I have the oportunity to add DNET as an option on our public access unix
machine (D.I.S.K.) so our Amiga users can run multiple sessions, etc. But
we only have SYS V unix. I remember when DNET came out it was only for BSD,
and that there were some of you out there who wanted to get it to work with
SYS V.
At the time I had no use for DNET, but now that I do, I am wondering if anyone
has finally gotten it to work with SYS V, or is Matt going to come out with a
SYS V version?
Many Amiga/Unix users will appreciate it if DNET on SYS V is possible.
Does it/ will it exist?

This is an important question for me too, since my workstation is a
Sys V machine. It would be really cool if I could multi-window
terminals and access to NFS on my Amiga through my Iris.
I would be interested in doing a port of DNET for Sys V, but
unfortunately I'm not Matt Dillon and don't know a whole lot about
Unix system-level hacking. That doesn't mean that I'm not willing to
learn, but I'd first like to hear from some other people who have
either done the port already or are already working on it, to save
myself from repeating effort if possible.

The problem with DNet under SysV Unix is that it depends heavily on
Unix-domain sockets in its current implementation. You'd really need
a replacement. For a SysV machine with TCP sockets available, that
could work. But without some sort of sockets, you are basically left
with the pipe() call for IPC... which is useless for unrelated
processes. (How would you propose to implement putfiles?) You could
resort to something like shared files or some other form of IPC, but
that's ugly. I'm not sure if standard SysV has any useful form of IPC
between unrelated processes you could tap for DNet. Streams?
Probably not, and not widespread yet. Messages? Maybe, but I don't
know how and how widely they are implemented. Anyone with SysV
networking (standard) info?

Well, as it turns out, SysV Unix for the Iris supports TCP sockets, so
it may be possible for me to port DNet so it runs on my workstation.
So now my question is: How good would this be for the majority of SysV
users out there? How many SysV ports offer support for TCP sockets?
I'm still interested in hearing from anyone else who may be attempting
the same task or thinking about it.

I'm not sure how many SysV machines support TCP, but I know they
exist. If there's a socket library, all the better. It might not
even be too hard to do... [then again, Matt's code is pretty ugly...]

Oh, I've considered it, and may eventually do it, but it's
low-priority queue. (i.e. probably won't bother to attempt it anytime
real soon... I've got DNet running on a BSD (SunOS) machine, so I
haven't the incentive.)

I do know some guys who are pretty good at it though, so .... can anyone give me details on what to change in order to get DNET working on SYS V with TCP sockets? we are running on a 386 machine with microport unix.

As far as I know all System V ports done by Unisoft (e.g. Apple's AUX) have something called B-Net. Unisoft ports mostly to 68K boxes. They do not sell UNIX boxes. The B-Net is the 4.2BSD networking code, so you shouldn't have a problem getting DNET going there. For pure SysV boxes "a full redesign might be in order" as they say ;-) .

Or, consider running SLIP from an Amiga under Exec to one under Amix. Whether sockets will be supported in Amix, I don't know. What _type_ of sockets such would be is equally a mystery.

Why couldn't named pipes (fifo special files) be substituted for Unix-domain sockets? They seem to be very similar to Unix-domain sockets.
