How to use your SSH key pair to log into another remote machine.
The Department of Energy (DOE) mandates that all DOE facilities use two-factor authentication methods on all gateways into the facility that provides shell access. The SDCC gateways support SSH key login.
See our gateway information page for a list of gateways and complete details.
Information on the Ssh Gateways at the RACF
The SSH gateways at the SDCC are the primary interactive "doors" into the SDCC facility. They should only be used to gain interactive access to the facility, they are NOT designed for data transfers (aka SCP access). Once you have logged into an Ssh gateway, you can hop to the internal system of your choosing via ssh. The old RHIC & USATLAS SSH gateways have been deprecated and consolidated to the single set of SDCC SSH gateways.

How to generate SSH key pairs
SSH keys are generated using the
ssh-keygen program on Linux/Unix/ MacOS/Cygwin, or with PuTTYgen on Windows. For Windows users please go here
Please ensure that the 'Number of bits in a generated key' is 2048 or larger or your key will be rejected.
