This page shows frequently asked question from administrators of OpenGENI racks and is part of the GENI Rack Administration pages.

User Administration

Q. I am the administrator. What can I access in my rack?

  • Local Administrator: Each OpenGENI rack is initially configured to allow ssh access for one administrator account to all rack devices. If you are this person, than you have access to the control node, compute nodes, and switches in the rack.
  • Additional administrative accounts: Any existing administrative account can be used to create additional administrative accounts. Procedure to create more Administrative accounts detailed in the OpenGENI Rack Administration instructions.

Q. I tried logging into the boss node with my administrative ID and got a "permission denied" error. What is wrong?

Access to the hosts and devices in the OpenGENI rack requires SSH public keys. Your SSH public key must be installed in the authorized_keys file to access the control and compute nodes.

If you want access the rack switches, you must first login to the control node and then ssh to the switches as detailed in your rack control plane details table. For example here is the Clemson rack details for the switches.
