named-checkconf - Man Page
named configuration file syntax checking tool
Synopsis
named-checkconf [-chjlvz] [-p [-x ]] [-t directory] {filename}
Description
named-checkconf checks the syntax, but not the semantics, of a named <#std-iscman-named> configuration file. The file, along with all files included by it, is parsed and checked for syntax errors. If no file is specified, /etc/named.conf is read by default.
Note: files that named <#std-iscman-named> reads in separate parser contexts, such as rndc.key and bind.keys, are not automatically read by named-checkconf. Configuration errors in these files may cause named <#std-iscman-named> to fail to run, even if named-checkconf was successful. However, named-checkconf can be run on these files explicitly.
Options
- -h
This option prints the usage summary and exits.
- -j
When loading a zonefile, this option instructs named <#std-iscman-named> to read the journal if it exists.
- -l
This option lists all the configured zones. Each line of output contains the zone name, class (e.g. IN), view, and type (e.g. primary or secondary).
- -c
This option specifies that only the "core" configuration should be checked. This suppresses the loading of plugin modules, and causes all parameters to plugin statements to be ignored.
- -i
This option ignores warnings on deprecated options.
- -p
This option prints out the named.conf <#std-iscman-named.conf> and included files in canonical form if no errors were detected. See also the -x option.
- -t directory
This option instructs named <#std-iscman-named> to chroot to directory, so that include directives in the configuration file are processed as if run by a similarly chrooted named <#std-iscman-named>.
- -v
This option prints the version of the named-checkconf program and exits.
- -x
When printing the configuration files in canonical form, this option obscures shared secrets by replacing them with strings of question marks (?). This allows the contents of named.conf <#std-iscman-named.conf> and related files to be shared - for example, when submitting bug reports - without compromising private data. This option cannot be used without -p.
- -z
This option performs a test load of all zones of type primary found in named.conf <#std-iscman-named.conf>.
- filename
This indicates the name of the configuration file to be checked. If not specified, it defaults to /etc/named.conf.
Return Values
named-checkconf returns an exit status of 1 if errors were detected and 0 otherwise.
