First of all, check your setup before starting a test: Make sure that
you can ping DNS server IP (the resolver you specified in polymix-4.pg
file, probably 172.16.1.100) from 10.1.0.11 (ping -S 10.1.0.11
172.16.1.100). If that does not work, you probably need to fix your
routes.

Once you get routing working, the second step is to verify the DNS
server availability and configuration. The HOWTO section you read has
a "dig" command example that can be used for that. Make sure you run
"dig" on a client box.

If all of the above works, and you still get "timedout waiting for
DNServer" errors, we will need to find a more advanced way to debug
the problem. In either case, let me know if you get stuck.

Robots do not need DNS names. Your DNS server needs to resolve
Polygraph servers' addresses only.
