SunOS 4 definitely had YP. We used it in school when the Tops-20
machine was replaced by a boatload of 68000 machines running SunOS and
Suntools... I can't recall if 3.5 also had it or not... it was later
it changed to NIS.
Anything that had Sun's NFS had YP, at least as of version 2.0. It was
part of the package.
Somewhere in Warren's archive is a source copy of NFS 2.0 from Sun that
I donated. It's replete with all the YP stuff. Not sure if the following
is the copy I donated, but it's close enough:
https://minnie.tuhs.org//cgi-bin/utree.pl?file=NFSv2/usr/src/usr.bin/ypcat.c
From my copy:
-r--r--r-- 1 krewat kilonet 6356 Nov 20 1985
./usr/src/usr.bin/ypcat.c
Interesting that the date is one day off.
The copy of NFS 2.0 that I donated was integrated with BSD 4.2 at
Computer Graphics Lab at New York Institute of Technology. When they
went kaput, I managed to get my hands on that NFS tape along with a slew
of other stuff that I can't do anything with because it's all copywrited.
/etc/nsswitch.conf in Solaris originated with NIS+ (NISPLUS). Sun seems
to be the origin, and it only came about because of NIS+. That's my
theory and I'm sticking with it ;)
