Okay, the two machines are on tow different networks, but i know the spreads
can talk, because i'm using spread for something else with these machines
and it's fine. I can see them both belonging to the wack1 group in the
spuser tool. The maturity setting is the default in the sample config. The
config has prefer none. I'll try it again and let it run longer....

Are the two IP addresses wackamole is responsible for on the same
subnet.

That is what most people do. It works very well as long as there
is no preferred IP.

sounds like the two wackamoles cannot talk to each other. Check
your spread config. You can have config options to see group
information and whether or not the two managed to join the same group.

That is unlikely except is maturity is very low(wackamole config).

Use a wackamole.conf with one virtual IP and no preferred IP.
