Add or Manage SSH Keys

In order to be able to log into the started VMs, among other purposes, you need to provide a Secure Shell (SSH) public key. If you are already a frequent user of SSH, and have a private and public key pair, it is perfectly reasonable to provide your public key. It’s public, after all. We do require that a minimum 2048-bit key is used. This is the default on most up-to-date systems but if your key pair is older it might be less. If it is, you will need to generate a new key pair for use with FutureSystems.

To upload the chosen public key:

  1. Copy the text of your public key into your system clipboard.
    • This text starts with something like "ssh-rsa AAAAB3N..."
  2. Visit the MY ACCOUNT link at the bottom of the portal website.
  3. Once on your account page, click the Edit tab link.
  4. Paste the text of your public key into the SSH Public Key field at the bottom of the page.
    • To add a new key, use the blank field.
    • To replace a key, paste in the text of the new key in its place.
    • To delete a key, select the entire text value and delete it.
    • Be sure there are no extra line breaks, leading or trailing spaces, blank lines, etc. in the key text.
  5. Click the Save button at the bottom of the page.

If you are not familiar with SSH keys, see IU's Knowledge Base article "Set up SSH public-key authentication to connect to a remote system."

Changes to keys will take up to 1 hour to propagate through the system services. You are not allowed to use passwordless keys. Your account may be deactivated if you violate this policy.
