# tightvncviewer:
|
|
#
|
|
# A wrapper that calls 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 if
|
|
# you want to build one.
|
|
#
|
|
# See the build.unix script if your platform is not in this package if you want to build one.
|
|
# You can also set the env. var. UNAME=os.arch to any "os.arch" you want
|
|
# to override the autodetetion.
|
|
#
|
|
# Usage:
|
|
#
|
|
# tightvncviewer [tightvncviewer-args] hostname:N
|
|
# or
|
|
# tightvncviewer -ssl hostname:N [tightvncviewer-args]
|
|
#
|
|
# "hostname:N" is the host and VNC display to connect to, e.g. snoopy:0
|
|
#
|
|
# 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.
|
|
#
|
|
# If the next argument is "-ssl" then ssl_tightvncviewer is called
|
|
# instead. See that script for details.
|
|
#
|
|
# 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
