NAME

       lts.conf - Main configuration file for LTSP

SYNOPSIS

       Any line beginning with a '#' is considered a comment. Options are of
       the format:

       VARIABLE=value

DESCRIPTION

       This file gets parsed when LTSP client starts up. The section defined
       by [default] gets applied to all clients, unless there is a
       specification for a particular client that overrides it. The per-client
       specs are prefixed by [<mac address>]

       You may also name an arbitrary section with a name, with settings
       underneath that section. You may then inherit that section with the
       LIKE variable. The Example section has an illustration of this.

       boolean values are specified by 'Y,y,True,true' for true and
       'N,n,False,false' for false

LTS.CONF - GENERAL PARAMETERS

       CONFIGURE_FSTAB
           boolean, default True

           /etc/fstab is generated by boot scripts

       CRONTAB_01..CRONTAB_10
           string, default unset

           A crontab line to add for a thin client.

       DNS_SERVER
           string, default unset

           A valid IP for domain name server Used to build the client's
           resolv.conf file. Not needed by default.

       SEARCH_DOMAIN
           string, default unset

           sets a valid search domain in the clients's resolv.conf file. Used
           to build the resolv.conf file. Not needed by default.

           Needed if DNS_SERVER is set

       LOCAL_APPS
           boolean default False

           Whether to run apps locally on the client or not

       LOCAL_APPS_EXTRAMOUNTS
           string, default unset

           This parameter enables extra mount points to be mounted on the thin
           client with sshfs. This require a commas separated list of
           directory.

       LOCALDEV
           boolean, default True

           This parameter enables local devices support, like CD's and USB
           sticks. Users plugging them in should see them on the desktop,
           after they've been allowed to access the FUSE subsystem on the
           server. Check your distibutions docs to see how this is done on
           your distribution.

       LOCALDEV_DENY_CD
           boolean, default False

           This parameter disables local device support for CD and DVD-rom
           devices.

       LOCALDEV_DENY_FLOPPY
           boolean, default False

           This parameter disables local device support for floppy devices.

       LOCALDEV_DENY_INTERNAL_DISKS
           boolean, default True

           This parameter disables local device support for internal ATA and
           SCSI hard disk devices.

       LOCALDEV_DENY_USB
           boolean, default False

           This parameter disables local device support for USB devices.

       LOCALDEV_DENY
           string, default unset

           This parameter disables local device support for devices matching
           certain patterns. Values are specified as a comma-separated list of
           sysfs attributes, which can be obtained by using udevadm info (or
           udevinfo). for example:

                                       udevadm info -q env -n /dev/hda
                                       ID_TYPE=disk
                                       ID_BUS=ata

           should return a list of the attributes relevent to /dev/hda. to
           exclude this disk and disks like it using LOCALDEV_DENY:
           LOCALDEV_DENY="ID_BUS:ata+ID_TYPE:disk" would match devices that
           were on the ata bus that were disks.

       NBD_SWAP
           boolean, default False

           Set this to True if you want to turn on NBD swap.

           If you enable this, you'll need to add the line:

                                       nbdswapd: ALL: keepalive

           to your /etc/hosts.allow file.

       NBD_SWAP_PORT
           integer, default 9572

           The port on which NBD swapping will occur. This is set to 9572 by
           default.

       NBD_SWAP_SERVER
           IP address, default SERVER

           The NBD swap server can exist on any server on the network that is
           capable of handling it. You can specify the IP address of that
           server. The default is whatever the value of SERVER set to.

       SERVER
           IP address, default unset

           This is the server that is used for the XDM_SERVER, TELNET_HOST,
           XFS_SERVER and SYSLOG_HOST, if any of those are not specified
           explicitly. If you have one machine that is acting as the server
           for everything, then you can just specify the address here and omit
           the other server parameters. If this value is not set, it will be
           auto detected as the machine that the thin client booted from.

       SYSLOG_HOST
           IP address, default unset

           If you want to send logging messages to a machine other than the
           default server, then you can specify the machine here. If this
           parameter is NOT specified, then it will use the SERVER parameter
           described above.

       USE_LOCAL_SWAP
           boolean, default False

           If you have a hard drive installed in the thin client, with a valid
           swap partition on it, this parameter will allow the thin client to
           swap to the local hard drive.

       TIMEZONE
           string, default unset

           The timezone code for the thin client to use.

       TIMESERVER
           IP address, default unset

           The address of an NTP time server that the thin client can set it's
           time from. If unset, the thin client just uses the BIOS time.

       SHUTDOWN_TIME
           string, format hh:mm:ss in 24 hour format, default unset

           Time at which thin client will automatically shut down.

LTS.CONF - SCRIPTS AND MODULES

       MODULE_01...MODULE_10
           string, default unset

           Up to 10 kernel modules can be loaded by using these configuration
           entries. The entire command line that you would use when running
           insmod can be specified here. For example:

               MODULE_01 = uart401.o
               MODULE_02 = "sb.o io=0x220 irq=5 dma=1"
               MODULE_03 = opl3.o

           If the value of this parameter is an absolute path name, then
           insmod will be used to load the module. Otherwise, modprobe will be
           used.

           In normal circumstances, you shouldn't need to specify anything
           here, as most hardware will be auto-detected.

       RCFILE_01...RCFILE_10
           A custom rc file, default unset

           Additional RC scripts can be executed by the ltsp-client-setup
           script. Just put the script in the /opt/ltsp/i386/etc/init.d
           directory, and specify the name of the script in one of these
           entries. Note that you must specify a full path, relative to the
           chroot. So, for example, if you have an RC file called
           /opt/ltsp/i386/etc/init.d/myrcfile, you'd specify:

               RCFILE_01=/etc/init.d/myrcfile

           In your lts.conf file.

LTS.CONF - PRINTER PARAMETERS

       PRINTER_0_DEVICE
           string, default unset

           The device name of the printer. Valid device names such as
           /dev/lp0, or /dev/usblp0 are allowed.

       PRINTER_0_PORT
           integer, default 9100

           The TCP/IP Port number to use for the print server.

       PRINTER_0_TYPE
           string, default unset

           Can either be set to P (for parallel), U (for USB) or S (for
           serial). Autodetected in most cases (except for serial).

       PRINTER_0_WRITE_ONLY
           boolean, default False

           Some parallel printers may need this set in order for the thin
           client to communicate to them properly. If you have problems with a
           parallel printer only printing part of the print job, try setting
           this to True.

       PRINTER_0_SPEED
           integer, default 9600

           Should be set to the baud rate of the printer (serial printers
           only).

       PRINTER_0_FLOWCTRL
           string, default unset

           Should be set to the flow control desired for the printer (serial
           printers only).

       PRINTER_0_PARITY
           boolean, default False

           Specifies whether parity should be enabled for the printer (serial
           printers only).

       PRINTER_0_DATABITS
           integer, default 8

           Specifies how many data bits for the printer (serial printers
           only).

       PRINTER_0_OPTIONS
           string, default unset

           Specifies specific options for the printer (serial printers only).

       LDM_PRINTER_LIST
           string, default unset

           Comma separated list of printers that will be displayed for that
           thin client (requires patched cups, included in Debian and Ubuntu).

       LDM_PRINTER_DEFAULT
           string, default unset

           Default printer for the thin client.

       SCANNER
           boolean, default unset

           This parameter enables scanners for the thin client.

LTS.CONF - KEYBOARD PARAMETERS

       CONSOLE_KEYMAP
           A valid console keymap, default en

           Allows you to specify a valid console keymap for TELNET_HOST
           sessions.

LTS.CONF TOUCHSCREEN PARAMETERS

       USE_TOUCH
           Enable touchscreen

           default <unset>, Enable touchscreen

           X_TOUCH_DEVICE     Path to device   /dev/ttyS0    set device for
                                                             touchscreen
           X_TOUCH_DRIVER     Touchscreen      elographics   set driver for
                              driver                         touchscreen

           X_TOUCH_MINY       integer          569           Ymin
           X_TOUCH_UNDELAY    integer          10            Untouch delay
           X_TOUCH_RTPDELAY   integer          10            Repeat touch
                                                             delay

SOUND AND VOLUME CONTROL PARAMETERS

       These parameters allow you to control the volume on the thin client.

       SOUND
           boolean, default True

           This parameter enables sound for the thin client.

       SOUND_DAEMON
           string, default pulse

           This parameter sets which sound daemon to use on the thin client.
           Values are esd, nasd, and pulse (default).

       VOLUME
           integer, default 90

           This represents an integer percentage of the volume, ranging from 0
           to 100%.

       HEADPHONE_VOLUME
           integer, default unset

           This represents an integer percentage of the headphone volume,
           ranging from 0 to 100%.

       PCM_VOLUME
           integer, default unset

           This represents an integer percentage of the PCM volume, ranging
           from 0 to 100%.

       CD_VOLUME
           integer, default unset

           This represents an integer percentage of the CD input volume,
           ranging from 0 to 100%.

       FRONT_VOLUME
           integer, default unset

           This represents an integer percentage of the front speaker volume,
           ranging from 0 to 100%.

       FRONT_VOLUME
           integer, default unset

           This represents an integer percentage of the front speaker volume,
           ranging from 0 to 100%.

       MIC_VOLUME
           integer, default unset

           This represents an integer percentage of the microphone input
           volume, ranging from 0 to 100%.

LTS.CONF - XORG PARAMETERS

       These parameters affect how Xorg behaves.

       USE_XFS
           boolean, default False

           Instructs the thin client to look at the XFS_SERVER option, and use
           XFS for serving fonts.

       XFS_SERVER
           IP address, default unset

           If you are using an X Font Server to serve fonts, then you can use
           this entry to specify the IP address of the host that is acting as
           the font server. If this is not specified, it will use the default
           server, which is specified with the SERVER entry described above.

       CONFIGURE_X
           If you want to be able to configure the individual settings of the
           X configuration file, without having the X automatically configure
           the graphics card for you, you must enable this option. By default
           this option is turned off. To turn it on do:

               CONFIGURE_X = True

           . You don't need this option just for keyboard and mouse settings.
           It corresponds to the graphic card and monitor options only.

       X_CONF
           string, default unset

           If you want to create your own complete X.org config file, you can
           do so and place it in the /opt/ltsp/<arch>/etc/X11 directory. Then,
           whatever you decide to call it needs to be entered as a value for
           this configuration variable. For example: X_CONF =
           /etc/X11/my-custom-xorg.conf Note that for the thin client, you
           reference it from /etc/X11.

       X_RAMPERC
           default '100', Percentage of RAM for X server

           Some programs allocate a large amount of ram in the X.org server
           running on your thin client. Programs like Firefox and Evince can
           use up so much ram, that they eventually exhaust all your physical
           ram, and NBD swap, causing your thin client to crash. If you find
           your clients being booted back to a login prompt, or freezing up
           when viewing certain PDF's or web pages, this may be the problem.

           The X_RAMPERC variable stands for X RAM PERCent, and is a number
           between 0 and 100 that specifies how much of the free space on your
           thin client X.org is allowed to consume. You'll generally want to
           set it at something lower than 100 percent, if you're having
           problems. Experimentation has shown a value between 80 and 90 will
           usually keep the terminal alive. What will then happen is the
           program consuming the memory will die, as opposed to the thin
           client itself. If you're having unexplained terminal problems,
           specifying:

           X_RAMPERC = 80

           in your lts.conf file may improve things.

       X_VIRTUAL
           string, default unset

           If you want to have a virtual screen which is larger than the
           physical screen on your thin client, you would configure that by
           providing a string of the form "width height" in this parameter,
           similar to the xorg.conf format.

       XDM_SERVER
           IP address, default unset

           If you're using the older startx screen script, and need to specify
           a different XDMCP server, then you can specify the server here. If
           this parameter is NOT specified, then it will use the SERVER
           parameter described above.

       XSERVER
           You can use this parameter to override which X server the thin
           client will run. For PCI and AGP video cards, this parameter should
           not be required. The thin client should normally be able to
           auto-detect the card.

           If, for some reason you do need to manually set it, here are some
           valid values:

           ark, ati, atimisc, chips, cirrus_alpine cirrus, cirrus_laguna,
           cyrix, dummy, fbdev fglrx, glint, i128, i740, i810, imstt, mga,
           neomagic, newport, nsc, nv, r128, radeon, rendition, riva128, s3,
           s3virge, savage, siliconmotion, sis, sisusb, tdfx, tga, trident,
           tseng, v4l, vesa, vga, via, vmware, voodoo

       X_MOUSE_DEVICE
           string, default unset

           This is the device node that the mouse is connected to. If it is a
           serial mouse, this would be a serial port, such as /dev/ttyS0 or
           /dev/ttyS1. This is not needed for PS/2 or USB mice, as they are
           auto-detected.

       X_MOUSE_PROTOCOL
           Should be auto-detected. However, valid entries include:

           sunkbd, lkkbd, vsxxxaa, spaceorb, spaceball, magellan, warrior,
           stinger, mousesystems, sunmouse, microsoft, mshack, mouseman,
           intellimouse, mmwheel, iforce, h3600ts, stowawaykbd, ps2serkbd,
           twiddler, twiddlerjoy

       X_MOUSE_EMULATE3BTN
           boolean, default unset

           Normally unset, may need to be set to Y for certain 2 button mice.

       X_NUMLOCK
           boolean, default False

           If this variable is set to True, then the numlock key will be
           defaulted to on when the terminal boots. Note that the numlockx
           command must be installed in the chroot for this to work.

       X_COLOR_DEPTH
           Integer: 2, 4, 8, 16, 24, 32 default 24

           This is the number of bits to use for the colour depth. Possible
           values are 8, 16, 24 and 32. 8 bits will give 256 colours, 16 will
           give 65536 colours, 24 will give 16 million colours and 32 bits
           will give 4.2 billion colours! Not all X servers support all of
           these values. The default value for this is 24.

       X_HORZSYNC
           min-max values

           This sets the X.org HorizSync configuration parameter. This should
           be auto-detected for your monitor, however, if you want to force a
           lower resolution, use this parameter to do so.

       X_VERTREFRESH
           min-max values

           This sets the X.org VertRefresh configuration parameter. This
           should be auto-detected for your monitor. If you need to force a
           lower resolution, use this parameter to do so.

       X_VIDEO_RAM
           string, default unset

           This sets the X.org VideoRam configuration parameter. The setting
           is in kilobytes. This should be auto-detected for your monitor. If
           you need to force a different video ram setting, use this parameter
           to do so.

       X_OPTION_01...X_OPTION_12
           A valid Device option

           This allows you to specify Option settings in the xorg.conf file,
           to add options to the video driver. A common use for this will be
           to test turning off acceleration in your driver, if you're having
           trouble. An example usage would be:

               X_OPTION_01 = "\"NoAccel\"" X_OPTION_02 = "\"AnotherOption\" \"True\""

           You probably won't need these except in special circumstances.

       X_MONITOR_OPTION_01...X_MONITOR_OPTION_10
           string, default unset

           A valid Monitor option, that would normally be used in an xorg.conf
           file.

       X_MODE_0, X_MODE_1, and X_MODE_2
           string, default unset

           These set the X.org ModeLine configuration. For example, if your
           thin client comes up in a higher resolution than what you want,
           say, 1280x1024, specifying:

               X_MODE_0 = 1024x768

           should get your desired resolution on startup.

           For drivers that support XRANDR, the XRANDR_MODE_* variabled are
           preferred. See the XRANDR section.

       X_BLANKING
           A positive integer

           When set, X_BLANKING will cause DPMS standby to activate after the
           number of seconds provided. If the monitor does not support DPMS,
           then the blanking screensaver will activate. If X_BLANKING is set
           to 0, the monitor will remain on indefinitely. NOTE: This does not
           apply to the xdmcp or startx screen script. Also, server-side
           Xclients such as power managers and screensavers may override this
           setting.

LTS.CONF OPTIONS - XRANDR OPTIONS

       XRANDR_DISABLE
           boolean, default False

           Disables XRANDR output handling so that the older X_MODE_0 way of
           setting resolution works. This is useful on older Xorg drivers that
           don't support XRANDR.

       XRANDR_OUTPUT_0 ... XRANDR_OUTPUT_8
           string, default unset

           Define xrandr output - can also be used for multihead positioning

       XRANDR_MODE_0 ... XRANDR_MODE_8
           string, default unset

           Valid video mode resolution. Sets mode for corresponding output.

       XRANDR_NEWMODE_0 ... XRANDR_NEWMODE_8
           string, default unset

           Specifies a valid modeline for a corresponding output.

       XRANDR_RATE_0 ... XRANDR_RATE_8
           string, default unset

           Sets refresh rate for the corresponding output.

       XRANDR_DPI_0 ... XRANDR_DPI_8
           string, default unset

           Sets the DPI for the corresponding output.

       XRANDR_ROTATE_0 ... XRANDR_ROTATE_8
           string, default unset

           Sets the rotation for the corresponding output.

       XRANDR_REFLECT_0 ... XRANDR_REFLECT_8
           string, default unset

           Sets the reflection for the corresponding output.

       XRANDR_SIZE_0 ... XRANDR_SIZE_8
           string, default unset

           Sets the resolution for the corresponding output (for xrandr <1.2).

       XRANDR_ORIENTATION_0 ... XRANDR_ORIENTATION_8
           string, default unset

           Sets the orientation for the corresponding output (for xrandr
           <1.2).

LTS.CONF OPTIONS - SCREEN SCRIPTS

       SCREEN_01...SCREEN_12
           string, default ldm

           Up to 12 screen scripts can be specified for a thin client. This
           will give you up to 12 sessions on the thin client, each accessible
           by pressing the Ctrl-Alt-F1 through Ctrl-Alt-F12 keys.

           Currently, possible values include: rdesktop, xdmcp, shell, ldm,
           startx (depreciated), and telnet

           Look in the $CHROOT/usr/share/ltsp/screen.d directory for more
           scripts, or write your own, and put them there.

       TELNET_HOST
           IP address, default unset

           If the thin client is setup to have a character based interface,
           then the value of this parameter will be used as the host to telnet
           into. If this value is NOT set, then it will use the value of
           SERVER above.

LTS.CONF OPTIONS - LDM OPTIONS

       LDM_AUTOLOGIN
           boolean, default False

           This option allows the thin client to login automatically without
           the need for a username and password. To set it set

               LDM_AUTOLOGIN = True

           for the corresponding thin client. This will attempt to log in the
           thin client with username = hostname and password = hostname. You
           can also set a user and password with LDM_USERNAME and LDM_PASSWORD
           variables.

       LDM_DEBUG
           boolean, default unset

           Turns on ldm debugging on the thin client. Log is written to
           /var/log/ldm.log on the thin client itself.

       LDM_DIRECTX
           boolean, default False

           This is arguably the most important LDM option, as it allows you to
           turn off the encrypted X tunnel via SSH, and instead run a less
           secure, but much faster unencrypted tunnel. Users who have slower
           thin clients will want to set this to True. It is set to True by
           default in Fedora.

       LDM_GUESTLOGIN
           boolean, default False

           This option places a GUEST LOGIN button underneath the entry field
           for username and password. To set it set

               LDM_GUESTLOGIN = True

           for the corresponding thin client. You can also set a user and
           password with

               LDM_USERNAME = John

           and

               LDM_PASSWORD = secret

           , although not setting these will default to the hostname of the
           thin client.

       LDM_ALLOW_USER
           string

           This option allows you to give access to certain thin clients based
           on the username set in /etc/passwd. For example, thin client A
           should only be used by Jane, Bob, and Fred, while thin client B is
           to be used by Harry only. By adding these options to the
           corresponding mac addresses you allow or deny access to the thin
           clients in question. Example:

               [thin:client:A:mac:address]
               LDM_ALLOW_USER = Jane,Bob,Fred
               [thin:client:B:mac:adddress]
               LDM_ALLOW_USER = Harry

       LDM_LOGIN_TIMEOUT
           integer

           This lets LDM automatically login after the set amount of time in
           seconds. If you specify this option, then do not specify
           LDM_AUTOLOGIN. Use it in this format:

               [thin:client:mac:address]
               LDM_LOGIN_TIMEOUT = 25

       LDM_USERNAME
           string, default unset

           This is the username that LDM will use for autologin.

       LDM_PASSWORD
           string, default unset

           This is the password that LDM will use for autologin.

       LDM_SYSLOG
           boolean, default False

           Normally, LDM logs to a simple file on the thin client, namely
           /var/log/ldm.log. This has the advantage of being fast, but the
           disadvantage of being hard to read for the administrator in the
           event of a problem, as the administrator must either spawn a shell
           screen session, or enable root login in tty1. By setting this
           option to "True", you can log up to the server if you've enabled
           your server's syslog for remote logging.

       LDM_LANGUAGE
           string, default unset

           This allows the system administrator to override the default locale
           settings on the server by setting the environment variables LANG,
           LANGUAGE and LC_ALL at login.

           Use the LANG variable to set the default locale for LDM's user
           interface.

       LDM_SSHOPTIONS
           string

           Allows you to specify custom options to the ssh sessions started
           between LDM and the server.

       NETWORK_COMPRESSION
           boolean, default False

           Enables compression of the SSH traffic over the network. Note that
           while this will reduce your network traffic, it will increase your
           cpu load.

       SSH_OVERRIDE_PORT
           integer, default unset

           If you run your ssh server different from the defult, you may set
           the port the thin client will use with this parameter.

       SSH_FOLLOW_SYMLINKS
           boolean, default True

           Causes sshfs mounted filesystems for local applications to follow
           symlinks. Should not need to be modified under normal
           circumstances.

       LDM_SESSION
           string, default unset

           Used to chose the default session on the server.

       LDM_XSESSION
           string, default Xsession

           Allows you to specify custom script on the server for LDM to run,
           rather than the server's standard script for starting an X session
           (usually Xsession).

LOCAL APPLICATIONS

       LOCAL_APPS
           boolean, default True

           Enables support for running local apps on the thin client.

       LOCAL_APPS_MENU
           boolean, default False

           Enables overriding of menu items from remote (server) applications.
           If this is set to True, local applications in the users menu will
           be used instead of the applications on the server.

       LOCAL_APPS_MENU_ITEMS
           string, default unset

           This item should contain a comma separated list of application
           names as they appear on their .desktop files.

       LOCAL_APPS_WHITELIST
           string, default unset

           Used to allow only specified space-separated commands to be run as
           local apps, allow all is default if unset. Full-paths are required
           for each command. No spaces in the names are allowed.
