I wish it really was that simple.
As I said, I tried eth-eu as that as the default. I will eth.us but I don't expect that to be any different.
Well then an even simpler question then... is your DNS working on that rig? Can you ssh into that rig and attempt to ping eth.au.dwarfpool.com? I think the user and password is "miner" (without quotes)
Can you use any other pools?
