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

[Steve Davidson]

I would be VERY interested!   No sense reinventing the wheel...

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.
