Thomas,

        I would recommend that you use PolyMix-3 and the step-by-step
instructions at http://www.measurement-factory.com/docs/PolyMix-3/
If you have to use PolyMix-2, try to follow these steps:
http://bakeoff.ircache.net/N02/howto.txt

It is difficult to say what is wrong with your setup based on the
information you have supplied. Here are a few guesses that might help:

        - Polygraph does not understand FQDNs yet, only IP addresses
          must be used

        - If you have one PolyMix-2,3 robot only (one IP address),
          you will get 0.4 req/sec load at most; create more
          robots (preferrably via adding IP aliases) to increase
          the load

        - Make sure you can talk to Polygraph servers from Polygraph
          client machine using telnet

Good luck,

Alex.
