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.  It also applies stricter 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), raw, and map.

       -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 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 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  for  named-compilezone),  warn  (the  default  for
              named-checkzone), 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 or map 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 for named-compilezone),  warn  (the
              default for named-checkzone), 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. For named-checkzone, this does not have any
              effect unless it dumps the zone contents. It also does not have any meaning if  the
              output format is not text.

       -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 1034). 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-checkzone returns an exit status of 1 if errors were detected and 0 otherwise.
