Um, there may still be a problem with TCP/IP ARP resolution. First, some
background: Our campus network is composed of an Ethernet backbone and an
Arcnet backbone. The two are connected through our primary Novell file
server (3.11, FWIW). We've been using Kermit with ODI drivers to connect
to the Unix hosts on our network (all such hosts are connected to the
Ethernet backbone) for about two years now. We're planning to make some
major changes in the next few months, and in preparation I've been updating
our set of Kermit scripts for MS-Kermit 3.14 and to take advantage of other
changes to available software, servers, etc.
Several days ago I downloaded the updated 3.14 mentioned above and today I
put kermit.exe and the patch files on the file server for everyone to
access. I found, though, that our users on Arcnet machines could no longer
access our Unix hosts; Kermit would complain that it could not find the
address of the gateway using ARP. (Ethernet connected machines work just
fine with the same set of files.) I suspected that there might be a
problem with the patch file so I renamed it; same result. I tried tweaking
various settings without any luck; finally I thought to try the earlier
version of 3.14. That fixed the problem!
The machines in question are running MS-DOS 6, 5, and 3.3. The ODI driver
is called TRXNET; the boards are mostly Compex brand. The only difference
between a working setup and a non-working setup is which version of the
executable and patch file is in place.
I said 'may' in the first line above because I'm not very familiar with
TCP/IP internals and how they're interacting with ODI and the Arcnet driver
and card, and I don't have the resources here to do comparison testing. I
would not be surprised to find that there's something peculiar in the
TRXNET board driver which is responsible for the error message from
MS-Kermit re. ARP. It could also be something strange with the NLM which
forwards IP and ARP packets between media. However, in case it is a Kermit
problem, I figured I should let everyone know about it. If anyone needs
more information about our setup (e.g. file dates, or whatever) please ask.
