Direct SSH Gateway Access to Peregrine

Directly access Peregrine from your office, lab, or home.

Many tightly-secured facilities do not allow outside VPN software or connections to external VPNs. The login node allows direct SSH access to Peregrine for users outside of NREL. The SSH Gateway (, does not provide direct access, making some processes more challenging.

Logging into

When you connect, you will be prompted for Password+OTP_Token


If your password is perfectNorth-Nov11 
and the token reads 123456 
you would type: perfectNorth-Nov11123456

8-hour Session Limits and Maintenance

This system is patched regularly and connection interruptions may occur. Additionally, there is an 8-hour connection time limit. We recommend taking advantage of tools such as tmux and screen for session management that will accommodate the ephemeral nature of Internet connected sessions.
