Running SSH on 1st Revision AppleTVs
Sometimes it can be really useful to have an SSH connection into your AppleTV. If I need to explain why then you probably won’t want to do it. Unless of course, you’re just after getting something like Boxee running, which we’ll look at as well. Before we get into doing anything to your AppleTV, when we’re done I do not know how Apple will feel about your warranty moving forward, so do this stuff at your own risk (but that’s pretty much true for many articles on this site)… So first up, let’s install SSH. To get started, plug in a jump drive you don’t mind reformatting. Then run the…
