And run the bridge program between DECNET and TCP-IP... and link/route all that to your bridge? or am I barking up the wrong tree? I was hoping to contribute to HECNET as much as possible, adding to its' redundant routing and DECNET-TCP/IP bridging. Being located on the Hawaiian islands, and not knowing any other Hawaiian HECnet nodes, I thought it might be useful as a routing point. The Linux kernel has DECnet routine built into it, it's just a matter of enabling it at boot time or it will default to an end-node. If you need something to fill in the routing tables for areas, then the dnroute daemon can do that for you. None of this is fantastically-well tested though. But it worked for me once ;-) See http://linux-decnet.wiki.sourceforge.net/FAQ2#router If you're running Debian then it's quite easy (I hope!) to edit /etc/defaults/decnet to set up routing. ...let us know how you get one!

DECnet/Linux tunnels

Does DECnet/Linux have any kind of DECnet-over-IP tunneling ability? You should be able to encapsulate DECnet in a GRE tunnel, yes. I don't know anyone who has tried it though! At one time I had a SimH VAX at on my Linux home server, and a real Alpha at my workshop. Each site had an ADSL line and an OpenBSD router, and DECnet via an Ethernet-over-IP tunnel worked fine. I had both systems in a LAVC for a while, but even a show sys/clu was slow, and occasionally the cluster would break for no apparent reason. Andrew

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. With Phase V + UCX you can definitely access OSI apps over IP (RFC1006). And I'm pretty sure I had DECnet sessions running over this, but couldn't swear to it. Seems logical though as I recall hazy memories of snippets of NCL configuration. Andrew

Heh, amazing, the folks at HP must have realised that there is a requirement amongst hobbyists for routing DECnet :o) Andrew

I've never really noticed any real hit on my bandwidth. So how do I get started with the node numbers and what-not? Hopefully Johnny will show up sometime soon, he is the central registry for such things. You need to figure out if you just need a node number or two, or an area. Most people don't need an area, and in order to have an area, you need an area router. I suspect most of us have our own areas for historical reasons (i.e. one of our systems was originally in such and such area). Right. If anyone wants an area, and have an area router, just say so. There are still plenty of unallocated areas, and I don't really see it as likely that we'll run out of them. Johnny I'm new to this... is there an area router software for Linux?

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. Sounds like the situation might be better now then. Maybe someone could try? As for the problems with DECnet between Linux and RSX I should point at that it's been applications that I've had problems with. The basic DEcnet protocol implementation as such is, as far as I know, working fine. Oh, I'm sure that's true. As you say, they've only really been tested against VMS as that's what I had available at the time. OK I now have access to other systems via HECnet but I don't have the time to do anything about it ... that's just life, sorry. I do take patches though ;-) -- Chrissie
