Yet another OpenVMS DCL Command Procedure to Crawl and Report HECNET the Hobbyist DECNET in HTML served by WASD - OpenVMS VAX 7.3

"What is HECnet?

HECnet is a DECnet that connects different people who play around with different machines that have the DECnet protocol suite. The network should not be regarded as a serious networking setup, nor should it be expected to work 24/7. It's a hobby project between people who think it's fun to create a DECnet network.

HECnet is basically a DECnet phase IV network. Currently, the main router is a PDP-11 running RSX-11M-PLUS. The machine is located in Uppsala, Sweden.

The connectivity between nodes can be anything that works. The current connectivity is with an ethernet bridge between sites, DECnet over IP using Multinet on VMS or RSX, and DECnet over IP on Cisco. Other solutions that have been used are a virtual serial async. connection talking DDCMP. Other possibilities are GRE and DECnet over IP." - read more at
