Right now I have datalink (Ethernet, SIMH DMC11 emulation, Multinet over UDP), Routing (Phase IV endnode, L1 router, L2 router, over both datalink types), MOP (Ethernet only, including console carrier), primitive monitoring via HTTP, and about 3% of NSP.

Although I do have enough of NSP and NICE to allow SH KNOWN CIRCUIT and SH ADJACENT NODES. Regards Rob

Are events logged on either node when the packets are dropped? What does Wireshark say is in the packet headers? What does the VAX say in "show node tops10 status" ? paul

Oh cool, was just thinking about writing stuff in Python for DECNET. Let me know when the stack is stable. The routing part looks pretty good right now. I don't have it active all the time yet, but I hooked it into Multinet and it appeared to be stable. The main issue is that point to point DECnet over UDP is architecturally invalid; the initialization state machine isn't designed for that. The result is that it takes a while for both sides to agree that the circuit is "Up". I've been thinking of workaround for the misbehavior. A cleaner solution is to run Multinet over TCP, which appears to exist -- if someone can figure out how to do that and what the packet formats look like for that case, I'll implement it. Alternatively, the SIMH DMC11 protocol works very well, it would clearly be a superior solution for Hecnet. paul

HECnet LAT groups...

Don't forget about MIM::DU4:[DECNET]LATGROUPS.TXT -Steve -----Original Message----- From: owner-hecnet at Update.UU.SE [mailto:owner-hecnet at Update.UU.SE] On Behalf Of Johnny Billquist Sent: Thursday, May 16, 2013 10:12 To: hecnet Subject: [HECnet] HECnet LAT groups... Hi. I'd like to ask people to look over their LAT setups. Looking at group 0 right now, the list is rather long, and containing lots of services that looks like they really would be better placed in some other group. The idea of group 0 has been to have publicly available systems in group 0, so that people using DECservers can just look at group 0, and whatever local groups they have, and not have a long list of services that are of no relevance at all to them.
