sesman.ini(5)

NAME
sesman.ini - Configuration file for xrdp-sesman(8)

DESCRIPTION
sesman.ini consists of several sections. Each section starts with the section name in square brackets, followed by a list of parameter=value lines. Following sections are recognized:

[Globals]
    Global configuration

[Logging]
    Logging subsystem

[Sessions]
    Session management

[Security]
    Access control

[Chansrv]
    Settings for xrdp-chansrv(8)

[ChansrvLogging]
    Logging settings for xrdp-chansrv(8)

[SessionVariables]
    Environment variables for the session

All parameters and values (except for file names and paths) are case insensitive, and are described in detail below. If any parameter is specified more than once, the last entry will be used. Options specified outside their proper section will be ignored.

GLOBALS
Following parameters can be used in the [Globals] section.

ListenPort=path-to-socket
    UNIX domain socket for xrdp-sesman(8) to listen on.

    The default value of this setting is 'sesman.socket'.

    An absolute path can be specified by starting this parameter with a '/'. In this instance, the system administrator is responsible for ensuring the socket can only be created by a suitably privileged process.

    If the parameter does not start with a '/', a name within @socketdir@ is used.

EnableUserWindowManager=[true|false]
    If set to 1, true or yes, this option enables user specific startup script. That is, xrdp-sesman will execute the script specified by UserWindowManager if it exists.

UserWindowManager=filename
    Path of the startup script relative to the user's home directory. If present and enabled by EnableUserWindowManager, that script is executed instead of DefaultWindowManager.

DefaultWindowManager=filename
    Full path or relative path of the default startup script used by xrdp-sesman to start a session. If the path is not a full path, it will be resolved as relative path to @xrdpconfdir@. If not specified, defaults to @xrdpconfdir@/startwm.sh.

ReconnectScript=filename
    Full path or relative path if the script which executed when users reconnects to the existing session. If the path is not a full path, it will be resolved as relative path to @xrdpconfdir@. If not specified, defaults to @xrdpconfdir@/reconnectwm.sh.

LOGGING
Following parameters can be used in the [Logging] and [ChansrvLogging] sections.

LogFile=filename
    Log file path. It can be either absolute or relative. If not specified, defaults to ./sesman.log. If set to <stdout>, log will go to stdout. Use for debugging only It is ignored in the [ChansrvLogging] section since the channel server creates one log file per display and instead uses the following log file naming convention xrdp-chansrv.${DISPLAY}.log

LogLevel=level
    This option can have one of the following values: CORE or 0 - Log only core messages. Those messages are logged regardless of the selected logging level. ERROR or 1 - Log only error messages. WARNING, WARN or 2 - Logs warnings and error messages. INFO or 3 - Log 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 messages.

EnableSyslog=[true|false]
    If set to 1, true or yes, this option enables logging to syslog.

SyslogLevel=level
    Logging level for syslog. It can have the same values as LogLevel. Defaults to DEBUG.

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.

SESSIONS
Following parameters can be used in the [Sessions] section.

X11DisplayOffset=number
    The first X display number available for xrdp-sesman. This prevents xrdp-sesman from interfering with real X11 servers. If not specified, defaults to 10.

MaxSessions=number
    Sets the maximum number of simultaneous sessions. If not set or set to 0, unlimited session are allowed.

MaxDisplayNumber=number
    Sets the maximum number which can be assigned to an X11 $DISPLAY. The default is compatible with IANA TCP port allocations. If you are not allowing TCP connections to your X servers you may safely increase this number.

KillDisconnected=[true|false]
    If set to 1, true or yes, every session will be killed within DisconnectedTimeLimit seconds after the user disconnects. This setting currently only works with xorgxrdp sessions.

DisconnectedTimeLimit=number
    Sets the time limit for KillDisconnected to a value greater than 60. Values less than 60 are to be overridden with 60. This setting currently only works with xorgxrdp sessions.

IdleTimeLimit=number
    Sets the time limit (in seconds) before an idle session is disconnected. Idle means no keyboard inputs and no mouse moves/clicks here. If set to 0, idle sessions will never be disconnected by timeout. This works only with xorgxrdp sessions. Moreover, xorgxrdp must be v0.2.9 or later.

Policy=[Default|Separate|{UBDI}]
    Session allocation policy. Used to decide when to allocate a new session. Set to one of the following values:

    Default - Currently the same as "UB" for all session types

    Separate - All sessions are separate. Sessions can never be rejoined, and will need to be cleaned up manually, or automatically by setting other sesman options.

    Alternatively combine one-or-more of the following options

    U - Sessions are separated per user

    B - Sessions are separated by bits-per-pixel

    D - Sessions are separated by initial display size

    I - Sessions are separated by IP address

    Note that the U and B criteria cannot be turned off. DisplaySize refers to the initial geometry of a connection, as actual display sizes can change dynamically.

SECURITY
Following parameters can be used in the [Security] section.

AllowRootLogin=[true|false]
    If set to 1, true or yes, enables root login on the terminal server.

MaxLoginRetry=number
    The number of login attempts that are allowed on terminal server. If set to 0, unlimited attempts are allowed. If not specified, defaults to 3.

TerminalServerUsers=group
    Only the users belonging to the specified group are allowed to login on terminal server. If unset or set to an invalid or non-existent group, login for all users is enabled.

TerminalServerAdmins=group
    This option is currently ignored! Only members of this group can have session management rights.

RestrictOutboundClipboard=[all|none|text|file|image]
    If set to all, will restrict the clipboard outbound from the server, to prevent data copied inside the xrdp session to be pasted in the client. Default value is none. In addition, you can control text/file/image transfer restrictions respectively. It also accepts comma separated list such as text,file,image.
    none - No restriction about copying inbound clipboard data.
    all - Restrict to copy inbound clipboard data.
    text - Restrict to copy only inbound text clipboard data.
    file - Restrict to copy only inbound file clipboard data.
    image - Restrict to copy only inbound image clipboard data.
    To keep compatibility, the following aliases are also available.
    true - an alias of all.
    false - an alias of none.
    yes - an alias of all.

RestrictInboundClipboard=[none|all|text|file|image]
    If set to all, will restrict the clipboard inbound from the client, to prevent data copied inside the client to be pasted in the xrdp session. Default value is none. In addition, you can control text/file/image transfer restrictions respectively. It also accepts comma separated list such as text,file,image.
    none - No restriction about copying inbound clipboard data.
    all - Restrict to copy inbound clipboard data.
    text - Restrict to copy only inbound text clipboard data.
    file - Restrict to copy only inbound file clipboard data.
    image - Restrict to copy only inbound image clipboard data.
    To keep compatibility, the following aliases are also available.
    true - an alias of all.
    false - an alias of none.
    yes - an alias of all.

AlwaysGroupCheck=[true|false]
    If set to 1, true or yes, require group membership even if the group specified in TerminalServerUsers doesn't exist.

AllowAlternateShell=[true|false]
    If set to 0, false or no, prevent usage of alternate shells by users.

XorgNoNewPrivileges=[true|false]
    Only applicable on Linux. If set to 0, false or no, do not use the kernel's no_new_privs restriction when invoking the Xorg X11 server. The use of no_new_privs is intended to prevent issues due to a setuid Xorg executable. However, if a kernel security module (such as AppArmor) is used to confine xrdp, no_new_privs may interfere with transitions between confinement domains.

SessionSockdirGroup=group
    Sets the group owner of the directories containing session sockets. This is normally the GID of the xrdp process so xrdp can connect to user sessions.

X11 SERVER
Following parameters can be used in the [Xvnc] and [Xorg] sections.

param=string
    Multiple param lines are supported. This first line specifies the path to the X11 server executable. Following lines specify command line arguments passed to the X11 server.

CHANSRV
Following parameters can be used in the [Chansrv] section.

FuseMountName=string
    Directory for drive redirection. Created if it doesn't exist. If not specified, defaults to xrdp_client. If first character is not a '/', this is relative to $HOME.

    The following substitutions are made in this string:-
        %U - Username
        %u - Numeric UID
        %d - Numeric display number (ex 10)
        %D - Display environment variable (ex :10.0)
        %% - Percent character

    1) The directory path permissions MUST be configured correctly by the system administrator or the system itself - xrdp-chansrv will not do this for you (although it will create the final directories owned by the user).

    2) The desktop may not automatically display a link for the redirected drive. To fix this, consult the docs for your chosen desktop.

FileUmask=mode
    Additional umask to apply to files in the FuseMountName directory. The default value of 077 prevents other users on the system from reading files on your redirected drives. This may not be appropriate for all environments, and so you can change this value to allow other users to access your remote files if required.

EnableFuseMount=[true|false]
    Defaults to true. Set to false to disable xrdp-chansrv's use of the FUSE system feature, even if it has been built with this feature enabled.

    Setting this value to false will disable the following application features:-

    - drive redirection

    - copying-and-pasting of files

UseNautilus3FlistFormat=[false|true]
    Defaults to false. Set to true to make file copy-paste compatible with Nautilus from GNOME 3 versions later than 3.29.92. Do not use this for any other reason. This setting will be removed in a later version of xrdp, when GNOME 3 is no longer supported.

SoundNumSilentFramesAAC=number
    Sets the number of silent frames which are sent to client before close message is sent, when AAC is selected. If set to 0, no silent frame is sent. If not specified, defaults to 4.

SoundNumSilentFramesMP3=number
    Sets the number of silent frames which are sent to client before close message is sent, when MP3 is selected. If set to 0, no silent frame is sent. If not specified, defaults to 2.

SoundMsecDoNotSend=number
    Sets the duration(msec). Sound data is not send to client during number millisecond(s) after close message is sent, when AAC/MP3 is selected. If set to 0, all the data is sent. If not specified, defaults to 1000.

SESSIONS VARIABLES
All entries in the [SessionVariables] section are set as environment variables in the user's session.
