I got a fancy HPUX refrigerator-sized server to replace a mainframe in the early 90's. Was on Netware 3.11 at the time and did not understand the concept of IP, so just made up a bunch of random IP addresses. The confusing thing was telnet did not work at all, but ftp kinda/sorta did. That was an embarrassing call with HP support, but the guy I talked to kindly gave me a 30-minute tutorial and usenet filled in the rest later (and crynwr packet drivers).
