's intention.
-
- - Win32 version: A long-standing bug has been fixed -- the logic to
- handle retries after authentication failures was flawed, and used
- to delete the same object twice under certain conditions.
-
- - Win32 version: Now it's possible to specify port numbers with the
- winvnc -connect option, using the "host::port" format. Also,
- providing a -connect option without arguments now brings up the
- "Add New Client" dialog.
-
- - Unix version: New "Request refresh" button has been implemented in
- the viewer's F8 popup menu.
-
- - Unix version: Xvnc compilation fixes for HP-UX and MacOS X have
- been applied, from Ki NETWORKS, Inc.
-
- - Unix version: New vncpasswd -f command-line option has been
- implemented. It allows providing passwords on stdin and writes
- encrypted passwords to stdout. In addition, the password file name
- "-" now denotes stdout. Finally, a buffer overflow has been fixed
- in vncpasswd -- it could be caused by a long file name in the
- command line.
-
- - Unix version: A patch to fix input focus problems in the X11
- viewer has been applied, from Greg Breland.
-
- - Unix version: A patch fixing Xvnc crashes on Sparc has been
- applied, from the RealVNC distribution.
-
- - Unix version: A problem with incorrect port interpretation has
- been fixed, in the vncviewer's -tunnel option handling. Thanks to
- Clark Sessions.
-
- - Java viewer: A modification from Bernd Krueger-Knauber has been
- accepted, to pass through X keysyms for foreign currencies.
-
- - Java viewer: The problem with initial keyboard focus not set to
- the desktop on some JVMs has been fixed.
-
- - Other minor improvements and bugfixes.
-
-----------------------------------------------------------------------
-
-* TightVNC 1.2.8
-
- - Unix and Win32 versions: Support for a separate view-only password
- has been implemented. Now the servers support two passwords -- one
- to allow full control, another to restrict remote keyboard and
- mouse input.
-
- - Win32 version: The password reset problem has been solved. In
- versions starting from 1.2.4, the password could get changed in
- the registry on opening Properties dialog and just hitting the OK
- button.
-
- - Win32 version: New "-reload" command-line option has been
- implemented in Win32 server. It forces the running instance to
- reload the registry settings.
-
- - Win32 version: "RemoveWallpaper" and "LockSetting" options have
- been made configurable in the Properties dialog; the code has been
- ported from RealVNC 3.3.6.
-
- - Win32 version: Support for "AllowEditClients" registry setting has
- been ported from RealVNC 3.3.6.
-
- - Unix version: New "-x11cursor" option has been implemented in
- vncviewer; a patch from Peter Astrand. This option allows using a
- real X11 cursor with X11-style cursor shape updates, disables the
- dot cursor, and disables cursor position updates in non-fullscreen
- mode.
-
- - Unix version: New "RunCommand" command to customize the X11
- vncviewer popup menu has been implemented; a patch from Peter
- Astrand.
-
- - Unix version: Several patches from Debian Linux have been applied.
- This should fix a number of bugs and improve building on some
- platforms supported by Debian Linux.
-
- - Unix version: A problem with Xvnc eating all CPU time after xfs
- restarts has been fixed; a patch from Martin Koegler.
-
- - Other minor improvements and bugfixes.
-
-----------------------------------------------------------------------
-
-* TightVNC 1.2.7
-
- - Unix and Win32 versions, Java viewer: The most significant problem
- with local cursor handling has been solved -- now clients can see
- remote cursor movements performed on the server or by another
- client. New PointerPos encoding and cursor shape updates both
- minimize bandwidth requirements and greatly improve responsiveness
- of the mouse pointer, while still allow to track correct pointer
- position in all situations.
-
- - Unix and Win32 versions: In all the places where display numbers
- had to be used, now it's easy to use port numbers as well. The
- viewers now allow to use new "hostname::port" syntax, in addition
- to the traditional "hostname:display" format. The same new syntax
- can be used in the "Add new client" dialog of Win32 server. In the
- server, now it's equally easy to set display and port numbers.
- Besides that, HTTP and RFB port numbers can be set individually.
-
- - Unix and Win32 versions: In servers, decreased JPEG quality
- factors for low quality levels. This improves bandwidth usage
- while the image quality remains satisfactory in most cases. In
- clients, JPEG compression is now enabled by default, because
- usually it's a reasonable choice. To prevent viewers from
- requesting JPEG compression, new -nojpeg option can be used.
-
- - Unix and Win32 versions: Improved installer under Windows, better
- RPMs for Linux.
-
- - Win32 version: Major enhancements in layout and functionality of
- the dialog boxes.
-
- - Win32 version: New keyboard handling code has been ported from
- RealVNC 3.3.6. This should solve all the issues with arrow keys
- acting as numbers in console windows, and shift+arrows not working
- under Win2k.
-
- - Win32 version: Adopted WinVNC -reinstall option from RealVNC
- 3.3.5, together with a number of other changes in different
- places. The viewer now accepts a port number after the -listen
- command-line option, an improvement from RealVNC 3.3.6.
-
- - Win32 version: Eliminated high CPU usage on the server before
- sending cursor shape updates.
-
- - Unix version: Bugfix for Xvnc's -localhost and -interface options
- that were broken on many systems, thanks to Luke Mewburn for the
- bugfix. Xvnc -version command-line option is now supported.
-
- - Tight encoding is now documented in rfbproto.h files within source
- archives.
-
- - Java viewer: Implemented new buttons "Login again" and "Close
- window" near the disconnect or error messages in the applet mode,
- and introduced new "Offer Relogin" parameter to control this
- improvement. Thanks to Peter Astrand for the initial version of
- the "Login again" patch.
-
- - Java viewer: Support for connections via HTTP proxies using HTTP
- CONNECT method. This will not work in the applet mode, due to Java
- security restrictions.
-
- - Java viewer: Extra .vnc files have been removed, having just
- index.vnc should be enough. Also, an example HTML page has been
- prepared, to simplify installation under a standalone Web server.
-
- - Java viewer: Added a MANIFEST to the JAR archive, to allow easy
- execution of the JAR file, using java -jar command-line option.
-
- - Other minor improvements and bugfixes.
-
-----------------------------------------------------------------------
-
-* TightVNC 1.3dev1, Win32 development (unstable) version
-
- - Implemented partial screen sharing. Any single window or any
- rectangular screen area can be shared instead of the whole screen.
- The position and dimensions of the shared screen area can be
- changed dynamically, and client windows will adjust their
- dimensions on the fly. The user interface to choose shared screen
- area is very intuitive and easy to use.
-
- - Screen resolution changes won't cause WinVNC to disconnect clients
- any more (but changes in screen color format still result in
- disconnects, this will be fixed later).
-
- - It's possible to make WinVNC ignore remote inputs when local mouse
- or keyboard is in use. Remote events will be re-enabled after a
- specified timeout (3 seconds by default).
-
- - There may be other changes I forgot to mention. :-)
-
-----------------------------------------------------------------------
-
-* TightVNC 1.2.6
-
- - Win32 version: In this version, when WinVNC binds to a local TCP
- port, it does not try to check several times if the port is in
- use. It just re-uses the port if the display number is not set to
- "Auto". One visible effect of this change is that the delay
- between starting up and showing the icon is greatly reduced.
-
- - Unix version: Fixed the bug which caused the vncserver script to
- fail when the XAUTHORITY environment variable was not set.
-
- - Unix version: Fixed the bug which prevented the vncpasswd utility
- from setting correct permissons on the passwd file.
-
- - Unix version: Fixed a repeated challenge replay attack
- vulnerability, bugtraq id 5296.
-
- - Unix version: Added files to simplify building of Linux RPMs,
- thanks to Peter Astrand.
-
- - Unix version: Improved scrolling in the full-screen mode, modified
- patch from Ville Herva.
-
- - Minor cleanups.
-
-----------------------------------------------------------------------
-
-* TightVNC 1.2.5
-
- - Win32 version: Fixed a problem in the I/O subsystem that was
- introduced in TightVNC 1.2.2 and was causing major slowdown in
- communication with clients.
-
- - Win32 version: Enabled remote upgrade in the installation script.
- Also, the installer will install a copy of the TightVNC Web site,
- and will create shortcuts to most important documentation pages.
-
- - Win32 version: Implemented new feature to specify applet
- parameters in URL requests being sent to the built-in HTTP server.
- Added support for new "EnableURLParams" registry setting which can
- be used to enable this feature.
-
- - Win32 version: Added support for the NewFBSize pseudo-encoding
- allowing to change framebuffer geometry on the fly on server's
- request.
-
- - Win32 version: Included "solution" and "project" files for MS
- Visual Studio 7, from Andrew van der Stock, applied a set of minor
- fixes to suppress compilation warnings under MS Visual Studio 7.
-
- - Win32 version: The viewer now tries to preserve the size and
- position of the desktop window after applying new connection
- options.
-
- - Unix version: Implemented new feature to specify applet parameters
- in URL requests being sent to the built-in HTTP server. Added
- support for new $PARAMS variable in .vnc HTML templates.
-
- - Unix version: Added the possibility to keep users' vnc directories
- under /tmp, as suggested by Ivan Popov. This mode can be enabled
- by editing the $vncUserDir variable in the vncserver script. Also,
- new -t option has been implemented in the vncpasswd utility which
- allows to change VNC password files under /tmp.
-
- - Unix version: Applied Xvnc -viewonly patch from Ehud Karni.
-
- - Unix version: Applied Linux/PowerPC Xvnc fix from Peter A. Castro.
-
- - Unix version: Bug fixed: Xvnc failed to reset compression level
- and JPEG image quality on reading lists of encodings supported by
- clients.
-
- - Unix version: Made the viewer handle XCursor encoding operating on
- the framebuffer instead of setting new cursors directly in X.
-
- - Unix version: Applied a number of porting fixes from Ki Networks,
- Inc.
-
- - Java viewer: Added new feature allowing to save RFB sessions in
- FBS files compatible with rfbproxy. This feature works only if JVM
- security manager allows access to the local filesystem, which is
- usually true only when the viewer is used as a standalone
- application or if the viewer applet is cryptographically signed.
- New "Record" button will appear in the button panel if this
- feature is enabled.
-
- - Java viewer: Added new "ENCPASSWORD" parameter, modified patch
- from Peter Astrand.
-
- - Java viewer: Applied patch from Peter Astrand to fix problems with
- Swedish keys and broken JVMs.
-
- - Other minor fixes and cleanups.
-
-----------------------------------------------------------------------
-
-* TightVNC 1.2.4
-
- - Win32 version: WinVNC crashes on reporting zero statistics were
- fixed. This should eliminate crashes when using x2vnc and win2vnc
- client programs.
-
- - Win32 version: a problem with listening viewer was fixed.
- Initiating multiple non-shared connections could crash the viewer
- application.
-
- - Win32 version: real passwords are never placed into the password
- text control in the WinVNC Properties dialog any more. This should
- prevent grabbing plain-text passwords from that text control.
-
- - Win32 version: logging on errors was improved to provide better
- diagnosis for errors, especially for those causing the message
- "Connection closed" right after authentication.
-
- - Win32 version: handling of log files was improved. Now WinVNC
- should be able to save backup copies of log files under
- Win95/98/Me. Also, all log files are now written in MS-DOS/Windows
- text format instead of the Unix one.
-
- - Win32 version: a problem with reporting error messages in the
- listening viewer was fixed.
-
- - Win32 version: reporting incorrect statistics in the Tight encoder
- was fixed.
-
- - Win32 version: HTML pages and templates for the built-in HTTP
- server were improved.
-
- - Unix version: applied patch from Ki Networks, Inc. solving build
- problems on a number of commercial Unix systems, and fixing a
- number of minor bugs and typos.
-
- - Unix version: added a possibility to denote standard input with
- the "-" file name instead of a real password file name.
-
- - Unix version: fixed a bug causing vncpasswd utility work
- incorrectly when a file name argument was given in the command
- line.
-
- - Unix version: applied patch to solve keyboard focus problems in
- the full-screen vncviewer, from Peter Astrand. The patch does not
- seem to solve all the issues, but definitely makes things better.
- New grabKeyboard resource was added to control full-screen mode
- behavior.
-
- - Java viewer: new "Show Offline Desktop" parameter was added to
- make the desktop still visible even after the remote side has
- closed connection.
-
- - Java viewer: error messages were made much more meaningful.
-
- - Java viewer: keyboard focus problems were fixed. This should
- prevent opening new windows (e.g. Options or Clipboard) behind the
- active authenticator or desktop window.
-
- - Java viewer: now "R"/"r" keys can be used to request screen
- updates in view-only mode.
-
- - Java viewer: applied patch from Peter Astrand to fix problems with
- Swedish keys and broken JVMs.
-
- - Other minor fixes and cleanups.
-
-----------------------------------------------------------------------
-
-* TightVNC 1.2.3
-
- - Unix and Win32 versions: zlib library was updated to the most
- recent version (1.1.4) where a potential security issue was fixed.
-
- - Unix and Win32 versions: fixed blocking I/O problems in built-in
- HTTP servers. Older versions had to wait while one client finishes
- his transaction, only then they served new client connections,
- thus making easy denial-of-service attacks possible.
-
- - Unix and Win32 versions: updated built-in Java viewer, see details
- below.
-
- - Win32 version: Added support for mouse wheel events. Wheel mouse
- support is fully compatible and interoperable with Unix version
- where this feature was available for a long time.
-
- - Win32 version (WinVNC): The -connect command-line option now
- accepts a display number after a hostname.
-
- - Win32 version: Creating associations for .vnc files in the
- installer.
-
- - Java viewer was GREATLY improved: the code was converted to Java
- 1.1, painting techniques were re-designed completely (now the
- viewer should work in MacOS), several new parameters were added,
- all parameters were documented in the README file. Most important
- new features include: support for 24-bit colors, JPEG support in
- Tight encoding, RFB Bell message support, new "Refresh" button, a
- possibility to operate in a separate scrollable window, dynamic
- view-only mode. Many more changes were introduces, see the
- ChangeLog for more information. Please note that new Java viewer
- class names were changed, e.g. vncviewer.jar file has become
- VncViewer.jar etc.
-
- - Unix version: a number of changes in the vncserver script, e.g.
- the default color depth is now 24, extra delay after Xvnc startup
- removed, font path is now configurable in the beginning of the
- script, and more.
-
- - Unix version: zlib library was removed from the core X sources.
- Instead, both vncviewer and Xvnc now can use either system zlib
- and JPEG libraries, or ones packaged within TightVNC source
- archive in the lib/ directory. Unix sources are distributed in two
- versions: one with these libraries for those who don't have them
- installed in the system, and another version without libraries,
- copied directly from CVS, for those who do have zlib and/or JPEG
- libraries installed. In the former case, build procedure would
- include additional "make libs" step. System libraries will be
- linked dynamically, libraries included in the source archive will
- be linked in statically.
-
- - Unix version now includes comprehensive manual pages for
- vncviewer, vncserver, Xvnc, vncconnect and vncpasswd programs. The
- vncinstall script in the source distribution now accepts one more
- parameter allowing to specify where to install manual pages.
-
- - Unix version (Xvnc): a number of patches from Red Hat Linux vnc
- package were incorporated into the TightVNC codebase. This adds
- support for more architectures including s390 and s390x, adds a
- possibility to use tcp_wrappers for Xvnc access control.
-
- - Unix version (Xvnc): several bugfixes, e.g. applied patch to fix
- crash in the code dealing with font server; fixed word alignment
- problem in raw encoder experienced by Sparc users.
-
- - Unix version is no more distributed as patches to a standard VNC
- release. This is because patches cannot handle changes in binary
- files and handle file removals very inefficiently.
-
- - Other minor fixes and cleanups.
-
-----------------------------------------------------------------------
-
-* TightVNC 1.2.2
-
- - Win32 server: long-standing Win9x resource consumption problem has
- been fixed. Now the server thread does not use blocking I/O, and
- therefore is always ready to process messages from the VNCHooks
- DLL.
-
- - Win32 server: now built-in HTTP daemon may be enabled and disabled
- interactively from the Advanced Preferences dialog (this setting
- is saved in new "EnableHTTPDaemon" registry key).
-
- - Win32 server: changes in layout and text of the Advanced
- Preferences dialog.
-
- - Xvnc: Minor bugfix which should prevent potential dereference of a
- NULL pointer.
-
- - Unix viewer: Now viewer window would be raised on beep (bell)
- event, unless new -noraiseonbeep option is provided in the command
- line or "raiseOnBeep" resource set to False.
-
- - One more packaging option for the Unix source: ready to build
- archive with Zlib and JPEG libraries inside.
-
- - Other minor fixes and cleanups.
-
-----------------------------------------------------------------------
-
-* TightVNC 1.2.1
-
- - Win32 server: added support for reverse connections on ports other
- than 5500, modified patch from Steve Kann.
-
- - Win32 viewer: added support for new command-line options:
- -noshared and -encoding XXX.
-
- - Bugfixes in Win32 viewer: changes in exception handling eliminate
- Borland C++ compilation problems causing application crashes on
- repetitive connections, notably in the listen mode. Also, now
- warning exceptions causing disconnects are reported to user,
- except for the case when a user has closed the viewer window.
-
- - Better packaging in Win32 version: self-installing package is
- available, vncviewer now shows correct icon image.
-
- - Unix vncviewer: Default tunneling command template has been
- changed, to allow tunneled connections to hosts where only
- loopback VNC connections are enabled. New -via <GATEWAY>
- command-line option provides enhanced tunneling functionality, now
- one can make vncviewer tunnel connections to a VNC host via third
- machine acting as a gateway.
-
- - Java viewer: Addition of new parameters PASSWORD, "Show Controls",
- and "View Only", modified patch from Steve Kann.
-
-----------------------------------------------------------------------
-
-* TightVNC 1.2.0
-
- - Tight encoding is now configurable and can operate at different
- compression levels where low compression levels are very fast in
- terms of CPU usage. New "-compresslevel N" option implemented in
- vncviewer to set compression levels for Tight encoding (1 - fast,
- 9 - best).
-
- - Enhanced techniques to split large rectangles in Tight encoder;
- now it tries to find large solid-color areas and send them in
- separate rectangles.
-
- - Lossy JPEG compression in Tight encoding has been implemented, new
- "-quality N" vncviewer option should be used to enable this
- feature (0 - low image quality and best compression, 9 - best
- image quality). JPEG compression is used only for screen areas
- that seem to be suitable for JPEG compression (although algorithms
- to detect such areas are not perfect, of course).
-
- - New "XCursor" and "RichCursor" encodings implemented. They are
- used to transmit cursor shape updates from server to clients
- ("local cursor" feature requested by many users). Mouse movement
- no longer causes framebuffer updates to happen, vncviewer
- processes mouse locally when this feature is active. New
- -nocursorshape vncviewer option turns this feature off.
-
- - A number of recent changes from both TridiaVNC and AT&T's releases
- merged into the source, now the code is based on version 3.3.3r2
- for Unix part, and on 3.3.3r9 for Win32.
-
- - Unix vncviewer: When -tunnel option is specified in the command
- line, special rules are now used to choose preferred encoding. Now
- viewer does not think that server is running on the same machine
- when tunneling is on and the preferred encoding is now "tight"
- with default compression instead of raw.
-
- - Xvnc: Rules to set default pixel formats have been changed: now
- they are RGB565 instead of BGR556 for color depth 16, and RGB888
- instead of BGR888 for depth 24. This makes Xvnc compatible with
- Imlib renderer used in Gnome and also helps to avoid unnecessary
- pixel format translations in many cases.
-
- - Xvnc: X11 modifier mapped to META key is now Mod4 instead of Mod1.
- New -compatiblekbd option implemented in Xvnc to force META and
- ALT keys behave the same way as they do in the original AT&T's
- version.
-
- - A number of bugs fixed: viewer crashes after inflate() call, Xvnc
- CoRRE encoding problems, Xvnc bit-order issues in XCursor and
- RichCursor encodings, etc.
-
- - Java viewer now supports Tight encoding and cursor shape updates.
- Drawing techniques were changed, settings "Raw pixel drawing:
- Fast/Reliable" and "CopyRect: Fast/Reliable" removed from the
- Options panel since they do not make sense in new drawing model.
-
- - Other new features, optimizations, fixes and cleanups, see
- ChangeLog files.
-
-----------------------------------------------------------------------
-
-* VNC Tight Encoding 1.1
-
- - New ``gradient'' filter implemented in servers (it can be disabled
- in Xvnc with new -lazytight option). The filter preprocess
- full-color screen areas prior to compression in order to achieve
- better compression ratios (with the cost of slower compression).
- Vncviewers of version 1.0 had support for this filter already, but
- there was small bug causing image distortions in certain cases. So
- it is recommended to upgrade both servers and viewers.
-
- - Stupid bug fixed: extra unused color was included in palettes in
- many cases; compression ratios used to be worse than they should
- be.
-
- - The algorithm used to split large rectangles into parts has been
- changed. This change can increase compression ratios in many
- situations.
-
- - Byte-order issues in servers have been (hopefully) fixed.
-
- - Performance tuning, code rewrites and cleanups in various places.
-
-----------------------------------------------------------------------
-
-* VNC Tight Encoding 1.0
-
- - Initial release.
