* Prerequisites
** Operating System
Debian 8.0 "jessie" or Ubuntu 15.10 "Wily Werewolf" (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 3.3 https://www.gnutls.org/
(but not 3.6.0 or later, until 3.6.6, which works)
+ Avahi 0.6.16 https://www.avahi.org/
+ Python 3 https://www.python.org/
Note: Python 2.7 is still supported, if the "mandos",
"mandos-ctl", and "mandos-monitor" files are edited to contain
"#!/usr/bin/python" instead of python3.
+ dbus-python 0.82.4 https://dbus.freedesktop.org/doc/dbus-python/
+ PyGObject 3.8 https://wiki.gnome.org/Projects/PyGObject
+ pkg-config https://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:
avahi-daemon python3 python3-dbus python3-gi python3-urwid
pkg-config fping ssh-client
*** Mandos Client
+ GNU C Library 2.17 https://gnu.org/software/libc/
+ GnuTLS 3.3 https://www.gnutls.org/
(but not 3.6.0 or later, until 3.6.6 which works)
+ Avahi 0.6.16 https://www.avahi.org/
+ GnuPG 1.4.9 https://www.gnupg.org/
+ GPGME 1.1.6 https://www.gnupg.org/related_software/gpgme/
+ pkg-config https://www.freedesktop.org/wiki/Software/pkg-config/
+ libnl-route 3 https://www.infradead.org/~tgr/libnl/
+ GLib 2.40 http://www.gtk.org/
One of:
+ initramfs-tools 0.85i
https://tracker.debian.org/pkg/initramfs-tools
+ dracut 044+241
http://www.kernel.org/pub/linux/utils/boot/dracut/dracut.html
Strongly recommended:
+ OpenSSH http://www.openssh.com/
Package names:
initramfs-tools dracut libgnutls-dev gnutls-bin libavahi-core-dev
gnupg libgpgme11-dev pkg-config ssh libnl-route-3-dev
libglib2.0-dev
* 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 \
--tls-privkey=/etc/keys/mandos/tls-privkey.pem \
--tls-pubkey=/etc/keys/mandos/tls-pubkey.pem; 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.
