Activating Red Hat Enterprise Linux


In this article:

The university has a Red Hat Site Subscription entitling all students, faculty, staff, and departments to use most Red Hat software, including Red Hat Enterprise Linux (RHEL). The Division of IT offers RHEL ISOs through TERPware and they can be activated by following the instructions on this page.

Getting an activation key

  1. Log in to the Special Identity Management System (SIMS) using your Directory ID and password.
  2. From the Request New Identity section, click the System drop-down box and select redhat.



  3. Give your activation key a name and description.
    • These fields are only used in the SIMS interface so that if you have multiple keys, like a personal key and a department key, you can tell them apart.
    • You can also provide a list of other people who are responsible for the key in the Administrators field. They will have the ability to renew the key and can take ownership of it if you leave the university.
  4. After submitting the request, SIMS will show you the activation key.
    1. This is the only time it will be displayed, so take note of it. If you lose it, you can submit a reset password request for the key on the SIMS home page and it will give you a new activation key.
