* Choose the Client Network Interface
3
Please make sure that the correct network interface is specified in
4
the DEVICE setting in the "/etc/initramfs-tools/initramfs.conf"
5
file. If the setting is empty, the interface will be autodetected
6
at boot time, which may not be correct. *If* the DEVICE setting is
7
changed, it will be necessary to update the initrd image by running
10
update-initramfs -k all -u
12
The device can be overridden at boot time on the Linux kernel
13
command line using the sixth colon-separated field of the "ip="
14
option; for exact syntax, read the documentation in the file
15
"/usr/share/doc/linux-doc-*/Documentation/filesystems/nfsroot.txt",
16
available in the "linux-doc-*" package.
18
Note that since this network interface is used in the initial RAM
19
disk environment, the network interface *must* exist at that stage.
20
Thus, the interface can *not* be a pseudo-interface such as "br0" or
21
"tun0"; instead, a real interface (such as "eth0") must be used.

Debian package, and also contain some notes specific to the Debian

packaging which are not also in the manual.

* Adding a Client Password to the Server
38
20
is possible to verify that the correct password will be received by
39
21
this client by running the command, on the client:
41
/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 \
42
27
--pubkey=/etc/keys/mandos/pubkey.txt \
43
28
--seckey=/etc/keys/mandos/seckey.txt; echo
46
31
it, and output it to standard output. There it can be verified to
47
32
be the correct password, before rebooting.
36
If it ever should be necessary, the Mandos client can be temporarily
37
prevented from running at startup by passing the parameter
38
"mandos=off" to the kernel.
40
* Specifying a Client Network Interface
42
At boot time the network interfaces to use will by default be
43
automatically detected. If this should result in incorrect
44
interfaces, edit the DEVICE setting in the
45
"/etc/initramfs-tools/initramfs.conf" file. (The default setting is
46
empty, meaning it will autodetect the interface.) *If* the DEVICE
47
setting is changed, it will be necessary to update the initrd image
48
by running the command
50
update-initramfs -k all -u
52
The device can also be overridden at boot time on the Linux kernel
53
command line using the sixth colon-separated field of the "ip="
54
option; for exact syntax, read the documentation in the file
55
"/usr/share/doc/linux-doc-*/Documentation/filesystems/nfs/nfsroot.txt",
56
available in the "linux-doc-*" package.
58
Note that since the network interfaces are used in the initial RAM
59
disk environment, the network interfaces *must* exist at that stage.
60
Thus, an interface can *not* be a pseudo-interface such as "br0" or
61
"tun0"; instead, only real interfaces (such as "eth0") can be used.
62
This can be overcome by writing a "network hook" program to create
63
an interface (see mandos-client(8mandos)) and placing it in
64
"/etc/mandos/network-hooks.d", from where it will be copied into the
65
initial RAM disk. Example network hook scripts can be found in
66
"/usr/share/doc/mandos-client/examples/network-hooks.d".
49
68
* User-Supplied Plugins
51
70
Any plugins found in "/etc/mandos/plugins.d" will override and add
62
81
Mandos client will be the new default way for getting a password for
63
82
the root file system when booting.
67
If it ever should be necessary, the Mandos client can be temporarily
68
prevented from running at startup by passing the parameter
69
"mandos=off" to the kernel.
71
84
* Non-local Connection (Not Using ZeroConf)
73
86
If the "ip=" kernel command line option is used to specify a
74
87
complete IP address and device name, as noted above, it then becomes
75
88
possible to specify a specific IP address and port to connect to,
76
89
instead of using ZeroConf. The syntax for doing this is
77
"mandos=connect:<IP_ADDRESS>:<PORT_NUMBER>".
90
"mandos=connect:<IP_ADDRESS>:<PORT_NUMBER>" on the kernel command
79
93
For very advanced users, it it possible to specify simply
80
94
"mandos=connect" on the kernel command line to make the system only
83
97
work, "--options-for=mandos-client:--connect=<ADDRESS>:<PORT>" needs
84
98
to be manually added to the file "/etc/mandos/plugin-runner.conf".

* Diffie-Hellman Parameters
102
On installation, a file with Diffie-Hellman parameters,
103
/etc/keys/mandos/dhparams.pem, will be generated and automatically
104
installed into the initital RAM disk image and also used by the
105
Mandos Client on boot. If different parameters are needed for
106
policy or other reasons, simply replace the existing dhparams.pem
107
file and update the initital RAM disk image.
