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".

any extra "--connect" options to mandos-client at boot. For this to

* Diffie-Hellman Parameters
104
On installation, a file with Diffie-Hellman parameters,
105
/etc/keys/mandos/dhparams.pem, will be generated and automatically
106
installed into the initital RAM disk image and also used by the
107
Mandos Client on boot. If different parameters are needed for
108
policy or other reasons, simply replace the existing dhparams.pem
109
file and update the initital RAM disk image.
