# ssl_tightvncviewer:
#
# A wrapper that calls ssl_vncviewer to use the enhanced TightVNC viewer.
#
# The enhanced TightVNC viewer features are:
#
# - SSL support for connections using the co-bundled stunnel program.
# - rfbNewFBSize VNC support (screen resizing)
# - cursor alphablending with x11vnc at 32bpp
# - xgrabserver support for fullscreen mode (for old window mgrs)
#
#
# Your platform (e.g. Linux.i686) is autodetected and enhanced
# vncviewer and stunnel binaries for it are used (see the ./bin directory).
#
# See the build.unix script if your platform is not in this package.
# You can also set the env. var. UNAME=os.arch to any "os.arch" you want
# to override the autodetetion.
#
# Usage:
#
# ssl_tightvncviewer [ssl_vncviewer-args] hostname:N [tightvncviewer-args]
#
# "hostname:N" is the host and VNC display to connect to, e.g. snoopy:0
#
# See the script util/ssl_vncviewer for details about its arguments:
#
# -verify pemfile
# -mycert pemfile
# -proxy phost:pport
# -alpha
# -grab
#
#
# If the *very first* argument is "-cotvnc" then it is assumed you are on
# Darwin and want to run the Chicken of the VNC viewer via our wrapper.
#
#
# See the TightVNC viewer documentation for on its cmdline arguments.
#
# For convenience, here is the current (7/2006) TightVNC viewer -help output:
#
# TightVNC viewer version 1.3dev5
#
# Usage: vncviewer [<OPTIONS>] [<HOST>][:<DISPLAY#>]
# vncviewer [<OPTIONS>] [<HOST>][::<PORT#>]
# vncviewer [<OPTIONS>] -listen [<DISPLAY#>]
# vncviewer -help
#
# <OPTIONS> are standard Xt options, or:
# -via <GATEWAY>
# -shared (set by default)
# -noshared
# -viewonly
# -fullscreen
# -noraiseonbeep
# -passwd <PASSWD-FILENAME> (standard VNC authentication)
# -user <USERNAME> (Unix login authentication)
# -encodings <ENCODING-LIST> (e.g. "tight copyrect")
# -bgr233
# -owncmap
# -truecolour
# -depth <DEPTH>
# -compresslevel <COMPRESS-VALUE> (0..9: 0-fast, 9-best)
# -quality <JPEG-QUALITY-VALUE> (0..9: 0-low, 9-high)
# -nojpeg
# -nocursorshape
# -x11cursor
# -autopass
#
# Option names may be abbreviated, e.g. -bgr instead of -bgr233.
# See the manual page for more information.

#
# 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
# (the first CONNECT is done through host1:port1 to host2:port2
# and then a 2nd CONNECT to the destination VNC server.)
#
# 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)
#
# A "double ssh" can be specified via a -proxy string with the two
# hosts separated by a comma:
#
# [user1@]host1[:port1],[user2@]host2[:port2]
#
# in which case a ssh to host1 and thru it via a -L redir a 2nd
# ssh is established to host2.
#
# 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
#
# ssl_vncviewer -ssh -proxy fred@gw-host,fred@peecee 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.
