DNS Performance Testing Tools: My Writer Modules

The BIND-DLZ project publishes an excellent set of performance testing tools which make it easy to generate a lot of fake DNS data for a variety of DNS server types.

I have even extended this excellent tool set by creating a few new “writer” modules:

  • contrib::writers::mydns::file
  • contrib::writers::powerdns::xdb
  • contrib::writers::powerdns::sqlite3
  • contrib::writers::powerdns::gmysql
  • contrib::writers::windowsdns::file

Additionally, I modified the original dnsDataGen.pl script slightly so that the SOA record is always created first when generating a new zone.  This was necessary for most of the new writer modules to function properly.

  • DLZPerfTools-1.1-jmiller-contrib.tar.gz -The original upstream version of DLZPerfTools-1.1 with my new modules and changes already applied.
  • bind-dlz-jmiller.patch – A diff file that can be applied against the upstream DLZPerfTools-1.1.tar.gz
  • sample.conf – A sample config file for use with dnsDataGen.pl demonstrating how to use each of the new writer modules.
  • dns-dict – My personal list of random words that I use to feed into dnsDataGen.pl
  • announcement.txt -Announcement email to the bind-dlz-testers mailing list. This has a little bit more info about the patch and the new writer modules, if you need it.
