Logging In

Logging in to LLNL Machines

Login methods vary, depending upon where you are coming from and where you want to go. The instructions below assume that the Access Prerequisites have been met. All access requires SSH (version 2) as described in Using SSH to Access LC Machines.

Accessing the Collaboration and Restricted Zones offers tips for accessing the CZ and RZ from your desktop or from an LC CZ/RZ machine.

LLNL OCF (Unclassified) Collaboration Zone Systems

From Inside LLNL

ssh loginmachine
User ID: LC Username
Password: LLNL PIN + LLNL RSA Token

From LANL/Sandia Begin on a LANL/Sandia iHPC login node. For example, at Sandia start from ihpc.sandia.gov; at LANL start from ihpc-gate1.lanl.gov.
If not beginning on an iHPC node, then follow the instructions below for "From Outside LLNL".
ssh -l llnl-username loginmachine.llnl.gov
No password required
Note: If you experience session time-outs due to inactivity, try adding the following two options to your SSH command:
   -o ServerAliveInterval=60 -o ServerAliveCountMax=30
From Outside LLNL ssh loginmachine.llnl.gov   or   ssh -l llnl-username loginmachine.llnl.gov
User ID: LLNL userid
Password: LLNL PIN + LLNL RSA token

LLNL OCF (Unclassified) Restricted Zone Systems

From Inside LLNL ssh rzgw
User ID: LC Username
Password: RZ PIN + RZ RSA Token

ssh loginmachine
User ID: LC Username
Password: PIN + RZ RSA token

 
From LANL/Sandia

Begin on a LANL/Sandia iHPC login node. For example, at Sandia start from ihpc.sandia.gov; at LANL start from ihpc-gate1.lanl.gov.
If not beginning on an iHPC node, then follow the instructions below for "From Outside LLNL".
ssh -l llnl-username rzgw.llnl.gov
Password: PIN + RZ RSA token

On rzgw:

kinit sandia-username@dce.sandia.gov

or

kinit lanl-username@lanl.gov

Enter Sandia/LANL kerberos password
ssh loginmachine
No password required
Note: If you experience session time-outs due to inactivity, try adding the following two options to your SSH command:
   -o ServerAliveInterval=60 -o ServerAliveCountMax=30

From Outside LLNL Start VPN
ssh -l lc-username rzgw.llnl.gov
Password: LLNL PIN + LLNL RSA token

ssh loginmachine
User ID: LC Username
Password: RZ PIN + RZ RSA token

LC.llnl.gov Web Access

From Inside LLNL

User ID: LC Username
Password: LLNL PIN + LLNL RSA token

From LANL/Sandia

Sandia users: authenticate with your

sandia-username@dce.sandia.gov

and your Sandia kerberos password.

LANL users: authenticate with your

lanl-username@lanl.gov

and your LANL Kerberos password.

From Outside LLNL

Start VPN
User ID: LC Username
Password: PIN + LLNL RSA token

RZLC.llnl.gov Web Access

From Inside LLNL User ID: LC Username
Password: PIN + RZ RSA token
From LANL/Sandia

Sandia users: authenticate with your

sandia-username@dce.sandia.gov

and your Sandia kerberos password.

LANL users: authenticate with your

lanl-username@lanl.gov

and your LANL Kerberos password.

From Outside LLNL Start VPN
User ID: LC Username
Password: RZ PIN + RZ RSA token

LLNL SCF (Classified) Systems

From Inside LLNL ssh loginmachine
User ID: LC Username
Password: SCF PIN + LLNL RSA token
From LANL/Sandia

1. Connect to local HPC system (LANL: must use LANL gateway: ssh red-wtrw)
2. Authenticate locally with credential forwarding (kinit -f) using your LANL/Sandia password
3. ssh -l llnl-username loginmachine.llnl.gov
NOTE: No password required

Other DOE Sites ssh loginmachine.llnl.gov
User ID: LC Username
Password: SCF PIN + LLNL RSA token

  or
Static SCF password

Login Nodes

Whenever you log in to an LC system, you are placed onto a login node. These nodes are dedicated to serving interactive activities such as file editing, launching batch jobs, compiling, file transfer, debugging, and other short duration activities. At any one time, there may be multiple users on a login node.

These nodes should not be used to run parallel and/or production jobs! By doing so, you may seriously degrade the performance of others' interactive work. Be sure to use nodes designated for interactive or batch production work to run jobs.

For more information about the differences between login nodes and nodes designated for production work, please see the Login Nodes section of the "Introduction to Livermore Computing Resources" tutorial and the Running Jobs page on this HPC site.

Logging Into LANL/Sandia Machines

Classified systems: both LANL and Sandia classified Tri-lab systems support Kerberos passwordless SSH access from LLNL.
Unclassified systems: access methods vary between Sandia and LANL.
Please consult the Sandia Access Instructions or the LANL Access Instructions for details.
