NAME
rdesktop - Remote Desktop Protocol client
SYNOPSIS
rdesktop [options] server[:port]
DESCRIPTION
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.
OPTIONS
-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 client.
-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 sharing.
-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
http://www.cendio.com/seamlessrdp/.
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' mywts.domain.com
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
- 3 - Formatted: November 14, 2024

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 configuration.
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.
-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
