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 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.

-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".
