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.

Enhanced TightVNC Viewer package
Copyright (c) Karl J. Runge <runge@karlrunge.com>
All rights reserved.
These packages provide 1) An enhanced TightVNC Viewer on Unix, 2) Binaries
for many Operating Systems (including Windows) for your convenience,
3) Wrapper scripts and etc. for gluing them all together.
One can straight-forwardly download all of the components and get them
to work together by oneself: this package is mostly for your convenience
to combine and wrap together the freely available software.
Bundled software co-shipped in this package is copyright and licensed
by others. See these sites and related ones for more information:
http://www.tightvnc.com
http://www.realvnc.com
http://www.stunnel.org
http://www.openssl.org
http://www.chiark.greenend.org.uk/~sgtatham/putty/
Note: Some of the Windows binaries included contain cryptographic software
that you may not be allowed to download, use, or redistribute. Please
check your situation first before downloading any of these packages.
See the survey http://rechten.uvt.nl/koops/cryptolaw/index.htm for useful
information. The Unix programs do not contain cryptographic software, but
rather will make use of cryptographic libraries that are installed on your
Unix system. Depending on your circumstances you may still need to check.
All work by Karl J. Runge in this package is Copyright (c) Karl J. Runge
and is licensed under the GPL as described in the file COPYING in this
directory.
All the files and information in this package are provided "AS IS"
without any warranty of any kind. Use them at your own risk.
=============================================================================
This package contains a convenient collection of enhanced TightVNC viewers
and stunnel binaries for different flavors of Unix and wrapper scripts,
etc to glue them together. SSL and SSH encryption tunnelling is provided.
Also, a Windows SSL wrapper for the co-bundled TightVNC binary and other
utilities are provided. (Launch ssl_tightvncviewer.exe in the
Windows subdirectory).
Features:
--------
The enhanced TightVNC viewer features are:
- SSL support for connections using the co-bundled stunnel program.
- Automatic SSH connections from the GUI (ssh must already be
installed on Unix; co-bundled plink is used on Windows)
- rfbNewFBSize VNC support on Unix (screen resizing)
- cursor alphablending with x11vnc at 32bpp (-alpha option, Unix only)
- xgrabserver support for fullscreen mode, for old window
managers (-grab option, Unix only).
- Automatic Service tunnelling via SSH for CUPS and SMB Printing,
ESD/ARTSD Audio, and SMB (Windows/Samba) filesystem mounting.
- Port Knocking for "closed port" SSH/SSL connections. In addition
to a simple fixed port sequence and one-time-pad implementation,
a hook is also provided to run any port knocking client before a
connecting.
Your package should have included binaries for many OS's: Linux, Solaris,
FreeBSD, etc. See the subdirectories of
./bin
for the ones that were shipped in this package, e.g. ./bin/Linux.i686
Run "uname -sm" to see your OS+arch combination. (See the
./bin/tightvncviewer -h output for how to override platform autodection
via the UNAME env. var).
If you need to Build:
--------------------
If your OS/arch is not included, the script "build.unix" may be able to
successfully build on for you and deposit the binaries down in ./bin/...
using the included source code.
You must run the build.unix script from this directory (that this toplevel
README is in) and like this:
./build.unix
The programs:
------------
The wrapper scripts:
./bin/ssl_tightvncviewer
./bin/tightvncviewer
are the main programs you will run and will try to autodetect your OS+arch
combination and if binaries are present for it automatically use them.
(if not found try the running the build.unix script).
If you prefer a GUI to prompt for parameters and then start ssl_tightvncviewer
you can run this instead:
./bin/ssl_vnc_gui
this is essentially the same GUI that is run on Windows (the
ssl_tightvncviewer.exe).
Using the GUI is it impossible to initiate a VNC connection that is not
encrypted with either SSL or SSH. Unencrypted VNC connections can only
be started by manually running the ./bin/tightvncviewer script.
For convenience, you can make symlinks from a directory in your PATH to
any of the 3 programs above you wish to run. That is all you usually
need to do for it to pick up all of the binaries, utils, etc. E.g.
assuming $HOME/bin is in your $PATH:
cd $HOME/bin
ln -s /path/to/enhanced_tightvnc_viewer/bin/{s,t}* .
(note the "." at the end). The above commands is basically the way to
"install" this package on Unix.
On Windows run:
Windows/ssl_tightvncviewer.exe
Examples:
--------
Use enhanced TightVNC unix viewer to connect to x11vnc via SSL:
./bin/ssl_tightvncviewer far-away.east:0
./bin/tightvncviewer -ssl far-away.east:0 (same)
./bin/ssl_vnc_gui (start GUI launcher)
Use enhanced TightVNC unix viewer without SSL:
./bin/tightvncviewer far-away.east:0
Use SSL to connect to a x11vnc server, and also verify the server's
identity using the SSL Certificate in the file ./x11vnc.pem:
./bin/ssl_tightvncviewer -alpha -verify ./x11vnc.pem far-away.east:0
(also turns on the viewer-side cursor alphablending hack).
Brief description of the subdirectories:
---------------------------------------
./bin/util some utility scripts, e.g. ssl_vncviewer
and ssl_tightvncviewer.tcl
./src source code and patches.
./src/zips zip files of source code and binaries.
./src/vnc_unixsrc unpacked tightvnc source code tree.
./src/stunnel-4.14 unpacked stunnel source code tree.
./src/patches patches to TightVNC viewer for the new
features on Unix (used by build.unix).
./src/tmp temporary build dir for build.unix
(the last four are used by build.unix)
./man man pages for TightVNC viewer and stunnel.
./Windows Stock TightVNC viewer and Stunnel, Openssl
etc Windows binaries. ssl_tightvncviewer.exe
is the program to run.
Since they are large, depending on which package you use not all of the
above may be present in your package.
Help and Info:
-------------
For more help on other options and usage patterns run these:
./bin/ssl_tightvncviewer -h
./bin/tightvncviewer -h
./bin/util/ssl_vncviewer -h

Windows:
-------
A wrapper to create a STUNNEL tunnel and then launch the
Windows TightVNC viewer is provided in:
Windows/ssl_tightvncviewer.exe
Just launch it and fill in the remote VNC display.
Click the Help buttons for more info. There is also a
Windows/README.txt file.
On Windows you may need to terminate the STUNNEL process
from the System Tray if the tool cannot terminate it
by itself. Just right-click on the STUNNEL icon.

This is a Windows utility to automatically start up STUNNEL to redirect
SSL VNC connections to a remote host. Then TightVNC Viewer (included)
is launched to used this SSL tunnel.
An example server would be "x11vnc -ssl", or any VNC server with a
2nd STUNNEL program running on the server side.
Just click on the program "ssl_tightvncviewer.exe", and then enter
the remote VNC Server and click "Connect". Click on "Help" for more
information. You can also set some simple options under "Options ..."
Note that on Windows when the TightVNC viewer disconnects you may need to
terminate the STUNNEL program manually. To do this: Click on the STUNNEL
icon (dark green) on the System Tray and then click "Exit". Before that,
however, you will be prompted if you want ssl_tightvncviewer.exe to try
to terminate STUNNEL for you. (Note that even if STUNNEL termination is
successful, the Tray Icon may not go away until the mouse hovers over it!)
With this STUNNEL and TightVNC Viewer wrapper you can also enable using
SSL Certificates with STUNNEL, and so the connection is not only encrypted
but it is also not susceptible to man-in-the-middle attacks.
See the STUNNEL and x11vnc documentation for how to create and add SSL
Certificates (PEM files) for authentication. Click on the "Certs ..."
button to specify the certificate(s). See the Help there for more info
and also:
http://www.karlrunge.com/x11vnc
http://www.tightvnc.com
http://www.stunnel.org
http://www.openssl.org
http://www.chiark.greenend.org.uk/~sgtatham/putty/
You can use x11vnc to create certificates if you like:

Misc:
The openssl.exe stunnel.exe vncviewer.exe libeay32.dll
libssl32.dll programs came from the websites mentioned above.
IMPORTANT: some of these binaries may have cryptographic
software that you may not be allowed to download or use.
See the above websites for more information and also the
util/info subdirectories.
Also, the kill.exe and tlist.exe programs in the w98 directory
came from diagnostic tools ftp site of Microsoft's.

# ssl_vncviewer: wrapper for vncviewer to use an stunnel SSL tunnel
# or an SSH tunnel.
#
# Copyright (c) 2006 by Karl J. Runge <runge@karlrunge.com>
#
# You must have stunnel(8) installed on the system and in your PATH
# (however, see the -ssh option below, in which case you will need ssh(1)
# installed) Note: stunnel is usually installed in an "sbin" subdirectory.
#
# You should have "x11vnc -ssl ..." or "x11vnc -stunnel ..."
# already running as the VNC server on the remote machine.
# (or use stunnel on the server side for any other VNC server)
#
#
# Usage: ssl_vncviewer [cert-args] host:display <vncviewer-args>
#
# e.g.: ssl_vncviewer snoopy:0
# ssl_vncviewer snoopy:0 -encodings "copyrect tight zrle hextile"
#
# [cert-args] can be:
#
# -verify /path/to/cacert.pem
# -mycert /path/to/mycert.pem
# -proxy host:port
#
# -verify specifies a CA cert PEM file (or a self-signed one) for
# authenticating the VNC server.
#
# -mycert specifies this client's cert+key PEM file for the VNC server to
# authenticate this client.
#
# -proxy try host:port as a Web proxy to use the CONNECT method
# to reach the VNC server (e.g. your firewall requires a proxy).
# For the "double proxy" case use -proxy host1:port1,host2:port2
#
# See http://www.karlrunge.com/x11vnc/#faq-ssl-ca for details on SSL
# certificates with VNC.
#
# A few other args (not related to SSL and certs):
#
# -ssh Use ssh instead of stunnel SSL. ssh(1) must be installed and you
# must be able to log into the remote machine via ssh.
#
# In this case "host:display" may be of the form "user@host:display"
# where "user@host" is used for the ssh login (see ssh(1) manpage).
#
# If -proxy is supplied it can be of the forms: "gwhost" "gwhost:port"
# "user@gwhost" or "user@gwhost:port". "gwhost" is an incoming ssh
# gateway machine (the VNC server is not running there), an ssh -L
# redir is used to "host" in "host:display" from "gwhost". Any "user@"
# part must be in the -proxy string (not in "host:display").
#
# Under -proxy use "gwhost:port" if connecting to any ssh port
# other than the default (22). (even for the non-gateway case,
# -proxy must be used to specify a non-standard ssh port)
#
# Examples:
#
# ssl_vncviewer -ssh bob@bobs-home.net:0
# ssl_vncviewer -ssh -sshcmd 'x11vnc -localhost' bob@bobs-home.net:0
#
# ssl_vncviewer -ssh -proxy fred@mygate.com:2022 mymachine:0
# ssl_vncviewer -ssh -proxy bob@bobs-home.net:2222 localhost:0
#
# -sshcmd cmd Run "cmd" via ssh instead of the default "sleep 15"
# e.g. -sshcmd 'x11vnc -display :0 -localhost -rfbport 5900'
#
# -sshargs "args" pass "args" to the ssh process, e.g. -L/-R port redirs.
#
# -sshssl Tunnel the SSL connection thru a SSH connection. The tunnel as
# under -ssh is set up and the SSL connection goes thru it. Use
# this if you want to have and end-to-end SSL connection but must
# go thru a SSH gateway host (e.g. not the vnc server). Or use
# this if you need to tunnel additional services via -R and -L
# (see -sshargs above).
#
# ssl_vncviewer -sshssl -proxy fred@mygate.com mymachine:0
#
#
# -alpha turn on cursor alphablending hack if you are using the
# enhanced tightvnc vncviewer.
#
# -grab turn on XGrabServer hack if you are using the enhanced tightvnc
# vncviewer (e.g. for fullscreen mode in some windowmanagers like
# fvwm that do not otherwise work in fullscreen mode)
#
#
# set VNCVIEWERCMD to whatever vncviewer command you want to use.
