[OCLUG-Tech] Ozymandns or NSTX

Has anyone gotten Ozymandns or NSTX to work?  Are they just a cruel hoax
created to fool those of us with little enough DNS knowledge to believe
such a thing is actually possible?

Ozymandns:

$ sudo ./nomde.pl -i 0.0.0.0 metal.modernduck.com
Dealing with ...

NSTX:

No errors, but nothing happens.  A steady stream of queries can be seen
using tcpdump, even when nothing is running:

Any ideas?
