       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 Explore.  If
              SeamlessRDP is enabled this is the application which i started in seamless mode.

       -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.

       -i     Use password as smartcard pin. If a valid user certificate is matched in smart card
              reader the password passed with p argument is used as pin for the smart card.  This
              feature also requires that smart card redirection is used using r scard argument.

       -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.

       -t     Disable use of remote control. This will disable features like seamless  connection

       -A <seamlessrdpshell>
              Enable  SeamlessRDP  by  specifying  the path to seamless rdp shell.  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 normally specify a startup shell which  launches
              the desired application through SeamlessRDP.

              Example:    rdesktop    -A   'c:\seamlessrdp\seamlessrdpshell.exe'   -s   'notepad'

              Any subsequential call to the above  commandline  example  will  make  use  of  the
              seamless  connection  sharing  feature  which spawns another notepad in the current
              connection to the specified server and then exit.

       -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, 24 or 32).  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, 30MB for 24-bit colour and 40MB for 32-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).

CredSSP Smartcard options

       --sc-csp-name <name>
              Specify the CSP (Crypto Service Provider) to  use  on  the  windows  side  for  the
              smartcard  authentication.  CSP  is the driver for your smartcard and it seems like
              this is required to be specified for CredSSP authentication. For swedish NetID  the
              following CSP name is used; "Net iD - CSP".

       --sc-container-name <name>
              Specify  the  container name, usally this is the username for default container and
              it seems like this is required to be specified for CredSSP authentication.

       --sc-reader-name <name>
              Specify the reader name to be used to prevent the pin code being sent to wrong card
              if there are several readers.

       --sc-card-name <name>
              Specify the card name for example; "Telia EID IP5a".
