ldns-gen-zone

ldns-gen-zone(1)					      General Commands Manual						  ldns-gen-zone(1)

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  pur-
       poses.

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.

BUGS

       Only undiscovered ones.

CAVEATS

       May require a machine with a considerable amount of memory for large zone files.

       Fake  DS records hashes are generated as digest type SHA-256 (RFC4509). Be aware not to change the DIGESTTYPE #define in the source code in
       anything else but 2 if you want to keep things realistic.

       Despite a number of efforts, this program is still not the fastest in the world.
