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.
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 client.
-k <layout>
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 is en-us (a US keyboard).
-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%".
-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.
-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.
-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.
-z
Enable
compression of the RDP datastream. This currently only works for a colour
depth of 8bpp.
-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 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).
-0
Attach to the console of the server (requires Windows
Server 2003 or newer).
