Thanks, I followed the instruction above, for the first miner I put my regular steem account (as I couldn't figure from the instructions if I was to do this but thought from other mining stuff I read it should be in there), and I put variations on the next four in alphabetic declension. But I haven't had any way of putting in a private key. 
And how do I find the private key on the accounts that were created by the miner program? 
Miner seemed to be running, but it hasn't budged from 96% for quite a while, I'll leave it overnight to see if anything happens. (running vmware ubuntu server 16, 8 core, 5 miners, gaming laptop)
I rebooted twice and it has frozen for the third time at 96.0232%, will leave it be for some hours.
Apologies if I sound a bit ignorant of these matters, I'm good at following directions but this setup seems to imply one already knows more than is said. Any useful info greatly appreciated!
BTW, setup was a breeze, thanks for your efforts.
