* Prerequisites

** Operating System

   Debian 6.0 "squeeze" or Ubuntu 10.10 "Maverick Meerkat" (or later).

   This is mostly for the support scripts which make sure that the

   client is installed and started in the initial RAM disk environment

   and that the initial RAM file system image file is automatically

   made unreadable.  The server and client programs themselves *could*

   be run in other distributions, but they *are* specific to GNU/Linux

   systems, and are not written with portabillity to other Unixes in

   mind.

** Libraries

   The following libraries and packages are needed.  (It is possible

   that it might work with older versions of some of these, but these

   versions are confirmed to work.  Newer versions are almost

   certainly OK.)

*** Documentation

    These are required to build the manual pages for both the server

    and client:

    + DocBook 4.5         http://www.docbook.org/

      Note: DocBook 5.0 is not compatible.

    + DocBook XSL stylesheets 1.71.0

                         http://wiki.docbook.org/DocBookXslStylesheets

    Package names:

    docbook docbook-xsl

    To build just the documentation, run the command "make doc".  Then

    the manual page "mandos.8", for example, can be read by running

    "man -l mandos.8".

*** Mandos Server

    + GnuTLS 2.4          http://www.gnutls.org/

      Note: GnuTLS 3 will only work with Python-GnuTLS 2

    + Avahi 0.6.16        http://www.avahi.org/

    + Python 2.7          https://www.python.org/

    + Python-GnuTLS 1.1.5 https://pypi.python.org/pypi/python-gnutls/

    + dbus-python 0.82.4  http://dbus.freedesktop.org/doc/dbus-python/

    + PyGObject 2.14.2    https://developer.gnome.org/pygobject/

    + pkg-config  http://www.freedesktop.org/wiki/Software/pkg-config/

    + Urwid 1.0.1         http://urwid.org/

      (Only needed by the "mandos-monitor" tool.)

    Strongly recommended:

    + fping 2.4b2-to-ipv6      http://www.fping.org/

    + ssh-keyscan from OpenSSH http://www.openssh.com/

    Package names:

    python-gnutls avahi-daemon python python-avahi python-dbus

    python-gobject python-urwid pkg-config fping ssh-client

*** Mandos Client

    + initramfs-tools 0.85i

                        https://tracker.debian.org/pkg/initramfs-tools

    + GnuTLS 2.4        http://www.gnutls.org/

    + Avahi 0.6.16      http://www.avahi.org/

    + GnuPG 1.4.9       https://www.gnupg.org/

    + GPGME 1.1.6       https://www.gnupg.org/related_software/gpgme/

    + pkg-config  http://www.freedesktop.org/wiki/Software/pkg-config/

    Strongly recommended:

    + OpenSSH           http://www.openssh.com/

    Package names:

    initramfs-tools libgnutls-dev libavahi-core-dev gnupg

    libgpgme11-dev pkg-config ssh

* Installing the Mandos server

  1. Do "make doc".

  2. On the computer to run as a Mandos server, run the following

     command:

     For Debian: su -c 'make install-server'

     For Ubuntu: sudo make install-server

     (This creates a configuration without any clients configured; you

     need an actually configured client to do that; see below.)

* Installing the Mandos client.

  1. Do "make all doc".

  2. On the computer to run as a Mandos client, run the following

     command:

     For Debian: su -c 'make install-client'

     For Ubuntu: sudo make install-client

     This will also create an OpenPGP key, which will take some time

     and entropy, so be patient.

  3. Run the following command:

     For Debian: su -c 'mandos-keygen --password'

     For Ubuntu: sudo mandos-keygen --password

     When prompted, enter the password/passphrase for the encrypted

     root file system on this client computer.  The command will

     output a section of text, starting with a [section header].  Copy

     and append this to the file "/etc/mandos/clients.conf" *on the

     server computer*.

  4. Configure the client to use any special configuration needed for

     your local system.  Note: This is not necessary if the server is

     present on the same wired local network as the client.  If you do

     make changes to /etc/mandos/plugin-runner.conf, the initrd.img

     file must be updated, possibly using the following command:

	# update-initramfs -k all -u

  5. On the server computer, start the server by running the command

     For Debian: su -c 'invoke-rc.d mandos start'

     For Ubuntu: sudo service mandos start

     At this point, it is possible to verify that the correct password

     will be received by the client by running the command:

	# /usr/lib/mandos/plugins.d/mandos-client \

		--pubkey=/etc/keys/mandos/pubkey.txt \

		--seckey=/etc/keys/mandos/seckey.txt; echo

     This command should retrieve the password from the server,

     decrypt it, and output it to standard output.

     After this, the client computer should be able to reboot without

     needing a password entered on the console, as long as it does not

     take more than five minutes to reboot.

* Further customizations

  You may want to tighten or loosen the timeouts in the server

  configuration files; see mandos.conf(5) and mandos-clients.conf(5).

  If IPsec is not used and SSH is not installed, it is suggested that

  a more cryptographically secure checker program is used and

  configured, since, without IPsec, ping packets can be faked.
