Remote Access to Jefferson Lab Computing Resources

The Jefferson Lab network is segmented into enclave to limit access to and from the computing systems and services they contain.  Remote access to each enclave is limited and controlled through centrally managed remote access services and gateways in accordance with the site Cyber Security Program Plan (CSPP).

In addition to enabling remote access to users, the Computing and Networking Infrastructure (CNI) group provides several services for our users to use while off site.  The links to these services can be found at the end of this webpage.  We also offer several web utilities, such as e-mail and password change, that can be found under WEB UTILITIES on the right hand side of the webpage.  Please read the section below for details on remote access to the Jefferson Lab Common User Environment (JLab-CUE).

Remote Access to JLab-CUE

The JLab-CUE can be accessed remotely from off-site, and for guests on-site, using ssh protocol.  All off-site or on-site guest connections should start with a connection to login.jlab.org.  The use of multi-factor authentication (MFA) is required for remote access to certain enclaves or services.  This includes, but is not limited to, networks associated with the accelerator, LERF, experimental halls or business systems.

Windows Users

Please visit the Windows Remote Desktop Using PuTTY webpage for details on connecting.  As a Windows user, you must use PuTTY to establish an ssh connection to login.jlab.org.  Once you've established your ssh connection, please see the table below for system names of the operating system (OS) you wish to access.

Macintosh Users

For details on connecting to JLab from your personal Mac, please visit the Mac Remote Desktop webpage.  These instructions explain how establish a remote X session to the Windows terminal server cluster or a Windows desktop.

Linux Users

While we do manage a Windows terminal server cluster, our public Linux systems do not provide a Remote Desktop interface.  You may establish a command-line interface to our public systems using ssh.  Please see the table below for system names.
