named-checkconf - named configuration file syntax checking tool
named-checkconf [-chjlvz] [-p [-x ]] [-t
named-checkconf checks the syntax, but not the semantics, of a
named configuration file. The file is parsed and checked for syntax
errors, along with all files included by it. If no file is specified,
/etc/named.conf is read by default.
Note: files that 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 to fail to run, even if named-checkconf was successful.
named-checkconf can be run on these files explicitly, however.
- Print the usage summary and exit.
- When loading a zonefile read the journal if it exists.
- List all the configured zones. Each line of output contains the zone name,
class (e.g. IN), view, and type (e.g. master or slave).
- Check "core" configuration only. This suppresses the loading of
plugin modules, and causes all parameters to plugin statements to
- Ignore warnings on deprecated options.
- Print out the named.conf and included files in canonical form if no
errors were detected. See also the -x option.
- -t directory
- Chroot to directory so that include directives in the configuration
file are processed as if run by a similarly chrooted named.
- Print the version of the named-checkconf program and exit.
- When printing the configuration files in canonical form, obscure shared
secrets by replacing them with strings of question marks ('?'). This
allows the contents of named.conf and related files to be shared
MDASH for example, when submitting bug reports MDASH without compromising
private data. This option cannot be used without -p.
- Perform a test load of all master zones found in named.conf.
- The name of the configuration file to be checked. If not specified, it
defaults to /etc/named.conf.
named-checkconf returns an exit status of 1 if errors were detected and 0
