[comp.unix.xenix.sco] TCP/IP connection between Xenix and Macintosh

lance@embassy.nsi.com (Lance N. Antrim) (10/21/90)

with tcp/ip 1.0.1 and my Macintosh running NCSA Telnet.  When it works,
it works great.  It even gives me dial-in access to my files on te Mac
via ftp.  However, my ability to open a session from th Mac to the Xenix
box is intermittent.  There is always a connection, but sometimes it
holds for a login and sometimes it doesn't.  If it didn't connect at
all, then I would have some ideas of wht to look for, but when it works
10% to 20% of the time I am at a loss.

Has anyone had similar problems of intermittent connections for telnet
sessions?   Since I do get some of the connections, I know that the files
(/etc/hosts and other related files) are all there and correct, so I am
stumped.  Suggestions will be appreciated as I am just learning to set
up and administer tcp/ip and telnet.

Thanks,
Lance Antrim

I have had similar problems with the MIT/CMU PCIP telnet protocols trying to 
log on to Xenix.  It would occasionally work but when we went from 1.0.1d(c?)
to 1.0.1h it seemed to get worse in that now it won't work at all.  FTP software
(the company) telnet and rlogin do work fine and since they are from the same
obviosly, FTP made theirs more robust but I don't know what they did.  It's been
a low priority problem around here but if anyone does know why, I'd be delighted
to hear about it.  (The PCIP stuff works just fine logging into Ultrix on a VAX
and Wollongong TCP/IP for VMS.)

There are problems with how the SCO telnetd deals with certain Telnet
terminal type option negotiations; NCSA Telnet seems to especially
aggravate this problem. I believe SCO is readying a 1.0.2 release of
SCO TCP which I hope will solve this bug. I have no idea when it will
be out, though.

Actually, FTP's telnet is very different from PC/IP's. The TCP and the
telnet are complete reimplementations from the ground up. The telnet
handles many more options, and does option processing differently.
PC/TCP was based on PC/IP, and the version 1 series of the product did
substantially resemble PC/IP, but the version 2 code is very
different.
