21Synopsis
22~~~~~~~~
23
24:program:`named-checkconf` [**-achjlvz**] [**-p** [**-x** ]] [**-t** directory] {filename}
25
26Description
27~~~~~~~~~~~
28
29:program:`named-checkconf` checks the syntax, but not the semantics, of a
30:iscman:`named` configuration file. The file, along with all files included by it, is parsed and checked for syntax
31errors. If no file is specified,
32|named_conf| is read by default.
33
34Note: files that :iscman:`named` reads in separate parser contexts, such as
35``rndc.conf`` or ``rndc.key``, are not automatically read by
36:program:`named-checkconf`.  Configuration errors in these files may cause
37:iscman:`named` to fail to run, even if :program:`named-checkconf` was
38successful.  However, :program:`named-checkconf` can be run on these files
39explicitly.
40
41Options
42~~~~~~~
43
44.. option:: -a
45
46   Don't check the `dnssec-policy`'s DNSSEC key algorithms against
47   those supported by the crypto provider.  This is useful when checking
48   a `named.conf` intended to be run on another machine with possibly a
49   different set of supported DNSSEC key algorithms.
50
51.. option:: -h
52
53   This option prints the usage summary and exits.
54
55.. option:: -j
56
57   When loading a zonefile, this option instructs :iscman:`named` to read the journal if it exists.
58
59.. option:: -l
60
61   This option lists all the configured zones. Each line of output contains the zone
62   name, class (e.g. IN), view, and type (e.g. primary or secondary).
63
64.. option:: -c
65
66   This option specifies that only the "core" configuration should be checked. This suppresses the loading of
67   plugin modules, and causes all parameters to ``plugin`` statements to
68   be ignored.
69
70.. option:: -i
71
72   This option ignores warnings on deprecated options.
73
74.. option:: -p
75
76   This option prints out the :iscman:`named.conf` and included files in canonical form if
77   no errors were detected. See also the :option:`-x` option.
78
79.. option:: -t directory
80
81   This option instructs :iscman:`named` to chroot to ``directory``, so that ``include`` directives in the
82   configuration file are processed as if run by a similarly chrooted
83   :iscman:`named`.
84
85.. option:: -v
86
87   This option prints the version of the :program:`named-checkconf` program and exits.
88
89.. option:: -x
90
91   When printing the configuration files in canonical form, this option obscures
92   shared secrets by replacing them with strings of question marks
93   (``?``). This allows the contents of :iscman:`named.conf` and related files
94   to be shared - for example, when submitting bug reports -
95   without compromising private data. This option cannot be used without
96   :option:`-p`.
97
98.. option:: -z
99
100   This option performs a test load of all zones of type ``primary`` found in :iscman:`named.conf`.
101
102.. option:: filename
103
104   This indicates the name of the configuration file to be checked. If not specified,
105   it defaults to |named_conf|.
106
107Return Values
108~~~~~~~~~~~~~
109
110:program:`named-checkconf` returns an exit status of 1 if errors were detected
111and 0 otherwise.
