Some years ago, I read a post on HN where someone made a text-mode game(? or something similar?) available through SSH. People could play the game by opening an SSH session and play from their terminals. This was non-trivial, and they explained all the ways they configured sshd to prevent players from running binaries other than the game.

I didn't bookmark that post, and I haven't been able to find it again to my great dismay. If anyone remembers this post and still has it, I'd love to read it again.

It's not that, but still very cool!

None of the links here seem to be the one post that I found years ago, but this one in particular is pretty interesting.

I found this[1] one while looking around, the thread has some additional interesting remarks, including an LD_PRELOAD attack vector.
