Logging in with administrative privilege
- SSH to cerberus[13-24].ncsa.illinois.edu and log in with your two-factor credentials.
- SSH to lsst-bastion01 and log in with your Kerberos credentials (necessary because you just crossed an adminstrative domain)
- SSH to any of the PDAC systems (no credentials required), omitting the "lsst-" prefix (in order to use the management network). You are now within the cluster and can move between pre-staging service nodes without credentials
- Escalate to root: sudo su - (or similar)
