I would highly recommend to everyone not to buy one single bitcoin miner from Lketc.com
We are in the process of setting up 100 machines we just bought from them, i have spent the last 2 weeks while waiting for their ridiculous slow shipping to recieve the miners, in that time i built a management interface to easily manage all miners from a web UI.
This management system needs to use ssh as part of the control mechnaism, using a dragon miner i had a few months i based the system on that, we just setup the farm and in process of setting up the machines but we can not ssh into the raspberry pis
the default ssh password should be
user:pi@host
password:raspberry
they have now changed this and there skype support guy said they will not tell it to me because its a secret. I think this is disgraceful i own this computer outright therefore should have full root access to the system.
i do not want some slinty eyed chinese person having full ssh control over my farm and £100sK pounds worth of equipment.
Luckily i have an old ISO which has the old SSH setting but it is incredibly time consuming to burn 100 new iso.
I would not trust this company at all who will not give you root access to the server or to see what is hidden on the OS.
AVOID THIS COMPANY UNTILL THEY SORT THIS OUT
