Requesting Access
In order to gain access to Rocky you must first fill out the Rocky_Access_Form.
Logging in to Rocky
Once your account is created you will be able to use SSH to gain shell access or SCP to copy files to/from Rocky.
Rocky uses Public Key Authentication for access instead of passwords. You should have generated a key pair and submitted your public key when filling out the Rocky_Access_Form. You will now need to use the private key when authenticating to Rocky.
Rocky's firewall limits access to the UTK network. You will either need to be on campus or using the Campus VPN

To use Lmod, you will use the module command. For example, to see what modules are available:

To load the R environment:
module load R
To load the Python environment:
