Struggling to get initial foothold but slowly getting there. I think I’ve found two different places I can run stuff to try and get a shell, but I guess I need to find out how to run stuff (probably depending on specific conditions), and especially how to make it run only once (or better, on demand, just in case).
Gotta read more of the docs, that time period thingy isn’t getting me anywhere !
Cool box 
edit : just thinking aloud, really ; hope this doesn’t spoil too much !
