[comp.protocols.tcp-ip] tcp-ip to Decnet

sparks@etch-eshop.Berkeley.EDU (Jay Sparks) (09/06/90)

I am wondering if shareware is available for tcpip to
Decnet.  The idea being to connect a Sun with an ethernet card
to a VMS machine.  
Thank you,
Jay Sparks

The easiest thing to do is to run TCP/IP on your VMS system; there are a
number of packages available. I use the version from CMU; it is very
complete and works quite well (at this moment, I have some windows on my
NCD X terminal which use CMU TCP/IP as the X transport). I am told that
it costs $150. The commercial packages cost more, and would give you
support, and a different feature set.

You'd probably get better answers on comp.os.vms.

There are actually a number of TCP/IP implementations for VMS and at least
a couple of DECnet implementations available for Suns.  In addition to
SunLink/DNI, Thursby Software (Arlington, TX) has a DECnet for SunOS (and a
few other UNIXs), and KI Research makes a DECnet and MOP for several UNIX
platforms (not sure if that includes SunOS, though).

The TCP/IPs for VMS that I am aware of (listed in alphabetical order) are:

Board-based:
------------
	CMC
	EXOS from Excelan/Novell
	Interlan

Host-based:
-----------
	CMU/TEK from Carnegie Mellon University
	Fusion from Network Research Corporation
	MultiNet from TGV, Inc.
	TCPware from Process Software
	WIN/TCP from The Wollongong Group

If you fire off a query to info-vax (probably the best place), I'm sure you
can get some recommendations from users as to the good and bad points of
each of the above VMS TCP/IPs.
