Overview
UW ARCC has changed the way you authenticate to HPC. HPC resources are now accessible using a public/private ssh key combination and certain HPC resources (including MedicineBow HPC) are only accessible through SSH with your SSH key and certificate. This makes it possible for you to authenticate on our HPCs without always needing to enter your password and approving two-factor authentication.
General instructions for all OS’s and Clients
To set up access:
First, log into the OnDemand resource for the HPC you want to set up SSH keys for.
For MedicineBow, log in at https://medicinebow.arcc.uwyo.edu/. Step-by-step directions for logging into MedicineBow OnDemand are available here.
For WildIris, log in at https://https://wiodm01.arcc.uwyo.edu/. Step-by-step directions for logging into WildIris OnDemand are available here.
Once you’re logged in, you should be presented with the HPC Dashboard. Click the following icon to set up SSH key authentication:
If you haven’t set up an SSH key previously, you should see an empty screen/list with the option to generate a new a key. Click that button.
Doing this will create a new set of files associated with your login to the HPC. Click download to download them to your client/computer.
Please be careful with these files. Do not change their permissions, put them in an insecure digital location, or share them with others. They are your “virtual keys” to log in as yourself on the HPC. If provided to or shared with others, they will be able to log into that ARCC HPC resource as you
The following steps should be performed on the machine from which you typically SSH into HPC. Further directions for configuration then depend on your preferred SSH client from that machine.
Directions for Windows, MacOS, an Linux are available below. Expand the section associated with the operating system on your local computer from which you plan to ssh into the cluster.
