DESCRIPTION
named-checkzone 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.
-h
Print the usage summary and exit.
-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. If filename is - then write to
standard out. This is mandatory for named-compilezone.
-r mode
Check for records that are treated as different by DNSSEC but are
semantically equal in plain DNS. Possible modes are "fail", "warn"
(default) and "ignore".
-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.
