Access Prerequisites
Follow this table to determine what is needed to access classified (SCF), unclassified Collaboration Zone (OCF-CZ) and unclassified Restricted Zone (OCF-RZ) Livermore Computing (LC) systems.
Available Resources
LC provides unclassified Open Computing Facility (OCF) and classified Secure Computing Facility (SCF) high performance computing (HPC) resources.
OTP (One-Time Passwords, a.k.a. Tokens) for CZ, RZ, and SCF
OCF and SCF users (except for LANL and Sandia on the SCF) authenticate using a PIN and an LLNL RSA token/one-time password (OTP). Additionally, OCF RZ users require a PIN and a RZ RSA token passcode. The LC Hotline will send you an LLNL RSA token and/or RZ RSA token when you are given an account.
SSH and VPN Access
Secure Shell (SSH), is the only login method for LC systems. SSH includes SCP or SFTP for file transfers between hosts. For more information on SSH and SCP, SSH access modes, RSA/DSA authentication, and how-tos, see the Secure Shell section of the Introduction to Livermore Computing Resources.
Logging in to LLNL Machines
Login methods vary, depending upon where you are coming from and where you want to go.
File Transfers
Files may be transferred using Hopper, SCP, FTP, SFTP, NFT, HSI, or HTAR . For more details, see the File Transfer and Sharing section of Introduction to Livermore Computing Resources.
Miscellaneous Access Topics
X Terminal Control For an X client (such as the TotalView debugger) to display on an X-display server (such as your X terminal or workstation), the client must be authorized to connect to the server. XAUTH offers an alternative way to manage this authorization.
