<command>&COMMANDNAME;</command> is a client program that
123
132
communicates with <citerefentry><refentrytitle

>mandos</refentrytitle><manvolnum>8</manvolnum></citerefentry>
125
to get a password. It brings up a network interface, uses its
126
IPv6 link-local address to get network connectivity, uses
127
Zeroconf to find servers, and uses TLS with an OpenPGP key to
128
ensure authenticity and confidentiality. It keeps running,
129
trying all servers on the network, until it receives a
130
satisfactory reply or a TERM signal is received.
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.

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

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

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

program will exit with a non-zero exit status only if a critical
