DESCRIPTION

       named-compilezone checks the syntax and integrity of a  zone  file,  and  dumps  the  zone
       contents  to  a  specified  file in a specified format.  It applies strict check levels by
       default, since the dump output is 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     This option enables debugging.

       -h     This option prints the usage summary and exits.

       -q     This option sets quiet mode, which only sets an exit code to indicate successful or
              failed completion.

       -v     This option prints the version of the named-checkzone program and exits.

       -j     When loading a zone file, this option tells named to read the journal if it exists.
              The journal file name is assumed to be the zone file  name  with  the  string  .jnl
              appended.

       -J filename
              When  loading  the  zone file, this option tells named to read the journal from the
              given file, if it exists. This implies -j.

       -c class
              This option specifies the class of the zone. If not specified, IN is assumed.

       -i mode
              This option performs post-load zone integrity checks. Possible modes are full  (the
              default), full-sibling, local, local-sibling, and none.

              Mode  full  checks  that  MX  records  refer to A or AAAA records (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 records (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 records (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 verifies that some required glue exists,  i.e.,  when
              the name server is in a child zone.

              Modes 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
              This option specifies the format of the zone file. Possible formats are  text  (the
              default), and raw.

       -F format
              This option specifies the format of the output file specified. For named-checkzone,
              this does not have any effect unless it dumps the zone contents.

              Possible  formats  are  text  (the  default),  which  is   the   standard   textual
              representation  of  the  zone,  and 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 only be read by release 9.9.0 or higher. The default is 1.

       -k mode
              This option performs check-names checks with the specified failure mode.   Possible
              modes are fail (the default), warn, and ignore.

       -l ttl This  option  sets  a maximum permissible TTL for the input file. Any record with a
              TTL higher than this value causes 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 format, this option sets the "source serial" value in
              the header to the specified serial number. This is expected to  be  used  primarily
              for testing purposes.

       -m mode
              This  option  specifies  whether  MX  records  should be checked to see if they are
              addresses. Possible modes are fail, warn (the default), and ignore.

       -M mode
              This option checks whether a MX record refers to a CNAME. Possible modes are  fail,
              warn (the default), and ignore.

       -n mode
              This  option  specifies  whether  NS  records  should be checked to see if they are
              addresses. Possible modes are fail (the default), warn,  and ignore.

       -o filename
              This option writes the zone output to filename. If filename is  -,  then  the  zone
              output is written to standard output. This is mandatory for named-compilezone.

       -r mode
              This  option  checks  for  records  that are treated as different by DNSSEC but are
              semantically equal in plain DNS. Possible modes are fail, warn (the  default),  and
              ignore.

       -s style
              This  option  specifies the style of the dumped zone file. Possible styles are full
              (the default) and relative.  The  full  format  is  most  suitable  for  processing
              automatically by a separate script.  The relative format is more human-readable and
              is thus suitable for editing by hand.

       -S mode
              This option checks whether an SRV record refers to  a  CNAME.  Possible  modes  are
              fail, warn (the default), and ignore.

       -t directory
              This  option  tells named to chroot to directory, so that include directives in the
              configuration file are processed as if run by a similarly chrooted named.

       -T mode
              This option checks whether Sender Policy Framework (SPF) records exist and issues a
              warning if an SPF-formatted TXT record is not also present. Possible modes are warn
              (the default) and ignore.

       -w directory
              This option instructs named to chdir to directory, so that  relative  filenames  in
              master  file  $INCLUDE  directives work. This is similar to the directory clause in
              named.conf.

       -D     This option dumps the zone file in canonical format. This  is  always  enabled  for
              named-compilezone.

       -W mode
              This  option  specifies  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 4592). Possible modes are warn (the default) and ignore.

       zonename
              This indicates the domain name of the zone being checked.

       filename
              This is the name of the zone file.

RETURN VALUES

       named-compilezone returns an exit status of 1 if errors were detected and 0 otherwise.
