Subject: problem w/ Telnet printers


We are having a problem with a possible bug in the
Telnet program, and I was wondering if you had any
similar reports and/or solutions.  When trying to
print a highlighted selection from our UNIX hosts,
we frequently lose all printing capabilities.  After
choosing the proper chooser/setup/print options, there
is a long delay after which it is impossible to print
anything without leaving Telnet and logging in again.

If you have any ideas what may be causing this, or if
you have any possible solutions, your help would be
greatly appreciated.  I understand there is a newer
version than our 2.2.  Has this version corrected this
problem and could it be helpful in our solution.Thank You.

problems here.  Is this only happening on AppleTalk nets?

Subject: lost data on ftp transfer

I have had several occasions of undetected lost data in the middle of
a transfer from floppy on mac through ftp to unix host.  I suspect my
floppy drive.  Could you please take a look at the telnet file transfer
code to ensure it correctly detects short-read IO errors?  This means
erroring if you get less than should be there, not just erroring if no
data at all is transfered...  My suspicion is that bad floppy read is
coming back with short transfer length, and ncsa is not detecting...


[The code does not check short-reads.  I have never traced a problem
to short reads, but that doesn't mean anything.  Is this a common
problem?

Subject: Closed connection, keyboard mapping

I use NCSA Telnet V2.2 for the PC.

In response to a recent note about the "Connection closed" prompt, I
think it'd be nice if you could hit scroll lock and page back through
the session even after the connection was closed.

Also, it would be nice if the special keys (function keys, page
up/down, etc.) could be remapped somehow--I'd like to use them inside
Emacs, but some of them are prefixes of others, so they can't be
distinguished.

Thanks!

There is no packet driver for the BICC Data Networks ISOLAN, nor is anyone
working on one, to my knowledge.

Subject: Re:  NCSA Telnet Digest V2.25

With 2.3 for the Mac almost out the door, and Tim K promising to incorporate
some of the changes from the Clarkson variant of NCSA Telnet for the PC,
perhaps it's time for a wishlist.  Here are some things I'd like to see
soon in versions of Telnet:
    for the Mac:  an FTP client.  BYU and Intercon both have them in
        NCSA variants.  This is the single biggest request I get
        from my users.  I tell them "use Stanford Mac/IP".  Most
        people who start using the Stanford software on the Mac
        don't come back to NCSA.
    for the PC:  integrate some of the changes from Clarkson.  The
        changes seem to be in 3 areas:  packet driver support,
        BOOTP support, and tn3270 support.  I see the first 2
        as being *very* important for integration into the standard
        NCSA version, and the last as being difficult to integrate.
        I recommend not integrating the tn3270 support, but
        continuing to point people at a Clarkson variant if they
        need it.
        The major remaining area of problem for PC users is the
        keypad.  The standard NCSA mapping isn't bad, but differs
        from kermit and from other VT emulations on the PC.  A
        simply programmable keypad would be desirable.  As an
        alternative, a PD TSR to do key mapping in the
        user-contributed directory would be adequate.
    for both:  there are numerous minor problems in both the VT
        emulation and in the TCP support that don't seem to be
        causing many operational difficulties, but are inelegant.
        They should be addressed as time permits.  One major
        IP problem is lack of support for fragment reassembly.
    documentation:  with the proliferation of variants, the documentation
        should probably mention their existence and something about
        them.


[We'll hit quite a few of your wants in the next couple of months.
For the VT emulation - please send me dumpfiles which demonstrate
errors and document what the procedure SHOULD do.
For client FTP - I say buy TCP/Connect from InterCon.
BOOTP, packet driver and keyboard mapping sound doable to me.
IP fragmentation can almost always be avoided, set your maxseg parameter.

Subject: Problems with Telnet and TeleBridges

We've been having a variety of weird problems running NCSA Telnet
versions 2.2, 2.2.3(BYU) and 2.3b4 on Mac Pluses and Mac SE/30s
across a pair of Shiva TeleBridges connected by Telebit T2500
modems through a FastPath 3 box to our 4.3BSD VAX 11/750s, and
were wondering if anyone on the list can offer insight into our
problems.

1. Telnet would time out before finding the FastPath box and
   assume that dynamic address assignment was unavailable.  We
   found that this was caused by running the Telebits in PEP
   mode, which seemed to slow the connection down so that the
   FastPath took 1.7s to respond to an NBP query.  We reconfigured
   the Telebits to run V.32, and also patched the Telnet code
   (don't have MPW C, sigh...) to use a longer retry interval,
   and things work fine now.  Could the NBP and ATP retry interval
   and count be configuration options in some future release?

2. Sporadically, with a mean time between occurrences of something
   like a few hours on a directly connected TeleBridge pair or perhaps
   a quarter hour across Telebits, the following happens.  Telnet
   terminal emulation freezes (hitting keys on the keyboard does
   not result in packets being transmitted), and the entire AppleTalk
   zone (on the Telnet side) becomes invisible to the rest of the
   internet with the exception of the TeleBridge itself.  Running
   Inter-Poll to examine the network on an SE/30 adjacent to the
   Mac running Telnet causes Telnet to unfreeze (!) sometime between
   hitting return at the alert warning you that Responder is not
   installed (even though it is, because it's an SE/30), and the
   network selection window's appearance.  I find this totally
   baffling, and am poring over a Peek log to try and figure this
   out.  Since no other software (TOPS, AppleShare, TOPS Terminal,
   various diagnostic tools) generates this problem, I conclude that
   somehow Telnet is managing to thoroughly confuse the bridge (though
   I would have thought that this was impossible), which is only resetting
   itself when a second mac sends it a packet.

3. When we were running the TeleBridges without the modems, on a
   straight serial line, after a few hours of running, a phenomenon
   similar to #2 would occur, except that the zone with the Mac running
   Telnet would vanish from every bridge's routing tables, and would
   not re-appear until a Mac in that zone ran the Chooser.

 Are there plans for the ibm pc and the mac ncsa telnets to support
 lpr?

 JoAnn

[We have some user contributed lpr code for the PC which we are testing.
lpr is not particularly practical for the Mac because it won't be able
to print MSWord or other PostScript stuff.  It would be of limited use.

Subject: Re: Telnet 2.2 on PC in Server Mode

I found an easy workaround to run telnet 2.2 with the 3c501 card as a
server:  Add a host name "server" to config.tel with a bogus internet
address.  Then enter "telnet server".  Telnet tries to connect (warming
up the ethernet board), fails, and reverts to server mode.

Subject: TEK GIN mode ?

Has anyone implemented GIN mode for the TEK emulator in NCSA Telnet?

There's no mention (that I can find) in the docs, and I've yet to check
the sources.

I'm using a beta version of NCSA Telnet v2.2 with SLIP from cisco, to
test with their terminal server.  Any modifications would have to be
passed along to cisco, since I have just the binary for testing.

Any help, pointers or ideas are appreciated!

Subject: NCSA-Telnet does something to Multifinder !?

I run NCSA-Telnet v.2.3b4 (I had the same trouble on earlier versions)
on a Mac SE, System v.6.0.3 and Multifinder with the same version number.
The problem is:
Just after booting everything is OK. I run MS Word and HyperCard and
switch between applications.
BUT. After starting NCSA-Telnet my trouble starts.
 The indications are: If I run MS Word, close all
windows and then click on the desktop, I get the message that "MS Word
has unexpectedly been aborted" (I get it in norwegian so this might
not be the correct english message). The mouse freezes and all I can
do is restart.
The same thing happens when I run HyperCard. It is OK to switch to
Finder, but clicking the Mac icon to get back to HyperCard results in
the same message as above. And the mouse freezes and I have to
restart.
By the way, I use Gatekeeper, but the same things happen even if I
"override" it just after booting..
I am not certain that Telnet is the root to all this evil, but as I
said, nothing happens before I start Telnet.

Kenneth (irritated)

PS. Besides this, I think NCSA-Telnet is great!


[I don't even know where to start looking.  I run MSWord and NCSA Telnet
together on my system every day without this problem.  Tim K]
