<command>&COMMANDNAME;</command> is a client program that
136
122
communicates with <citerefentry><refentrytitle

123
>mandos</refentrytitle><manvolnum>8</manvolnum></citerefentry>
138
to get a password. In slightly more detail, this client program
139
brings up a network interface, uses the interface’s IPv6
140
link-local address to get network connectivity, uses Zeroconf to
141
find servers on the local network, and communicates with servers
142
using TLS with an OpenPGP key to ensure authenticity and
143
confidentiality. This client program keeps running, trying all
144
servers on the network, until it receives a satisfactory reply
145
or a TERM signal. After all servers have been tried, all
146
servers are periodically retried. If no servers are found it
147
will wait indefinitely for new servers to appear.

194
Network interface that will be brought up and scanned for
214
Mandos servers to connect to. The default is the empty

string, which will automatically choose an appropriate

If the <option>--connect</option> option is used, this

200
specifies the interface to use to connect to the address
224
Note that since this program will normally run in the
225
initial RAM disk environment, the interface must be an
226
interface which exists at that stage. Thus, the interface
227
can not be a pseudo-interface such as <quote>br0</quote>
228
or <quote>tun0</quote>; such interfaces will not exist
229
until much later in the boot process, and can not be used
233
<replaceable>NAME</replaceable> can be the string
234
<quote><literal>none</literal></quote>; this will not use
235
any specific interface, and will not bring up an interface

on startup. This is not recommended, and only meant for

295
After bringing the network interface up, the program waits
296
for the interface to arrive in a <quote>running</quote>
297
state before proceeding. During this time, the kernel log
298
level will be lowered to reduce clutter on the system
299
console, alleviating any other plugins which might be
300
using the system console. This option sets the upper
301
limit of seconds to wait. The default is 2.5 seconds.

All Mandos servers are tried repeatedly until a password

is received. This value specifies, in seconds, how long
313
between each successive try <emphasis>for the same

407
330
program will exit with a non-zero exit status only if a critical
408
error occurs. Otherwise, it will forever connect to any
