# 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.
|
||||
#

||||

# 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:
|
||||
