111 <title>DESCRIPTION</title>
112 <para><command>named-checkzone</command>
113 checks the syntax and integrity of a zone file. It performs the
114 same checks as <command>named</command> does when loading a
115 zone. This makes <command>named-checkzone</command> useful for
116 checking zone files before configuring them into a name server.
119 <command>named-compilezone</command> is similar to
120 <command>named-checkzone</command>, but it always dumps the
121 zone contents to a specified file in a specified format.
122 Additionally, it applies stricter check levels by default,
123 since the dump output will be used as an actual zone file
124 loaded by <command>named</command>.
125 When manually specified otherwise, the check levels must at
126 least be as strict as those specified in the
127 <command>named</command> configuration file.
132 <title>OPTIONS</title>
148 Print the usage summary and exit.
157 Quiet mode - exit code only.
166 Print the version of the <command>named-checkzone</command>
176 When loading the zone file read the journal if it exists.
182 <term>-c <replaceable class="parameter">class</replaceable></term>
185 Specify the class of the zone. If not specified, "IN" is assumed.
191 <term>-i <replaceable class="parameter">mode</replaceable></term>
194 Perform post-load zone integrity checks. Possible modes are
195 <command>"full"</command> (default),
196 <command>"full-sibling"</command>,
197 <command>"local"</command>,
198 <command>"local-sibling"</command> and
199 <command>"none"</command>.
202 Mode <command>"full"</command> checks that MX records
203 refer to A or AAAA record (both in-zone and out-of-zone
204 hostnames). Mode <command>"local"</command> only
205 checks MX records which refer to in-zone hostnames.
208 Mode <command>"full"</command> checks that SRV records
209 refer to A or AAAA record (both in-zone and out-of-zone
210 hostnames). Mode <command>"local"</command> only
211 checks SRV records which refer to in-zone hostnames.
214 Mode <command>"full"</command> checks that delegation NS
215 records refer to A or AAAA record (both in-zone and out-of-zone
216 hostnames). It also checks that glue address records
217 in the zone match those advertised by the child.
218 Mode <command>"local"</command> only checks NS records which
219 refer to in-zone hostnames or that some required glue exists,
220 that is when the nameserver is in a child zone.
223 Mode <command>"full-sibling"</command> and
224 <command>"local-sibling"</command> disable sibling glue
225 checks but are otherwise the same as <command>"full"</command>
226 and <command>"local"</command> respectively.
229 Mode <command>"none"</command> disables the checks.
235 <term>-f <replaceable class="parameter">format</replaceable></term>
238 Specify the format of the zone file.
239 Possible formats are <command>"text"</command> (default)
240 and <command>"raw"</command>.
246 <term>-F <replaceable class="parameter">format</replaceable></term>
249 Specify the format of the output file specified.
250 Possible formats are <command>"text"</command> (default)
251 and <command>"raw"</command>.
252 For <command>named-checkzone</command>,
253 this does not cause any effects unless it dumps the zone
260 <term>-k <replaceable class="parameter">mode</replaceable></term>
263 Perform <command>"check-names"</command> checks with the
264 specified failure mode.
265 Possible modes are <command>"fail"</command>
266 (default for <command>named-compilezone</command>),
267 <command>"warn"</command>
268 (default for <command>named-checkzone</command>) and
269 <command>"ignore"</command>.
275 <term>-m <replaceable class="parameter">mode</replaceable></term>
278 Specify whether MX records should be checked to see if they
279 are addresses. Possible modes are <command>"fail"</command>,
280 <command>"warn"</command> (default) and
281 <command>"ignore"</command>.
287 <term>-M <replaceable class="parameter">mode</replaceable></term>
290 Check if a MX record refers to a CNAME.
291 Possible modes are <command>"fail"</command>,
292 <command>"warn"</command> (default) and
293 <command>"ignore"</command>.
299 <term>-n <replaceable class="parameter">mode</replaceable></term>
302 Specify whether NS records should be checked to see if they
304 Possible modes are <command>"fail"</command>
305 (default for <command>named-compilezone</command>),
306 <command>"warn"</command>
307 (default for <command>named-checkzone</command>) and
308 <command>"ignore"</command>.
314 <term>-o <replaceable class="parameter">filename</replaceable></term>
317 Write zone output to <filename>filename</filename>.
318 If <filename>filename</filename> is <filename>-</filename> then
319 write to standard out.
320 This is mandatory for <command>named-compilezone</command>.
326 <term>-r <replaceable class="parameter">mode</replaceable></term>
329 Check for records that are treated as different by DNSSEC but
330 are semantically equal in plain DNS.
331 Possible modes are <command>"fail"</command>,
332 <command>"warn"</command> (default) and
333 <command>"ignore"</command>.
339 <term>-s <replaceable class="parameter">style</replaceable></term>
342 Specify the style of the dumped zone file.
343 Possible styles are <command>"full"</command> (default)
344 and <command>"relative"</command>.
345 The full format is most suitable for processing
346 automatically by a separate script.
347 On the other hand, the relative format is more
348 human-readable and is thus suitable for editing by hand.
349 For <command>named-checkzone</command>
350 this does not cause any effects unless it dumps the zone
352 It also does not have any meaning if the output format
359 <term>-S <replaceable class="parameter">mode</replaceable></term>
362 Check if a SRV record refers to a CNAME.
363 Possible modes are <command>"fail"</command>,
364 <command>"warn"</command> (default) and
365 <command>"ignore"</command>.
371 <term>-t <replaceable class="parameter">directory</replaceable></term>
374 Chroot to <filename>directory</filename> so that
376 directives in the configuration file are processed as if
377 run by a similarly chrooted named.
383 <term>-w <replaceable class="parameter">directory</replaceable></term>
386 chdir to <filename>directory</filename> so that
388 filenames in master file $INCLUDE directives work. This
389 is similar to the directory clause in
390 <filename>named.conf</filename>.
399 Dump zone file in canonical format.
400 This is always enabled for <command>named-compilezone</command>.
406 <term>-W <replaceable class="parameter">mode</replaceable></term>
409 Specify whether to check for non-terminal wildcards.
410 Non-terminal wildcards are almost always the result of a
411 failure to understand the wildcard matching algorithm (RFC 1034).
412 Possible modes are <command>"warn"</command> (default)
414 <command>"ignore"</command>.
420 <term>zonename</term>
423 The domain name of the zone being checked.
429 <term>filename</term>
432 The name of the zone file.
442 <title>RETURN VALUES</title>
443 <para><command>named-checkzone</command>
444 returns an exit status of 1 if
445 errors were detected and 0 otherwise.
