I'd quite like to have a go at running an area. Will OpenVMS VAX 7.3 w/corresponding UCX install suffice for tunneling DECnet-over-IP (RFC1006) to other HECnet routers? Don't know the answer to that one, but Bob Armstrong and others do. I hope they'll chime in. Does UCX do DECnet tunneling over IP? AFAIK it has no such feature, but I haven't used it for years. If it does, then I'm afraid I know nothing about it. FWIW, I switched from UCX to Multinet years ago because the Multinet implementation was much more complete and much less buggy. If you're a hobbyist you might want to consider switching too; there is a free hobbyist license program for Multinet and other Process Software products. Bob
