The Internet I found when I first wandered into a housemate's Usenet account in 1985 or so at Michigan was structured so that email left campus three ways: MTS mainframe mail via MIT-MULTICS.ARPA in Massachusetts EECS Unix mail via ihnp4 in Illinois Physics mail via SPAN and thus cross-campus email from EECS to MTS required baroque and completely unreliable addressing. The on-campus postmaster duties that occupied most of my undergraduate career involved systematically simplifying on-campus email and making it more reliable, with the overriding goal to allow any department head to send email to any dean in the morning and have it received in time to schedule a lunch meeting. There was a lot of work to do, in part because on-campus email volumes only increased as more people got online, and because expectations moved from same day service to instant service. Here's some of the things we had to do. * The MTS mail system had a front end gateway, a Vax running BSD 4.2 connected to it over an X.29 line. I was the junior postmaster there making sure that the mail queues kept moving. Sendmail incorporated a bunch of changes to handle queue managment over that time, since intelligent handling of bounces, temporary network failures, and slow links made a huge difference in throughput. That system eventually got a direct TCP/IP connection which had a big impact. * Name servers had to get set up, loaded with current information, and debugged and bullet proofed to the point where the whole campus could rely on them. Hans-Werner Braun was responsible at the start of the umich.edu DNS setup, and I remember at least a few late nights where patches went in more promptly than you'd do now. * Various and sundry Unix systems around campus had resolver libraries patched in so that they could use the (then new) domain name system. The then-current SunOS shipped with name service through hosts.txt, so you had to fix each system that you wanted to turn up. * There was a considerable amount of UUCP going on around the area, both to support Usenet newsfeeds and to connect to sundry industrial affiliates (and hangers on). Maintaining the UUCP network was part of the professional training of systems administrators, making sure that they knew where to get their next job (at the other end of the email link). Noticably delayed on the Michigan campus was BITNET; that was eventually turned up near the end of the mainframe era there (1990?) after I had left campus. Someone needs to also mention the Morris Worm - 20th anniversary coming up soon! - which I witnessed first hand while doing tail -f /var/log/mail.log of the log files on the Vax from my Apollo Domain console late one night and seeing weird error messages. Fortunately most of the campus mail systems had enough patches applied that the precise infection vector didn't work. thanks Ed Edward.Vielmetti%UMICH-MTS.MAILNET () MIT-MULTICS ARPA uunet!umix!emv ------------------------------------------- Archives: https://www.listbox.com/member/archive/247/=now RSS Feed: https://www.listbox.com/member/archive/rss/247/ Powered by Listbox: http://www.listbox.com
