Don't try to talk with anything but VMS, though... ;-) Does the DECnet/Linux just not implement RTERM? Or are there deeper problems? Don't know. But they do implement CTERM. But it only works against VMS. Same for NFT and PHONE. The implementors have only had VMS systems to test against, to their defence. And I think it might be a piece of reverse engineering on their part as well. I'm pretty sure I was able to connect to my RSX-11M 4.2 system back nearly 10 years ago using DECnet/Linux. As I recall it didn't work the best, but at least I was able to log in and do some stuff. It's worth knowing that DECnet for linux has two 'set host' programs. sethost is an old one written by Eduardo and (I think) has some rterm code in it. It only supports a small subset of the protocols though so things like line and screen editting (on VMS) just don't work. I rewrote dnlogin from scratch fairly recently (well, in the last couple of years or so!) and though it's only really been tested to VMS it's a LOT better than sethost. It only does CTERM though.

I'm guessing your bridge software plus an emulated system running software with routing else a hardware router of some description. I believe I've always run Phase IV on my area router, but then it's also running VAX/VMS V5.5-2. I was originally running Phase V on my Alpha, and I believe OpenVMS 7.3-2 at the time, but once I was on HECnet I quickly *upgraded* it to Phase IV, as it has less problems talking to other systems. IIRC, DECnet/E might have been one of the big reasons for moving to Phase IV, but then DECnet/E has problems with just about anything. :^( The software support for a tunnel would be really useful in SIMH, since that would cover not only PDP-11's, but VAXen as well. Support in KLH10 would be nice as well. Zane -- | Zane H.

What you need to be aware of is that the DECnet routing license isn't included in the VMS hobbyist program, so unless you have some other license for that part, you will not be able to actually do this.

It might be that you need phase IV for that part, but this is something others will have to verify.

With my bridge program, you don't need to have any routing nodes at all. Well, yes, but I like the idea of operating an area and playing with routing. You know, adding complexity for fun. Feel free. :-) Just let me know when you want to take care of the details. Johnny

DECnet/Linux tunnels

I did attempt a multinet daemon for Linux but I haven't tried it for ages, I can't remember how useful it got! Well, if you take requests I think this would be a useful alternative for connecting to HECnet. IF I can do something to help (setting up a connection; TCPDUMPs, whatever) let me know. Bob

A couple of years ago I think Mary Berryman was able to get his Cisco router talking to a Multinet tunnel using IP/GRE but I don't know if he had to do any tweaking to get it to work or not. -- Chrissie

Quiet list and a question about setting up a system

by bob＠jfcl.com

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
