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  con-
	      sidered 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. There-
	      fore, 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 use-
	      ful 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.
