Subject: 3c501 Server problem


That server problem mentioned in the latest issue of the digest has
been around and troubling me for quite some time. I was hoping it might
go away in version 2.2, but alas, it's still there.

Here's why I haven't written in about it before:

1. It's not too important, since we usually are at the machines and the
easy work-around is to simply log into something.

2. It's very intermittent! This is most frustrating, because our LBLNet
is a large Ethernet backbone with multiple subnets hanging off it. It's
a complex system that, as you might imagine, has its own intermittent
problems. So I naturally assumed that the intermittent nature of the
problem pointed not to Telnet but to our systems... The server seems
to start around 30-50% of the time, depending on what I was just doing
with the AT. I just assumed it was related to the evolving state of our
nameservers, domainservers, and continual experimentation and development
on the system.

The computers in question are all IBM AT's with 3c501 boards. They're
8 MHz systems, with lots of memory and all pretty much look the same.
Some have the problem and some don't! Those that do, sometimes don't, and
those that don't sometimes do!

I'm glad you have some idea to fix it, because I thought you'd just get
a good laugh out of it if I sent you the description in the last
paragraph... I should have known better.

Thanks,

Jack Zelver

Subject: dynamic ip address assignment on ethernet


Hello!

    The Kinetics Fastpath 4 running K-star release 4.1 can apparently
assign ip addresses to Macs if the option 7 is set.  I tried it with
NCSA 2.2 and 2.2b5 with dynamic assignment on and it looked for a rarp
server and then quit (from a MacII with Apple Ethertalk card and
hardware=Ether set in the config.tel).  Will this be supported in
future versions, or is there some magic botton I've overlooked?  It
would be a very handy feature...  Thanks

To my knowledge, the K-Star dynamic IP assignment is KIP-style IP number
assignment which we have supported on LocalTalk since v1.1.  When you
use Ethernet for TCP/IP, we don't even initialize the AppleTalk protocols
as they are not needed for communication.  What I think you are asking
for is for us to query a LocalTalk server for an IP number and then use
that number on Ethernet.  What we do instead is query for a RARP server
on Ethernet when "dynamic" is selected.  We may query for a BOOTP server
in the future, but probably won't elect to query a LocalTalk server for
an Ethernet interface.

I'm looking for Macintosh or IBM PC source code for tn3270.  Can anyone point
me in the right direction?  Please e-mail to me.

Many thanks,

We don't provide any tn3270 support in NCSA Telnet.  Can someone provide
this information?  Tim K]

  I don't see support under Mac NCSA Telnet 2.2 for the EtherLink/SE
  board from 3Com in the info.sheet file acquired via anonymous ftp.
  Can someone please confirm this for me?

  thanks,

Subject:      EtherLink/SE support?


 Hi!  I am reading info.sheet regarding Mac NCSA Telnet vers 2.2 -
 I don't see support for the 3Com EtherLink/SE board listed.  I am
 kind of surprised cuz the board is about $100 cheaper than the
 EtherPort SE from Kinetics.

 Can someone confirm that the EtherLink/SE is definitely not supported?

 thanks,
 JoAnn [e-mail] or (thru bitnet) tksjmi@ubvm

[
Our original information sheets were produced before this board existed.
3Com has provided us with a test model and EtherTalk driver software.
They both work perfectly.  We will be adding the EtherLink/SE to our list
of boards.  It, like many other devices, is compatible with EtherTalk, so
the standard NCSA Telnet 2.2 works unmodified.

Subject: 3270 for PC version of NCSA-Telnet?

I just received my copy of Telnet 2.2 for my PC.  I had heard of it at the
INTEROP 88 conference, and I had rushed an order through NCSA.

In my eagerness, I failed to question/notice that the feature list of the PC
version lags behind the MAC version.   Most noticeable to me is the lack of
tn3270 for the PC.

Is tn3270 in-work for an upcoming release?  I sure hope so. The features of
NCSA Telnet cover such a useful set as-is, and the addition of tn3270 would
really cover the majority of my users' emulation needs.

For the less than 10% of my users, is there work in progress also for the
DEC VT241?  How about the TEK4105?

I consider myself a sophisticated user, but I don't even pretend to be a
communications programmer.  I have to probe around to find what the really
clever code crafters come up with.

Looking for help....

NCSA does not plan to support tn3270 in any way.  We redistribute Brown's
version of tn3270 for the Macintosh via anonymous FTP.  There are no
current plans for VT241 either. We are working on Tek4105 support.

Is there a tn3270 for the pc version of ncsa telnet ? If so, is it written
in C, or what ? Is the source available? What C compiler would I need ? Any-
thing else (software) I would need besides ncsa telnet ?

Has anyone managed to get this working, or made any plans to do so?
I recall that one of the developers of NCSA posted here'n'there about
this a while ago -- any good news?

Thanks,

No good news yet.  We have the materials, but no working code yet.

     Are the NCSA drivers compatible in any way with the Unix socket library?
Will they be so, or is anyone working on this?

NCSA's TCP/IP kernel has many specific design elements which are tailored
to microcomputers.  For this reason, the library calls are not
perfectly compatible with the Unix calls.  They were designed with C and
Unix in mind, so you won't find it a big stretch to make your code work.
