As Johnny knows I've been experiencing some configuration issues since installing Ubuntu 14.04 on the server that hosts the SIMH instance that is SIMVAX. I attempted a Kubuntu upgrade but that failed so I had no resort other than to backup the existing root partition and re-install from scratch.
I've been unable to configure the networking correctly since the re-install. The symptom is adjacency up and down messages, coming in consecutively every minute or so. I've tried numerous combinations of configuration that have not solved the connectivity issues. When adjacency is up I'm able to DIR MIM:: successfully.

%<----------%<---------%<----------
I upgraded to SIMH master on the suggesting of Mark Pizolatto when I wrote the SIMH mailing list with an autoboot failure issue that I've had for as long as I remember (that turned out to be because I was using an old kernel ROM image).
My networking configuration on the HP Microserver is as follows:
2 x 1000MB Network Cards
eth2 - The internal card is dedicated to Ubuntu and configured statically at 192.168.1.126 via ifconfig (I uninstalled NetworkManager because I have no need for dynamic configuration).
eth3 - A PCI express card that is not configured for Ubuntu. It is brought up on the understanding that SIMH will provide the necessary configuration.
My /etc/network/interfaces is as follows:
%<----------%<---------%<----------
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback
iface eth2 inet static
address 192.168.1.126
netmask 255.255.255.0
gateway 192.168.1.2
dns-nameservers 192.168.1.2
dns-search hecnet.eu
%<----------%<---------%<----------
My /etc/rc.local script brings up the interfaces:
%<----------%<---------%<----------
# Enable the first network interface for linux use
ifconfig eth2 up
# Bring up the second network interface it's for SIMH use - it is not configured
ifconfig eth3 up
/bin/bash /usr/local/bridge/bridge.sh
/bin/bash /usr/local/vax/vax.sh
%<----------%<---------%<----------
As you can see it is also responsible for bringing up Johnny's bridge and the SIMH instance.
After configuration the networking looks like this:
%<----------%<---------%<----------
msw at hpm:/usr/local/bridge$ ifconfig -a

The SIMH vax.ini script contains the following. You can see that xq is defined as eth1 which in SIMH parlance is the 2nd ethernet interface and from the start-up trace it can be seen that the correct network interface, eth3, is being picked up and used.

Message from user DECNET on SIMVAX
DECnet event 4.18, adjacency down
Hey all,
1). What are the switches for on the halt/run switch board in the BA400? Are they covered in the manual?
2). Is the TOD chip by chance on that board, or have I managed to disable it when the boot mode selector switch broke making it impossible to turn?
(I removed the halt/run switch board as HALT was permanently on and I do not know why. I think the switch is shot.)
A busted TOD would certainly explain why VMS can't boot, why Ultrix machine checks...but not why NetBSD and OpenBSD boot fine.

Yeah I've noticed that too. I think it sometimes drifts 3 hours due to a KVM/QEMU timekeeping thing with FreeBSD.

It's 4. I have it sitting in a Q/CD as IIRC all my DHV11s are configured to sit happily in a Q/CD slot.
The error you got from moving the DELQA, in combination with how I think I should read your illustration of card locations would suggest that it's 4 Q-CD slots.
Yup.
But all this is very hard to debug remotely like this. I would try removing the DHV11 in order to minimize the components in the system that can create problems. That also means moving the DELQA up to the DHV11 location. It should definitely be on the left side in that case.
I added the DHV11 as I thought it was causing issues...that I think were actually related to misconfigure hosts file.
Do I need a continuity card in the CD slot of the Q/CD or no? Can never remember the rules on those damn things.

Hum. Hard to say for sure, but this might be a classical case of you having the NIC in the wrong place. Move it over to the "E" side...

I wouldn't be too concerned about this detail, but if you want to worry about it, see if you can get a different output when running under SIMH.
Alright.
FYI: This is Ultrix 4.0. It appears to stop at printing what the time has been set
to.
I don't recall what the sequence of output produced at boot time is (maybe you capture that and tell us), but one thing to look at would be proper sequencing of the Qbus bus grants. What type of chassis/backplane are you using and what devices are plugged into the bus and what slots are they in??
