Greetings,
I noticed this before the move - when I go to the nodename database lookup page, I get a few lines and then MIM doesn't respond to anything after that.
It doesn't appear to serve any more pages. I assume that the webserver has crashed.
I'm not sure how long this has been happening for. I was trying to check if a new node had been added to the list.
Cheers, Wiz!!
MIM move is now underways. The old Mim is up, but be aware that I've
already taken a snapshot of the disks now, which are being transferred.
So anything changed on Mim after this time will not carry over to new Mim.
The transfer will take a number of hours, but I'll let people know once
new Mim is up and running.
Johnny

My pyDECNET router THEARK runs on a Pi Zero W2. Normally all happy and peachy for months on end but from time to time it loses connection to its area router. I started with a simple script that checked the connection from time to time and sent an email. Well now this has grown to a full blown thing with many capabilities so I decided to bring this to the group. I dropped it on GitHub today mkostersitz/hecnet-daemon<https://github.com/mkostersitz/hecnet-daemon>. Take a look and let me know what you think. Hope it is helpful to some

I've had alot of progress with HECnet connection, I created another VM
to run linux and pydecnet then proceeded to activate the connection to
HECnet. It all works very well and I have full functioning access. Hit
me up with email to GUARD::MBROWN
There is only one problem I have left, how do I enter the details in
NODENAMES.DAT into the local name lookup. This will be one of those
Phase V problems as previousely griped about. Phase V uses mcr
decnet_register to enter host names and I have done that for a handfull
of commonly used hosts, but I have no Idea how I could do this with the
nodenames.dat file.
I wonder how you yourselves do this with Phase 4, I might be able to get
a clue if I knew how you did this trick in the first place.
Thank You.
It looks like I need some new connections to HECnet, as my existing ones are down. Is there anyone in the US, especially the Pacific Northwest able to setup a Multinet connection? One in Europe as well would be good.
Unfortunately I’m one of the people having trouble to Johnny.

I've downloaded copies of pyDECnet from two places:
1: svn://akdesign.dyndns.org/pydecnet/trunk/pydecnet (using svn)
2: http://akdesign.dyndns.org:8080/resources/public/index.html
The current version of code at the svn is revision 653.
The current version of the package is V1.1.0-rc2
Is there a difference between the two?
Which is the best source for pyDECnet?
Also, does anyone have any configuration samples they might care to share. I have a working one but I think I am lacking in creativity to make the most out of pyDECnet.
And while I'm at it, is Supratim's pyDECnet monitor page custom? Because it sure doesn't look a lot like mine. But I wouldn't be surprised that his is or that I messed something up on mine.

I installed DECnet+ when I was setting up because it claimed being able
to do DECnet over TCP.
By poking around with net$configure I found I could get my machines to
talk DECnet over TCPÂ and I can do all the net related commands. So I
figured it must be very close to being able to connect to HECnet.
I wondered if it is possible to connect to HECnet using DECnet+, and how
that might be done ?
[Re-sending as there's an unfortunate interaction between mailing
lists and my multiple email addresses, so this didn't make it to the
list.]

FYI,
I'm beta-testing Multinet 6.0 for VAX, Alpha, IA64 and x86, which still has the DECnet over TCP feature.
If Process Software continues to offer a hobbyist licence, that'll be another way of connecting into DECnet for x86 VMS.
Looking good so far. The terrors of SSHD are for this coming weekend.

You just need to peer with someone else with DECnet+, which aren't that many...

Last week I discovered that the power supply for PDXVAX had died (VAXstation 4000 m60). I swapped that system out with my spare, and then set about a project I’d been planning for years, so the hardware is now virtual, and won’t need to be shutdown when the weather is too hot. When I booted it temporarily on the other VAXstation I discovered that it looks like I probably need to update my Multinet links. All three connections appear to be down.
I know I was connecting to A2RTR, MIM, and one other.
DECNET-CONFIG>show

Any help getting back online would be appreciated. Hopefully this is just a case of IP addresses having changed over the last 4 years.
