Logging In

Logging in to LLNL Machines

Login methods vary, depending upon where you are coming from and where you want to go.

CZ systems | RZ systems | CZ web access | RZ web access | SCF systems | SCF web access

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 (CZ) 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 LANL start from ihpc-gate1.lanl.gov; at Sandia start from ihpc.sandia.gov. 

Make sure you have a valid kerberos credential - use the klist -l command. 

If in doubt, get a forwardable kerberos credential by authenticating with the kinit -f command. 

Then connect to an LC cluster in the CZ zone using your LC username: 

ssh -l lc-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 -l lc-username loginmachine.llnl.gov
User ID: LC Username
Password: LLNL PIN + LLNL RSA token

LLNL OCF (Unclassified) Restricted Zone (RZ) Systems

From Inside LLNL


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 LANL start from ihpc-gate1.lanl.gov; at Sandia start from ihpc.sandia.gov

Connect directly to the RZ login machine using your LC username and RZ credentials:

ssh -l lc_username loginmachine.llnl.gov

Password: PIN + RZ RSA token

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

NOTE If unfamiliar with how to VPN, see: https://access.llnl.gov/vpn/


ssh -l lc-username loginmachine.llnl.gov
Password: RZ PIN + RZ RSA token

LC.llnl.gov Web / Atlassian Access

From Inside LLNL

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

From LANL/Sandia

LANL users: authenticate with your

lanl-username@lanl.gov

and your LANL Kerberos password.

Sandia users: authenticate with your

sandia-username@dce.sandia.gov

and your Sandia kerberos password.

From Outside LLNL

Browse to lc.llnl.gov, you'll need to log in to a "pre-login" page first, and then the LC login page itself. Both use your LC Username + LLNL RSA token.

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

 

RZLC.llnl.gov Web / Atlassian Access

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

Begin on a LANL/Sandia iHPC login node. For example, at LANL start from ihpc-gate1.lanl.gov; at Sandia start from ihpc.sandia.gov

Recommended: start your web browser (Firefox) on the iHPC node for better performance.  If you start a browser on an LC RZ machine, the X11 display coming back to LANL/Sandia is slower.

Access the RZ web page of interest, such as:
rzlc.llnl.gov
rzlc.llnl.gov/confluence
rzlc.llnl.gov/bitbucket
rzmylc.llnl.gov

When prompted for authentication use your LC username and RZ RSA pin + token

From Outside LLNL

Start VPN 

NOTE if unfamiliar with how to VPN, see: https://access.llnl.gov/vpn/

After VPN has been initiated, login to RZ.llnl.gov:

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

Connect to local, classified HPC system

Then ssh to an LC cluster using your LC username:

ssh -l lc-username loginmachine.llnl.gov
No password required

 

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

  or
Static SCF password

SCF Web / Atlassian Access

From Inside LLNL

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

From LANL/Sandia

LANL users: authenticate with your

lanl-username@lanl.gov

and your LANL secure cryptocard password.


Sandia users: authenticate with your

sandia-username@dce.sandia.gov

and your Sandia secure cryptocard password.

From Outside LLNL

Browse to lc.llnl.gov, you'll need to log in to a "pre-login" page first, and then the LC login page itself. Both use your LC Username + LLNL RSA token.

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

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.
