Process accounting - did anyone ever use it?

re: the last paragraph about "Cliff Stole" (actually Clifford Stoll) and accounting discrepancies: https://alumni.berkeley.edu/california-magazine/spring-2016-war-stories/how… ?It was a 75-cent accounting error in the computer usage accounts,? says Stoll, who looked?and still looks?like he stepped straight off the pages of The Fabulous Furry Freak Brothers. ?I traced the error to an unauthorized user who had used about nine seconds and not paid for it.? Stoll assumed the trespasser was a Cal undergraduate doing it on a lark, ?just some kid on campus who was yanking my chain.? Fascinated by the challenge of identifying the intruder, he spent the next ten months trying to solve the puzzle, often sleeping on a cot at the lab instead of going home, because whoever it was tended to log on late at night. ?It was like a piece of yarn dangling from a sweater,? he says. ?You keep pulling on it and discovering that the yarn never ends. The sweater keeps unraveling until all you end up with is a mountain of tangles.? On Thu, May 30, 2019 at 9:55 PM bobh--- via cctalk <cctalk at classiccmp.org> wrote:
