.SH NAME
.I rdesktop
\- Remote Desktop Protocol client
.SH SYNOPSIS
.B rdesktop [options] server[:port]
.br
.SH DESCRIPTION
.I rdesktop
is a client for Remote Desktop Protocol (RDP), used in a number of Microsoft products.
It is known to work with Microsoft Windows server versions ranging from NT 4 terminal
server to Windows Server 2012 R2.

.SH OPTIONS
.TP
.BR "-u <username>"
Username for authentication on the server.
.TP
.BR "-d <domain>"
Domain for authentication.
.TP
.BR "-s <shell>"
Startup shell for the user - starts a specific application instead of Explore.
If SeamlessRDP is enabled this is the application which is started in seamless mode.
.TP
.BR "-c <directory>"
The initial working directory for the user.  Often used in combination with -s
to set up a fixed login environment.
.TP
.BR "-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).
.TP
.BR "-n <hostname>"
Client hostname.  Normally rdesktop automatically obtains the hostname of the
client.
.TP
.BR "-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.
.TP
.BR "-g <geometry>"
Desktop geometry (WxH[@DPI][+X[+Y]]). 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%", "-g 80%x70%".

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.

The optional DPI parameter should be specified if the screen rdesktop
is being displayed on is too far from 96 DPI for unscaled Windows to
be readable. Windows currently accepts values from 96 to 480.

Offset placement of window is optional. Starting point is upper left corner of screen.
Window manager might push into visible area, if a panel would be covered.
The schema is "-g <value>+<xoff>+<yoff>, f.e. "-g 30%+200+600".
.TP
.BR "-i"
Use password as smartcard pin. If a valid user certificate is matched in smart card
reader the password passed with \f-p\fR argument is used as pin for the smart card.
This feature also requires that smart card redirection is used using \f-r scard\fR argument.
.TP
.BR "-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.
.TP
.BR "-b"
Force the server to send screen updates as bitmaps rather than using
higher-level drawing operations.
.TP
.BR "-t"
Disable use of remote control. This will disable features like seamless connection
sharing.
.TP
.BR "-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 
\fIhttp://www.cendio.com/seamlessrdp/\fR.

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 command line 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.

.TP
.BR "-V <tls version>"
Set the Transport Level Security (also known as SSL) Version used.
Should be one of the following values: 1.0, 1.1, 1.2. By default all
versions are supported.
.TP
.BR "-B"
Use the BackingStore of the Xserver instead of the integrated one in
rdesktop.
.TP
.BR "-e"
Disable encryption.  This option is only needed (and will only work) if you
have a French version of NT TSE.
.TP
.BR "-E"
Disable encryption from client to server.  This sends an encrypted login packet,
but everything after this is unencrypted (including interactive logins).
.TP
.BR "-m"
Do not send mouse motion events.  This saves bandwidth, although some Windows
applications may rely on receiving mouse motion.
.TP
.BR "-M"
Use local X cursor inherited from window manager instead of server cursor. This
is mostly useful with -m, but is also useful if the server is sending bogus
mouse cursors.
.TP
.BR "-C"
Use private colourmap.  This will improve colour accuracy on an 8-bit display,
but rdesktop will appear in false colour when not focused.
.TP
.BR "-D"
Hide window manager decorations, by using MWM hints. 
.TP
.BR "-K"
Do not override window manager key bindings.  By default rdesktop attempts
to grab all keyboard input when it is in focus.
.TP
.BR "-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. 
.TP
.BR "-T <title>"
Sets the window title. The title must be specified using an UTF-8 string. 
.TP
.BR "-N"
Enable numlock synchronization 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. 
.TP
.BR "-X <windowid>"
Embed rdesktop-window in another window. The windowid is expected to
be decimal or hexadecimal (prefixed by 0x).
.TP
.BR "-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. 
.TP
.BR "-z"
Enable compression of the RDP datastream.
.TP
.BR "-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 hexadecimal
number containing the flags.
.TP
.BR "-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)
.TP
.BR "-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:
.TP
.BR "-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.
.TP
.BR "-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. 
.TP
.BR "-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.
.TP
.BR "-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.
.TP
.BR "-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).
.TP
.BR "-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.
.TP
.BR "-r scard[:<Scard Name>=<Alias Name>[;<Vendor Name>][,...]]"
Enables redirection of one or more smart-cards. You can provide
static name binding between GNU/Linux and Windows. To do this you
can use optional parameters as described: <Scard Name> - device name in
GNU/Linux and UNIX environment, <Alias Name> - device name shown in Windows environment
<Vendor Name> - optional device vendor name. For list of examples run
rdesktop without parameters.
.TP
.BR "-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'.
.TP
.BR "-0"
Attach to the console of the server (requires Windows Server 2003
or newer).
.TP
.BR "-4"
Use RDP version 4.
.TP
.BR "-5"
Use RDP version 5 (default).
.TP
.BR "-v"
Enable verbose output
.PP

.SH "CredSSP Smartcard options"
.TP
.BR "--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".
.TP
.BR "--sc-container-name <name>"
Specify the container name, usually this is the username for default container and it seems
like this is required to be specified for CredSSP authentication.
.TP
.BR "--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.
.TP
.BR "--sc-card-name <name>"
Specify the card name for example; "Telia EID IP5a".
