2. On the computer to run as a Mandos server, run the following
66
command: "sudo make install-server".

(This creates a configuration without any clients configured; we

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

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

* Installing the Mandos client.

81
1. Do "make all doc".
75
83
2. On the computer to run as a Mandos client, run the following
76
command: "sudo make install-client". This will also create an
77
OpenPGP key, which will take some time and entropy, so either
78
wait patiently or frob your mouse until it's done.
80
3. Run "mandos-keygen --password". When prompted, enter the
81
password/passphrase for the encrypted root file system on this
82
client computer. It will output a section of text, starting with
83
a [section header]. Copy and paste this into the file
84
"/etc/mandos/clients.conf" *on the server computer*.
86
4. On the server computer, start the server by running the command
87
"invoke-rc.d mandos start".
85
For Debian: su -c 'make install-client'
86
For Ubuntu: sudo make install-client
88
This will also create an OpenPGP key, which will take some time
89
and entropy, so be patient.
91
3. Run the following command:
92
For Debian: su -c 'mandos-keygen --password'
93
For Ubuntu: sudo mandos-keygen --password
95
When prompted, enter the password/passphrase for the encrypted
96
root file system on this client computer. The command will
97
output a section of text, starting with a [section header]. Copy
98
and append this to the file "/etc/mandos/clients.conf" *on the
101
4. Configure the client to use the correct network interface. The
102
default is "eth0", and if this needs to be adjusted, it will be
103
necessary to edit /etc/mandos/plugin-runner.conf to uncomment and
104
change the line there. If that file is changed, the initrd.img
105
file must be updated, possibly using the following command:
107
# update-initramfs -k all -u
109
5. On the server computer, start the server by running the command
110
For Debian: su -c 'invoke-rc.d mandos start'
111
For Ubuntu: sudo invoke-rc.d mandos start
113
At this point, it is possible to verify that the correct password
114
will be received by the client by running the command:
116
# /usr/lib/mandos/plugins.d/mandos-client \
117
--pubkey=/etc/keys/mandos/pubkey.txt \
118
--seckey=/etc/keys/mandos/seckey.txt; echo
120
This command should retrieve the password from the server,
121
decrypt it, and output it to standard output.
123
After this, the client computer should be able to reboot without
124
needing a password entered on the console, as long as it does not
125
take more than an hour to reboot.
