[HECnet] Web-server under RSX-11M-PLUS

[Johnny Billquist]

By the way, a friend of mine once started on a TCP/IP for RSTS/E.
It is not complete, but I think he did get IP and UDP working. I have the code somewhere, if you would be interested...

Some parts possibly, but it would be very complex. Much of the actual
TCP/IP implementation is in the form of device drivers.

In RSX, there is (now) IF:, which is the basic device interfaces, IP:,
which talks raw IP (and ICMP), UD:, which talks UDP, and TC:, which
talks TCP.

The TC: driver, as well as the UD: driver internally then talks to the
IP: driver. The IP: driver in turn talks to the appropriate IF: driver,
depending on the routing tables.

TC: even understands file specifications, so you can do things like:

PIP TI:=TC:"130.238.19.212";17, which will give you the quote of the day
on your terminal (that's what port 17 is). (Try it on MIM:: :-) )

Device drivers are very different in the different OSes, so the basic
code that deals with the protocol bits can pretty much be used straight
off, but all the code dealing with the interfacing to the OS, memory,
other drivers, and user applications, will be totally different. I'm not
sure exactly how a device driver in RSTS/E works.

Also, for ethernet, I make use of a feature in RSX called an ACP, which
is like a user level program that extends the functionality of a device.
So the ethernet device is an ACP attached to the IF: driver (for the
specific unit), and which in turn implements all the logic of
communicating over ethernet, including ARP.

And then of course, is the tools, which are perhaps a bit more OS
specific, but they are smaller and simpler for the most part.
Applications (if everything else was ported) would probably work without
any changes.

Johnny,

Could it be ported to RSTS/E V10.1? That's what PLUTO:: is.

This is perhaps slightly offtopic, but fun enough that I like
to announce it anyway...

Ok. I just thought I'd stir some interest and just general
noise by announcing that I've written a small web-server
running under RSX.
It's written in BASIC+2, and uses the TCP/IP stack for RSX
that I've also written. There are probably a bunch of bugs
and issues still around, so I'm happy to take any bug
reports, comments or whatever.

The url is http://madame.update.uu.se/, and if anyone is
curious about the code, it's at mim.update.uu.se (same
machine, other IP), under MIM::DU:[HTTPD]WWW.B2S (also on HECnet)

If people have any interest in this stuff, or something
else/more, I'm interested in hearing about it. The TCP/IP
stack will eventually (soon) be available for others to
download and use, and apart from the web server, I've also
written a telnet client, and a few small services under TCP,
as well as some tools for administration. I have some
polishing to do, I need to finish a DNS resolved, and I'd
like to also finish FTP and a telnet server, but I might be
open to distributing things before I've finished all those
things, especially if someone is interested in helping writing stuff.

I have interfaces completed for BASIC+2, PDP-11 C, Macro-11.
FORTRAN 77 should also work, but I haven't tried it yet.

This all runs under RSX-11M-PLUS V4.6, but I think it should
be possible to get running under almost any M+ version, but
there might be some hacking needed for some versions.
It will not work under 11M, and I never expect it to. One or
two drivers as well as one or two tools really are big enough
that I need to use the split I/D space feature in M+.
Rewriting stuff to not need that is way too much work.
