DNSSEC-MAKEKEYSET linux command manual
dnssec-makekeyset - DNSSEC zone signing tool
dnssec-makekeyset [ -a ] [ -s start-time ] [ -e end-time ] [ -h ]
[ -p ] [ -r randomdev ] [ -tttl ] [ -v level ] key...
dnssec-makekeyset generates a key set from one or more keys created by
dnssec-keygen. It creates a file containing a KEY record for each key,
and self-signs the key set with each zone key. The output file is of
the form keyset-nnnn., where nnnn is the zone name.
-a Verify all generated signatures.
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 sec-
onds from the current time. If no start-time is specified, the
current time is used.
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.
-h Prints a short summary of the options and arguments to dnssec-
-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
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 spec-
ifies the name of a character device or file containing random
data to be used instead of the default. The special value key-
board indicates that keyboard input should be used.
-t ttl Specify the TTL (time to live) of the KEY and SIG records. The
default is 3600 seconds.
Sets the debugging level.
