NAME

       ssvnc - a GUI wrapper for SSL and SSH VNC connections.

SYNOPSIS

       ssvnc
       ssvnc [host][:display]
       ssvnc [saved-profile-name]
       ssvnc [options] [host-or-profile]
       ssvnc -cmd [ssvnc_cmd-args]
       ssvnc -viewer [viewer-args]
       ssvnc --help

DESCRIPTION

       ssvnc  is  a tcl/tk gui wrapper that runs on Unix, MacOSX, and Windows.  It sets up an SSL
       or SSH tunnel to the remote VNC Server and then launches the VNC viewer  (either  the  one
       provided  or  another one that you have specified) to use that encrypted tunnel to connect
       to the VNC  Server.   The  use  of  Proxies  and  Gateways  to  make  the  connections  is
       implemented.

       Once  you  have  started  the  SSVNC gui, you can click on the buttons "Help", "Options ->
       Help", "Certs -> Help", etc. for much information on how to use and configure the tool.

       In short, you supply a VNC server "hostname:display" in the "VNC Host:Display"  entry  box
       and  then  press  the  "Connect"  button to connect to the server via SSL (stunnel).  E.g.
       "far-away.east:0".  Port numbers are also allowed, e.g. far-away.east:5905.

       Or supply user@hostname:display and  click  on  the  "Use  SSH"  option,  then  press  the
       "Connect" button to connect to the server via an SSH tunnel.  E.g. "fred@far-away.east:0".

       Note  it  is  also  possible  to  disable the use of SSL/SSH encryption tunnels by using a
       vnc:// or Vnc:// prefix before host:display.  Shift+Ctrl-E is a  short-cut  to  add/remove
       it.  See also the -noenc option below for the 'No Encryption' button.

       Normally  you  do  not specify any command line options.  You simply run ssvnc and use the
       GUI that starts up.

       However, as shortcuts you can supply a VNC host:display (or host:port) on the command line
       to  connect  to  immediately  (the  GUI  is started and the connection is initiated).  For
       example, "ssvnc far-away.east:0" Instead of a  host:display, you can specify the name of a
       saved  profile  to  automatically  load  that profile and then connect to its server.  For
       example "ssvnc far", if you named the profile "far".  You can use the -profiles option  to
       list the profiles you have saved.

       The related commands sshvnc and tsvnc start up the GUI in simplified modes: SSH Only Mode,
       and Terminal Services Mode, respectively.  See below and the  application  Help  for  more
       information on the modes.

       You  can also place certain settings in your ~/.ssvncrc, see the SSVNC Help panel ('Tips')
       for more info.

       The -cmd option does not start the  GUI,  it  runs  the  command  line  utility  ssvnc_cmd
       directly with the given arguments.  ssvnc_cmd can launch the viewer directly (-viewer ...)
       or, by default, the ss_vncviewer SSL/SSH tunnel wrapper script.  See its help  output  for
       more information.

       There are also some command line options described as follows.

OPTIONS

       -help, -h
              Prints out to the terminal a brief description and the options.

       --help Starts  up  the  GUI  as though the 'Help' button was pressed to show the main Help
              panel.

       -cmd [ssvnc_cmd-args]
              Launch the ssvnc_cmd utility command directly (no GUI)  with  the  given  arguments
              (for use when ssvnc_cmd is not in one's PATH.) If neither ssvnc_cmd nor ssvncviewer
              is in PATH, one can launch the viewer directly via:  ssvnc  -cmd  -viewer  [viewer-
              args] See the next option -viewer for an alias.

       -viewer [viewer-args]
              Shorthand for ssvnc -cmd -viewer [viewer-args].

       -profiles
              List  the  saved  SSVNC profiles you have created.  A profile is a destination host
              with specific parameter settings.

       -list  Same as -profiles

       -ssh   Start in "SSH Only Mode".  No SSL aspects are shown.  Same as running  the  command
              sshvnc

       -ts    Start  in  "Terminal Services Mode".  This is like "SSH Only Mode", but simpler and
              assumes x11vnc is available on the remote side  to  start  and  manage  X  and  VNC
              sessions.  Same as running the command tsvnc

       -tso   Same  as  -ts  "Terminal Services Mode", however never let the user leave this mode
              (no button to switch modes is provided.)  Same as SSVNC_TS_ALWAYS=1.

       -ssl   Force the full GUI Mode: both SSL and SSH.  This is the default.  Same as -ss.

       -nv    Toggle the "Verify All Certs" button to be off at startup.

       -nvb   Never show the "Verify All Certs" button.  Same as SSVNC_NO_VERIFY_ALL_BUTTON=1.

       -bigger
              Make the Profile Selection Dialog window bigger.  Same as SSVNC_BIGGER_DIALOG=1.

       -noenc Start off in a mode where a 'No Encryption'  check  button  is  present.   You  can
              toggle the mode with Ctrl-E.  Same as SSVNC_DISABLE_ENCRYPTION_BUTTON=1. Or noenc=1
              in ~/.ssvncrc.  Selecting no encryption is  the  same  as  the  vnc://  and  Vnc://
              prefixes  described below.  The -noenc mode is now the default, use -enc or noenc=0
              for the opposite behavior.

       -killstunnel
              On Windows, automatically terminate the  STUNNEL  process  when  the  viewer  exits
              instead  of  prompting  you (same as killstunnel=1 in ssvnc_rc or toggle in Options
              menu)

       -nokillstunnel
              On Windows, disable -killstunnel mode.  Same as killstunnel=0 in ssvnc_rc or toggle
              in Options menu.  Note that -killstunnel mode is now the default.

       -mycert /path/to/mycert.pem
              Set  the  default  "MyCert" to be /path/to/mycert.pem.  Same as -cert.  If the file
              does  not  exist,  ~/.vnc/certs  is  prefixed  and  tried.   You   can   also   set
              mycert=/path/to/mycert.pem in ~/.ssvncrc.

       -cacert /path/to/cacert.crt
              Set  the default "ServerCert" to be /path/to/cacert.crt.  Same as -ca.  If the file
              does  not  exist,  ~/.vnc/certs  is  prefixed  and  tried.   You   can   also   set
              cacert=/path/to/cacert.crt in ~/.ssvncrc.

       -crl /path/to/mycrl.pem
              Set  the default Certificate Revocation List to be /path/to/mycrl.pem.  If the file
              does  not  exist,  ~/.vnc/certs  is  prefixed  and  tried.   You   can   also   set
              crl=/path/to/mycrl.pem in ~/.ssvncrc.

URL NOTATION

       Here  are  all  of  our  URL-like  prefixes  that you can put in front of host:display (or
       host:port):

       For SSL:  vncs:// vncssl:// and vnc+ssl://

       For SSH:  vncssh:// and vnc+ssh://

       For No Encryption:  vnc:// and Vnc://

       Examples:

       To quickly make an SSL connection: ssvnc vncs://snoopy.com:0

       To quickly make an SSH connection: ssvnc vnc+ssh://fred@snoopy.com:0

       To quickly make a direct connection: ssvnc Vnc://snoopy.com:0

       The above will also work in the "VNC Host:Display"  entry  box  in  the  GUI.   Press  the
       "Connect" button after entering them.

       The  difference  between  vnc://  and  Vnc://  is  that the latter one will not prompt you
       whether you really want to make an unencrypted connection or not.

FILES

       Your SSVNC vnc profiles are stored in the  $HOME/.vnc/profiles  directory.   They  end  in
       suffix .vnc

       Your  SSVNC  vnc certificates and keys are stored in the $HOME/.vnc/certs directory.  They
       typically end in .pem (both certificate and private key) or .crt (certificate only).

       You can put a few  global  parameters  (e.g.  mode=sshvnc)  in  your  $HOME/.ssvncrc  file
       (ssvnc_rc on Windows); see the application Help for more information.

FONTS

       The following is from Tip 18 in the Help panel.

       Fonts:  To  change the tk fonts, set these environment variables before starting up ssvnc:
       SSVNC_FONT_DEFAULT and SSVNC_FONT_FIXED.  For example:

       % env SSVNC_FONT_DEFAULT='helvetica -20 bold' ssvnc

       % env SSVNC_FONT_FIXED='courier -14' ssvnc

       or set both of them at once.

       To achieve the same effect, you can also set  parameters  in  your  ~/.ssvncrc  file,  for
       example:

       font_default=helvetica -20 bold

       font_fixed=courier -14
