GNU GENERAL PUBLIC LICENSE
|
||||
Version 2, June 1991
|
||||
|
||||
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
|
||||
59 Temple Place - Suite 330, Boston, MA 02111-1307, USA
|
||||
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.
|
||||
|
||||
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.)
|
||||
|
||||
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.
|
||||
|
||||
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.
|
||||
|
||||
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
|
||||
|
||||
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.

||||

|
||||
|
||||
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.

About TigerVNC
|
||||
==============
|
||||
|
||||
Virtual Network Computing (VNC) is a remote display system which allows you to
|
||||
view and interact with a virtual desktop environment that is running on another
|
||||
computer on the network. Using VNC, you can run graphical applications on a
|
||||
remote machine and send only the display from these applications to your local
|
||||
machine. VNC is platform-independent and supports a wide variety of operating
|
||||
systems and architectures as both servers and clients.
|
||||
|
||||
TigerVNC is a high-speed version of VNC based on the RealVNC 4 and X.org code
|
||||
bases. TigerVNC started as a next-generation development effort for TightVNC
|
||||
on Unix and Linux platforms, but it split from its parent project in early 2009
|
||||
so that TightVNC could focus on Windows platforms. TigerVNC supports a variant
|
||||
of Tight encoding that is greatly accelerated by the use of the libjpeg-turbo
|
||||
JPEG codec.

=============
|
||||
|
||||
All versions of TigerVNC contain the following programs:
|
||||
|
||||
* vncviewer - the cross-platform TigerVNC Viewer, written using FLTK.
|
||||
vncviewer connects to a VNC server and allows you to interact
|
||||
with the remote desktop being displayed by the VNC server. The
|
||||
VNC server can be running on a Windows or a Unix/Linux machine.
|
||||
|
||||
|
||||
Windows-Specific
|
||||
================
|
||||
|
||||
The Windows version of TigerVNC contains the following programs:
|
||||
|
||||
* winvnc - the TigerVNC Server for Windows. winvnc allows a Windows desktop to
|
||||
be accessed remotely using a VNC viewer.
|
||||
|
||||
winvnc may not work if the Fast User Switching or Remote Desktop features are
|
||||
in use.
|
||||
|
||||
|
||||
Unix/Linux-Specific (not Mac)
|
||||
=============================
|
||||
|
||||
The Unix/Linux version of TigerVNC contains the following programs:
|
||||
|
||||
* Xvnc - the TigerVNC Server for Unix. Xvnc is both a VNC server and an X
|
||||
server with a "virtual" framebuffer. You should normally use the
|
||||
vncserver script to start Xvnc.
|
||||
|
||||
* vncserver - a wrapper script which makes starting Xvnc more convenient.
|
||||
vncserver requires Perl.
|
||||
|
||||
* vncpasswd - a program which allows you to change the VNC password used to
|
||||
access your VNC server sessions (assuming that VNC authentication
|
||||
is being used.) The vncserver script will automatically launch
|
||||
this program if it detects that VNC authentication is in use and
|
||||
a VNC password has not yet been configured.
|
||||
|
||||
* vncconfig - a program which is used to configure and control a running
|
||||
instance of Xvnc.
|
||||
|
||||
* x0vncserver - an inefficient VNC server which continuously polls any X
|
||||
display, allowing it to be controlled via VNC. It is intended
|
||||
mainly as a demonstration of a simple VNC server.

.TH Xvnc 1 "" "TigerVNC" "Virtual Network Computing"
|
||||
.SH NAME
|
||||
Xvnc \- the X VNC server
|
||||
.SH SYNOPSIS
|
||||
.B Xvnc
|
||||
.RI [ options ]
|
||||
.RI : display#
|
||||
.SH DESCRIPTION
|
||||
.B Xvnc
|
||||
is the X VNC (Virtual Network Computing) server. It is based on a standard X
|
||||
server, but it has a "virtual" screen rather than a physical one. X
|
||||
applications display themselves on it as if it were a normal X display, but
|
||||
they can only be accessed via a VNC viewer - see \fBvncviewer\fP(1).
|
||||
|
||||
So Xvnc is really two servers in one. To the applications it is an X server,
|
||||
and to the remote VNC users it is a VNC server. By convention we have arranged
|
||||
that the VNC server display number will be the same as the X server display
|
||||
number, which means you can use eg. snoopy:2 to refer to display 2 on machine
|
||||
"snoopy" in both the X world and the VNC world.
|
||||
|
||||
The best way of starting \fBXvnc\fP is via the \fBvncserver\fP script. This
|
||||
sets up the environment appropriately and runs some X applications to get you
|
||||
going. See the manual page for \fBvncserver\fP(1) for more information.
|
||||
|
||||
.SH OPTIONS
|
||||
.B Xvnc
|
||||
takes lots of options - running \fBXvnc -help\fP gives a list. Many of these
|
||||
are standard X server options, which are described in the \fBXserver\fP(1)
|
||||
manual page. In addition to options which can only be set via the
|
||||
command-line, there are also "parameters" which can be set both via the
|
||||
command-line and through the \fBvncconfig\fP(1) program.
|
||||
|
||||
.TP
|
||||
.B \-geometry \fIwidth\fPx\fIheight\fP
|
||||
Specify the size of the desktop to be created. Default is 1024x768.
|
||||
.
|
||||
.TP
|
||||
.B \-depth \fIdepth\fP
|
||||
Specify the pixel depth in bits of the desktop to be created. Default is 24,
|
||||
other possible values are 8, 15, and 16 - anything else is likely to cause
|
||||
strange behaviour by applications.
|
||||
.
|
||||
.TP
|
||||
.B \-pixelformat \fIformat\fP
|
||||
Specify pixel format for server to use (BGRnnn or RGBnnn). The default for
|
||||
depth 8 is BGR233 (meaning the most significant two bits represent blue, the
|
||||
next three green, and the least significant three represent red), the default
|
||||
for depth 16 is RGB565 and for depth 24 is RGB888.
|
||||
.
|
||||
.TP
|
||||
.B \-interface \fIIP address\fP
|
||||
Listen on interface. By default Xvnc listens on all available interfaces.
|
||||
.
|
||||
.TP
|
||||
.B \-inetd
|
||||
This significantly changes Xvnc's behaviour so that it can be launched from
|
||||
inetd. See the section below on usage with inetd.
|
||||
.
|
||||
.TP
|
||||
.B \-help
|
||||
List all the options and parameters
|
||||
|
||||
.SH PARAMETERS
|
||||
VNC parameters can be set both via the command-line and through the
|
||||
\fBvncconfig\fP(1) program, and with a VNC-enabled Xorg server via Options
|
||||
entries in the xorg.conf file.
|
||||
|
||||
Parameters can be turned on with -\fIparam\fP or off with
|
||||
-\fIparam\fP=0. Parameters which take a value can be specified as
|
||||
-\fIparam\fP \fIvalue\fP. Other valid forms are \fIparam\fP\fB=\fP\fIvalue\fP
|
||||
-\fIparam\fP=\fIvalue\fP --\fIparam\fP=\fIvalue\fP. Parameter names are
|
||||
case-insensitive.
|
||||
|
||||
.TP
|
||||
.B \-desktop \fIdesktop-name\fP
|
||||
Each desktop has a name which may be displayed by the viewer. It defaults to
|
||||
"x11".
|
||||
.
|
||||
.TP
|
||||
.B \-rfbport \fIport\fP
|
||||
Specifies the TCP port on which Xvnc listens for connections from viewers (the
|
||||
protocol used in VNC is called RFB - "remote framebuffer"). The default is
|
||||
5900 plus the display number.
|
||||
.
|
||||
.TP
|
||||
.B \-UseIPv4
|
||||
Use IPv4 for incoming and outgoing connections. Default is on.
|
||||
.
|
||||
.TP
|
||||
.B \-UseIPv6
|
||||
Use IPv6 for incoming and outgoing connections. Default is on.
|
||||
.
|
||||
.TP
|
||||
.B \-rfbunixpath \fIpath\fP
|
||||
Specifies the path of a Unix domain socket on which Xvnc listens for
|
||||
connections from viewers, instead of listening on a TCP port.
|
||||
.
|
||||
.TP
|
||||
.B \-rfbunixmode \fImode\fP
|
||||
Specifies the mode of the Unix domain socket. The default is 0600.
|
||||
.
|
||||
.TP
|
||||
.B \-rfbwait \fItime\fP, \-ClientWaitTimeMillis \fItime\fP
|
||||
Time in milliseconds to wait for a viewer which is blocking the server. This is
|
||||
necessary because the server is single-threaded and sometimes blocks until the
|
||||
viewer has finished sending or receiving a message - note that this does not
|
||||
mean an update will be aborted after this time. Default is 20000 (20 seconds).
|
||||
.
|
||||
.TP
|
||||
.B \-httpd \fIdirectory\fP
|
||||
Run a mini-HTTP server which serves files from the given directory. Normally
|
||||
the directory will contain the classes for the Java viewer. In addition, files
|
||||
with a .vnc extension will have certain substitutions made so that a single
|
||||
installation of the Java VNC viewer can be served by separate instances of
|
||||
Xvnc.
|
||||
.
|
||||
.TP
|
||||
.B \-httpPort \fIport\fP
|
||||
Specifies the port on which the mini-HTTP server runs. Default is 5800 plus
|
||||
the display number.

|
||||
.TP
|
||||
.B \-rfbauth \fIpasswd-file\fP, \-PasswordFile \fIpasswd-file\fP
|
||||
Password file for VNC authentication. There is no default, you should
|
||||
specify the password file explicitly. Password file should be created with
|
||||
the \fBvncpasswd\fP(1) utility. The file is accessed each time a connection
|
||||
comes in, so it can be changed on the fly.
|
||||
.
|
||||
.TP
|
||||
.B \-AcceptCutText
|
||||

Accept requests to resize the size of the desktop. Default is on.
|
||||
.
|
||||
.TP
|
||||
.B \-DisconnectClients
|
||||
Disconnect existing clients if an incoming connection is non-shared. Default is
|
||||
on. If \fBDisconnectClients\fP is false, then a new non-shared connection will
|
||||
be refused while there is a client active. When combined with
|
||||
\fBNeverShared\fP this means only one client is allowed at a time.
|
||||
.
|
||||
.TP
|
||||
.B \-NeverShared
|
||||
Never treat incoming connections as shared, regardless of the client-specified

|
||||
.
|
||||
.TP
|
||||
.B \-FrameRate \fIfps\fP
|
||||
The maximum number of updates per second sent to each client. If the screen
|
||||
updates any faster then those changes will be aggregated and sent in a single
|
||||
update to the client. Note that this only controls the maximum rate and a
|
||||
client may get a lower rate when resources are limited. Default is \fB60\fP.
|
||||
.
|
||||
.TP
|
||||
.B \-CompareFB \fImode\fP
|
||||

.B \-Log \fIlogname\fP:\fIdest\fP:\fIlevel\fP
|
||||
Configures the debug log settings. \fIdest\fP can currently be \fBstderr\fP,
|
||||
\fBstdout\fP or \fBsyslog\fP, and \fIlevel\fP is between 0 and 100, 100 meaning
|
||||
most verbose output. \fIlogname\fP is usually \fB*\fP meaning all, but you can
|
||||
target a specific source file if you know the name of its "LogWriter". Default
|
||||
is \fB*:stderr:30\fP.

.B \-RemapKeys \fImapping
|

Sets up a keyboard mapping.
|

.I mapping
|
||||
is a comma-separated string of character mappings, each of the form
|
||||
.IR char -> char ,
|
||||
or
|
||||
.IR char <> char ,
|
||||
where
|
||||
.I char
|

.B \-AvoidShiftNumLock
|
||||
Key affected by NumLock often require a fake Shift to be inserted in order
|
||||
for the correct symbol to be generated. Turning on this option avoids these
|
||||
extra fake Shift events but may result in a slightly different symbol
|
||||
(e.g. a Return instead of a keypad Enter).
|

.
|
||||
.TP
|
||||
.B \-RawKeyboard
|
||||
Send keyboard events straight through and avoid mapping them to the current
|
||||
keyboard layout. This effectively makes the keyboard behave according to the
|
||||
layout configured on the server instead of the layout configured on the
|
||||
client. Default is off.
|
||||
.
|
||||
.TP
|
||||
.B \-AllowOverride
|
||||
Comma separated list of parameters that can be modified using VNC extension.
|
||||
Parameters can be modified for example using \fBvncconfig\fP(1) program from
|
||||
inside a running session.
|
||||
|
||||
Allowing override of parameters such as \fBPAMService\fP or \fBPasswordFile\fP
|
||||
can negatively impact security if Xvnc runs under different user than the
|
||||
programs allowed to override the parameters.
|
||||
|
||||
When \fBNoClipboard\fP parameter is set, allowing override of \fBSendCutText\fP
|
||||
and \fBAcceptCutText\fP has no effect.
|
||||
|
||||
Default is \fBdesktop,AcceptPointerEvents,SendCutText,AcceptCutText,SendPrimary,SetPrimary\fP.
|
||||
|
||||
.SH USAGE WITH INETD
|
||||
By configuring the \fBinetd\fP(1) service appropriately, Xvnc can be launched
|
||||
on demand when a connection comes in, rather than having to be started
|
||||
manually. When given the \fB-inetd\fP option, instead of listening for TCP
|
||||
connections on a given port it uses its standard input and standard output.
|
||||
There are two modes controlled by the wait/nowait entry in the inetd.conf file.
|
||||
|
||||
In the nowait mode, Xvnc uses its standard input and output directly as the
|
||||
connection to a viewer. It never has a listening socket, so cannot accept
|
||||
further connections from viewers (it can however connect out to listening
|
||||
viewers by use of the vncconfig program). Further viewer connections to the
|
||||
same TCP port result in inetd spawning off a new Xvnc to deal with each
|
||||
connection. When the connection to the viewer dies, the Xvnc and any
|
||||
associated X clients die. This behaviour is most useful when combined with the
|
||||
XDMCP options -query and -once. An typical example in inetd.conf might be (all
|
||||
on one line):
|
||||
|
||||
5950 stream tcp nowait nobody /usr/local/bin/Xvnc Xvnc -inetd -query
|
||||
localhost -once securitytypes=none
|
||||
|
||||
In this example a viewer connection to :50 will result in a new Xvnc for that
|
||||
connection which should display the standard XDM login screen on that machine.
|
||||
Because the user needs to login via XDM, it is usually OK to accept connections
|
||||
without a VNC password in this case.
|
||||
|
||||
In the wait mode, when the first connection comes in, inetd gives the listening
|
||||
socket to Xvnc. This means that for a given TCP port, there is only ever one
|
||||
Xvnc at a time. Further viewer connections to the same port are accepted by
|
||||
the same Xvnc in the normal way. Even when the original connection is broken,
|
||||
the Xvnc will continue to run. If this is used with the XDMCP options -query
|
||||
and -once, the Xvnc and associated X clients will die when the user logs out of
|
||||
the X session in the normal way. It is important to use a VNC password in this
|
||||
case. A typical entry in inetd.conf might be:
|
||||
|
||||
5951 stream tcp wait james /usr/local/bin/Xvnc Xvnc -inetd -query localhost -once passwordFile=/home/james/.vnc/passwd
|
||||
|
||||
In fact typically, you would have one entry for each user who uses VNC
|
||||
regularly, each of whom has their own dedicated TCP port which they use. In
|
||||
this example, when user "james" connects to :51, he enters his VNC password,
|
||||
then gets the XDM login screen where he logs in in the normal way. However,
|
||||
unlike the previous example, if he disconnects, the session remains persistent,
|
||||
and when he reconnects he will get the same session back again. When he logs
|
||||
out of the X session, the Xvnc will die, but of course a new one will be
|
||||
created automatically the next time he connects.

.SH DESCRIPTION
|
||||
.B vncconfig
|
||||
is used to configure and control a running instance of Xvnc, or any other X
|
||||
server with the VNC extension. Note that it cannot be used to control VNC
|
||||
servers prior to version 4.
|
||||
|
||||
When run with no options, it runs as a kind of "helper" application for Xvnc.
|
||||
Its main purpose when run in this mode is to query the user how new
|
||||
connections should be handled (provided this feature is enabled). The
|
||||
\fB-nowin\fP flag can be used if you always want the query support but don't
|
||||
wish to clutter the desktop with the settings window - alternatively the
|
||||
\fB-iconic\fP option can be used to make it iconified by default.
|
||||
|
||||
When run in any other mode, \fBvncconfig\fP is a one-shot program used to
|
||||
configure or control Xvnc as appropriate. It can be used to tell Xvnc to
|
||||
connect or disconnect from listening viewers, and to set and retrieve Xvnc's
|
||||
parameters.
|
||||
|
||||
Note that the DISPLAY environment variable or the \fB\-display\fP option
|
||||
must be set as appropriate to control Xvnc. If you run it on an ordinary X
|
||||
server (or on a version 3 Xvnc) you will get an error message saying that there
|
||||
is no VNC extension.
|
||||
|
||||
.SH OPTIONS
|
||||
.TP
|
||||
.B \-connect \fIhost\fP[:\fIport\fP]
|
||||
Tells an Xvnc server to make a "reverse" connection to a listening VNC viewer
|
||||
(normally connections are made the other way round - the viewer connects to the
|
||||
server). \fIhost\fP is the host where the listening viewer is running. If it's
|
||||
not listening on the default port of 5500, you can specify \fIhost:port\fP
|
||||
instead.
|
||||
.
|
||||
.TP
|
||||
.B \-disconnect
|
||||
This causes Xvnc to disconnect from all viewers so that the VNC desktop is not
|
||||
displayed anywhere.
|
||||
.
|
||||
.TP
|
||||
[\fB-set\fP] \fIXvnc-param\fP=\fIvalue\fP
|
||||
Sets an Xvnc parameter to the given value. Note that some of Xvnc's parameters
|
||||
are read only once at startup so that changing them in this way may not have
|
||||
any effect.
|
||||

|
||||
.B \-desc \fIXvnc-param\fP
|
||||
Prints a short description of the given Xvnc parameter.
|
||||
|
||||
.SH PARAMETERS
|
||||
.B vncconfig
|
||||
also has parameters of its own which can be set on the command line. These
|
||||
should not be confused with Xvnc's parameters which are manipulated with the
|
||||
\fB-set\fP, \fB-get\fP, \fB-list\fP and \fB-desc\fP options.
|
||||
|
||||
Parameters can be turned on with -\fIparam\fP or off with -\fIparam\fP=0.
|
||||
Parameters which take a value can be specified as -\fIparam\fP \fIvalue\fP.
|
||||
Other valid forms are \fIparam\fP\fB=\fP\fIvalue\fP -\fIparam\fP=\fIvalue\fP
|
||||
--\fIparam\fP=\fIvalue\fP. Parameter names are case-insensitive.

|
||||
.SH DESCRIPTION
|
||||
.B vncpasswd
|
||||
allows you to set the password used to access VNC desktops. Its default
|
||||
behavior is to prompt for a VNC password and then store an obfuscated version
|
||||
of this password to \fIpasswd-file\fR (or to $HOME/.vnc/passwd if no password
|
||||
file is specified.) The \fBvncserver\fP script runs \fBvncpasswd\fP the first
|
||||
time you start a VNC desktop, and it invokes \fBXvnc\fP with the appropriate
|
||||
\fB\-rfbauth\fP option. \fBvncviewer\fP can also be given a password file to
|
||||
use via the \fB\-passwd\fP option.
|
||||
|
||||
The password must be at least six characters long (unless the \fB\-f\fR
|
||||
command-line option is used-- see below), and only the first eight
|
||||
characters are significant. Note that the stored password is \fBnot\fP
|
||||
encrypted securely - anyone who has access to this file can trivially find out
|
||||
the plain-text password, so \fBvncpasswd\fP always sets appropriate permissions
|
||||
(read and write only by the owner.) However, when accessing a VNC desktop, a
|
||||
challenge-response mechanism is used over the wire making it hard for anyone to
|
||||
crack the password simply by snooping on the network.

.SH DESCRIPTION
|
||||
.B vncserver
|
||||
is used to start a VNC (Virtual Network Computing) desktop.
|
||||
.B vncserver
|
||||
is a Perl script which simplifies the process of starting an Xvnc server. It
|
||||
runs Xvnc with appropriate options and starts a window manager on the VNC
|
||||
desktop.
|
||||
|
||||
.B vncserver
|
||||
can be run with no options at all. In this case it will choose the first
|
||||
available display number (usually :1), start Xvnc with that display number,
|
||||
and start the default window manager in the Xvnc session. You can also
|
||||
specify the display number, in which case vncserver will attempt to start
|
||||
Xvnc with that display number and exit if the display number is not
|
||||
available. For example:
|
||||
|
||||
.RS
|
||||
vncserver :13
|
||||
.RE
|
||||
|
||||
Editing the file $HOME/.vnc/xstartup allows you to change the applications run
|
||||
at startup (but note that this will not affect an existing VNC session.)
|
||||
|
||||
.SH OPTIONS
|
||||
You can get a list of options by passing \fB\-h\fP as an option to vncserver.
|
||||
In addition to the options listed below, any unrecognised options will be
|
||||
passed to Xvnc - see the Xvnc man page, or "Xvnc \-help", for details.
|
||||
|
||||
.TP
|
||||
.B \-name \fIdesktop-name\fP
|
||||
Each VNC desktop has a name which may be displayed by the viewer. The desktop
|
||||
name defaults to "\fIhost\fP:\fIdisplay#\fP (\fIusername\fP)", but you can
|
||||
change it with this option. The desktop name option is passed to the xstartup
|
||||
script via the $VNCDESKTOP environment variable, which allows you to run a
|
||||
different set of applications depending on the name of the desktop.
|
||||
.
|
||||
.TP
|
||||
.B \-geometry \fIwidth\fPx\fIheight\fP
|
||||
Specify the size of the VNC desktop to be created. Default is 1024x768.
|
||||
.
|
||||
.TP
|
||||
.B \-depth \fIdepth\fP
|
||||
Specify the pixel depth (in bits) of the VNC desktop to be created. Default is
|
||||
24. Other possible values are 8, 15 and 16 - anything else is likely to cause
|
||||
strange behaviour by applications.
|
||||
.
|
||||
.TP
|
||||
.B \-pixelformat \fIformat\fP
|
||||
Specify pixel format for Xvnc to use (BGRnnn or RGBnnn). The default for
|
||||
depth 8 is BGR233 (meaning the most significant two bits represent blue, the
|
||||
next three green, and the least significant three represent red), the default
|
||||
for depth 16 is RGB565, and the default for depth 24 is RGB888.
|
||||
.
|
||||
.TP
|
||||
.B \-cc 3
|
||||
As an alternative to the default TrueColor visual, this allows you to run an
|
||||
Xvnc server with a PseudoColor visual (i.e. one which uses a color map or
|
||||
palette), which can be useful for running some old X applications which only
|
||||
work on such a display. Values other than 3 (PseudoColor) and 4 (TrueColor)
|
||||
for the \-cc option may result in strange behaviour, and PseudoColor desktops
|
||||
must have an 8-bit depth.
|
||||
.
|
||||
.TP
|
||||
.B \-kill :\fIdisplay#\fP
|
||||
This kills a VNC desktop previously started with vncserver. It does this by
|
||||
killing the Xvnc process, whose process ID is stored in the file
|
||||
"$HOME/.vnc/\fIhost\fP:\fIdisplay#\fP.pid". The
|
||||
.B \-kill
|
||||
option ignores anything preceding the first colon (":") in the display
|
||||
argument. Thus, you can invoke "vncserver \-kill $DISPLAY", for example at the
|
||||
end of your xstartup file after a particular application exits.
|
||||
.
|
||||
.TP
|
||||
.B \-fp \fIfont-path\fP
|
||||
If the vncserver script detects that the X Font Server (XFS) is running, it
|
||||
will attempt to start Xvnc and configure Xvnc to use XFS for font handling.
|
||||
Otherwise, if XFS is not running, the vncserver script will attempt to start
|
||||
Xvnc and allow Xvnc to use its own preferred method of font handling (which may
|
||||
be a hard-coded font path or, on more recent systems, a font catalog.) In
|
||||
any case, if Xvnc fails to start, the vncserver script will then attempt to
|
||||
determine an appropriate X font path for this system and start Xvnc using
|
||||
that font path.
|
||||
|
||||
The
|
||||
.B \-fp
|
||||
argument allows you to override the above fallback logic and specify a font
|
||||
path for Xvnc to use.
|
||||
.
|
||||
.TP
|
||||
.B \-fg
|
||||
Runs Xvnc as a foreground process. This has two effects: (1) The VNC server
|
||||
can be aborted with CTRL-C, and (2) the VNC server will exit as soon as the
|
||||
user logs out of the window manager in the VNC session. This may be necessary
|
||||
when launching TigerVNC from within certain grid computing environments.
|
||||
.
|
||||
.TP
|
||||
.B \-autokill
|
||||
Automatically kill Xvnc whenever the xstartup script exits. In most cases,
|
||||
this has the effect of terminating Xvnc when the user logs out of the window
|
||||
manager.
|
||||
.
|
||||
.TP
|
||||
.B \-noxstartup
|
||||
Do not run the %HOME/.vnc/xstartup script after launching Xvnc. This
|
||||
option allows you to manually start a window manager in your TigerVNC session.
|
||||
.
|
||||
.TP
|
||||
.B \-xstartup \fIscript\fP
|
||||
Run a custom startup script, instead of %HOME/.vnc/xstartup, after launching
|
||||
Xvnc. This is useful to run full-screen applications.
|
||||
.
|

.TP
|

.B \-list
|

Lists all VNC desktops started by vncserver.
|

.SH FILES
|
||||
Several VNC-related files are found in the directory $HOME/.vnc:
|
||||
.TP
|
||||
$HOME/.vnc/xstartup
|
||||
A shell script specifying X applications to be run when a VNC desktop is
|
||||
started. If this file does not exist, then vncserver will create a default
|
||||
xstartup script which attempts to launch your chosen window manager.
|
||||
.TP
|
||||
/etc/tigervnc/vncserver-config-defaults
|
||||
The optional system-wide equivalent of $HOME/.vnc/config. If this file exists
|
||||
and defines options to be passed to Xvnc, they will be used as defaults for
|
||||
users. The user's $HOME/.vnc/config overrides settings configured in this file.
|
||||
The overall configuration file load order is: this file, $HOME/.vnc/config,
|
||||
and then /etc/tigervnc/vncserver-config-mandatory. None are required to exist.
|
||||
.TP
|
||||
/etc/tigervnc/vncserver-config-mandatory
|
||||
The optional system-wide equivalent of $HOME/.vnc/config. If this file exists
|
||||
and defines options to be passed to Xvnc, they will override any of the same
|
||||
options defined in a user's $HOME/.vnc/config. This file offers a mechanism
|
||||
to establish some basic form of system-wide policy. WARNING! There is
|
||||
nothing stopping users from constructing their own vncserver-like script
|
||||
that calls Xvnc directly to bypass any options defined in
|
||||
/etc/tigervnc/vncserver-config-mandatory. Likewise, any CLI arguments passed
|
||||
to vncserver will override ANY config file setting of the same name. The
|
||||
overall configuration file load order is:
|
||||
/etc/tigervnc/vncserver-config-defaults, $HOME/.vnc/config, and then this file.
|
||||
None are required to exist.
|
||||
.TP
|
||||
$HOME/.vnc/config
|
||||
An optional server config file wherein options to be passed to Xvnc are listed
|
||||
to avoid hard-coding them to the physical invocation. List options in this file
|
||||
one per line. For those requiring an argument, simply separate the option from
|
||||
the argument with an equal sign, for example: "geometry=2000x1200" or
|
||||
"securitytypes=vncauth,tlsvnc". Options without an argument are simply listed
|
||||
as a single word, for example: "localhost" or "alwaysshared".
|
||||
.TP
|
||||
$HOME/.vnc/passwd
|
||||
The VNC password file.
|
||||
.TP
|
||||
$HOME/.vnc/\fIhost\fP:\fIdisplay#\fP.log
|
||||
The log file for Xvnc and applications started in xstartup.
|
||||
.TP
|
||||
$HOME/.vnc/\fIhost\fP:\fIdisplay#\fP.pid
|
||||
Identifies the Xvnc process ID, used by the
|
||||
.B \-kill
|
||||
option.

.SH DESCRIPTION
|
||||
.B vncviewer
|
||||
is a viewer (client) for Virtual Network Computing. This manual page documents
|
||||
version 4 for the X window system.
|
||||
|
||||
If you run the viewer with no arguments it will prompt you for a VNC server to
|
||||
connect to. Alternatively, specify the VNC server as an argument, e.g.:
|
||||
|
||||
.RS
|
||||
vncviewer snoopy:2
|
||||
.RE
|
||||
|
||||
where 'snoopy' is the name of the machine, and '2' is the display number of the
|
||||
VNC server on that machine. Either the machine name or display number can be
|
||||
omitted. So for example ":1" means display number 1 on the same machine, and
|
||||
"snoopy" means "snoopy:0" i.e. display 0 on machine "snoopy".
|
||||
|
||||
As another quick way to start a connection to a VNC server, specify a .tigervnc
|
||||
configuration file as an argument to the viewer, e.g.:
|
||||
|
||||
.RS
|
||||
vncviewer ./some.tigervnc
|
||||
.RE
|
||||
|
||||
where './some.tigervnc' is an existing and valid TigerVNC configuration file.
|
||||
The file name needs to include a path separator. Additional options may be
|
||||
given too, but the given configuration file will overwrite any conflicting
|
||||
parameters.
|
||||
|
||||
If the VNC server is successfully contacted, you will be prompted for a
|
||||
password to authenticate you. If the password is correct, a window will appear
|
||||
showing the desktop of the VNC server.
|
||||
|
||||
.SH AUTOMATIC PROTOCOL SELECTION
|
||||
|
||||
The viewer tests the speed of the connection to the server and chooses the
|
||||
encoding and pixel format (color level) appropriately. This makes it much
|
||||
easier to use than previous versions where the user had to specify arcane
|
||||
command line arguments.
|
||||
|
||||
The viewer normally starts out assuming the link is slow, using the
|
||||
encoding with the best compression. If it turns out that the link is
|
||||
fast enough it switches to an encoding which compresses less but is
|
||||
faster to generate, thus improving the interactive feel.
|
||||
|
||||
The viewer normally starts in full-color mode, but switches to
|
||||
low-color mode if the bandwidth is insufficient. However, this only
|
||||
occurs when communicating with servers supporting protocol 3.8 or
|
||||
newer, since many old servers does not support color mode changes
|
||||
safely.
|
||||
|
||||
Automatic selection can be turned off by setting the
|
||||
\fBAutoSelect\fP parameter to false, or from the options dialog.
|
||||
|
||||
.SH POPUP MENU
|
||||
The viewer has a popup menu containing entries which perform various actions.
|
||||
It is usually brought up by pressing F8, but this can be configured with the
|
||||
MenuKey parameter. Actions which the popup menu can perform include:
|
||||
.RS 2
|
||||
.IP * 2
|
||||
switching in and out of full-screen mode
|
||||
.IP *
|
||||
quitting the viewer
|
||||
.IP *
|
||||
generating key events, e.g. sending ctrl-alt-del
|
||||
.IP *
|
||||
accessing the options dialog and various other dialogs
|
||||
.RE
|
||||
.PP
|
||||
By default, key presses in the popup menu get sent to the VNC server and
|
||||
dismiss the popup. So to get an F8 through to the VNC server simply press it
|
||||
twice.
|
||||
|
||||
.SH FULL SCREEN MODE
|
||||
A full-screen mode is supported. This is particularly useful when connecting
|
||||
to a remote screen which is the same size as your local one. If the remote
|
||||
screen is bigger, you can scroll by bumping the mouse against the edge of the
|
||||
screen.
|
||||
|
||||
.SH OPTIONS (PARAMETERS)
|
||||
You can get a list of parameters by giving \fB\-h\fP as a command-line option
|
||||
to vncviewer. Parameters can be turned on with -\fIparam\fP or off with
|
||||
-\fIparam\fP=0. Parameters which take a value can be specified as
|
||||
-\fIparam\fP \fIvalue\fP. Other valid forms are \fIparam\fP\fB=\fP\fIvalue\fP
|
||||
-\fIparam\fP=\fIvalue\fP --\fIparam\fP=\fIvalue\fP. Parameter names are
|
||||
case-insensitive.
|
||||
|
||||
Many of the parameters can also be set graphically via the options dialog box.
|
||||
This can be accessed from the popup menu or from the "Connection details"
|
||||
dialog box.
|
||||
|
||||
.TP
|
||||
.B \-display \fIXdisplay\fP
|
||||

|
||||
.B \-listen \fI[port]\fP
|
||||
Causes vncviewer to listen on the given port (default 5500) for reverse
|
||||
connections from a VNC server. WinVNC supports reverse connections initiated
|
||||
using the 'Add New Client' menu option or the '\-connect' command-line option.
|
||||
Xvnc supports reverse connections with a helper program called
|
||||
.B vncconfig.
|
||||
.
|
||||
.TP
|
||||
.B \-SecurityTypes \fIsec-types\fP
|
||||

\fBVncAuth\fP, \fBPlain\fP, \fBTLSNone\fP, \fBTLSVnc\fP, \fBTLSPlain\fP,
|
||||
\fBX509None\fP, \fBX509Vnc\fP and \fBX509Plain\fP. Default is to attempt
|
||||
every supported scheme.
|
||||
.
|
||||
.TP
|
||||
.B \-passwd, \-PasswordFile \fIpassword-file\fP
|
||||
If you are on a filesystem which gives you access to the password file used by
|
||||
the server, you can specify it here to avoid typing it in. It will usually be
|
||||
"~/.vnc/passwd".
|
||||
.
|
||||
.TP
|
||||
.B \-X509CA \fIpath\fP
|
||||

|
||||
.
|
||||
.TP
|
||||
.B \-Shared
|
||||
When you make a connection to a VNC server, all other existing connections are
|
||||
normally closed. This option requests that they be left open, allowing you to
|
||||
share the desktop with someone already using it.
|
||||
.
|
||||
.TP
|
||||
.B \-ViewOnly
|
||||
Specifies that no keyboard or mouse events should be sent to the server.
|
||||
Useful if you want to view a desktop without interfering; often needs to be
|
||||
combined with
|
||||
.B \-Shared.
|
||||

.B \-DesktopSize \fIwidth\fPx\fIheight\fP
|
||||
Instead of keeping the existing remote screen size, the client will attempt to
|
||||
switch to the specified since when connecting. If the server does not support
|
||||
the SetDesktopSize message then the screen will retain the original size.
|
||||
.
|
||||
.TP
|
||||
.B \-RemoteResize
|
||||
Dynamically resize the remote desktop size as the size of the local client

|
||||
vncviewer. If you would like to force vncviewer to use reduced color level
|
||||
use \fB-AutoSelect=0\fP parameter.
|
||||
.
|
||||
.TP
|
||||
.B \-PreferredEncoding \fIencoding\fP
|
||||
This option specifies the preferred encoding to use from one of "Tight", "ZRLE",

/usr/bin/ssh. Note that when using the \fB\-via\fR option, the host
|
||||
machine name should be specified as known to the gateway machine, e.g.
|
||||
"localhost" denotes the \fIgateway\fR, not the machine where vncviewer
|
||||
was launched. The environment variable \fIVNC_VIA_CMD\fR can override
|
||||
the default tunnel command of
|
||||
\fB/usr/bin/ssh\ -f\ -L\ "$L":"$H":"$R"\ "$G"\ sleep\ 20\fR. The tunnel
|
||||
command is executed with the environment variables \fIL\fR, \fIH\fR,
|

.SH DESCRIPTION
|
||||
.B x0vncserver
|
||||
is a TigerVNC Server which makes any X display remotely accessible via VNC,
|
||||
TigerVNC or compatible viewers. Unlike \fBXvnc\fP(1), it does not create a
|
||||
virtual display. Instead, it just shares an existing X server (typically,
|
||||
that one connected to the physical screen).
|
||||
|
||||
XDamage will be used if the existing X server supports it. Otherwise
|
||||
.B x0vncserver
|
||||
will fall back to polling the screen for changes.
|
||||
|
||||
.SH OPTIONS
|
||||
.B x0vncserver
|
||||
interprets the command line as a list of parameters with optional values.
|
||||
Running \fBx0vncserver -h\fP will show a list of all valid parameters with
|
||||
short descriptions. All parameters are optional, but normally you would have
|
||||
to use the \fBPasswordFile\fP parameter (see its description below).
|
||||
.PP
|
||||
There are several forms of specifying parameters in the command line (here we
|
||||
use `\fISomeParameter\fP' as an example parameter name):
|
||||
|
||||
.TP
|
||||
.B -\fISomeParameter\fP
|
||||
Enable the parameter, turn the feature on. This form can be used with
|
||||
parameters that simply enable or disable some feature.
|
||||
.
|
||||
.TP
|
||||
.B -\fISomeParameter\fP=0
|
||||
Disable the parameter, turn the feature off.
|
||||
.
|
||||
.TP
|
||||
.B -\fISomeParameter\fP=\fIvalue\fP
|
||||
Assign the specified \fIvalue\fP to the parameter. The leading dash can be

|
||||
|
||||
|
||||
Installation
|
||||
============
|
||||
|
||||
There are three basic ways to use the TigerVNC Java Viewer:
|
||||
|
||||
1. Running the applet as part of a TigerVNC Server installation.
|
||||
|
||||
Both the Unix and Windows versions of the TigerVNC Server include a small
|
||||
built-in HTTP server that can serve the TigerVNC Java Viewer to web
|
||||
clients. This enables easy access to the shared desktop without the need
|
||||
to install any software on the client machine.
|
||||
|
||||
The Unix TigerVNC Server (Xvnc) is able to serve up any set of files that
|
||||
are present in a particular directory, which is specified in the -httpd
|
||||
argument to Xvnc. The default version of the vncserver script will look
|
||||
for a directory called vnc/classes, one level up from the directory
|
||||
containing the vncserver script, then it will look for a directory called
|
||||
/usr/share/vnc/classes, then /usr/local/vnc/classes. It will set the
|
||||
-httpd argument to Xvnc to the first one of these VNC classes directories
|
||||
it finds. Thus, one can easily deploy a modified version of the TigerVNC
|
||||
Java Viewer by simply copying a new version of VncViewer.jar and/or
|
||||
index.vnc into the VNC classes directory.
|
||||
|
||||
On Windows and Linux, the embedded applet can be drag-undocked from the
|
||||
browser window and converted to a standalone application. The drag
|
||||
gesture ALT+drag on Windows, and SHIFT+drag on Linux.
|
||||
|
||||
In the case of the Windows TigerVNC Server, VncViewer.jar and index.vnc
|
||||
are embedded as resources in the WinVNC executable, so deploying a
|
||||
modified version of the TigerVNC Java Viewer on a Windows server requires
|
||||
rebuilding WinVNC.
|
||||
|
||||
2. Running the applet from a standalone web server.
|
||||
|
||||
Another possibility for using the TigerVNC Java Viewer is to install it
|
||||
under a fully-functional HTTP server, such as Apache or IIS. Due to Java
|
||||
security restrictions, the applet must be signed in order for it to
|
||||
connect to a VNC server running on a different machine from the HTTP
|
||||
server.
|
||||
|
||||
One can install the TigerVNC Java Viewer by simply copying the .class and
|
||||
.jar files into a directory that is under the control of the HTTP server.
|
||||
Also, an HTML page should be created to act as a the base document for the
|
||||
TigerVNC Java Viewer applet (an example named index.html is provided in
|
||||
this directory. Modify this file to suit your specific needs.)
|
||||
|
||||
3. Running the viewer as a standalone application.
|
||||
|
||||
Finally, the TigerVNC Java Viewer can be executed locally on the client
|
||||
machine, but this method requires installation of either a JRE (Java
|
||||
Runtime Environment) or a JDK (Java Development Kit). If VncViewer.jar is
|
||||
in the current directory, then the TigerVNC Java Viewer can be launched
|
||||
with the following command line:
|
||||
|
||||
java -jar VncViewer.jar [parameters]
|
||||
|
||||
Add an argument of -? to the above command line to print a list of
|
||||
optional parameters supported by VncViewer.
|
||||
|
||||
|
||||
Parameters
|
||||
==========
|
||||
|
||||
The TigerVNC Java Viewer accepts a number of optional parameters, allowing you
|
||||
to customize its behavior.
|
||||
|
||||
Parameters can be specified in one of the two ways, depending on how the
|
||||
TigerVNC Java Viewer is used:
|
||||
|
||||
1. When the TigerVNC Java Viewer is run as an applet (embedded within an HTML
|
||||
document), parameters should be specified using the <PARAM> HTML tags
|
||||
within the appropriate <APPLET> section. Example:
|
||||
|
||||
<APPLET CODE=com.tigervnc.vncviewer.VncViewer ARCHIVE=VncViewer.jar
|
||||
WIDTH=400 HEIGHT=300>
|
||||
<PARAM NAME="PORT" VALUE=5901>
|
||||
<PARAM NAME="ScalingFactor" VALUE=50>
|
||||
</APPLET>
|
||||
|
||||
2. When run as a standalone application, the TigerVNC Java Viewer reads
|
||||
parameters from the command line. Example:
|
||||
|
||||
java -jar VncViewer.jar Port=5901 ScalingFactor=50
|
||||
|
||||
Both parameter names and their values are case-insensitive.
|
||||
|
||||
For a complete list of parameters and their descriptions, run:
|
||||
|
||||
java -jar VncViewer.jar -?
