Remote Access
This page provides an introduction to remotely logging into NOAA RDHPC systems (Gaea and GFDL PPAN).
All connections to the NOAA RDHPCS enclave are made via Secure Shell (SSH) in a terminal session to a bastion. For more details, users can refer to the NOAA RDHPCS connecting ppage. Below, we provide brief instructions on how to log in to NOAA Gaea and GFDL PPAN HPC systems.
Users who do not have a CAC, or who lack the required hardware or software, are welcome to use an RSA login. To log in to Gaea with trusted X11 forwarding, users can use the following command:
ssh -Y First.Last@gaea-rsa.princeton.rdhpcs.noaa.gov # loging using Princeton baston
or
ssh -Y First.Last@gaea-rsa.boulder.rdhpcs.noaa.gov # loging using Boulder baston
When prompted, enter your PASSCODE which consists of your PIN+RSA_CODE. The RSA_CODE is the 6-8 digit code from the RSA fob or RSA app.
After successful authentication at the bastion host, a list of available nodes will be displayed with a 5 second delay to choose a specific destination. To select a specific host, press Control+C (^C) and enter the desired node.
Here is an example of what the display looks like for current the Gaea system:
Keep in mind after the 5 second wait, the bastion node will use a load balancer to select a node.
Similar to Gaea, to log in to PPAN with trusted X11 forwarding, users can use the following command:
ssh -Y First.Last@analysis-rsa.princeton.rdhpcs.noaa.gov # loging using Princeton baston
or
ssh -Y First.Last@analysis-rsa.boulder.rdhpcs.noaa.gov # loging using Boulder baston
Again, when prompted, enter your PASSCODE which consists of your PIN+RSA_CODE. The RSA_CODE is the 6-8 digit code from the RSA fob or RSA app. You will then be able to select a specific node after a 5-second delay..
