       ltsp - entry point to Linux Terminal Server Project applets


       ltsp  [-b base-dir] [-h] [-m home-dir] [-o overwrite] [-t tftp-dir] [-V] [applet] [applet-


       Run the specified LTSP applet with applet-options. To get  help  with  applets  and  their
       options, run `man ltsp applet` or `ltsp --help applet`.


       The following applets are currently defined:

              • dnsmasq: configure dnsmasq for LTSP

              • image: generate a squashfs image from an image source

              • info: gather support information about the LTSP installation

              • initrd: create the ltsp.img initrd add-on

              • ipxe: install iPXE binaries and configuration in TFTP

              • kernel: copy the kernel and initrd from an image to TFTP

              • nfs: configure NFS exports for LTSP

       LTSP  clients  also  have some additional applets, like initrd-bottom, init and login, but
       they're not runnable by the user.


       LTSP directories can be configured by passing one or more of the following parameters, but
       it's  recommended  that  an  /etc/ltsp/ltsp.conf configuration file is created instead, so
       that you don't have to pass them in each ltsp command.

       -b, --base-dir=/srv/ltsp
              This is where the chroots, squashfs images and virtual  machine  symlinks  are;  so
              when you run ltsp kernel img_name, it will search either for a squashfs image named
              /srv/ltsp/images/img_name.img, or for a chroot named /srv/ltsp/img_name, if it's  a
              directory  that  contains /proc. Additionally, ltsp image img_name will also search
              for a symlink to a VM disk  named  /srv/ltsp/img_name.img.  $BASE_DIR  is  exported
              read-only by NFSv3, so do not put sensitive data there.

       -h, --help
              Display a help message.

       -m, --home-dir=/home
              The  default  method  of  making /home available to LTSP clients is SSHFS.  In some
              cases security isn't an issue, and sysadmins prefer the insecure NFSv3  speed  over
              SSHFS.  $HOME_DIR  is  used  by  ltsp  nfs to export the correct directory, if it's
              different to /home, and by LTSP clients to mount it.

       -o, --overwrite[=0|1]
              Overwrite existing files. Defaults to 1  as  administrators  are  not  supposed  to
              manually  edit  LTSP  autogenerated files, but maintain local content into separate
              files (e.g. /etc/exports.d/local.exports). If you manually maintain  ltsp.ipxe,  it
              might be a good idea to set OVERWRITE=0 in ltsp.conf.

       -t, --tftp-dir=/srv/tftp
              LTSP  places the kernels, initrds and iPXE files in /srv/tftp/ltsp, to be retrieved
              by the clients via the TFTP protocol. The TFTP server of dnsmasq and tftpd-hpa  are
              configured to use /srv/tftp as the TFTP root.

       -V, --version
              Display the version information.


              All  the  long  options  can  also  be  specified  as  variables  in  the ltsp.conf
              configuration file in UPPER_CASE, using underscores instead of hyphens.


       All the long options can also be specified as environment  variables  in  UPPER_CASE,  for

              BASE_DIR=/opt/ltsp ltsp kernel ...


       The following are the typical commands to install and maintain LTSP in chrootless mode:

              # To install:
              ltsp image /
              ltsp dnsmasq
              ltsp nfs
              ltsp ipxe

              # To update the exported image, after changes in the server software:
              ltsp image /

       The following are the typical commands to provide an additional x86_32 image, assuming one
       uses VirtualBox. If you specifically name it x86_32, then the ltsp.ipxe code automatically
       prefers it for 32bit clients:

              ln -rs $HOME/VirtualBox\ VMs/x86_32/x86_32-flat.vmdk /srv/ltsp/x86_32.img
              ltsp image x86_32
              ltsp ipxe
