GO FUND KLAUS.
PLEASE.
Knoppix was my first experience with Linux over 20 years ago; my brother-in-law introduced me to it and it was really neat. "My computer isn't just Windows!"
Now with major distros offering live sessions in their installer, you can just hop into Ubuntu/Fedora/Arch.
The most interesting thing was the patterns you could see with various teachers and pw reset policies. Some had themes like seasonal, others would take the current month and tack-on a number.
I ended up getting expelled for using that domain admin account to poke around. Had to transfer to a different school and was perma-banned from touching a computer for the rest of my time there. It ended up being a blessing in disguise, I had a lot more fun and grew up a lot at the other, larger high school. I still recall my guidance counselor helping me setup my classes for senior year... "ok, yeah and we'll put you in programming for your elective... OH WAIT... you aren't allowed to be anywhere near a computer, ceramics it is". Ceramics ended up being a blast!
I ended up scraping a whole bunch of credentials, even teacher creds, but they were always permissioned. Math teacher had a single folder where math stuff was dumped but couldn't escape that.
One day we were sitting in one of the computer labs, and written on the board was just:
U: training P: training
with no effort having been made to erase it.
That turned out to be effectively complete teacher level access. They couldn't decide what to do with a bunch of student teachers so just gave them unnamed creds with access to all subjects. And they left the account active for 12 months after the training program. By then, we had scavved up the credentials of a teacher who had been at the school since its inception, and thus had done every job and had the same sort of teacher god rights. His password was just redrocket or something silly.
I had exams, exam answers, notes on student performance, basically everything possible for 3 years. I am so glad there was no logging or anything sensible or I would have been expelled too.
