Configuration file for Mandos clients

Configuration file for the Mandos server

</refpurpose>

</refnamediv>

<title>DESCRIPTION</title>

<para>

The file &CONFPATH; is the configuration file for mandos where

each client that will be abel to use the service need to be

specified. The configuration file is looked on at the startup of

the service, so to reenable timedout clients one need to only

restart the server. The format starts with a section under []

which is eather <literal>[DEFAULT]</literal> or a client

name. Values is set through the use of VAR = VALUE pair. Values

may not be empty.

The file &CONFPATH; is the configuration file for <citerefentry

><refentrytitle>mandos</refentrytitle>

<manvolnum>8</manvolnum></citerefentry>, read by it at startup,

where each client that will be able to use the service needs to

be listed. All clients listed will be regarded as valid, even

if a client was declared invalid in a previous run of the

server.

</para>

<para>

The format starts with a <literal>[<replaceable>section

header</replaceable>]</literal> which is either

<literal>[DEFAULT]</literal> or <literal>[<replaceable>client

name</replaceable>]</literal>. The <replaceable>client

name</replaceable> can be anything, and is not tied to a host

name. Following the section header is any number of

<quote><varname><replaceable>option</replaceable

></varname>=<replaceable>value</replaceable></quote> entries,

with continuations in the style of RFC 822. <quote><varname

100

><replaceable>option</replaceable></varname>: <replaceable

101

>value</replaceable></quote> is also accepted. Note that

102

leading whitespace is removed from values. Values can contain

103

format strings which refer to other values in the same section,

104

or values in the <quote>DEFAULT</quote> section (see <xref

105

linkend="expansion"/>). Lines beginning with <quote>#</quote>

106

or <quote>;</quote> are ignored and may be used to provide

107

comments.

<para>

106

This option allows you to override the default timeout

107

that clients will get. By default mandos will use 1hr.

122

<synopsis><literal>timeout = </literal><replaceable

123

>TIME</replaceable>

124

</synopsis>

125

<para>

126

The timeout is how long the server will wait for a

127

successful checker run until a client is considered

128

invalid - that is, ineligible to get the data this server

129

holds. By default Mandos will use 1 hour.

130

</para>

131

<para>

132

The <replaceable>TIME</replaceable> is specified as a

133

space-separated number of values, each of which is a

134

number and a one-character suffix. The suffix must be one

135

of <quote>d</quote>, <quote>s</quote>, <quote>m</quote>,

136

<quote>h</quote>, and <quote>w</quote> for days, seconds,

137

minutes, hours, and weeks, respectively. The values are

138

added together to give the total time value, so all of

139

<quote><literal>330s</literal></quote>,

140

<quote><literal>110s 110s 110s</literal></quote>, and

141

<quote><literal>5m 30s</literal></quote> will give a value

142

of five minutes and thirty seconds.

This option allows you to override the default interval

mandos will use 5m.

<para>

154

How often to run the checker to confirm that a client is

155

still up. <emphasis>Note:</emphasis> a new checker will

156

not be started if an old one is still running. The server

157

will wait for a checker to complete until the above

158

<quote><varname>timeout</varname></quote> occurs, at which

159

time the client will be marked invalid, and any running

160

checker killed. The default interval is 5 minutes.

161

</para>

162

<para>

163

The format of <replaceable>TIME</replaceable> is the same

164

<para>

127

176

This option allows you to override the default shell

128

command that the server will use to check up if the client

129

is still up. By default mandos will "fping -q -- %%(host)s"

177

command that the server will use to check if the client is

178

still up. The output of the command will be ignored, only

179

the exit code is checked. The command will be run using

180

181

<option>-c</option></command></quote>. The default

182

command is <quote><literal><command>fping</command>

183

184

%(host)s</literal></quote>.

</para>

In addition to normal start time expansion, this option

This option sets the openpgp fingerprint that identifies

150

the public certificate that clients authenticates themself

151

through gnutls. The string need to be in hex-decimal form.

201

This option sets the OpenPGP fingerprint that identifies

202

the public key that clients authenticate themselves with

203

through TLS. The string needs to be in hexidecimal form,

204

but spaces or upper/lower case are not significant.

216

If present, this option must be set to a string of

217

base64-encoded binary data. It will be decoded and sent

218

to the client matching the above

219

<option>fingerprint</option>. This should, of course, be

220

OpenPGP encrypted data, decryptable only by the client.

<para>

227

Note: this value of this option will probably run over

228

many lines, and will then have to use the fact that a line

beginning with white space adds to the value of the

230

previous line, RFC 822-style.

<title>EXPANSION</title>

There are two forms of expansion: Start time expansion and

281

runtime expansion.

<title>START TIME EXPANSION</title>

285

<para>

286

Any string in an option value of the form

287

<quote><literal>%(<replaceable>foo</replaceable>)s</literal

288

></quote> will be replaced by the value of the option

289

<varname>foo</varname> either in the same section, or, if it

290

does not exist there, the <literal>[DEFAULT]</literal>

291

section. This is done at start time, when the configuration

292

file is read.

293

</para>

294

<para>

295

Note that this means that, in order to include an actual

296

percent character (<quote>%</quote>) in an option value, two

297

percent characters in a row (<quote>%%</quote>) must be

298

entered.

305

option.

</para>

307

<para>

308

Any string in an option value of the form

309

<quote><literal>%%(<replaceable>foo</replaceable>)s</literal

310

></quote> will be replaced by the value of the attribute

311

<varname>foo</varname> of the internal

312

<quote><classname>Client</classname></quote> object. See the

313

source code for details, and let the authors know of any

314

attributes that are useful so they may be preserved to any new

315

versions of this software.

316

</para>

317

<para>

318

Note that this means that, in order to include an actual

319

percent character (<quote>%</quote>) in a

320

<varname>checker</varname> options, <emphasis>four</emphasis>

321

percent characters in a row (<quote>%%%%</quote>) must be

322

entered. Also, a bad format here will lead to an immediate

323

but <emphasis>silent</emphasis> run-time fatal exit; debug

324

mode is needed to track down an error of this kind.
