These nodes are actually going into '/var/beowulf/unknown_addresses'.

These are moved into '/etc/beowulf/config' via the 'beosetup' tool
or manually. (see comments in this file for details...)

Beyond that, the only suggestion I can make is that you might want
to have the frontend before your IP range instead of after. This
may make it slightly less traumatic to expand the size of your cluster
later.

Run 'beosetup'. We don't presume -- entirely automatically -- that
you want a given box in your cluster. The beosetup tool can be 
configured to automatically add new nodes.
