NAME

       ica - iTALC Client Application

SYNOPSIS

       ica [options]
       ica [options] [command]

DESCRIPTION

       ICA is the software which needs to run on clients in order to access them using iTALC master application.
       It provides a VNC server and a service daemon which is necessary for taking control over the client.

iTALC OPTIONS

       -role role

              Set role under which ICA should run where role  has  to  be  "teacher",  "admin",  "supporter"  or
              "other".

       -port port

              Set port at which the iTALC VNC server should listen. Default: 11100

       The -createkeypair option has been moved to the iTALC Management Console imc since iTALC 2.0.0.

X11VNC OPTIONS

       -noshm

              Do  not  use  the  MIT-SHM  extension for the polling.  Remote displays can be polled this way: be
              careful this can use large amounts of network bandwidth.  This is also of use if the local machine
              has a limited number of shm segments and -onetile is not sufficient.

       -onetile

              Do  not  use  the new copy_tiles() framebuffer mechanism, just use 1 shm tile for polling.  Limits
              shm segments used to 3.

       -nosel

               Do not manage exchange of X selection/cutbuffer between VNC viewers and the X server at all.

       -nosetclipboard

              Do not set the CLIPBOARD selection for changes received from VNC clients.

       -solid [color]

              To improve performance, when VNC clients are connected try to change the desktop background  to  a
              solid  color.  The [color] is optional: the default color is "cyan4".  For a different one specify
              the X color (rgb.txt name, e.g. "darkblue" or numerical "#RRGGBB").

              Currently  this  option only works on GNOME, KDE3,  CDE,  XFCE,  and  classic  X  (i.e.  with  the
              background  image  on  the  root  window).   The "gconftool-2", "dcop" and "xfconf-query" external
              commands are run for GNOME, KDE, and XFCE respectively.   (There   is   no   color  selection  for
              XFCE.)  Other desktops won't work, (send us the corresponding commands if you find them).

       -xrandr [mode]

              If   the  display  supports the XRANDR (X Resize, Rotate and Reflection) extension, and you expect
              XRANDR events to occur to the display while x11vnc  is  running,  this  options  indicates  x11vnc
              should  try to respond to them (as opposed to simply crashing by assuming  the  old  screen size).
              See the xrandr(1) manpage and run ´xrandr -q' for more info.  [mode]  is  optional  and  described
              below.

              Since   watching  for  XRANDR events and trapping errors increases polling overhead, only use this
              option if XRANDR changes are expected.  For example on a rotatable screen PDA or laptop, or  using
              a  XRANDR-aware  Desktop  where you resize often.  It is  best  to  be  viewing  with  a vncviewer
              that supports the NewFBSize encoding, since  it  knows  how  to  react  to  screen  size  changes.
              Otherwise,  LibVNCServer  tries  to  do  so  something  reasonable for viewers that cannot do this
              (portions of the screen may be clipped, unused, etc).

              "mode"  defaults  to  "resize",  which means create a  new,  resized,  framebuffer  and  hope  all
              viewers  can  cope  with  the  change.  "newfbsize" means first disconnect all viewers that do not
              support the NewFBSize VNC encoding, and then resize the framebuffer.   "exit"   means   disconnect
              all viewer clients, and then terminate x11vnc.
