to get a password. In slightly more detail, this client program
140
brings up a network interface, uses the interface’s IPv6

find servers on the local network, and communicates with servers

servers using TLS with an OpenPGP key to ensure authenticity and

148
confidentiality. This client program keeps running, trying all
145
149
servers on the network, until it receives a satisfactory reply
146
150
or a TERM signal. After all servers have been tried, all
148
152
will wait indefinitely for new servers to appear.

The network interface is selected like this: If an interface is
152
specified using the <option>--interface</option> option, that
153
interface is used. Otherwise, <command>&COMMANDNAME;</command>
154
will choose any interface that is up and running and is not a
155
loopback interface, is not a point-to-point interface, is
156
capable of broadcasting and does not have the NOARP flag (see

159
163
<option>--connect</option> option is used, point-to-point
160
interfaces and non-broadcast interfaces are accepted.) If no
161
acceptable interfaces are found, re-run the check but without
162
the <quote>up and running</quote> requirement, and manually take
163
the selected interface up (and later take it down on program

until much later in the boot process, and can not be used

This should make the network hook print, <emphasis>on
