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

[Steve Davidson]

Well...

While the two Oses ARE different they do share quite a bit.   I used to
support RSX (and IAS) at the internals level when I worked in the
Corporate Operations Group/Software Services/Real-time Group (RTG) at
DEC so I'm quite at home with the RSX family of systems.   I use RSTS/E
in day-to-day tasks here.   I am out of practice but it wouldn't take
that much to come back up to speed programming wise.   I also used to
teach MACRO-11 to Software Services Personnel.

This could be fun!   It will certainly be different!

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.
