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 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 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 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.
