In a few days I will finally get my hands on a machine to learn
OpenVMS on (an AlphaServer 1200). Before then I must figure out what
TCP/IP stack to use. I know almost nothing about any of them and dont
know very much about how to use OpenVMS in general.

Multinet and TCPware seem to be made by the same company and their
website pages seem almost identical. I assume there must be some major
difference between them - I dont see any reason why one company would
make two seemingly identical products for the same platform.

Could anyone tell me which TCP/IP stack I want to use and what are the
major differences between them?

If you're new to OpenVMS then just install the HP stack that comes on
the distribution media. You didn't say what version of OpenVMS you
have, but any recent (V7.3.-2 and later) version is adequate for home
and learning use. If you have the latest versions (OpenVMS V8.3 and
TCP/IP V5.6) then you have a very good combination.

All three TCP/IP stacks will do the job and are overall pretty equal
in features and performance. Each also has advantages in different
areas. The HP stack has the advantage of being the vendor supported
one. Installation is easy and the setup is fairly painless for
typical usage - especially for use on an internal network in a general
server role. Once you get a little more advanced and if you want to
put your system onto the internet then you might consider one of the
two offerings from Process. Both TCPWare and Multinet seem to have
features which lend themselves to internet use particularly in dealing
with SMTP mail processing and VPN options. I'm not an expert on
either, unfortunately, so hopefully their various proponents will
chime in also.

Hope this helps.
