We're thinking about getting a NeXT machine and I wanted to check whether
it could be used by others remotely to run Mathematica. We have Mathematica
running on a Sun workstation and I can log into the Sun and run it (of course
I don't get the PostScript graphics, just terminal graphics) or access it from
the Macintosh front-end over a serial connection (9600bps) or ethernet via
TCP/IP (I imagine also via a AppleTalk to Ethernet gateway like a FastPath).
Obviously, the second solution is much better.
What I need to know (since I don't have a NeXT available) is whether I can
run the Mac front-end to the Mathematica kernel running on the NeXT (the version
of Math. on the Mac for instance doesn't let anyone else access the kernel).
Does the command mathremote exist on the NeXT? To run the Mac front-end
I first log into the machine running the kernel and type mathremote and then
return to the Mac and tell it to continue talking to the remote kernel.
Along the same lines, can the reference material, Webster's dictionary,
thesaurus, Shakespeare, quotations be accessed via users who have telnetted to
NeXT? Is there any other way? - I remember reading something about a Webster
server.
Thanks,
Shmuel

Yes, you can access the NeXT Mathematica kernel from a Mac. I have done it using a dialup connection, but the manual for the Mac version mentions that you can also do it over a network if you have the right software. You are right in saying that it is a one-way street -- you can't access the Mac Mathematica kernel from a remote machine. > Does the command mathremote exist on the NeXT?

Try "man mathremote" on a NeXT. Using the Mathematica front end on the Mac, you can open a terminal window and use it to log on to a remote machine and then use the "mathremote" command to start up the remote kernel. Then you can close the terminal window and return to what looks like normal operation on the Mac. > Along the same lines, can the reference material, Webster's dictionary, >thesaurus, Shakespeare, quotations be accessed via users who have telnetted to >NeXT?

There is a publicly available program called 'define' that lets you access Digital Webster from the typescript or from a telnet session

The server is available from iuvax.cs.indiana.edu [129.79.254.192] as pub/webster/NeXT-websterd.shar.Z There are two divergent versions of the UNIX client: webster-client.shar on iuvax offers access to more server features. pub/webster.tar.Z on wolvesden.stanford.edu [36.8.0.179] is "better code" and will work on System V-derived machines (with sockets, not TLI) as well as BSD-derived systems. It also includes an emacs client. (Someone should look into reconciling these...) Please note that RFC 1060 "blesses" port 765 for webster, which should be used instead of the 103 or 2627 in the above versions. BTW, since I'm still waiting for NeXT to ship us 2.0, I would be interested in hearing if my icrwebster (which displays the TIFF illustrations on Mac IIs with NCSA Telnet) still works. -=EPS=- -- Digital Webster doesn't know the meaning of the word "backorder."

>The server is available from iuvax.cs.indiana.edu [129.79.254.192] >as pub/webster/NeXT-websterd.shar.Z I wrote this. To forestall the inevitable questions - this daemon doesn't work with 2.0 yet, but as soon as we get 2.0 here I will make it work and publish either patches or a new version. The format of the Webster database changed drastically with 2.0. It used to be simple at 1.0 - the index file was a simple list of words and byte-offsets into the actual dictionary file, and it wasn't too hard to parse the dictionary file entries either (especially if you had a copy of the real 9th New Collegiate Dictionary handy.) There was also a "libtext" library that simplified access to it (although my websterd didn't use it, since I wrote it for an 0.9 machine before libtext was available.) Now, it's all based on B-tree's and it's not the sort of format you can puzzle out just by staring at it, and libtext isn't included with the OS any more. If you ask NeXT nicely they will send you the appropriate btree and libtext libraries. So I don't anticipate any problems coming up with a 2.0 version of websterd; it might not happen until late February though. I'll post a note when I get it all tidied up.
