Mark. One short observation. You are setting the mac address of the interface used by simh to some random value. Have you tried setting it to the value that DECnet later expects to actually set it to, to see if that makes it any better?

Subject: [HECnet] Ubuntu 14.04 SIMH Network Woes
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

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:

As an addendum I fired up the RX2660 server running OpenVMS 8.4.
This is TSR2 on 4.12.
There are no adjacency up messages for this box and the bridge doesn't
seem to communicate with it (no debugging generated).
I can directory the remote FAL server directory and SET HOST between the
two boxes which are on the same LAN - but I cannot see MIM:: from TSR2,
only from SIMVAX:: when the adjacencies are up.
I assume the bridge is listening on that same LAN? If so, this sounds weird.
However, unless it's an area router, you might hit into problems there too...
Johnny
Phew! :-)
In that case I would suggest doing some packet sniffing and seeing if packets are getting dropped. There are "keep alive" packets called Ethernet Hello that get sent out every 15 seconds, if some of those get missed for any reason then it can have this effect.

Message from user DECNET on SIMVAX
DECnet event 4.18, adjacency down
That is my user mode router, it may not be a problem on your side. I am not at home to investigate. Is anyone else getting failures from area 5?

Subject: [HECnet] Ubuntu 14.04 SIMH Network Woes
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:

Message from user DECNET on SIMVAX
DECnet event 4.18, adjacency down
Hello!
Mark this is an early morning (for here) out of the blue guess, but
could it be something not quite right on your router?
As for your Ubuntu issues..... It might even be that distribution.
That family can be extremely hard to configure for applications that
aren't normally part of their own packaging....
