> From: Jason Stevens > it also appears that AOS was the router backbone of the NSFNet once > they started to migrate off of the IMPs Say what? IMPs were only every used in the ARPANET (and networks built by BBN for private clients using that technology). The first routers used in the NSFNET were things called Fuzzballs - PDP-11's running software from Dave Mills, driving 56KB lines. They eventually decided they needed to step up a level, and a consortium involving IBM won, with IBM RT PC's running AIX driving T1 lines. Noel

RT/PC-centric AIX history

by Charles H Sauer

I've refrained from jumping into AIX & RT/PC discussions on TUHS. It seems more appropriate to summarize AIX history than try to correct or clarify specifics out of context. I wrote about 5 pages, got feedback, revised accordingly, and posted at https://notes.technologists.com/notes/2017/03/08/lets-start-at-the-very-beg…. Charlie

Re: [TUHS] UUCP: working systems, come and get them

Neither have I! But yes, feel free. In yur SimH .ini file, put (or change) this line to say: attach dz line=0,Connect=simh.tuhs.org:5000 which will connect /dev/tty00 to simh.tuhs.org port 5000. Then set up your L.sys file with a line that says: seismo Any;9 DIR 9600 tty00 "" "" ogin:--ogin:--ogin: uucp ssword: uucp so that the uucp site seismo can be contacted via /dev/tty00. Then you can try doing: # echo hello there | mail seismo\!root <wait a few seconds> # /usr/lib/uucp/uucico -r1 -sseismo -x7 and you should see the debug information with parts of the uucp conversation.

OK, try this: Edit your /etc/remote file to say this for dialer: dialer:dv=/dev/tty00:br#9600: Now try: # tip dialer which should connect out over /dev/tty00 to seismo via the TCP connection. Hit Return a few times to see if there is any response. On your host system, do netstat -a | grep ESTAB and see if there is a TCP connection to simh.tuhs.org:5000. I also forgot. To be able to send e-mail, you need to add seismo to the list of known remote sites in /usr/lib/sendmail.cf: CWseismo Cheers, Warren

A computer at BBN was set up to regularly dial all the TIP modem lines, to check that they were working. One line was always down, so they listened in, and heard some human say "it's just that pevert with the whistle again". I wonder which one was the original: anyone know for sure? Noel

Re: [TUHS] Historical uucp maps?

by norman＠oclsc.org

Warning Toomey: In ASCII at http://www.redace.org/html/logical_usenet_map_1984.html === That's no UUCP map. It's a USENET map: a map of netnews propagation. No, they're not the same at all: many places that used UUCP to exchange mail didn't participate in netnews. In particular I see a site I used to run with none of its important mail links like ihnp4, and only a link to a system I don't remember at all. I had left that site a few weeks before that map was published, but I stayed in touch with the folks there; had all the mail links been torn down I'd have known. Had someone decided it was worth while dipping a toe into netnews, though (something I never bothered with) I might not. In fact I suspect it would be difficult to find believable maps for UUCP except amongst major forwarders. At its peak it was an extremely informal network, with lots of links that weren't published anywhere because people at site A wanted to keep in touch with those at sites B and C but didn't want to pay the bills to forward mail between B and C, let alone between those sites and places twelve time zones away.

Historical uucp maps?

by Warren Toomey

We are going to need some historical uucp maps so that we can construct our simulated uucp network which bears some resemblance to the past. There is a 1984 map on pages 7 to 14 of http://www.tuhs.org/Archive/Documentation/AUUGN/AUUGN-V05.4.pdf As Dave mentioned, we need some key sites like ihnp4, cbosgd etc. What other key sites? Any volunteers to run some of them? Warren

observations on Unix v6's mount command

by Mark Longridge

I was trying to look at mini-unix so I mounted the disk image inside unix v6 via: /etc/mount /dev/rk4 /usr/mini-unix and I noticed that if I ran the mount command as a user and not root that /etc/mtab would not be updated (but it was updated as expected as root). Of course /etc/mtab is owned by root :) Then I noticed something else when I did an ls in the /usr directory: drwxrwxrwx 20 31 368 Sep 3 1976 mini-unix Normally I would see things like: drwxrwxr-x 2 bin 48 May 13 1975 adm What does the 31 mean?
