to get a password. It uses IPv6 link-local addresses to get

network connectivity, Zeroconf to find servers, and TLS with an

to get a password. In slightly more detail, this client program
130
brings up a network interface, uses the interface’s IPv6
131
link-local address to get network connectivity, uses Zeroconf to
132
find servers on the local network, and communicates with servers
133
using TLS with an OpenPGP key to ensure authenticity and
134
confidentiality. This client program keeps running, trying all
135
servers on the network, until it receives a satisfactory reply
136
or a TERM signal is received. If no servers are found, or after
137
all servers have been tried, it waits indefinitely for new

This program is not meant to be run directly; it is really meant
199
210
specifies the interface to use to connect to the address
214
Note that since this program will normally run in the
215
initial RAM disk environment, the interface must be an
216
interface which exists at that stage. Thus, the interface
217
can not be a pseudo-interface such as <quote>br0</quote>
218
or <quote>tun0</quote>; such interfaces will not exist
219
until much later in the boot process, and can not be used

>SECONDS</replaceable></option></term>
278
After bringing the network interface up, the program waits
279
for the interface to arrive in a <quote>running</quote>
280
state before proceeding. During this time, the kernel log
281
level will be lowered to reduce clutter on the system
282
console, alleviating any other plugins which might be
283
using the system console. This option sets the upper
284
limit of seconds to wait. The default is 2.5 seconds.

The only remaining weak point is that someone with physical
450
486
access to the client hard drive might turn off the client
451
487
computer, read the OpenPGP keys directly from the hard drive,
452
and communicate with the server. The defense against this is
453
that the server is supposed to notice the client disappearing
454
and will stop giving out the encrypted data. Therefore, it is
455
important to set the timeout and checker interval values tightly
456
on the server. See <citerefentry><refentrytitle
