The IST SSH Gateway supports remote access to Linux and Macintosh systems on the wired IST network that have ssh/remote access configured.

System Requirements

• An appropriate SSH client for the operating system you're working on. Putty works well for Windows, the Terminal app in OS X is fully featured, or the SSH client appropriate to your shell on a Linux system are the suggested, best-supported clients.

• SSH remote access configured on the Linux or Macintosh system you're trying to connect to.

• As of December 1, 2020, an active VPN connection is required to SSH or SFTP to any Penn State system.

How to Connect

• The address to connect is ssh.ist.psu.edu.

• The port is 22.

• Access is available from any Internet address/network.

• The credentials you must log in with are your Penn State username and password.

How to Transfer Files

• SFTP and SCP are supported methods for transferring files to ssh.ist.psu.edu.

• SCP is the suggested method for transferring files from ssh.ist.psu.edu to your data's final destination(s).

• Clients such as FileZilla (Mac/Linux) or Putty SCP (Windows) should work for connection.

Additional Information

• Typing in your password incorrectly three times will result in a 1 hour ban. The error you will receive is "connection refused". Once the hour passes, you will be able to try logging in again. If you're unsure of your password, please contact the IST Helpdesk.

• Concurrent logins are limited to 2. The intent of this service is for you to connect back to a desktop or server, then manage your additional connections from there with tmux, screen, or an equivalent package that maintains your sessions.

• Full graphical access (X11) on ssh.ist.psu.edu is not supported.

• Maintenance on home directories is run weekly on Friday mornings. Any data, including stored ssh keys, saved locally in your home directory is subject to deletion. Your data is not backed up.
