The list of software bundled in the archive files:
TightVNC Viewer (windows, unix, macosx)
Chicken of the VNC Viewer (macosx)
Stunnel (windows, unix, macosx)
Putty/Plink/Pageant (windows)
OpenSSL (windows)
esound (windows)
These are all self-contained in the bundle directory: they will not be
installed on your system. Just un-zip or un-tar the file you downloaded
and run it straight from its directory.
Quick Start:
-----------
Unix and Mac OS X:
Inside a Terminal do something like the following.
Unpack the archive:
% gzip -dc ssvnc-1.0.8.tar.gz | tar xvf -
Run the GUI:
% ./ssvnc/Unix/ssvnc (for Unix)
% ./ssvnc/MacOSX/ssvnc (for Mac OS X)
actually both of the above are equivalent, and the same as running
% ./ssvnc/bin/ssvnc
The smaller file "ssvnc_no_windows-1.0.8.tar.gz"
could have been used as well.
Windows:
Unzip, using WinZip or a similar utility, the zip file:
ssvnc-1.0.8.zip
Run the GUI, e.g.:
- Sets up any additional SSH port redirections that you want.
Start -> Run -> Browse
and then navigate to
Your package should have included binaries for many OS's: Linux, Solaris,
FreeBSD, etc. Unpack your archive and see the subdirectories of
.../ssvnc/Windows/ssvnc.exe
select Open, and then OK to launch it.
The smaller file "ssvnc_windows_only-1.0.8.zip"
could have been used as well.
You can make a Windows shortcut to this program if you want to.
See the Windows/README.txt for more info.
Bundle Info:
------------
The bundle files unpack a directory/folder named: ssvnc
It contains these programs to launch the GUI:
Windows/ssvnc.exe for Windows
MacOSX/ssvnc for Mac OS X
Unix/ssvnc for Unix
(the Mac OS X and Unix launchers are simply links to the bin directory).
Your bundle file should have included binaries for many OS's: Linux,
Solaris, FreeBSD, etc. Unpack your archive and see the subdirectories of

./bin/tightvncviewer -h output for how to override platform autodection
./bin/ssvnc_cmd -h output for how to override platform autodection
via the UNAME env. var).
External Dependencies:
----------------------
On Windows everything is included. Let us know if you find otherwise.
On Unix depending on what you do you need these programs installed:
- basic unix utilities (sh, ls, cat, awk, sed, etc..)
- tcl/tk (wish interpreter)
- xterm
- perl
- ssh
- openssl
Lesser used ones: netcat, esd/artsd, smbclient, smbmount, cups

Then click on "Connect". When you do so the STUNNEL program will be
started locally to provide you with an outgoing SSL tunnel.
Once the STUNNEL is running, the TightVNC Viewer will be automatically

Once the STUNNEL is running, the TightVNC Viewer (Or Chicken-of-the-VNC
on Mac OS X) will be automatically started directed to the local SSL
tunnel which, in turn, encrypts and redirects the connection to the
remote VNC server.
The remote VNC server must support an initial SSL handshake before
using the VNC protocol (i.e. VNC is tunnelled through the SSL channel
after it is established). "x11vnc -ssl ..." does this, and any VNC
server can be made to do this by using, e.g., STUNNEL on the remote side.
Click on "Options ..." if you want to use an *SSH* tunnel instead of
SSL (then the VNC Server does not need to speak SSL or use STUNNEL).
Note that on Windows when the Viewer connection is finished you may
need to terminate STUNNEL manually from the System Tray (right click
on dark green icon) and selecting "Exit".

Remote SSH Command:
In SSH or SSH and SSL mode you can also specify a remote command to run
on the remote ssh host in the "Remote SSH Command" entry. The default
is just to sleep a bit (sleep 30) to make sure the port tunnels are
active. Alternatively you could have the remote command start the
VNC server, e.g. x11vnc -nopw -display :0 -rfbport 5900 -localhost
You can also specify the remote SSH command by putting a string like
cmd=x11vnc -nopw -display :0 -rfbport 5900 -localhost
(use any command you wish to run) at the END of the VNC Host:Display
entry. In general, you can cram it all in the VNC Host:Display if
you like: host:disp proxy:port cmd=... (this is the way it is
stored internally).
SSL Certificates:
If you want to use a SSL Certificate (PEM) file to authenticate yourself
to the VNC server ("MyCert") or to verify the identity of the VNC Server
("ServerCert" or "CertsDir") select the certificate file by clicking
the "Certs ..." button before connecting.
Certificate verification is needed to prevent Man In the Middle attacks.
