1. DECnet. NFT will use the DAP protocol to do file transfer; if you
have a compatible DAP implementation at the other end that would
work. DECnet/Linux can do this, I believe.
If you can find it DEC PATHWORKS apparently still works on Windows XP,
of course you'll need to fire up a VM for it in most cases; and
DECnet/Linux has basically become unsupported.
Don't dismiss DECnet/Linux as a viable solution. It's true the
DECnet/Linux community is small and the main players of long ago are
gone. But, that doesn't mean it does not work.
I have been a long time user of DECnet/Linux, mainly on CentOS. We use
it for backups over DECnet mostly, and file exchange. Stand-alone
backups work just fine. When the disks on my last CentOS version went
belly up, I decided instead of a dedicated DECnet NAS, it was a better
idea to use our NFS disk farms for storage. I built a couple
DECnet/DAP-to-NFS gateways using a Marvell SheevaPlug "PlugPC" with a
Kirkwood ARM SoC (no FPU). I am at home at the moment, so I cannot tell
you what Linux kernel I used. I haven't checked on them in a long time.
As far as I know, they are working just fine. One is used every day
to export files from a VAX/VMS 5.5-2 data acquisition system to an iMac
file server. That VAX has been running that lab for over 20 years, I
think—maybe 30. We used to run Pathworks/Mac on the VAX until Apple
removed support for their own network file protocol and forced us to
come up with an alternative. We run DECnet Phase IV, not Phase V, so we
can't do DECnet remote file access over TCP/IP. I've built other SoC
appliances using PlugPCs, such as Ionics Nimbus. My last few projects
using SoCs have used BeagleBone Blacks. Their processors have FPUs,
which makes them more useful. As I recall, Raspberry Pis either did not
have an FPU, or priced out more expensive than the BeagleBone Black when
I last looked at them. I set them up to be self-hosting for
development. Cross-development is a royal pain.
Just a short comment. Linux/DECnet do not play right with RSX. The
development was all done against VMS, and it would appear to have lots
of bugs that were never ironed out. Success against anything except VMS
is dicey at best (unfortunately).
