DESCRIPTION

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

OPTIONS

36       -d
37           Enable debugging.
38
39       -h
40           Print the usage summary and exit.
41
42       -q
43           Quiet mode - exit code only.
44
45       -v
46           Print the version of the named-checkzone program and exit.
47
48       -j
49           When loading a zone file, read the journal if it exists. The
50           journal file name is assumed to be the zone file name appended with
51           the string .jnl.
52
53       -J filename
54           When loading the zone file read the journal from the given file, if
55           it exists. (Implies -j.)
56
57       -c class
58           Specify the class of the zone. If not specified, "IN" is assumed.
59
60       -i mode
61           Perform post-load zone integrity checks. Possible modes are "full"
62           (default), "full-sibling", "local", "local-sibling" and "none".
63
64           Mode "full" checks that MX records refer to A or AAAA record (both
65           in-zone and out-of-zone hostnames). Mode "local" only checks MX
66           records which refer to in-zone hostnames.
67
68           Mode "full" checks that SRV records refer to A or AAAA record (both
69           in-zone and out-of-zone hostnames). Mode "local" only checks SRV
70           records which refer to in-zone hostnames.
71
72           Mode "full" checks that delegation NS records refer to A or AAAA
73           record (both in-zone and out-of-zone hostnames). It also checks
74           that glue address records in the zone match those advertised by the
75           child. Mode "local" only checks NS records which refer to in-zone
76           hostnames or that some required glue exists, that is when the
77           nameserver is in a child zone.
78
79           Mode "full-sibling" and "local-sibling" disable sibling glue checks
80           but are otherwise the same as "full" and "local" respectively.
81
82           Mode "none" disables the checks.
83
84       -f format
85           Specify the format of the zone file. Possible formats are "text"
86           (default), "raw", and "map".
87
88       -F format
89           Specify the format of the output file specified. For
90           named-checkzone, this does not cause any effects unless it dumps
91           the zone contents.
92
93           Possible formats are "text" (default), which is the standard
94           textual representation of the zone, and "map", "raw", and "raw=N",
95           which store the zone in a binary format for rapid loading by named.
96           "raw=N" specifies the format version of the raw zone file: if N is
97           0, the raw file can be read by any version of named; if N is 1, the
98           file can be read by release 9.9.0 or higher; the default is 1.
99
100       -k mode
101           Perform "check-names" checks with the specified failure mode.
102           Possible modes are "fail" (default for named-compilezone), "warn"
103           (default for named-checkzone) and "ignore".
104
105       -l ttl
106           Sets a maximum permissible TTL for the input file. Any record with
107           a TTL higher than this value will cause the zone to be rejected.
108           This is similar to using the max-zone-ttl option in named.conf.
109
110       -L serial
111           When compiling a zone to "raw" or "map" format, set the "source
112           serial" value in the header to the specified serial number. (This
113           is expected to be used primarily for testing purposes.)
114
115       -m mode
116           Specify whether MX records should be checked to see if they are
117           addresses. Possible modes are "fail", "warn" (default) and
118           "ignore".
119
120       -M mode
121           Check if a MX record refers to a CNAME. Possible modes are "fail",
122           "warn" (default) and "ignore".
123
124       -n mode
125           Specify whether NS records should be checked to see if they are
126           addresses. Possible modes are "fail" (default for
127           named-compilezone), "warn" (default for named-checkzone) and
128           "ignore".
129
130       -o filename
131           Write zone output to filename. If filename is - then write to
132           standard out. This is mandatory for named-compilezone.
133
134       -r mode
135           Check for records that are treated as different by DNSSEC but are
136           semantically equal in plain DNS. Possible modes are "fail", "warn"
137           (default) and "ignore".
138
139       -s style
140           Specify the style of the dumped zone file. Possible styles are
141           "full" (default) and "relative". The full format is most suitable
142           for processing automatically by a separate script. On the other
143           hand, the relative format is more human-readable and is thus
144           suitable for editing by hand. For named-checkzone this does not
145           cause any effects unless it dumps the zone contents. It also does
146           not have any meaning if the output format is not text.
147
148       -S mode
149           Check if a SRV record refers to a CNAME. Possible modes are "fail",
150           "warn" (default) and "ignore".
151
152       -t directory
153           Chroot to directory so that include directives in the configuration
154           file are processed as if run by a similarly chrooted named.
155
156       -T mode
157           Check if Sender Policy Framework (SPF) records exist and issues a
158           warning if an SPF-formatted TXT record is not also present.
159           Possible modes are "warn" (default), "ignore".
160
161       -w directory
162           chdir to directory so that relative filenames in master file
163           $INCLUDE directives work. This is similar to the directory clause
164           in named.conf.
165
166       -D
167           Dump zone file in canonical format. This is always enabled for
168           named-compilezone.
169
170       -W mode
171           Specify whether to check for non-terminal wildcards. Non-terminal
172           wildcards are almost always the result of a failure to understand
173           the wildcard matching algorithm (RFC 1034). Possible modes are
174           "warn" (default) and "ignore".
175
176       zonename
177           The domain name of the zone being checked.
178
179       filename
180           The name of the zone file.
181

RETURN VALUES

183       named-checkzone returns an exit status of 1 if errors were detected and
184       0 otherwise.
