The SSH-Gateway is a service that allows ssh connections from off campus to on campus servers. This service also allows SCP/SFTP connections to your home directory on storage.rice.edu.
As a staff or faculty member you can use this service by connecting to ssh-staff.rice.edu with your favorite ssh client. When you connect you will not get a shell, instead you will be prompted for the host you want to connect. This connection will be made using the NetID you connected to ssh-staff.
When you connect using SCP or SFTP it will point to the root of your home directory on Storage.rice.edu. This connection is made using NFS.
