36 <a name="id2543736"></a><h2>DESCRIPTION</h2>
37 <p><span><strong class="command">named-checkzone</strong></span>
38 checks the syntax and integrity of a zone file. It performs the
39 same checks as <span><strong class="command">named</strong></span> does when loading a
40 zone. This makes <span><strong class="command">named-checkzone</strong></span> useful for
41 checking zone files before configuring them into a name server.
44 <span><strong class="command">named-compilezone</strong></span> is similar to
45 <span><strong class="command">named-checkzone</strong></span>, but it always dumps the
46 zone contents to a specified file in a specified format.
47 Additionally, it applies stricter check levels by default,
48 since the dump output will be used as an actual zone file
49 loaded by <span><strong class="command">named</strong></span>.
50 When manually specified otherwise, the check levels must at
51 least be as strict as those specified in the
52 <span><strong class="command">named</strong></span> configuration file.

57 <div class="variablelist"><dl>
58 <dt><span class="term">-d</span></dt>
62 <dt><span class="term">-h</span></dt>
64 Print the usage summary and exit.
66 <dt><span class="term">-q</span></dt>
68 Quiet mode - exit code only.
70 <dt><span class="term">-v</span></dt>
72 Print the version of the <span><strong class="command">named-checkzone</strong></span>
75 <dt><span class="term">-j</span></dt>
77 When loading the zone file read the journal if it exists.
79 <dt><span class="term">-c <em class="replaceable"><code>class</code></em></span></dt>
81 Specify the class of the zone. If not specified, "IN" is assumed.
83 <dt><span class="term">-i <em class="replaceable"><code>mode</code></em></span></dt>
86 Perform post-load zone integrity checks. Possible modes are
87 <span><strong class="command">"full"</strong></span> (default),
88 <span><strong class="command">"full-sibling"</strong></span>,
89 <span><strong class="command">"local"</strong></span>,
90 <span><strong class="command">"local-sibling"</strong></span> and
91 <span><strong class="command">"none"</strong></span>.
94 Mode <span><strong class="command">"full"</strong></span> checks that MX records
95 refer to A or AAAA record (both in-zone and out-of-zone
96 hostnames). Mode <span><strong class="command">"local"</strong></span> only
97 checks MX records which refer to in-zone hostnames.
100 Mode <span><strong class="command">"full"</strong></span> checks that SRV records
101 refer to A or AAAA record (both in-zone and out-of-zone
102 hostnames). Mode <span><strong class="command">"local"</strong></span> only
103 checks SRV records which refer to in-zone hostnames.
106 Mode <span><strong class="command">"full"</strong></span> checks that delegation NS
107 records refer to A or AAAA record (both in-zone and out-of-zone
108 hostnames). It also checks that glue address records
109 in the zone match those advertised by the child.
110 Mode <span><strong class="command">"local"</strong></span> only checks NS records which
111 refer to in-zone hostnames or that some required glue exists,
112 that is when the nameserver is in a child zone.
115 Mode <span><strong class="command">"full-sibling"</strong></span> and
116 <span><strong class="command">"local-sibling"</strong></span> disable sibling glue
117 checks but are otherwise the same as <span><strong class="command">"full"</strong></span>
118 and <span><strong class="command">"local"</strong></span> respectively.
121 Mode <span><strong class="command">"none"</strong></span> disables the checks.
124 <dt><span class="term">-f <em class="replaceable"><code>format</code></em></span></dt>
126 Specify the format of the zone file.
127 Possible formats are <span><strong class="command">"text"</strong></span> (default)
128 and <span><strong class="command">"raw"</strong></span>.
130 <dt><span class="term">-F <em class="replaceable"><code>format</code></em></span></dt>
133 Specify the format of the output file specified.
134 For <span><strong class="command">named-checkzone</strong></span>,
135 this does not cause any effects unless it dumps the zone
139 Possible formats are <span><strong class="command">"text"</strong></span> (default)
140 and <span><strong class="command">"raw"</strong></span> or <span><strong class="command">"raw=N"</strong></span>,
141 which store the zone in a binary format for rapid loading
142 by <span><strong class="command">named</strong></span>. <span><strong class="command">"raw=N"</strong></span>
143 specifies the format version of the raw zone file: if N
144 is 0, the raw file can be read by any version of
145 <span><strong class="command">named</strong></span>; if N is 1, the file can be read
146 by release 9.9.0 or higher. The default is 1.
149 <dt><span class="term">-k <em class="replaceable"><code>mode</code></em></span></dt>
151 Perform <span><strong class="command">"check-names"</strong></span> checks with the
152 specified failure mode.
153 Possible modes are <span><strong class="command">"fail"</strong></span>
154 (default for <span><strong class="command">named-compilezone</strong></span>),
155 <span><strong class="command">"warn"</strong></span>
156 (default for <span><strong class="command">named-checkzone</strong></span>) and
157 <span><strong class="command">"ignore"</strong></span>.
159 <dt><span class="term">-L <em class="replaceable"><code>serial</code></em></span></dt>
161 When compiling a zone to 'raw' format, set the "source serial"
162 value in the header to the specified serial number. (This is
163 expected to be used primarily for testing purposes.)
165 <dt><span class="term">-m <em class="replaceable"><code>mode</code></em></span></dt>
167 Specify whether MX records should be checked to see if they
168 are addresses. Possible modes are <span><strong class="command">"fail"</strong></span>,
169 <span><strong class="command">"warn"</strong></span> (default) and
170 <span><strong class="command">"ignore"</strong></span>.
172 <dt><span class="term">-M <em class="replaceable"><code>mode</code></em></span></dt>
174 Check if a MX record refers to a CNAME.
175 Possible modes are <span><strong class="command">"fail"</strong></span>,
176 <span><strong class="command">"warn"</strong></span> (default) and
177 <span><strong class="command">"ignore"</strong></span>.
179 <dt><span class="term">-n <em class="replaceable"><code>mode</code></em></span></dt>
181 Specify whether NS records should be checked to see if they
183 Possible modes are <span><strong class="command">"fail"</strong></span>
184 (default for <span><strong class="command">named-compilezone</strong></span>),
185 <span><strong class="command">"warn"</strong></span>
186 (default for <span><strong class="command">named-checkzone</strong></span>) and
187 <span><strong class="command">"ignore"</strong></span>.
189 <dt><span class="term">-o <em class="replaceable"><code>filename</code></em></span></dt>
191 Write zone output to <code class="filename">filename</code>.
192 If <code class="filename">filename</code> is <code class="filename">-</code> then
193 write to standard out.
194 This is mandatory for <span><strong class="command">named-compilezone</strong></span>.
196 <dt><span class="term">-r <em class="replaceable"><code>mode</code></em></span></dt>
198 Check for records that are treated as different by DNSSEC but
199 are semantically equal in plain DNS.
200 Possible modes are <span><strong class="command">"fail"</strong></span>,
201 <span><strong class="command">"warn"</strong></span> (default) and
202 <span><strong class="command">"ignore"</strong></span>.
204 <dt><span class="term">-s <em class="replaceable"><code>style</code></em></span></dt>
206 Specify the style of the dumped zone file.
207 Possible styles are <span><strong class="command">"full"</strong></span> (default)
208 and <span><strong class="command">"relative"</strong></span>.
209 The full format is most suitable for processing
210 automatically by a separate script.
211 On the other hand, the relative format is more
212 human-readable and is thus suitable for editing by hand.
213 For <span><strong class="command">named-checkzone</strong></span>
214 this does not cause any effects unless it dumps the zone
216 It also does not have any meaning if the output format
219 <dt><span class="term">-S <em class="replaceable"><code>mode</code></em></span></dt>
221 Check if a SRV record refers to a CNAME.
222 Possible modes are <span><strong class="command">"fail"</strong></span>,
223 <span><strong class="command">"warn"</strong></span> (default) and
224 <span><strong class="command">"ignore"</strong></span>.
226 <dt><span class="term">-t <em class="replaceable"><code>directory</code></em></span></dt>
228 Chroot to <code class="filename">directory</code> so that
230 directives in the configuration file are processed as if
231 run by a similarly chrooted named.
233 <dt><span class="term">-T <em class="replaceable"><code>mode</code></em></span></dt>
235 Check if Sender Policy Framework records (TXT and SPF)
236 both exist or both don't exist. A warning is issued
237 if they don't match. Possible modes are
238 <span><strong class="command">"warn"</strong></span> (default), <span><strong class="command">"ignore"</strong></span>.
240 <dt><span class="term">-w <em class="replaceable"><code>directory</code></em></span></dt>
242 chdir to <code class="filename">directory</code> so that
244 filenames in master file $INCLUDE directives work. This
245 is similar to the directory clause in
246 <code class="filename">named.conf</code>.
248 <dt><span class="term">-D</span></dt>
250 Dump zone file in canonical format.
251 This is always enabled for <span><strong class="command">named-compilezone</strong></span>.
253 <dt><span class="term">-W <em class="replaceable"><code>mode</code></em></span></dt>
255 Specify whether to check for non-terminal wildcards.
256 Non-terminal wildcards are almost always the result of a
257 failure to understand the wildcard matching algorithm (RFC 1034).
258 Possible modes are <span><strong class="command">"warn"</strong></span> (default)
260 <span><strong class="command">"ignore"</strong></span>.
262 <dt><span class="term">zonename</span></dt>
264 The domain name of the zone being checked.
266 <dt><span class="term">filename</span></dt>
268 The name of the zone file.
