21 named-checkzone checks the syntax and integrity of a zone file. It per‐
22 forms the same checks as named does when loading a zone. This makes
23 named-checkzone useful for checking zone files before configuring them
24 into a name server.
25 named-compilezone is similar to named-checkzone, but it always dumps
27 the zone contents to a specified file in a specified format. It also
28 applies stricter check levels by default, since the dump output is used
29 as an actual zone file loaded by named. When manually specified other‐
30 wise, the check levels must at least be as strict as those specified in
31 the named configuration file.

34 -d This option enables debugging.
35 -h This option prints the usage summary and exits.
37 -q This option sets quiet mode, which only sets an exit code to in‐
39 dicate successful or failed completion.
40 -v This option prints the version of the named-checkzone program
42 and exits.
43 -j When loading a zone file, this option tells named to read the
45 journal if it exists. The journal file name is assumed to be the
46 zone file name with the string .jnl appended.
47 -J filename
49 When loading the zone file, this option tells named to read the
50 journal from the given file, if it exists. This implies -j.
51 -c class
53 This option specifies the class of the zone. If not specified,
54 IN is assumed.
55 -i mode
57 This option performs post-load zone integrity checks. Possible
58 modes are full (the default), full-sibling, local, local-sib‐
59 ling, and none.
60 Mode full checks that MX records refer to A or AAAA records
62 (both in-zone and out-of-zone hostnames). Mode local only checks
63 MX records which refer to in-zone hostnames.
64 Mode full checks that SRV records refer to A or AAAA records
66 (both in-zone and out-of-zone hostnames). Mode local only checks
67 SRV records which refer to in-zone hostnames.
68 Mode full checks that delegation NS records refer to A or AAAA
70 records (both in-zone and out-of-zone hostnames). It also checks
71 that glue address records in the zone match those advertised by
72 the child. Mode local only checks NS records which refer to
73 in-zone hostnames or verifies that some required glue exists,
74 i.e., when the name server is in a child zone.
75 Modes full-sibling and local-sibling disable sibling glue
77 checks, but are otherwise the same as full and local, respec‐
78 tively.
79 Mode none disables the checks.
81 -f format
83 This option specifies the format of the zone file. Possible for‐
84 mats are text (the default), raw, and map.
85 -F format
87 This option specifies the format of the output file specified.
88 For named-checkzone, this does not have any effect unless it
89 dumps the zone contents.
90 Possible formats are text (the default), which is the standard
92 textual representation of the zone, and map, raw, and raw=N,
93 which store the zone in a binary format for rapid loading by
94 named. raw=N specifies the format version of the raw zone file:
95 if N is 0, the raw file can be read by any version of named; if
96 N is 1, the file can only be read by release 9.9.0 or higher.
97 The default is 1.
98 -k mode
100 This option performs check-names checks with the specified fail‐
101 ure mode. Possible modes are fail (the default for named-com‐
102 pilezone), warn (the default for named-checkzone), and ignore.
103 -l ttl This option sets a maximum permissible TTL for the input file.
105 Any record with a TTL higher than this value causes the zone to
106 be rejected. This is similar to using the max-zone-ttl option in
107 named.conf.
108 -L serial
110 When compiling a zone to raw or map format, this option sets the
111 "source serial" value in the header to the specified serial num‐
112 ber. This is expected to be used primarily for testing purposes.
113 -m mode
115 This option specifies whether MX records should be checked to
116 see if they are addresses. Possible modes are fail, warn (the
117 default), and ignore.
118 -M mode
120 This option checks whether a MX record refers to a CNAME. Possi‐
121 ble modes are fail, warn (the default), and ignore.
122 -n mode
124 This option specifies whether NS records should be checked to
125 see if they are addresses. Possible modes are fail (the default
126 for named-compilezone), warn (the default for named-checkzone),
127 and ignore.
128 -o filename
130 This option writes the zone output to filename. If filename is
131 -, then the zone output is written to standard output. This is
132 mandatory for named-compilezone.
133 -r mode
135 This option checks for records that are treated as different by
136 DNSSEC but are semantically equal in plain DNS. Possible modes
137 are fail, warn (the default), and ignore.
138 -s style
140 This option specifies the style of the dumped zone file. Possi‐
141 ble styles are full (the default) and relative. The full format
142 is most suitable for processing automatically by a separate
143 script. The relative format is more human-readable and is thus
144 suitable for editing by hand. For named-checkzone, this does not
145 have any effect unless it dumps the zone contents. It also does
146 not have any meaning if the output format is not text.
147 -S mode
149 This option checks whether an SRV record refers to a CNAME. Pos‐
150 sible modes are fail, warn (the default), and ignore.
151 -t directory
153 This option tells named to chroot to directory, so that include
154 directives in the configuration file are processed as if run by
155 a similarly chrooted named.
156 -T mode
158 This option checks whether Sender Policy Framework (SPF) records
159 exist and issues a warning if an SPF-formatted TXT record is not
160 also present. Possible modes are warn (the default) and ignore.
161 -w directory
163 This option instructs named to chdir to directory, so that rela‐
164 tive filenames in master file $INCLUDE directives work. This is
165 similar to the directory clause in named.conf.
166 -D This option dumps the zone file in canonical format. This is al‐
168 ways enabled for named-compilezone.
169 -W mode
171 This option specifies whether to check for non-terminal wild‐
172 cards. Non-terminal wildcards are almost always the result of a
173 failure to understand the wildcard matching algorithm (RFC
174 1034). Possible modes are warn (the default) and ignore.
175 zonename
177 This indicates the domain name of the zone being checked.
178 filename
180 This is the name of the zone file.
181
183 named-checkzone returns an exit status of 1 if errors were detected and
184 0 otherwise.
