<title>DESCRIPTION</title>

141

<para>

142

<command>&COMMANDNAME;</command> is a program which is meant to

143

be specified as <quote>keyscript</quote> in <citerefentry>

144

<refentrytitle>crypttab</refentrytitle>

145

<manvolnum>5</manvolnum></citerefentry> for the root disk. The

146

aim of this program is therefore to output a password, which

147

then <citerefentry><refentrytitle>cryptsetup</refentrytitle>

148

<manvolnum>8</manvolnum></citerefentry> will use to try and

149

unlock the root disk.

150

</para>

151

<para>

152

This program is not meant to be invoked directly, but can be in

153

order to test it. Note that any password obtained will simply

154

be output on standard output.

<title>OVERVIEW</title>

383

<xi:include href="overview.xml"/>

384

<para>

385

This program will run on the client side in the initial

386

<acronym>RAM</acronym> disk environment, and is responsible for

387

getting a password. It does this by running plugins, one of

388

which will normally be the actual client program communicating

389

with the server.

390

</para>

391

</refsect1>

392

393

<title>PLUGINS</title>

394

<para>

395

This program will get a password by running a number of

396

<firstterm>plugins</firstterm>, which are simply executable

397

programs in a directory in the initial <acronym>RAM</acronym>

398

disk environment. The default directory is

399

<filename>/lib/mandos/plugins.d</filename>, but this can be

400

changed with the <option>--plugin-dir</option> option. The

401

plugins are started in parallel, and the first plugin to output

402

a password <emphasis>and</emphasis> exit with a successful exit

403

code will make this plugin-runner output the password from that

404

plugin, stop any other plugins, and exit.

405

</para>

406

</refsect1>

407

408

409

<title>FALLBACK</title>

410

<para>

411

If no plugins succeed, this program will, as a fallback, ask for

412

a password on the console using <citerefentry><refentrytitle

413

>getpass</refentrytitle><manvolnum>3</manvolnum></citerefentry>,

414

and output it. This is not meant to be the normal mode of

415

operation, as there is a separate plugin for getting a password

416

from the console.

417

</para>

418

</refsect1>

419

420

421

<title>EXIT STATUS</title>

422

<para>

423

Exit status of this program is zero if no errors were

424

encountered, and otherwise not. The fallback (see <xref

425

linkend="fallback"/>) may or may not have succeeded in either

426

case.

427

</para>

428

</refsect1>

429

430

431

<title>ENVIRONMENT</title>

432

<para>

433

This program does not use any environment variables itself, it

434

only passes on its environment to all the plugins. The

435

environment passed to plugins can be modified using the

436

<option>--global-env</option> and <option>--env-for</option>

437

optins.

446

<term><filename

447

>/conf/conf.d/mandos/plugin-runner.conf</filename></term>

448

449

<para>

450

Since this program will be run as a keyscript, there is

451

little to no opportunity to pass command line arguments

452

to it. Therefore, it will <emphasis>also</emphasis>

453

read this file and use its contents as

454

whitespace-separated command line options. Also,

455

everything from a <quote>#</quote> character to the end

456

of a line is ignored.

457

</para>

458

<para>

459

This program is meant to run in the initial RAM disk

460

environment, so that is where this file is assumed to

461

exist. The file does not need to exist in the normal

462

file system.

463

</para>

464

<para>

465

This file will be processed <emphasis>before</emphasis>

466

the normal command line options, so the latter can

467

override the former, if need be.

468

</para>

469

<para>

470

This file name is the default; the file to read for

471

arguments can be changed using the
