To connect via SSH from off-campus you must do one of the following:
- setup a VPN connection, and then connect to the cluster directly. We recommend installing the GlobalProtect VPN client on your workstation or laptop. The installation procedure takes about 90 seconds. A VPN is also needed to use MyAdroit or MyDella.
- ssh to <YourNetID>@tigressgateway.princeton.edu and then ssh to the cluster. A VPN connection is not required for this approach. You must have an account on one of the large clusters to do this.
- ssh to a host on the wired on-campus network (e.g., nobel.princeton.edu), and then ssh to the cluster. A VPN connection is not required for this approach.
If you don't do one of the above then you may see an error message like Connection closed by remote host or Operation timed out. If you see Permission denied (publickey,keyboard-interactive) it means that you don't have an account (see this page).
To SSH to one of the HPC clusters you must either be on the campus wired network or connected to the eduroam wireless network. You cannot log in to any of the clusters while connected via the puvisitor wireless network, servicenet or a network specific to your research group.
