       rdesktop - Remote Desktop Protocol client


       rdesktop [options] server[:port]


       rdesktop  is  a  client  for  Remote Desktop Protocol (RDP), used in a number of Microsoft
       products including Windows NT Terminal Server, Windows 2000 Server, Windows XP and Windows
       2003 Server.


       -u <username>
              Username for authentication on the server.

       -d <domain>
              Domain for authentication.

       -s <shell>
              Startup shell for the user - starts a specific application instead of Explorer.

       -c <directory>
              The  initial  working directory for the user.  Often used in combination with -s to
              set up a fixed login environment.

       -p <password>
              The password to authenticate with.  Note that this may have no  effect  if  "Always
              prompt  for password" is enabled on the server.  WARNING: if you specify a password
              on the command line it may be visible to other users when they use tools  like  ps.
              Use -p - to make rdesktop request a password at startup (from standard input).

       -n <hostname>
              Client  hostname.   Normally  rdesktop  automatically  obtains  the hostname of the

       -k <keyboard-map>
              Keyboard layout to emulate.  This  requires  a  corresponding  keymap  file  to  be
              installed.   The  standard keymaps provided with rdesktop follow the RFC1766 naming
              scheme: a language code followed by a country code if necessary - e.g.  en-us,  en-
              gb, de, fr, sv, etc.

              The  default  keyboard map depends on the current locale (LC_* and LANG environment
              variables). If the current locale is unknown, the default keyboard map is en-us  (a
              US English keyboard).

              The  keyboard  maps  are  file names, which means that they are case sensitive. The
              standard keymaps are all in lowercase.

              The keyboard maps are searched relative to the directories $HOME/.rdesktop/keymaps,
              KEYMAP_PATH  (specified  at  build  time),  and  $CWD/keymaps,  in  this order. The
              keyboard-map argument can also be an absolute filename.

              The special value `none' can be used instead of a  keyboard  map.   In  this  case,
              rdesktop  will  guess  the scancodes from the X11 event key codes using an internal
              mapping method. This method only supports the basic alphanumeric keys and  may  not
              work properly on all platforms so its use is discouraged.

       -g <geometry>
              Desktop  geometry  (WxH).  If geometry is the special word "workarea", the geometry
              will be fetched from the extended window manager hints property _NET_WORKAREA, from
              the  root  window.  The geometry can also be specified as a percentage of the whole
              screen, e.g. "-g 80%".

              If the specified geometry depends on the  screen  size,  and  the  screen  size  is
              changed,  rdesktop  will  automatically  reconnect  using the new screen size. This
              requires that rdesktop has been compiled with RandR support.

       -f     Enable fullscreen mode.  This overrides the window manager and causes the  rdesktop
              window  to  fully  cover the current screen.  Fullscreen mode can be toggled at any
              time using Ctrl-Alt-Enter.

       -b     Force the server to send screen updates as bitmaps rather than  using  higher-level
              drawing operations.

       -A     Enable  SeamlessRDP. In this mode, rdesktop creates a X11 window for each window on
              the server side. This mode requires the SeamlessRDP server side component, which is
              available  from   When  using this option, you
              should specify a startup shell  which  launches  the  desired  application  through

              Example: rdesktop -A -s 'seamlessrdpshell notepad'.

       -B     Use the BackingStore of the Xserver instead of the integrated one in rdesktop.

       -e     Disable  encryption.  This option is only needed (and will only work) if you have a
              French version of NT TSE.

       -E     Disable encryption from client to server.  This sends an  encrypted  login  packet,
              but everything after this is unencrypted (including interactive logins).

       -m     Do  not  send  mouse  motion  events.   This saves bandwidth, although some Windows
              applications may rely on receiving mouse motion.

       -C     Use private colourmap.  This will improve colour accuracy on an 8-bit display,  but
              rdesktop will appear in false colour when not focused.

       -D     Hide window manager decorations, by using MWM hints.

       -K     Do  not override window manager key bindings.  By default rdesktop attempts to grab
              all keyboard input when it is in focus.

       -S <button size>
              Enable single application mode. This option can be  used  when  running  a  single,
              maximized application (via -s). When the minimize button of the windows application
              is pressed, the rdesktop window is minimized instead of the remote application. The
              maximize/restore button is disabled. For this to work, you must specify the correct
              button size, in pixels. The special word "standard" means 18 pixels.

       -T <title>
              Sets the window title. The title must be specified using an UTF-8 string.

       -N     Enable numlock syncronization between the Xserver and the remote RDP session.  This
              is  useful  with  applications  that  looks  at  the numlock state, but might cause
              problems with some Xservers like Xvnc.

       -X <windowid>
              Embed rdesktop-window in another window. The windowid is expected to be decimal  or
              hexadecimal (prefixed by 0x).

       -a <bpp>
              Sets  the  colour  depth for the connection (8, 15, 16 or 24).  More than 8 bpp are
              only supported when connecting to Windows XP (up to 16 bpp) or  newer.   Note  that
              the colour depth may also be limited by the server configuration. The default value
              is the depth of the root window.

       -z     Enable compression of the RDP datastream.

       -x <experience>
              Changes default bandwidth performance behaviour for RDP5. By default  only  theming
              is  enabled, and all other options are disabled (corresponding to modem (56 Kbps)).
              Setting experience to b[roadband] enables menu animations and full window dragging.
              Setting  experience  to  l[an]  will  also  enable  the  desktop wallpaper. Setting
              experience to m[odem] disables all (including themes). Experience  can  also  be  a
              hexidecimal number containing the flags.

       -P     Enable  caching  of  bitmaps  to  disk  (persistent bitmap caching). This generally
              improves performance (especially on low bandwidth connections) and reduces  network
              traffic  at  the  cost  of  slightly longer startup and some disk space.  (10MB for
              8-bit colour, 20MB for 15/16-bit colour and 30MB for 24-bit colour sessions)

       -r <device>
              Enable redirection of the specified device on the client, such that it  appears  on
              the  server.  Note  that  the  allowed redirections may be restricted by the server

              Following devices are currently supported:

       -r comport:<comport>=<device>,...
              Redirects serial devices on your client to the server. Note that  if  you  need  to
              change  any settings on the serial device(s), do so with an appropriate tool before
              starting rdesktop. In most OSes you  would  use  stty.  Bidirectional/Read  support
              requires  Windows XP or newer.  In Windows 2000 it will create a port, but it's not
              seamless, most shell programs will not work with it.

       -r disk:<sharename>=<path>,...
              Redirects a path to  the  share  \\tsclient\<sharename>  on  the  server  (requires
              Windows XP or newer). The share name is limited to 8 characters.

       -r lptport:<lptport>=<device>,...
              Redirects  parallel  devices  on  your  client  to  the server.  Bidirectional/Read
              support requires Windows XP or newer. In Windows 2000 it will create  a  port,  but
              it's not seamless, most shell programs will not work with it.

       -r printer:<printername>[=<driver>],...
              Redirects  a  printer  queue  on the client to the server. The <printername> is the
              name of the queue in your local system. <driver> defaults  to  a  simple  PS-driver
              unless  you  specify  one.  Keep  in  mind that you need a 100% match in the server
              environment, or the driver will fail. The first printer on the command line will be
              set as your default printer.

       -r sound:[local|off|remote]
              Redirects sound generated on the server to the client. "remote" only has any effect
              when you connect to the console with the -0 option. (Requires Windows XP or newer).

       -r lspci
              Activates the lspci channel, which allows the server to enumerate the  clients  PCI
              devices. See the file lspci-channel.txt in the documentation for more information.

       -r scard[:<Scard Name>=<Alias Name>[;<Vendor Name>][,...]]
              Enables redirection of one or more smart-cards. You can provide static name binding
              between linux and windows. To do this you can use optional parameters as described:
              <Scard  Name>  -  device  name in Linux/Unix enviroment, <Alias Name> - device name
              shown in Windows enviroment <Vendor Name> - optional device vendor name.  For  list
              of examples run rdesktop without parameters.

       -r clipboard:[off|PRIMARYCLIPBOARD|CLIPBOARD]
              Enable   clipboard  redirection.  'PRIMARYCLIPBOARD'  looks  at  both  PRIMARY  and
              CLIPBOARD when sending data to server. 'CLIPBOARD' looks at only CLIPBOARD.

       -0     Attach to the console of the server (requires Windows Server 2003 or newer).

       -4     Use RDP version 4.

       -5     Use RDP version 5 (default).
