This will enable our system to transfer your SSH key onto the default user automatically, allowing you to log in as root.
IPMI Access

You can access an IPMI interface like the example below:

Then enter the username and password provided in the email you received from the dashboard, and now you can manage the system on your and will even be able to add your own public keys in the event of a reinstall of the machine.
If you have any issues with any of the IPMI interfaces please email lfedge-lab@iol.unh.edu and we will assist you in any way we can.
