54 <a name="id2609973"></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">-h</span></dt>
82 Print the usage summary and exit.
84 <dt><span class="term">-q</span></dt>
86 Quiet mode - exit code only.
88 <dt><span class="term">-v</span></dt>
90 Print the version of the <span><strong class="command">named-checkzone</strong></span>
93 <dt><span class="term">-j</span></dt>
95 When loading the zone file read the journal if it exists.
97 <dt><span class="term">-c <em class="replaceable"><code>class</code></em></span></dt>
99 Specify the class of the zone. If not specified, "IN" is assumed.
101 <dt><span class="term">-i <em class="replaceable"><code>mode</code></em></span></dt>
104 Perform post-load zone integrity checks. Possible modes are
105 <span><strong class="command">"full"</strong></span> (default),
106 <span><strong class="command">"full-sibling"</strong></span>,
107 <span><strong class="command">"local"</strong></span>,
108 <span><strong class="command">"local-sibling"</strong></span> and
109 <span><strong class="command">"none"</strong></span>.
112 Mode <span><strong class="command">"full"</strong></span> checks that MX records
113 refer to A or AAAA record (both in-zone and out-of-zone
114 hostnames). Mode <span><strong class="command">"local"</strong></span> only
115 checks MX records which refer to in-zone hostnames.
118 Mode <span><strong class="command">"full"</strong></span> checks that SRV records
119 refer to A or AAAA record (both in-zone and out-of-zone
120 hostnames). Mode <span><strong class="command">"local"</strong></span> only
121 checks SRV records which refer to in-zone hostnames.
124 Mode <span><strong class="command">"full"</strong></span> checks that delegation NS
125 records refer to A or AAAA record (both in-zone and out-of-zone
126 hostnames). It also checks that glue address records
127 in the zone match those advertised by the child.
128 Mode <span><strong class="command">"local"</strong></span> only checks NS records which
129 refer to in-zone hostnames or that some required glue exists,
130 that is when the nameserver is in a child zone.
133 Mode <span><strong class="command">"full-sibling"</strong></span> and
134 <span><strong class="command">"local-sibling"</strong></span> disable sibling glue
135 checks but are otherwise the same as <span><strong class="command">"full"</strong></span>
136 and <span><strong class="command">"local"</strong></span> respectively.
139 Mode <span><strong class="command">"none"</strong></span> disables the checks.
142 <dt><span class="term">-f <em class="replaceable"><code>format</code></em></span></dt>
144 Specify the format of the zone file.
145 Possible formats are <span><strong class="command">"text"</strong></span> (default)
146 and <span><strong class="command">"raw"</strong></span>.
148 <dt><span class="term">-F <em class="replaceable"><code>format</code></em></span></dt>
150 Specify the format of the output file specified.
151 Possible formats are <span><strong class="command">"text"</strong></span> (default)
152 and <span><strong class="command">"raw"</strong></span>.
153 For <span><strong class="command">named-checkzone</strong></span>,
154 this does not cause any effects unless it dumps the zone
157 <dt><span class="term">-k <em class="replaceable"><code>mode</code></em></span></dt>
159 Perform <span><strong class="command">"check-names"</strong></span> checks with the
160 specified failure mode.
161 Possible modes are <span><strong class="command">"fail"</strong></span>
162 (default for <span><strong class="command">named-compilezone</strong></span>),
163 <span><strong class="command">"warn"</strong></span>
164 (default for <span><strong class="command">named-checkzone</strong></span>) and
165 <span><strong class="command">"ignore"</strong></span>.
167 <dt><span class="term">-m <em class="replaceable"><code>mode</code></em></span></dt>
169 Specify whether MX records should be checked to see if they
170 are addresses. Possible modes are <span><strong class="command">"fail"</strong></span>,
171 <span><strong class="command">"warn"</strong></span> (default) and
172 <span><strong class="command">"ignore"</strong></span>.
174 <dt><span class="term">-M <em class="replaceable"><code>mode</code></em></span></dt>
176 Check if a MX record refers to a CNAME.
177 Possible modes are <span><strong class="command">"fail"</strong></span>,
178 <span><strong class="command">"warn"</strong></span> (default) and
179 <span><strong class="command">"ignore"</strong></span>.
181 <dt><span class="term">-n <em class="replaceable"><code>mode</code></em></span></dt>
183 Specify whether NS records should be checked to see if they
185 Possible modes are <span><strong class="command">"fail"</strong></span>
186 (default for <span><strong class="command">named-compilezone</strong></span>),
187 <span><strong class="command">"warn"</strong></span>
188 (default for <span><strong class="command">named-checkzone</strong></span>) and
189 <span><strong class="command">"ignore"</strong></span>.
191 <dt><span class="term">-o <em class="replaceable"><code>filename</code></em></span></dt>
193 Write zone output to <code class="filename">filename</code>.
194 If <code class="filename">filename</code> is <code class="filename">-</code> then
195 write to standard out.
196 This is mandatory for <span><strong class="command">named-compilezone</strong></span>.
198 <dt><span class="term">-s <em class="replaceable"><code>style</code></em></span></dt>
200 Specify the style of the dumped zone file.
201 Possible styles are <span><strong class="command">"full"</strong></span> (default)
202 and <span><strong class="command">"relative"</strong></span>.
203 The full format is most suitable for processing
204 automatically by a separate script.
205 On the other hand, the relative format is more
206 human-readable and is thus suitable for editing by hand.
207 For <span><strong class="command">named-checkzone</strong></span>
208 this does not cause any effects unless it dumps the zone
210 It also does not have any meaning if the output format
213 <dt><span class="term">-S <em class="replaceable"><code>mode</code></em></span></dt>
215 Check if a SRV record refers to a CNAME.
216 Possible modes are <span><strong class="command">"fail"</strong></span>,
217 <span><strong class="command">"warn"</strong></span> (default) and
218 <span><strong class="command">"ignore"</strong></span>.
220 <dt><span class="term">-t <em class="replaceable"><code>directory</code></em></span></dt>
222 Chroot to <code class="filename">directory</code> so that
224 directives in the configuration file are processed as if
225 run by a similarly chrooted named.
227 <dt><span class="term">-w <em class="replaceable"><code>directory</code></em></span></dt>
229 chdir to <code class="filename">directory</code> so that
231 filenames in master file $INCLUDE directives work. This
232 is similar to the directory clause in
233 <code class="filename">named.conf</code>.
235 <dt><span class="term">-D</span></dt>
237 Dump zone file in canonical format.
238 This is always enabled for <span><strong class="command">named-compilezone</strong></span>.
240 <dt><span class="term">-W <em class="replaceable"><code>mode</code></em></span></dt>
242 Specify whether to check for non-terminal wildcards.
243 Non-terminal wildcards are almost always the result of a
244 failure to understand the wildcard matching algorithm (RFC 1034).
245 Possible modes are <span><strong class="command">"warn"</strong></span> (default)
247 <span><strong class="command">"ignore"</strong></span>.
249 <dt><span class="term">zonename</span></dt>
251 The domain name of the zone being checked.
253 <dt><span class="term">filename</span></dt>
255 The name of the zone file.
