SSH (Secure Shell) keys are a set of two pieces of information that you use to identify yourself and encrypt communication to and from a server. If you are having trouble logging in: please read the rest of this page and our Troubleshoot Login page, then contact us if you're still having issues. To use graphical programs on the clusters, please see our guides on Open OnDemand, X11 Forwarding and VNC. Once we have your public key you can connect with ssh node addresses and other details of the clusters, such as scheduler partitions and storage, can be found on the clusters page. Allow up to ten minutes for it to propagate. Send us your public SSH key with our SSH key uploader. Request an account (if you do not already have one).
For hostnames and more instructions see our Open OnDemand page. If you're just getting started or prefer a more graphical interface, Open OnDemand (OOD) is an excellent way to access the clusters. For off-campus access you need to use the Yale VPN. You must be on the campus network to access the clusters.
