54 <a name="id2601603"></a><h2>DESCRIPTION</h2>
55 <p><span><strong class="command">named-checkzone</strong></span>
56 checks the syntax and integrity of a zone file. It performs the
57 same checks as <span><strong class="command">named</strong></span> does when loading a
58 zone. This makes <span><strong class="command">named-checkzone</strong></span> useful for
59 checking zone files before configuring them into a name server.
62 <span><strong class="command">named-compilezone</strong></span> is similar to
63 <span><strong class="command">named-checkzone</strong></span>, but it always dumps the
64 zone contents to a specified file in a specified format.
65 Additionally, it applies stricter check levels by default,
66 since the dump output will be used as an actual zone file
67 loaded by <span><strong class="command">named</strong></span>.
68 When manually specified otherwise, the check levels must at
69 least be as strict as those specified in the
70 <span><strong class="command">named</strong></span> configuration file.

75 <div class="variablelist"><dl>
76 <dt><span class="term">-d</span></dt>
80 <dt><span class="term">-q</span></dt>
82 Quiet mode - exit code only.
84 <dt><span class="term">-v</span></dt>
86 Print the version of the <span><strong class="command">named-checkzone</strong></span>
89 <dt><span class="term">-j</span></dt>
91 When loading the zone file read the journal if it exists.
93 <dt><span class="term">-c <em class="replaceable"><code>class</code></em></span></dt>
95 Specify the class of the zone. If not specified "IN" is assumed.
97 <dt><span class="term">-i <em class="replaceable"><code>mode</code></em></span></dt>
100 Perform post-load zone integrity checks. Possible modes are
101 <span><strong class="command">"full"</strong></span> (default),
102 <span><strong class="command">"full-sibling"</strong></span>,
103 <span><strong class="command">"local"</strong></span>,
104 <span><strong class="command">"local-sibling"</strong></span> and
105 <span><strong class="command">"none"</strong></span>.
108 Mode <span><strong class="command">"full"</strong></span> checks that MX records
109 refer to A or AAAA record (both in-zone and out-of-zone
110 hostnames). Mode <span><strong class="command">"local"</strong></span> only
111 checks MX records which refer to in-zone hostnames.
114 Mode <span><strong class="command">"full"</strong></span> checks that SRV records
115 refer to A or AAAA record (both in-zone and out-of-zone
116 hostnames). Mode <span><strong class="command">"local"</strong></span> only
117 checks SRV records which refer to in-zone hostnames.
120 Mode <span><strong class="command">"full"</strong></span> checks that delegation NS
121 records refer to A or AAAA record (both in-zone and out-of-zone
122 hostnames). It also checks that glue address records
123 in the zone match those advertised by the child.
124 Mode <span><strong class="command">"local"</strong></span> only checks NS records which
125 refer to in-zone hostnames or that some required glue exists,
126 that is when the nameserver is in a child zone.
129 Mode <span><strong class="command">"full-sibling"</strong></span> and
130 <span><strong class="command">"local-sibling"</strong></span> disable sibling glue
131 checks but are otherwise the same as <span><strong class="command">"full"</strong></span>
132 and <span><strong class="command">"local"</strong></span> respectively.
135 Mode <span><strong class="command">"none"</strong></span> disables the checks.
138 <dt><span class="term">-f <em class="replaceable"><code>format</code></em></span></dt>
140 Specify the format of the zone file.
141 Possible formats are <span><strong class="command">"text"</strong></span> (default)
142 and <span><strong class="command">"raw"</strong></span>.
144 <dt><span class="term">-F <em class="replaceable"><code>format</code></em></span></dt>
146 Specify the format of the output file specified.
147 Possible formats are <span><strong class="command">"text"</strong></span> (default)
148 and <span><strong class="command">"raw"</strong></span>.
149 For <span><strong class="command">named-checkzone</strong></span>,
150 this does not cause any effects unless it dumps the zone
153 <dt><span class="term">-k <em class="replaceable"><code>mode</code></em></span></dt>
155 Perform <span><strong class="command">"check-names"</strong></span> checks with the
156 specified failure mode.
157 Possible modes are <span><strong class="command">"fail"</strong></span>
158 (default for <span><strong class="command">named-compilezone</strong></span>),
159 <span><strong class="command">"warn"</strong></span>
160 (default for <span><strong class="command">named-checkzone</strong></span>) and
161 <span><strong class="command">"ignore"</strong></span>.
163 <dt><span class="term">-m <em class="replaceable"><code>mode</code></em></span></dt>
165 Specify whether MX records should be checked to see if they
166 are addresses. Possible modes are <span><strong class="command">"fail"</strong></span>,
167 <span><strong class="command">"warn"</strong></span> (default) and
168 <span><strong class="command">"ignore"</strong></span>.
170 <dt><span class="term">-M <em class="replaceable"><code>mode</code></em></span></dt>
172 Check if a MX record refers to a CNAME.
173 Possible modes are <span><strong class="command">"fail"</strong></span>,
174 <span><strong class="command">"warn"</strong></span> (default) and
175 <span><strong class="command">"ignore"</strong></span>.
177 <dt><span class="term">-n <em class="replaceable"><code>mode</code></em></span></dt>
179 Specify whether NS records should be checked to see if they
181 Possible modes are <span><strong class="command">"fail"</strong></span>
182 (default for <span><strong class="command">named-compilezone</strong></span>),
183 <span><strong class="command">"warn"</strong></span>
184 (default for <span><strong class="command">named-checkzone</strong></span>) and
185 <span><strong class="command">"ignore"</strong></span>.
187 <dt><span class="term">-o <em class="replaceable"><code>filename</code></em></span></dt>
189 Write zone output to <code class="filename">filename</code>.
190 This is mandatory for <span><strong class="command">named-compilezone</strong></span>.
192 <dt><span class="term">-s <em class="replaceable"><code>style</code></em></span></dt>
194 Specify the style of the dumped zone file.
195 Possible styles are <span><strong class="command">"full"</strong></span> (default)
196 and <span><strong class="command">"relative"</strong></span>.
197 The full format is most suitable for processing
198 automatically by a separate script.
199 On the other hand, the relative format is more
200 human-readable and is thus suitable for editing by hand.
201 For <span><strong class="command">named-checkzone</strong></span>
202 this does not cause any effects unless it dumps the zone
204 It also does not have any meaning if the output format
207 <dt><span class="term">-S <em class="replaceable"><code>mode</code></em></span></dt>
209 Check if a SRV record refers to a CNAME.
210 Possible modes are <span><strong class="command">"fail"</strong></span>,
211 <span><strong class="command">"warn"</strong></span> (default) and
212 <span><strong class="command">"ignore"</strong></span>.
214 <dt><span class="term">-t <em class="replaceable"><code>directory</code></em></span></dt>
216 Chroot to <code class="filename">directory</code> so that
218 directives in the configuration file are processed as if
219 run by a similarly chrooted named.
221 <dt><span class="term">-w <em class="replaceable"><code>directory</code></em></span></dt>
223 chdir to <code class="filename">directory</code> so that
225 filenames in master file $INCLUDE directives work. This
226 is similar to the directory clause in
227 <code class="filename">named.conf</code>.
229 <dt><span class="term">-D</span></dt>
231 Dump zone file in canonical format.
232 This is always enabled for <span><strong class="command">named-compilezone</strong></span>.
234 <dt><span class="term">-W <em class="replaceable"><code>mode</code></em></span></dt>
236 Specify whether to check for non-terminal wildcards.
237 Non-terminal wildcards are almost always the result of a
238 failure to understand the wildcard matching algorithm (RFC 1034).
239 Possible modes are <span><strong class="command">"warn"</strong></span> (default)
241 <span><strong class="command">"ignore"</strong></span>.
243 <dt><span class="term">zonename</span></dt>
245 The domain name of the zone being checked.
247 <dt><span class="term">filename</span></dt>
249 The name of the zone file.
