DESCRIPTIONdnssec-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 par-
ent'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 direc-
tory
-s start-time
Specify the date and time when the generated SIG
records become valid. This can be either an abso-
lute 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
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
When a previously signed zone is passed as input,
records may be resigned. The interval option speci-
fies the cycle interval as an offset from the
current time (in seconds). If a SIG record expires
after the cycle interval, it is retained. Other-
wise, 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 operat-
ing system does not provide a /dev/random or equiv-
alent 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 pri-
vate 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 fol-
lowing command would be issued:
dnssec-signzone-o example.com db.example.com Kexam-
ple.com.+003+26160
The command would print a string of the form:
In this example, dnssec-signzone creates the file db.exam-
ple.com.signed. This file should be referenced in a zone
statement in a named.conf file.
