<command>&COMMANDNAME;</command> is a client program that
132
122
communicates with <citerefentry><refentrytitle

>mandos</refentrytitle><manvolnum>8</manvolnum></citerefentry>
134
to get a password. In slightly more detail, this client program
135
brings up a network interface, uses the interface’s IPv6
136
link-local address to get network connectivity, uses Zeroconf to
137
find servers on the local network, and communicates with servers
138
using TLS with an OpenPGP key to ensure authenticity and
139
confidentiality. This client program keeps running, trying all
140
servers on the network, until it receives a satisfactory reply
141
or a TERM signal. After all servers have been tried, all
142
servers are periodically retried. If no servers are found it
143
will wait indefinitely for new servers to appear.

Network interface that will be brought up and scanned for
210
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
216
200
specifies the interface to use to connect to the address
220
Note that since this program will normally run in the
221
initial RAM disk environment, the interface must be an
222
interface which exists at that stage. Thus, the interface
223
can not be a pseudo-interface such as <quote>br0</quote>
224
or <quote>tun0</quote>; such interfaces will not exist
225
until much later in the boot process, and can not be used
229
<replaceable>NAME</replaceable> can be the string
230
<quote><literal>none</literal></quote>; this will not use
231
any specific interface, and will not bring up an interface
232
on startup. This is not recommended, and only meant for

291
After bringing the network interface up, the program waits
292
for the interface to arrive in a <quote>running</quote>
293
state before proceeding. During this time, the kernel log
294
level will be lowered to reduce clutter on the system
295
console, alleviating any other plugins which might be
296
using the system console. This option sets the upper
297
limit of seconds to wait. The default is 2.5 seconds.

All Mandos servers are tried repeatedly until a password
308
is received. This value specifies, in seconds, how long
309
between each successive try <emphasis>for the same

330
program will exit with a non-zero exit status only if a critical
392
error occurs. Otherwise, it will forever connect to any

get a decryptable password and print it.
