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.
