Logging into a NetBSD VAX session and then being logged out

[Gregg Levine <gregg.drwho8%gmail.com@localhost>]

Hello!
In the book "Cuckoo's Egg" Cliff Stoll describes the guest account on
the UCB VAX systems. And further he describes that the login function
would allow someone do so via the login of guest and password of guest
and that the account would be timed to run for a minute. Now as I
recall he wasn't sure how much someone could do within a minute of
system time, where they cost (then) about $300 per hour, (which of
course if someone presses me on that I'll have to look it up). And
naturally the school figured it would be good publicity.

Now that was on 4.2 (or 4.3, or 4.1) BSD on the VAX and a good twenty
or more years later of course.

Now my question, how could a running system be so configured?

Suffice to say it would be running on SIMH simulating a VAX, and on a
Pi2. My next big problem would be what to do next after that, but the
big sticking point is getting the simulation to do that.
