* Specifying a Client Network Interface

At boot time the network interface to use will by default be
36
automatically detected. If this should result in an incorrect

interface, edit the DEVICE setting in the

51
Note that since this network interface is used in the initial RAM
52
disk environment, the network interface *must* exist at that stage.
53
Thus, the interface can *not* be a pseudo-interface such as "br0" or
54
"tun0"; instead, only real interface (such as "eth0") can be used.
55
This can be overcome by writing a "network hook" program to create
56
the 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".

For very advanced users, it it possible to specify simply
87
"mandos=connect" on the kernel command line to make the system only
88
set up the network (using the data in the "ip=" option) and not pass
89
any extra "--connect" options to mandos-client at boot. For this to
90
work, "--options-for=mandos-client:--connect=<ADDRESS>:<PORT>" needs
91
to be manually added to the file "/etc/mandos/plugin-runner.conf".

* Diffie-Hellman Parameters
116
On installation, a file with Diffie-Hellman parameters,
117
/etc/keys/mandos/dhparams.pem, will be generated and automatically
118
installed into the initial RAM disk image and also used by the
119
Mandos Client on boot. If different parameters are needed for
120
policy or other reasons, simply replace the existing dhparams.pem
121
file and update the initial RAM disk image.
