For anyone who knows SuSE Enterprise, you can file this one under "what a n00b!" (my SuSE experience in the past has been with openSUSE), but I recently inherited a project that required RHEL or SuSE Enterprise so they chose to deploy SuSE Enterprise on EC2 to reduce acquisition time. (Who would've thought a cloud provider like Amazon would be faster to acquire an install of one of these softwares that used more traditional licensing models?) Anyway, I needed to install a few extra pieces of software, but when I ran yast, its list of repositories was empty!? Turns out the fix is really easy, but I couldn't easily find the answer within a minute or two, so I thought I'd share:
suse_register -a email="email@example.com"
Yup, that was it. No license key required (at least on the EC2 build). Novell just wanted my email address.
