Patches to dnsDataGen.pl with new writers

Hello all,

I hope I am posting to the right list.  If not, please let me know if there
is a better place to post.

Recently I found myself benchmarking a variety of authoritative DNS servers,
but quickly became frustrated at the amount of time I was spending on
creating large amounts of 'random' DNS data in formats suitable for each.
Luckily, I found the excellent dnsDataGen.pl tool, which helped
tremendously.

I decided to create some new 'writers' modules that were particularly
relevant to my benchmarking efforts and I thought I should share them with
the world in case they are able to help someone else someday.

The patches can be found here:  http://www.joeym.net/

A summary of the changes:

- Slight modification to dnsDataGen.pl itself so that it always creates the
SOA record first when creating a new zone.  This was helpful for the writers
I created because many of them build a set of commands to feed into various
SQL DB's which require that the zone exists before records can be added to
it.

- The following new 'writers' (I created a new directory called
"contrib/writers" to store these, as recommend on the bind-dlz website):
  -- contrib::writers::mydns::file
  -- contrib::writers::powerdns::xdb
  -- contrib::writers::powerdns::sqlite3
  -- contrib::writers::powerdns::gmysql
  -- contrib::writers::windowsdns::file

These should each be fairly self-explanatory for the most part if you're
familiar with MyDNS, PowerDNS, and Windows DNS.  Mostly they just create SQL
files that can be directly imported into mysql (ie: cat file |mysql dbname).
The Windows DNS writer creates a batch file that calls "dnscmd" to create
records in Active Directory.  I've only tested this writer with
AD-integrated zones, but it may work for other zone types.

The PowerDNS XDB writer's output is intended to be fed into the 'xdb-fill'
tool that comes with PowerDNS.

Everything is wrapped up in 1 patch file, available at
http://www.joeym.net/bind-dlz-patches/bind-dlz-jmiller.patch

I've only tested each of these for basic functionality, so I cannot
guarantee they'll work with all versions or in all scenarios, but so far
they have been a big time-saver for the various benchmarking I've been
doing.

I'm not sure if maintenance is still being done on BIND-DLZ, dnsDataGen.pl,
or the DLZPerfTools.  If so, and these patches are useful, feel free to
include them in a future release.  I will attempt to maintain them on my own
webserver as long as possible.



Thanks,
Joe
