This file documents the next steps to take after installation of the
2
Debian package, and also contain some notes specific to the Debian
3
packaging which are not also in the manual.

* Adding a Client Password to the Server

The server must be given a password to give back to the client on
16
20
is possible to verify that the correct password will be received by
17
21
this client by running the command, on the client:
19
/usr/lib/mandos/plugins.d/mandos-client \
23
MANDOSPLUGINHELPERDIR=/usr/lib/$(dpkg-architecture \
24
-qDEB_HOST_MULTIARCH)/mandos/plugin-helpers \
25
/usr/lib/$(dpkg-architecture -qDEB_HOST_MULTIARCH \
26
)/mandos/plugins.d/mandos-client \
20
27
--pubkey=/etc/keys/mandos/pubkey.txt \
21
--seckey=/etc/keys/mandos/seckey.txt; echo
28
--seckey=/etc/keys/mandos/seckey.txt \
29
--tls-privkey=/etc/keys/mandos/tls-privkey.pem \
30
--tls-pubkey=/etc/keys/mandos/tls-pubkey.pem; echo
23
32
This command should retrieve the password from the server, decrypt
24
33
it, and output it to standard output. There it can be verified to
36
45
automatically detected. If this should result in incorrect
37
46
interfaces, edit the DEVICE setting in the
38
47
"/etc/initramfs-tools/initramfs.conf" file. (The default setting is
39
empty, meaning it will autodetect the interface.) *If* the DEVICE
48
empty, meaning it will autodetect the interfaces.) *If* the DEVICE
40
49
setting is changed, it will be necessary to update the initrd image
41
by running the command
50
by running this command:
52
(For initramfs-tools:)
43
53
update-initramfs -k all -u
56
dpkg-reconfigure dracut
45
58
The device can also be overridden at boot time on the Linux kernel
46
59
command line using the sixth colon-separated field of the "ip="
47
60
option; for exact syntax, read the documentation in the file
48
"/usr/share/doc/linux-doc-*/Documentation/filesystems/nfsroot.txt",
61
"/usr/share/doc/linux-doc-*/Documentation/filesystems/nfs/nfsroot.txt",
49
62
available in the "linux-doc-*" package.
51
64
Note that since the network interfaces are used in the initial RAM
52
65
disk environment, the network interfaces *must* exist at that stage.
53
66
Thus, an interface can *not* be a pseudo-interface such as "br0" or
54
"tun0"; instead, only real interfaces (such as "eth0") can be used.
55
This can be overcome by writing a "network hook" program to create
56
an interface (see mandos-client(8mandos)) and placing it in
57
"/etc/mandos/network-hooks.d", from where it will be copied into the
58
initial RAM disk. Example network hook scripts can be found in
59
"/usr/share/doc/mandos-client/examples/network-hooks.d".
67
"tun0"; instead, only real interfaces (such as "enp1s0" or "eth0")
68
can be used. This can be overcome by writing a "network hook"
69
program to create an interface (see mandos-client(8mandos)) and
70
placing it in "/etc/mandos/network-hooks.d", from where it will be
71
copied into the initial RAM disk. Example network hook scripts can
72
be found in "/usr/share/doc/mandos-client/examples/network-hooks.d".

* User-Supplied Plugins
64
77
to the normal Mandos plugins. When adding or changing plugins, do
65
78
not forget to update the initital RAM disk image:
80
(For initramfs-tools:)
67
81
update-initramfs -k all -u
84
dpkg-reconfigure dracut
69
86
* Do *NOT* Edit "/etc/crypttab"
83
100
"mandos=connect:<IP_ADDRESS>:<PORT_NUMBER>" on the kernel command
86
For very advanced users, it it possible to specify simply
103
For very advanced users, it is possible to specify simply
87
104
"mandos=connect" on the kernel command line to make the system only
88
105
set up the network (using the data in the "ip=" option) and not pass
89
106
any extra "--connect" options to mandos-client at boot. For this to
90
107
work, "--options-for=mandos-client:--connect=<ADDRESS>:<PORT>" needs
91
108
to be manually added to the file "/etc/mandos/plugin-runner.conf".

* Diffie-Hellman Parameters
112
On installation, a file with Diffie-Hellman parameters,
113
/etc/keys/mandos/dhparams.pem, will be generated and automatically
114
installed into the initital RAM disk image and also used by the
115
Mandos Client on boot. If different parameters are needed for
116
policy or other reasons, simply replace the existing dhparams.pem
117
file and update the initital RAM disk image.
