checks the syntax and integrity of a zone file. It performs the same checks as
named
does when loading a zone. This makes
named-checkzone
useful for checking zone files before configuring them into a name server.
named-compilezone
is similar to
named-checkzone, but it always dumps the zone contents to a specified file in a specified format. Additionally, it applies stricter check levels by default, since the dump output will be used as an actual zone file loaded by
named. When manually specified otherwise, the check levels must at least be as strict as those specified in the
named
configuration file.
OPTIONS
-d
Enable debugging.
-q
Quiet mode - exit code only.
-v
Print the version of the
named-checkzone
program and exit.
-j
When loading the zone file read the journal if it exists.
-c class
Specify the class of the zone. If not specified "IN" is assumed.
-i mode
Perform post-load zone integrity checks. Possible modes are
"full"
(default),
"full-sibling",
"local",
"local-sibling"
and
"none".
Mode
"full"
checks that MX records refer to A or AAAA record (both in-zone and out-of-zone hostnames). Mode
"local"
only checks MX records which refer to in-zone hostnames.
Mode
"full"
checks that SRV records refer to A or AAAA record (both in-zone and out-of-zone hostnames). Mode
"local"
only checks SRV records which refer to in-zone hostnames.
Mode
"full"
checks that delegation NS records refer to A or AAAA record (both in-zone and out-of-zone hostnames). It also checks that glue address records in the zone match those advertised by the child. Mode
"local"
only checks NS records which refer to in-zone hostnames or that some required glue exists, that is when the nameserver is in a child zone.
Mode
"full-sibling"
and
"local-sibling"
disable sibling glue checks but are otherwise the same as
"full"
and
"local"
respectively.
Mode
"none"
disables the checks.
-f format
Specify the format of the zone file. Possible formats are
"text"
(default) and
"raw".
-F format
Specify the format of the output file specified. Possible formats are
"text"
(default) and
"raw". For
named-checkzone, this does not cause any effects unless it dumps the zone contents.
-k mode
Perform
"check-names"
checks with the specified failure mode. Possible modes are
"fail"
(default for
named-compilezone),
"warn"
(default for
named-checkzone) and
"ignore".
-m mode
Specify whether MX records should be checked to see if they are addresses. Possible modes are
"fail",
"warn"
(default) and
"ignore".
-M mode
Check if a MX record refers to a CNAME. Possible modes are
"fail",
"warn"
(default) and
"ignore".
-n mode
Specify whether NS records should be checked to see if they are addresses. Possible modes are
"fail"
(default for
named-compilezone),
"warn"
(default for
named-checkzone) and
"ignore".
-o filename
Write zone output to
filename. This is mandatory for
named-compilezone.
-s style
Specify the style of the dumped zone file. Possible styles are
"full"
(default) and
"relative". The full format is most suitable for processing automatically by a separate script. On the other hand, the relative format is more human-readable and is thus suitable for editing by hand. For
named-checkzone
this does not cause any effects unless it dumps the zone contents. It also does not have any meaning if the output format is not text.
-S mode
Check if a SRV record refers to a CNAME. Possible modes are
"fail",
"warn"
(default) and
"ignore".
-t directory
Chroot to
directory
so that include directives in the configuration file are processed as if run by a similarly chrooted named.
-w directory
chdir to
directory
so that relative filenames in master file $INCLUDE directives work. This is similar to the directory clause in
named.conf.
-D
Dump zone file in canonical format. This is always enabled for
named-compilezone.
-W mode
Specify whether to check for non-terminal wildcards. Non-terminal wildcards are almost always the result of a failure to understand the wildcard matching algorithm (RFC 1034). Possible modes are
"warn"
(default) and
"ignore".
zonename
The domain name of the zone being checked.
filename
The name of the zone file.
RETURN VALUES
named-checkzone
returns an exit status of 1 if errors were detected and 0 otherwise.
