DECnet-10

by gerry77＠mail.com

Hello all, does anyone here has any experience running a TOPS-10 host with DECnet-10? More than a year ago, we connected to our DECnet a KLH10 emulator running TOPS-10 and its DECnet-10 software, but we had to shut it down just after some days because it was causing us many troubles and had serious usability issues. Now we would like to try again, so I'm writing here looking for some ideas. We would prefer to use KLH10 instead of SIMH because of its quite interesting multiprocess implementation which scales way better on the hosting system. Moreover, the KLH10 emulator uses a very effective idling mechanism, by means of a special device which has to be accessed by the guest OS in its idle loop. Activation of both this idle mechanism (patching CLOCK1.MAC) and DECnet-10 requires a monitor rebuild, which should be almost easy because we have all the sources and instructions, but which is actually not so straight-forward. By reading manuals and Usenet posts, we found that we'd have to use the MONGEN procedure to rebuild the monitor. So we patched CLOCK1.MAC and answered all the relevant MONGEN questions about DECnet, but the final result was not good. (Probably we ran NETGEN too, but at the moment we are not sure about this). DECnet did start and we were able to make connections to and from the TOPS-10 host, but other parts of the system (e.g. BATCON) stopped working and, most of all, there was absolutely no idling of the KLH10 host CPU. We discovered that probably MONGEN only compiles some macro configuration files and then relinks the monitor using a prebuilt TOPS10.REL, made up from many macro files, including CLOCK1.MAC. So we need to entirely rebuild TOPS10.REL from sources, but we do not know ho to do that. The Software Installation Guide directs to Appendix B where it is suggested that, for more information about building the monitor library file (i.e. TOPS10.REL), we should read the batch control file COMPIL.CTL. Unfortunately COMPIL.CTL does NOT contain any comment or explanation. We think it is intended for somebody with a previous somewhat deep knowledge about such tasks, which we do not actually have. we are using a quite standard installation so common defaults should be fine, but there are anyway lots of totally obscure files to customize (BUILDS.MIC, BUILDS.PTH, GEN.MIC, ...). Any help, suggestion or pointer would be much appreciated! G. (http://decnet.ipv7.net)

What use are *you* making of HECnet?

by sampsa＠mac.com

For anyone who might be interested: I've done a tiny modification to the TETRIS game on CHIMPY, the keys are now more sensible if you don't like using a numeric keypad (I'm mostly on my Macbook Pro so I don't). So If you're bored and fancy a game of tetris, log in to CHIMPY as TETRIS and have at it. I might even send out some type of award to the high scorer of the year should there be significant take up :) Sampsa On 2 Mar 2009, at 08:12, Sampsa Laine wrote: Done.

LEGATO used to relay email between HECnet (using MAIL11) and the Internet/SMTP, but I quit doing that last fall when I switched registrars. There's no reason I couldn't - I just never bothered to set up the necessary domain name and mail routing again. It was pretty much never used, even by me - after all, everyone with a HECnet connection already has an Internet connection. Bob We could talk "SMTP" over DECnet..... -P

How do you connect to HECnet?

by marc＠bluevine.net

My system (DUSTY) is a SIMH VAX running on Linux (ubuntu JeOS) under an ESXi hypervisor. I've given the Linux system two NICs (that's easy in ESXi), one for Linux, and one dedicated to the VAX. For my purposes, I also have the VAX's interface set up on a VLAN to move it onto a separate virtual network for my "trailing edge" systems. The VAX speaks DECnet-over-MultiNet to LEGATO. Yes, the Multinet link provides a second connection into HECnet, Christine and I have been the sites routing between the two types of connections. There were also one or two people using Cisco router links as well, but I don't know if anyone still has those links up. Do we need any additional such routing points? Now that I have an ESXi system, it's trivial for me to add another small virtual machine that could act as such a bridge. --Marc

How do you connect to HECnet?

My NetBSD machine runs the two NIC's so that I *can* keep DECnet apart from IP. I have dedicated LAN's for each protocol here. Overkill??? Absolutely! It allows me to duplicate the multiple environments that I may encounter during the course of things. It sure does make it easier when debugging a network problem/outage. The VAXen have only one NIC and as such run only DECnet (and of course SCS traffic). IP is relegated to other machines/hardware/paths. It does take more hardware but in the end it is VERY clean. The Alpha's, on the other hand, have multiple NIC's - one for IP, one for DECnet, and one other. -Steve From: owner-hecnet at Update.UU.SE [mailto:owner-hecnet at Update.UU.SE] On Behalf Of Sampsa Laine Sent: Monday, March 02, 2009 09:16 To: hecnet at Update.UU.SE Subject: Re: [HECnet] How do you connect to HECnet? Weirdly enough, I have no problem with running the bridge and SIMH on the same machine - caveat: I am running on OS X. At the moment, I have the following: - Gorilla (OS X 10.4.something) running the bridge on interface 0 - GORVAX (SIMH, OpenVMS 7.3, MULTINET) running on interface 0, acting as a router between the bridge and a MULTINET tunnel to the outside - CHIMPY (running VMS 8.3, TCP/IP services), acting as an end node on the bridged network So on the main host, there's only one interface and it all works (all = DECNET, I can't get IP traffic from Gorilla to GORVAX).

Or have I still misunderstood? You're making things over-complex. I can't ever imagine a scenario in which you need more than two interfaces. In your first example above, 1 and 2 can be on the same interface with no problems. The only time you even need more than one interface is if the machine running the bridge program is itself also a DECnet node, in which case the machines own DECnet traffic can't be on the same interface as the bridge is capturing DECnet traffic. All other stuff can be shared on any of the interfaces. In short. bridge can coexist with any TCP/IP traffic. DECnet can coexist with any TCP/IP traffic. bridge and DECnet can't coexist. And in all of these sentences I'm talking about that specific machines protocols/applications running. It is not relevant if another machine talks DECnet when we're talking about the bridge program. The bridge program is not a DECnet program, and should not be confused with them. The bridge is just a cable extension. A repeater. A hub. Johnny
