dnssec-signzone - DNSSEC zone signing tool
dnssec-signzone [-ahpt] [-c class] [-d directory] [-s start-time] [-e end-time] [-f output-file] [-i interval] [-n nthreads] [-o origin]
[-r randomdev] [-v level] zonefile [key...]
The dnssec-signzone utility signs a zone. It generates NXT and SIG records and produces a signed version of the zone. If there is a signed-
key file from the zone's parent, the parent's signatures is incorporated into the generated signed zone file. The security status of dele-
gations from 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.
The following options are supported:
-a Verify all generated signatures.
-c class Specify the DNS class of the zone.
-d directory Look for signedkey files in directory.
-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 relative 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 Specify the cycle interval as an offset from the current time (in seconds). When a previously signed zone is passed as
input, records could be resigned. If a SIG record expires after the cycle interval, it is retained. Otherwise, it is con-
sidered to be expiring soon and will be replaced. The default cycle interval is one quarter of the difference between the
signature end and start times. 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. Any existing SIG records due to expire in less than 7.5 days
would be replaced.
-n ncpus Specify the number of threads to use. By default, one thread is started for each detected CPU.
-o origin Specify 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 can
be useful when signing large zones or when the entropy source is limited.
-r randomdev Specify 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. The randomdev argument 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.
-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.
-t Print statistics at completion.
-v level Set the debugging level.
The following options are supported:
zonefile The file containing the zone to be signed. This file sets the debugging level.
key The keys used to sign the zone. If no keys are specified, the default is all zone keys that have private key files in the
Example 1: Sign a zone with a DSA key.
The following command signs the example.com zone with the DSA key generated in the example on the dnssec-keygen(1M) manual 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.
dnssec-signzone -o example.com db.example.com
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
