* Prerequisites
** Operating System
Debian 5.0 "lenny" or Ubuntu 8.04 "Hardy Heron".
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 initrd.img 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 intended to be portable to other Unixes.
** 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/topic/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.gnu.org/software/gnutls/
+ Avahi 0.6.16 http://www.avahi.org/
+ Python 2.5 http://www.python.org/
+ Python-GnuTLS 1.1.5 http://pypi.python.org/pypi/python-gnutls/
+ dbus-python 0.82.4 http://dbus.freedesktop.org/doc/dbus-python/
+ python-ctypes 1.0.0 http://pypi.python.org/pypi/ctypes
+ PyGObject 2.14.2 http://library.gnome.org/devel/pygobject/
Strongly recommended:
+ fping 2.4b2-to-ipv6 http://www.fping.com/
Package names:
python-gnutls avahi-daemon python python-avahi python-dbus
python-ctypes python-gobject
*** Mandos Client
+ initramfs-tools 0.85i
http://packages.qa.debian.org/i/initramfs-tools.html
+ GnuTLS 2.4 http://www.gnu.org/software/gnutls/
+ Avahi 0.6.16 http://www.avahi.org/
+ GnuPG 1.4.9 http://www.gnupg.org/
+ GPGME 1.1.6 http://www.gnupg.org/related_software/gpgme/
Package names:
initramfs-tools libgnutls-dev libavahi-core-dev gnupg
libgpgme11-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 the correct network interface. The
default is "eth0", and if this needs to be adjusted, it will be
necessary to edit /etc/mandos/plugin-runner.conf to uncomment and
change the line there. If that file is changed, 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 invoke-rc.d 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 an hour 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, it is suggested that a more cryptographically
secure checker program is used and configured, since without IPsec
ping packets can be faked.
