Subject: Re: Mutant01 IP = 205.138.39.180
I agree. I recommend putting up a link on a webpage like mine and then
updating it with an IP poster. My IP numbers change *very* rarely but it is
a good idea to still use a link on a webpage that is updated by an IP
poster. I still recommend using a Windows box for the job, a cheap 75Mhz
Pentium with Windows 95 will easily handle 7 TELNET connections at 9600
baud. I am moving mine over to a new Celeron box tomorrow morning for
dedicated 24/7 connections to my PDP-8/11s
http://www.pdp8.com/1135.htm
Anyone here have any vintage software to run on a PDP-11 as a front end
connection server? Waterloo University used a PDP-11/45 back in the '70s in
front of their *huge* cluster of some 3-500 DEC minicomputers. I've got
heaps of DZ,DL,etc.. from the warehouse so serial ports are not a problem.
Expect the first version of DOS/BATCH-11 next week.
No electricity costs here ;-)

While the effort is noble, I suspect the repeated
"my IP address
changed" messages will grow old quickly. Perhaps the changes could be
posted somewhere such that interested parties can obtain the
information over the web, or with finger?
I agree... the updates *have* grown old already... they are
a waste of bandwidth... I tried one of them and got to an
OS/2 system... I'm not sure if it counts yet as classic... it
surely is not as interesting as an RT/RSTS/RSX/TOPS10/ITS system
might be...
The DG hardware may be more interesting... but I'm not famliar
enough with them to know what to do with it...
Either way, I agree that it would probably be more useful to put
the info up on a web page somewhere, send us all one (1) pointer
to it... and those who are interested will bookmark it to check
what the address is...
Just my $.02

RPI did the same kind of thing on their mainframes (3033, 3081D, 3090,

called simply the FEP (front end processor), it was dependent on the host
system for help with scrollback buffers etc., so if the mainframe went down
so did the FEP. Then later they switched to a bunch of 11/73s called NIMs
(network interface machine), running software developed at UBC (in the
PLUS programming language, for which a PDP-11 cross-compiler existed on the
mainframe). They had lots of their own memory and were independent from the
mainframe, essentially they were big fat terminal servers. IIRC they spoke
X.25 to the mainframe (with the "VTP" virtual terminal protocol running on
top of that, or optionally X.29 (??)), but they also could do TCP/IP for
talking to everyone else.
But I don't understand what the goal is here. Just a reverse terminal server
to hook up to a bunch of non-TCP/IP-aware PDPs using serial lines? I don't
know of anything like that, although it shouldn't be *that* hard to write.
I've never played with the MINITS system but AFAIK it's just some kind of
TAC system, maybe it could be turned around backwards and adapted for this?
Anyway last time I put a non-TCP/IP-aware PDP-11 compatible system on the
net I just used a Linux box with a version of telnetd hacked to use serial
ports instead of PTYs, it's cheating but it was very fast and at least it
spoke "modern" TCP/IP.

Cambridge Universtiy (UK) did something similar as a frontend to their
IBM 3084 mainframe.

That is how I have been browsing the web from the Dasher 214 terminal
upstairs is by Telneting into my warp or linux boxand running Lynx from
there. There is also a cool Sun box on the internet you can telnet to and
have a full shell account. That is useful as hell and eliminates the
linux or warp 'lynx proxy' job from my intranet. You can even run stuff
like slurp and they don't mind as long as you don't leave such processes
running while you are not logged on. It just Feels a little closer to
running the client locally ;-)
As for 'modern' tcp/ip, I am running into troubles with DNS and Sendmail.
I can Ping a hostname on my intranet via :etc:hosts but Nslookup says
'host unknown'. Someone said it had to do with the IQUERY setting in DNS.
Do I really have to run my own DNS for sendmail and such to work when the
Data General can already ping, telnet, and ftp by hostname through the
router? BTW, the version of Sendmail I am working with is the one
provided in Data General TCP/IP v1.40 and it's version is v1.00. Yea. I
am looking for a C compiler and libraries....
Are you guys just cracking on me by keeping my former IP address as the
topic of this thread or what? I do intend to create a link but have not
gotten around to it. As it is, that address has a lot of press on this
system even if it isn't valid anymore.<grin>

New subject: Shell System
Telnet to NETHER.NET. I can't believe I omitted it from my message. Geez.
You will go through some tutorial stuff for newbies then create an
account. You can then log in as yourself and get a shell of your choice.
