[comp.sys.mac] Problem with TOPS/Ethertalk on Mac SE

florijn@serc.nl (Gert Florijn) (04/12/90)

Hello,

We're having some problems with the integration of a Mac SE into our
TOPS/UNIX network. Although local reps are looking into it, I hope that
some guru out there can provide some clues to the source of our
problems.  Please use e-mail for answers, since I won't have time to
consult comp.sys.mac in the next few weeks. If there is enough
material, I will summarize. In case my mail-address gets munged, the
signature at the end provides some possible addresses.

The setting is as follows. We have an Ethernet of UNIX workstations
(among which are some SUNs). We have a Mac II cx that is directly
connected to the Ethernet (using Ethertalk) and we use TOPS (version
2.1) to communicate with a Sun server.  This setup works fine, and has
done so for a few months.

Recently we obtained a brand-new  Mac SE also equipped with an Ethernet
interface and Ethertalk. Of course we want this one also connected to
the UNIX machines via TOPS,  so I installed the only copy of TOPS for
the Mac that we had (the one that also runs on the MacII) on the SE,
and connected the machine to the Ethernet.  Of course, I selected
Ethertalk from the networks accessory.

The problem that showed up is that the SE doesn't see the UNIX server.
At least, the server doesn't appear in the server window when you open
the TOPS accessory.

I know that each Mac-TOPS copy is licensed, and that two copies of one
version in the same network won't work together. We have ordered the
extra copy of TOPS, but it hasn't been delivered yet. But anyway, this
isn't the cause of the problem. I have disconnected the Mac II from the
network completely leaving only the SE on the net, and restarted the
TOPS service on the UNIX machine.  The result stayed the same: the SE
doesn't see the server.

We did some further checks. We obtained an older copy of TOPS (2.0) and
installed that on the SE. We hooked the two Macs up in one small
network, and published some folders on the Mac II. You guessed it, the
SE still doesn't see the server.

In my opinion there can be two sources of this problem.  The first one
is that the Ethernet card is broken. I don't have any idea on how to
check for this on a Mac, so any clues on how to do this is appreciated.
The other potential problem I can see is that TOPS 2.1 depends on
certain versions of system software like Ethertalk. The MAC II has
version 1.2 of Ethertalk (and OS 6.0.3), while the SE has version 2.0
of Ethertalk (and OS 6.0.2).

Well, that's it. As I said before, any clues, either pointers to
solutions or ways in which I can check for certain problems, are
appreciated.
