NAME
xrdp.ini - Configuration file for xrdp(8)
DESCRIPTION
This is the man page for xrdp.ini, xrdp(8) configuration file. It is composed by a number
of sections, each one composed by a section name, enclosed by square brackets, followed by
a list of <parameter>=<value> lines.
xrdp.ini supports the following sections:
[Globals] - sets some global configuration settings for xrdp(8).
[Logging] - logging subsystem parameters
[Channels] - channel subsystem parameters
All options and values (except for file names and paths) are case insensitive, and are
described in detail below.
GLOBALS
The options to be specified in the [Globals] section are the following:
autorun=session_name
Section name for automatic login. If set and the client supplies valid username and
password, the user will be logged in automatically using the connection specified
by session_name.
If session_name is empty, the LOGIN DOMAIN from the client with be used to select
the section. If no domain name is supplied, the first suitable section will be used
for automatic login.
bitmap_cache=[true|false]
If set to 1, true or yes this option enables bitmap caching in xrdp(8).
bitmap_compression=[true|false]
If set to 1, true or yes this option enables bitmap compression in xrdp(8).
bulk_compression=[true|false]
If set to 1, true or yes this option enables compression of bulk data in xrdp(8).
certificate=/path/to/certificate
key_file=/path/to/private_key
Set location of TLS certificate and private key. They must be written in PEM
format. If not specified, defaults to /etc/xrdp/cert.pem, /etc/xrdp/key.pem.
This parameter is effective only if security_layer is set to tls or negotiate.
channel_code=[true|false]
If set to 0, false or no this option disables all channels xrdp(8). See section
CHANNELS below for more fine grained options.
crypt_level=[low|medium|high|fips]
Regulate encryption level of Standard RDP Security. This parameter is effective
only if security_layer is set to rdp or negotiate.
Encryption in Standard RDP Security is controlled by two settings: Encryption Level
and Encryption Method. The only supported Encryption Method are 40BIT_ENCRYPTION
and 128BIT_ENCRYPTION. 56BIT_ENCRYPTION is not supported. This option controls the
Encryption Level:
low All data sent from the client to the server is protected by encryption
based on the maximum key strength supported by the client. This is the
only level that the traffic sent by the server to client is not encrypted.
medium All data sent between the client and the server is protected by encryption
based on the maximum key strength supported by the client (client
compatible).
high All data sent between the client and the server is protected by encryption
based on the server's maximum key strength (sever compatible).
fips All data sent between the client and server is protected using Federal
Information Processing Standard 140-1 validated encryption methods. This
level is required for Windows clients (mstsc.exe) if the client's group
policy enforces FIPS-compliance mode.
fork=[true|false]
If set to 1, true or yes for each incoming connection xrdp(8) forks a sub-process
instead of using threads.
hidelogwindow=[true|false]
If set to 1, true or yes, xrdp will not show a window for log messages. If not
specified, defaults to false.
max_bpp=[8|15|16|24|32]
Limit the color depth by specifying the maximum number of bits per pixel. If not
specified or set to 0, unlimited.
pamerrortxt=error_text
Specify text passed to PAM when authentication failed. The maximum length is 256.
port=port
Specify TCP port and interface to listen on for incoming connections. Specifying
only the port means that xrdp will listen on all interfaces. The default port for
RDP is 3389. Multiple address:port instances must be separated by spaces or
commas. Check the .ini file for examples. Specifying interfaces requires said
interfaces to be UP before xrdp starts.
require_credentials=[true|false]
If set to 1, true or yes, xrdp will scan the user name provided by the client for
the ASCII field separator character (0x1F). It will then copy over what is after
the separator as the password supplied by the user and treats it as autologon. If
not specified, defaults to false.
omain_user_separator=arator
If specified the domain name supplied by the client is appended to the username
separated by separator.
\nable_token_login=[true|false]
If set to 1, true or yes, xrdp requires clients to include username and password
initial connection phase. In other words, xrdp doesn't allow clients to show login
screen if set to true. If not specified, defaults to false.
security_layer=[tls|rdp|negotiate]
Regulate security methods. If not specified, defaults to negotiate.
tls Enhanced RDP Security is used. All security operations (encryption,
decryption, data integrity verification, and server authentication) are
implemented by TLS.
rdp Standard RDP Security, which is not safe from man-in-the-middle attack, is
used. The encryption level of Standard RDP Security is controlled by
crypt_level.
negotiate
Negotiate these security methods with clients.
ssl_protocols=[SSLv3] [TLSv1] [TLSv1.1] [TLSv1.2] [TLSv1.3]
Enables the specified SSL/TLS protocols. Each value should be separated by comma.
SSLv2 is always disabled. At least one protocol should be given to accept TLS
connections. This parameter is effective only if security_layer is set to tls or
negotiate.
tcp_keepalive=[true|false]
Regulate if the listening socket uses socket option SO_KEEPALIVE. If set to 1,
true or yes and the network connection disappears without closing messages, the
connection will be closed.
tcp_nodelay=[true|false]
Regulate if the listening socket uses socket option TCP_NODELAY. If set to 1, true
or yes, no buffering will be performed in the TCP stack.
tcp_send_buffer_bytes=buffer_size
tcp_recv_buffer_bytes=buffer_size
Specify send/recv buffer sizes in bytes. The default value depends on operating
system.
tls_ciphers=cipher_suite
Specifies TLS cipher suite. The format of this parameter is equivalent to which
openssl(1) ciphers subcommand accepts.
(ex. $ openssl ciphers 'HIGH:!ADH:!SHA1')
This parameter is effective only if security_layer is set to tls or negotiate.
use_fastpath=[input|output|both|none]
If not specified, defaults to none.
black=000000
grey=c0c0c0
dark_grey=808080
blue=0000ff
dark_blue=00007f
white=ffffff
red=ff0000
green=00ff00
background=000000
These options override the colors used internally by xrdp(8) to draw the login and
log windows. Colors are defined using a hexadecimal (hex) notation for the
combination of Red, Green, and Blue color values (RGB). The lowest value that can
be given to one of the light sources is 0 (hex 00). The highest value is 255 (hex
FF).
LOGGING
The following parameters can be used in the [Logging] section:
LogFile=/var/log/xrdp.log
This options contains the path to logfile. It can be either absolute or relative.
LogLevel=level
This option can have one of the following values:
CORE or 0 - Log only core messages. these messages are _always_ logged, regardless
the logging level selected.
ERROR or 1 - Log only error messages
WARNING, WARN or 2 - Logs warnings and error messages
INFO or 3 - Logs errors, warnings and informational messages
DEBUG or 4 - Log everything. If xrdp-sesman is compiled in debug mode, this options
will output many more low-level message, useful for developers
EnableSyslog=[true|false]
If set to 1, true or yes this option enables logging to syslog. Otherwise syslog is
disabled.
SyslogLevel=level
This option sets the logging level for syslog. It can have the same values of
LogLevel. If SyslogLevel is greater than LogLevel, its value is lowered to that of
LogLevel.
EnableConsole=[true|false]
If set to 1, true or yes, this option enables logging to the console (ie. stdout).
ConsoleLevel=level
Logging level for the console. It can have the same values as LogLevel. Defaults to
DEBUG.
EnableProcessId=[true|false]
If set to 1, true or yes, this option enables logging the process id in all log
messages. Defaults to false.
CHANNELS
The Remote Desktop Protocol supports several channels, which are used to transfer
additional data like sound, clipboard data and others. Channel names not listed here will
be blocked by xrdp. Not all channels are supported in all cases, so setting a value to
true is a prerequisite, but does not force its use.
Channels can also be enabled or disabled on a per connection basis by prefixing each
setting with channel. in the channel section.
rdpdr=[true|false]
If set to 1, true or yes using the RDP channel for device redirection is allowed.
rdpsnd=[true|false]
If set to 1, true or yes using the RDP channel for sound is allowed.
drdynvc=[true|false]
If set to 1, true or yes using the RDP channel to initiate additional dynamic
virtual channels is allowed.
cliprdr=[true|false]
If set to 1, true or yes using the RDP channel for clipboard redirection is
allowed.
rail=[true|false]
If set to 1, true or yes using the RDP channel for remote applications integrated
locally (RAIL) is allowed.
xrdpvr=[true|false]
If set to 1, true or yes using the RDP channel for XRDP Video streaming is allowed.
CONNECTIONS
A connection section is made of a section name, enclosed in square brackets, and the
following entries:
name=<session name>
The name displayed in xrdp(8) login window's combo box.
lib=../vnc/libvnc.so
Sets the library to be used with this connection.
username=<username>|{base64}<base64-encoded-username>|ask
Specifies the username used for authenticating in the connection. If set to ask,
user name should be provided in the login window.
If the username includes comment out symbols such as '#', or ';', the username can
be provided in base64 form prefixing "{base64}".
password=<password>|{base64}<base64-encoded-password>|ask
Specifies the password used for authenticating in the connection. If set to ask,
password should be provided in the login window.
This parameter can be provided in base64 form as well as username. See also
examples below.
ip=127.0.0.1
Specifies the ip address of the host to connect to.
port=<number>|-1
Specifies the port number to connect to. If set to -1, the default port for the
specified library is used.
xserverbpp=<number>
Specifies color depth of the backend X server. The default is the color depth of
the client. Only Xvnc and X11rdp use that setting. Xorg runs at 24 bpp.
disabled_encodings_mask=<number>
Set this bitmask to a non-zero value to prevent xrdp(8) requesting some features
from the Xvnc server. You should only need to set this to a non-zero value to work
around bugs in your Xvnc server. The bit values supported for a particular release
of xrdp(8) are documented in xrdp.ini.
code=<number>|0
Specifies the session type. The default, 0, is Xvnc, 10 is X11rdp, and 20 is Xorg
with xorgxrdp modules.
chansrvport=DISPLAY(n)|/path/to/domain-socket
Asks xrdp to connect to a manually started xrdp-chansrv instance. This can be
useful if you wish to use to use xrdp to connect to a VNC session which has been
started other than by xrdp-sesman, as you can then make use of xrdp-chansrv
facilities in the VNC session.
The first form of this setting is recommended, replacing n with the X11 display
number of the session.
