When running an Emulated VAX/Alpha in a VM, you may need to create the MAC addresses for the emulated network adapters to be the MAC address that decnet will assign them.

I just stumbled on a site that makes it easy:

Just enter in your Decnet Phase IV address, and click on convert to an Ethernet address.

I made a script for SCSSYSTEMID calculation.


#!/usr/bin/python3
## A script to calculate the SCSSYSTEMID value, which is used in
## VAX/VMS and OpenVMS for system identification and DECNET networking
## purposes. See: https://wiki.vmssoftware.com/SCSSYSTEMID

import sys

# Get the area, node as integers.
area = int( input( "Enter the DECNET area number: " ) )
node = int( input( "Enter the DECNET node number: " ) )

# Check for valid values. Area must be 1-63, inclusive,
# node must be 1-1023, also inclusive. Exit error if not.
if ( area not in range( 1, 64 ) ) or ( node not in range( 1, 1024 ) ):
print( "Error: invalid area/node given." )
sys.exit( 1 )

# We have valid input by this point. Calculate it.
# SCSSYSTEMID = ((DECnet area number) * 1024) + (DECnet node number)
scssystemid = area * 1024 + node

# Display the results along with the given input.
print( f"SCSSYSTEMID for {area}.{node} is {scssystemid}." )

No more VAX hobbyist licenses. Community licenses for Alpha/IA64/X86_64 VMS Software Inc. Commercial VMS software licenses for VAX available from HPE.

Just re-visiting.. No more hobbyist licenses? Is that from vmssoftware.com, no 'community' licenses?

I recall that the disks failed on the public access VMS systems that included Fafner

Anyone know what happened to FAFNER.DYNDS.ORG? I had a hobbyist account here but can longer access the site.

At one time, didn't this web site have a job board? I would love to use my legacy skills one last time in my career.

Eisner, which is currently being moved, got an SSH update and the keys were updated to more modern encryption standards.
