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 a zone file, read the journal if it exists.
The journal file name is assumed to be the zone file

NAMED-CHECKZONE(8) BIND9 NAMED-CHECKZONE(8)
name appended with the string .jnl.
-J filename
When loading the zone file read the journal from the
given file, if it exists. (Implies -j.)
-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), "raw", and "map".
-F format
Specify the format of the output file specified. For
named-checkzone, this does not cause any effects unless
it dumps the zone contents.
Possible formats are "text" (default), which is the
standard textual representation of the zone, and "map",
"raw", and "raw=N", which store the zone in a binary
format for rapid loading by named. "raw=N" specifies
ISC Last change: 2014-02-19 2
NAMED-CHECKZONE(8) BIND9 NAMED-CHECKZONE(8)
the format version of the raw zone file: if N is 0, the
raw file can be read by any version of named; if N is 1,
the file can be read by release 9.9.0 or higher; the
default is 1.
-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".
-l ttl
Sets a maximum permissible TTL for the input file. Any
record with a TTL higher than this value will cause the
zone to be rejected. This is similar to using the
max-zone-ttl option in named.conf.
-L serial
When compiling a zone to "raw" or "map" format, set the
"source serial" value in the header to the specified
serial number. (This is expected to be used primarily
for testing purposes.)
-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
ISC Last change: 2014-02-19 3
NAMED-CHECKZONE(8) BIND9 NAMED-CHECKZONE(8)
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.
-T mode
Check if Sender Policy Framework (SPF) records exist and
issues a warning if an SPF-formatted TXT record is not
also present. Possible modes are "warn" (default),
"ignore".
-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.
