Specifically I'm thinking about things like the Newcastle Con= nection, etc.

I imagine that PDP-11's connecte= d to the ARPAnet running Unix would (e.g., RFC 681 style) would have adapte= d the HOSTS.TXT format somehow. What about CHAOS? Newcastle? Datakit?

What was the introduction of DNS into the mix like? I c= an imagine that that changed all sorts of assumptions about failure modes a= nd the like.

NIS and playing around with Hesiod ar= e probably the earliest such things I ever saw, but I know there must have = been prior art.

Supposedly field 5 from /etc/passw= d is the GECOS username for remote job entry (or printing)? How did that wo= rk?

Dan - all good question= s, but I think you are mixing a few things (which is easy to do as they all= had different evolutionary paths).

  • ARPAnet wa= s Rand, UCLA and UofI in the early to mid 70s.
  • UCLA line would = fork competely with the original Locus work of the mid 70's, which woul= d reappear later in the 80's post BSD
  • IP Networking was don= e by BBN for 4.1BSD in the late 70s - originally as an OS independant stack= (hence it has its own memory manager to insulated it from the local S).=C2= =A0 Besides UNIX I think it went into HP's MPE and maybe a couple f oth= er systems.
  • The BBN IP stack was then repliced into UNIX by UCB= /CRSG as 4.1A with Joy's sockets layer in 82/83
  • HOST.TXT wa= s finaly abandoned and BIND was then done (primarily at UCB by peed on by m= any) - I want to say eary 80's=C2=A0 the SCCS files might give you some= hints.
  • Hesiod was MIT/Athenia and NIS by Sun were=C2=A0 later deve= loped somewhat in the same time frame=C2=A0 =C2=A0(mid to late 80s)
    • CHAOS was completely seperate, although influenced the BBN code and was th= e early/mid 70s.
  • BTL's DataKit of course, had the UoI (Chesson)= influence was late 70s.
  • Best I can tell Newcastle was complete sep= erate from all of this (also late 70s).
