Well, that certainly doesn't look right.  You're configuring the 
interface to use send all packets destined for the subnet to itself, 
and also telling it that itself is the DNS server.  Of course it's 
going to go silent on you.  :-)

I suspect you should probably look at the GUI tools first, and only 
start manually configuring nodes if you have to.  One thing all of us 
aim for in cluster building is that you should never have to configure 
individual nodes by hand; it's doable for 10 or so machines, but is 
totally unfeasible in larger configurations (such as here, where we 
have a cluster of over 1000 nodes)
