UUCP?

kragen 2y ago
mit-ai was running its, not unix, and there wasn't even a port of unix to the pdp-10 at the time. moreover uucp addresses are of the form host!user rather than user@host

  It was more of host_route!hop2!hop3!etc!user, You kept a list of routes on your terminal. Here is a very early map of the routers. https://groups.google.com/g/net.general/c/u1dxxNcTIX0/m/mHMWbCVJZswJ https://groups.google.com/g/net.general/c/u1dxxNcTIX0/m/mHMW...

    yeah, eventually, but in 01976 uucp was just getting started. even in 01978 i don't think they had a well-defined network map, though they said uucp already connected over 100 unix machines in the 7th edition manual. that post is from 01981 unfortunately 'show original message' is grayed out, so i can't actually see the map

  To clarify on account of kragen's idiosyncratic avoidance of uppercase, "its" is "ITS", the Incompatible Timesharing System, developed by MIT's AI Lab: <https://en.wikipedia.org/wiki/Incompatible_Timesharing_System https://en.wikipedia.org/wiki/Incompatible_Timesharing_Syste...>

    oops, sorry, thanks

UUCP was Unix only, and was only getting started around that time with more copies of Unix showing up outside of Bell Labs

  For anyone who might not know, UUCP literally stands for "UNIX-to-UNIX copy". Of course, especially given its relative simplicity, at some point non-UNIX systems started to implement it (I think I maybe used some DOS package at some point).

  Thank you. I wonder: is FTP that old? I kind of thought UUCP predated FTP. My parent mentioned email possibly being a special mode of FTP. _some poking around in Wikipedia_ Indeed, FTP is from 1971 and UUCP is from 1979. And the SMTP page describes that it all started as a mode in FTP.
  - p_l 2y ago
    SMTP evolved as replacement for older approaches which, at one point, involved using FTP to mangle mailboxes remotely. Not so much a special mode for FTP as essentially an "use of" FTP. Similar to how non-trivial amounts of Electronic Data Interchange in business happens over FTP(S) to this day.

  UUCP was definitely not "Unix only", several operating systems supported it back in the day, Lisp Machines and ITS could access UUCP over Chaosnet. Mark Plotnick wrote the service (aka deamon) for Chaosnet for Unix in 1984.

UUCP used /bang paths/ where you had to know (one of possibly several) routes to the recipient's system... http://catb.org/jargon/html/B/bang-path.html http://catb.org/jargon/html/B/bang-path.html

uucp would not be written until years later.
