PROGRAM:

NAME


ldns-gen-zone - read a zonefile and print it while adding DS records and extra RR's

SYNOPSIS


ldns-gen-zone ZONEFILE

DESCRIPTION


ldns-gen-zone reads a DNS zone file and prints it.

It is build for speed, not for a nice formatting. The output has one resource record per
line and no pretty-printing makeup.

DNSSEC data (NSEC, NSEC3, RRSIG or DNSKEY) is not stripped. You may want to use ldns-read-
zone for that. Existing DS records are also not stripped.

The idea is to use this tool for quickly generating a representative artificial zonefile
from a real zonefile, to use it for testing purposes.

OPTIONS


-a NUM Adds NUM extra artificial NS RRSets to the output. The RRSets owner names start
with 'xn--' in an attempt to ensure uniqueness (nl.-zone does not support IDN's -
and this tool was written with that knowledge in mind).

An artificial NS RRSet has two NS records; ns1.example.com and ns2.example.com.

-p NUM Add NUM% of DS RRSets to the NS RRSets (anywhere between 1-4 DS records per RRSet).

-o ORIGIN
Sets an $ORIGIN, which can be handy if the one in the zonefile is set to '@' for
example. If there is an $ORIGIN in the zonefile, this option will silently be
ignored.

-s This is the recommended way of processing large zones that are already sorted and
canonicalized (ie lowercase). It skips the sorting and canonicalization step that
is required for properly grouping RRSets together (before adding any DS records to
them. Skipping this step will speed things up.

It is not recommended to use this option if you want to add DS records to unsorted,
non-canonicalized zones.

-h Show usage and exit.

-v Show version and exit.

EXAMPLES


ldns-gen-zone -a 100000 -p 10 -s ./zonefile.txt
Read a zonefile, add 100.000 artificial NS RRSets and 10% of DS records, print it
to standard output. Don't sort (will only work well if the input zonefile is
already sorted and canonicalized).

ldns-gen-zone -p 10 -s -o nl zonefile.txt | named-compilezone -s relative -i none -o
zonefile_10.txt nl /dev/stdin
This creates a nicely formatted zone file with the help of named-compilezone. It
adds 10% DS records to the .nl zone, reformats it and saves it as zonefile_10.txt.
