       dnssec-signzone signs a zone. It generates NXT and SIG records and pro-
       duces  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.

       -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 abso-
              lute start time is indicated by a number in YYYYMMDDHHMMSS nota-
              tion;  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 YYYYMMDDHH-
              MMSS 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-

       -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 sig-
              natures 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

       -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 indi-
              cates that keyboard input should be used.

       -t     Print statistics at completion.

       -v level
              Sets the debugging level.

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

       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

       The  following command signs the zone with the DSA key gen-
       erated 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.,  the
       following command would be issued:

       dnssec-signzone -o

       The command would print a string of the form:

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