Schneier on Security

This book was more for “sysadmins” – using a term from these years. For many users these years meant learning Unix commands for the first time. (It’s so much better than MS-Dos, of course.) Students needed to give commands through a terminal emulator to a system prompt running on a Unix machine – an internet shell account.

I remember a student help desk staffed by other students. They had a copy of Unix for Dummies and a large wall poster with a table that indicated what Unix variant was compatible with what other Unix variants – AIX, HP-UX, A/UX, etc.
