[comp.protocols.tcp-ip] PC/NFS and Packet Drivers, Alternate Telnet's

karl@naitc.uucp (Karl Denninger) (08/23/90)

Well, we're getting there.

I have PC/NFS working with the Clarkson packet drivers.  I have NCSA Telnet
working with same (all the way to 2.3b8).  That's fine.

What isn't fine is that I can't manage coexistance.  I have tried the NCSA
version from Clarkson that is supposed to work with PC/NFS, and all I get is
a hung session when I connect (it does initialize properly).  Curiously
enough, I can hit <ALT>M a few times and get on, but it appears that no
processing is taking place until I go away from the display screen!

Needless to say, this is a real bummer.

Does anyone have any ideas for coexistance on these?  I'd really like to be
able to use NCSA Telnet and PC/NFS simultaneously, 'cause the Telnet that
Sun supplies with PC/NFS stinks to high heaven, and some of our users really
want things like the Tek mode and 3270 capability....

Ideas or further suggestions solicited.

The problem lies in the packet driver. Although it is designed to serve
multiple clients it is unable to provide several clients with
THE SAME packets. This is neccessary because the PC/NFS adaptor (PACKET.SYS)
registers for ALL types of incoming packets (also those for the telnet
running in foreground).

We have a solution here that consists of a modified packet driver.
This one is able to deliver incoming packets to ALL clients that have
registered for a specific type by just copying it to the various
client areas.

The modification changes only HEAD.ASM common to every
ethernet card driver. For us it works fine with PC/NFS with WD8003E card.

If there is great interest I'd like to know where to post it otherwise
Karl, just ask me to send it to you.
