DNSSEC-SIGNZONE(8)


NAME

  dnssec-signzone - DNSSEC zone signing tool


SYNOPSIS

  dnssec-signzone [ -a ]  [ -c class ]	[ -d directory ]  [ -s start-time ]
  [ -e end-time ]  [ -f output-file ]  [ -h ]  [ -i interval ]	[ -n nthreads
  ]  [ -o origin ]  [ -p ]  [ -r randomdev ]  [ -t ]  [ -v level ]  zonefile
  [ key... ]


DESCRIPTION

  dnssec-signzone signs a zone. It generates NXT and SIG records and produces
  a signed version of the zone. If there is a signedkey file from the zone's
  parent, the parent's signatures will be incorporated into the generated
  signed zone file. The security status of delegations from the the signed
  zone (that is, whether the child zones are secure or not) is determined by
  the presence or absence of a signedkey file for each child zone.


OPTIONS

  -a   Verify all generated signatures.

  -c class
       Specifies the DNS class of the zone.

  -d directory
       Look for signedkey files in directory as the directory

  -s start-time
       Specify the date and time when the generated SIG records become valid.
       This can be either an absolute or relative time. An absolute start
       time is indicated by a number in YYYYMMDDHHMMSS notation;
       20000530144500 denotes 14:45:00 UTC on May 30th, 2000. A relative
       start time is indicated by +N, which is N seconds from the current
       time.  If no start-time is specified, the current time is used.

  -e end-time
       Specify the date and time when the generated SIG records expire. As
       with start-time, an absolute time is indicated in YYYYMMDDHHMMSS
       notation. A time relative to the start time is indicated with +N,
       which is N seconds from the start time. A time realtive to the current
       time is indicated with now+N. If no end-time is specified, 30 days
       from the start time is used as a default.

  -f output-file
       The name of the output file containing the signed zone. The default is
       to append .signed to the input file.

  -h   Prints a short summary of the options and arguments to dnssec-
       signzone.

  -i interval
       When a previously signed zone is passed as input, records may be
       resigned. The interval option specifies the cycle interval as an
       offset from the current time (in seconds). If a SIG record expires
       after the cycle interval, it is retained. Otherwise, it is considered
       to be expiring soon, and it will be replaced.

       The default cycle interval is one quarter of the difference between
       the signature end and start times. So if neither end-time or start-
       time are specified, dnssec-signzone generates signatures that are
       valid for 30 days, with a cycle interval of 7.5 days. Therefore, if
       any existing SIG records are due to expire in less than 7.5 days, they
       would be replaced.

  -n ncpus
       Specifies the number of threads to use. By default, one thread is
       started for each detected CPU.

  -o origin
       The zone origin. If not specified, the name of the zone file is
       assumed to be the origin.

  -p   Use pseudo-random data when signing the zone. This is faster, but less
       secure, than using real random data. This option may be useful when
       signing large zones or when the entropy source is limited.

  -r randomdev
       Specifies the source of randomness. If the operating system does not
       provide a /dev/random or equivalent device, the default source of
       randomness is keyboard input. randomdev specifies the name of a
       character device or file containing random data to be used instead of
       the default. The special value keyboard indicates that keyboard input
       should be used.

  -t   Print statistics at completion.

  -v level
       Sets the debugging level.

  zonefile
       The file containing the zone to be signed.  Sets the debugging level.

  key  The keys used to sign the zone. If no keys are specified, the default
       all zone keys that have private key files in the current directory.


EXAMPLE

  The following command signs the example.com zone with the DSA key generated
  in the dnssec-keygen man page. The zone's keys must be in the zone. If
  there are signedkey files associated with this zone or any child zones,
  they must be in the current directory.  example.com, the following command
  would be issued:

  dnssec-signzone -o example.com db.example.com Kexample.com.+003+26160

  The command would print a string of the form:

  In this example, dnssec-signzone creates the file db.example.com.signed.
  This file should be referenced in a zone statement in a named.conf file.
