<title>DESCRIPTION</title>

105

<para>

106

All <command>&COMMANDNAME;</command> does is prompt for a

107

password and output any given password to standard output. This

108

is not very useful on its own. This program is really meant to

109

run as a plugin in the <application>Mandos</application>

110

client-side system, where it is used as a fallback and

111

alternative to retriving passwords from a <application

112

>Mandos</application> server.

113

</para>

114

<para>

115

This program is little more than a <citerefentry><refentrytitle

116

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

117

wrapper, although actual use of that function is not guaranteed

118

or implied.

<title>OPTIONS</title>

124

<para>

125

This program is commonly not invoked from the command line; it

126

is normally started by the <application>Mandos</application>

127

plugin runner, see <citerefentry><refentrytitle

128

>plugin-runner</refentrytitle><manvolnum>8mandos</manvolnum>

129

</citerefentry>. Any command line options this program accepts

130

are therefore normally provided by the plugin runner, and not

131

directly.

150

<para>

151

Enable debug mode. This will enable a lot of output to

152

standard error about what the program is doing. The

153

program will still perform all other functions normally.

<title>EXIT STATUS</title>

191

<para>

192

If exit status is 0, the output from the program is the password

193

as it was read. Otherwise, if exit status is other than 0, the

194

program has encountered an error, and any output so far could be

195

corrupt and/or truncated, and should therefore be ignored.

205

206

<para>

207

If set, these environment variables will be assumed to

208

contain the source device name and the target device

209

mapper name, respectively, and will be shown as part of

210

the prompt.

211

</para>

212

<para>

213

These variables will normally be inherited from

214

<citerefentry><refentrytitle>plugin-runner</refentrytitle>

215

<manvolnum>8mandos</manvolnum></citerefentry>, which will

216

normally have inherited them from

217

<filename>/scripts/local-top/cryptroot</filename> in the

218

initial RAM disk environment, which will have set them from

219

parsing kernel arguments and

220

<filename>/conf/conf.d/cryptroot</filename> (also in the

221

initial RAM disk environment), which in turn will have been

222

created when the initial RAM disk image was created by

223

<filename

224

>/usr/share/initramfs-tools/hooks/cryptroot</filename>, by

225

extracting the information of the root file system from

226

<filename >/etc/crypttab</filename>.

227

</para>

228

<para>

229

This behavior is meant to exactly mirror the behavior of

230

<command>askpass</command>, the default password prompter.

Note that normally, command line options will not be given

248

directly, but via options for the Mandos <citerefentry

249

250

<manvolnum>8mandos</manvolnum></citerefentry>.

<para>

Show a prefix before the prompt; in this case, a host name.

263

It might be useful to be reminded of which host needs a

<title>SECURITY</title>

286

<para>

287

On its own, this program is very simple, and does not exactly

288

present any security risks. The one thing that could be

289

considered worthy of note is this: This program is meant to be

290

run by <citerefentry><refentrytitle

291

>plugin-runner</refentrytitle><manvolnum>8mandos</manvolnum>

292

</citerefentry>, and will, when run standalone, outside, in a

293

normal environment, immediately output on its standard output

294

any presumably secret password it just recieved. Therefore,

295

when running this program standalone (which should never

296

normally be done), take care not to type in any real secret

297

password by force of habit, since it would then immediately be

298

shown as output.

299

</para>

300

<para>

301

To further alleviate any risk of being locked out of a system,

302

the <citerefentry><refentrytitle>plugin-runner</refentrytitle>

303

<manvolnum>8mandos</manvolnum></citerefentry> has a fallback

304

mode which does the same thing as this program, only with less

305

features.
