.SH "NAME"
\fBxrdp.ini\fR \- Configuration file for \fBxrdp\fR(8)
.SH "DESCRIPTION"
This is the man page for \fBxrdp.ini\fR, \fBxrdp\fR(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 \fI<parameter>\fR=\fI<value>\fR lines.
\fBxrdp.ini\fR supports the following sections:
.TP
\fB[Globals]\fP \- sets some global configuration settings for \fBxrdp\fR(8).
.TP
\fB[Logging]\fP \- logging subsystem parameters

.SH "GLOBALS"
The options to be specified in the \fB[Globals]\fR section are the following:
.TP
\fBautorun\fP=\fIsession_name\fP
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 \fIsession_name\fP.
If \fIsession_name\fP is empty, the \fBLOGIN DOMAIN\fR 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.

If set to \fB1\fR, \fBtrue\fR or \fByes\fR this option enables compression of bulk data in \fBxrdp\fR(8).
.TP
\fBcertificate\fP=\fI/path/to/certificate\fP
.TP
\fBkey_file\fP=\fI/path/to/private_key\fP
Set location of TLS certificate and private key. They must be written in PEM format.
If not specified, defaults to \fB@sysconfdir@/xrdp/cert.pem\fP, \fB@sysconfdir@/xrdp/key.pem\fP.
This parameter is effective only if \fBsecurity_layer\fP is set to \fBtls\fP or \fBnegotiate\fP.
.TP
\fBchannel_code\fP=\fI[true|false]\fP
If set to \fB0\fR, \fBfalse\fR or \fBno\fR this option disables all channels \fBxrdp\fR(8).

.TP
\fBcrypt_level\fP=\fI[low|medium|high|fips]\fP
.\" <http://blogs.msdn.com/b/openspecification/archive/2011/12/08/encryption-negotiation-in-rdp-connection.aspx>
Regulate encryption level of Standard RDP Security.
This parameter is effective only if \fBsecurity_layer\fP is set to \fBrdp\fP or \fBnegotiate\fP.
Encryption in Standard RDP Security is controlled by two settings: \fIEncryption Level\fP
and \fIEncryption Method\fP. The only supported \fIEncryption Method\fP are \fB40BIT_ENCRYPTION\fP
and \fB128BIT_ENCRYPTION\fP. \fB56BIT_ENCRYPTION\fP is not supported.
This option controls the \fIEncryption Level\fP:
.RS 8
.TP
.B low
All data sent from the client to the server is protected by encryption based on
the maximum key strength supported by the client.
.I This is the only level that the traffic sent by the server to client is not encrypted.
.TP
.B 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).
.TP
.B high
All data sent between the client and the server is protected by encryption based on
the server's maximum key strength (sever compatible).
.TP
.B fips
All data sent between the client and server is protected using Federal Information
Processing Standard 140-1 validated encryption methods.
.I This level is required for Windows clients (mstsc.exe) if the client's group policy
.I enforces FIPS-compliance mode.
.RE
.TP
\fBfork\fP=\fI[true|false]\fP
If set to \fB1\fR, \fBtrue\fR or \fByes\fR for each incoming connection \fBxrdp\fR(8) forks a sub-process instead of using threads.
.TP
\fBhidelogwindow\fP=\fI[true|false]\fP
If set to \fB1\fP, \fBtrue\fP or \fByes\fP, \fBxrdp\fP will not show a window for log messages.
If not specified, defaults to \fBfalse\fP.
.TP
\fBmax_bpp\fP=\fI[8|15|16|24|32]\fP
Limit the color depth by specifying the maximum number of bits per pixel.
If not specified or set to \fB0\fP, unlimited.
.TP
\fBpamerrortxt\fP=\fIerror_text\fP
Specify text passed to PAM when authentication failed. The maximum length is \fB256\fP.
.TP
\fBport\fP=\fIport\fP
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 \fB3389\fP.
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.
.TP
\fBrequire_credentials\fP=\fI[true|false]\fP
If set to \fB1\fP, \fBtrue\fP or \fByes\fP, \fBxrdp\fP will scan the user name provided by the

defaults to \fBfalse\fP.
.TP
\domain_user_separator\fP=\separator\fP
If specified the domain name supplied by the client is appended to the username separated
by \fBseparator\fP.
.TP
\enable_token_login\fP=\fI[true|false]\fP
If set to \fB1\fP, \fBtrue\fP or \fByes\fP, \fBxrdp\fP 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 \fBfalse\fP.
.TP
\fBsecurity_layer\fP=\fI[tls|rdp|negotiate]\fP
Regulate security methods. If not specified, defaults to \fBnegotiate\fP.

.RE
.TP
\fBssl_protocols\fP=\fI[SSLv3] [TLSv1] [TLSv1.1] [TLSv1.2] [TLSv1.3]\fP
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 \fBsecurity_layer\fP is set to \fBtls\fP or \fBnegotiate\fP.
.TP
\fBtcp_keepalive\fP=\fI[true|false]\fP
Regulate if the listening socket uses socket option \fBSO_KEEPALIVE\fP.

.TP
\fBtcp_send_buffer_bytes\fP=\fIbuffer_size\fP
.TP
\fBtcp_recv_buffer_bytes\fP=\fIbuffer_size\fP
Specify send/recv buffer sizes in bytes. The default value depends on operating system.
.TP
\fBtls_ciphers\fP=\fIcipher_suite\fP
Specifies TLS cipher suite. The format of this parameter is equivalent
to which \fBopenssl\fP(1) ciphers subcommand accepts.
(ex. $ openssl ciphers 'HIGH:!ADH:!SHA1')
This parameter is effective only if \fBsecurity_layer\fP is set to \fBtls\fP or \fBnegotiate\fP.
