Guys,
I'm following the procedure in the Cluster manual, pp10-9, to configure a VAX satellite from an alpha boot node, and I'm getting a system crash.
My question is whether I need to run this procedure with the Alpha in standalone mode, or whether this is a situation requiring a patch, or whether I can get away with something different.
This is the first part of the procedure to enable the MOP server.
The second part is to configure the MOP service for the VAX satellite.
The Alpha is running OpenVMS 8.3
Thanks for the help, Mark.
The log is:
$$ mcr ncp
NCP>define circuit ewa-0 service enabled state on

Johnny,
Thanks for the update. Will you be around on the weekend 8/9th Oct to
update your end with an IP address?
If possible could we try and update tonight or tomorrow night - I have
bought 3G access for three days, so it would be useful to see if it all
hangs together before the big day.
Is there any diagnostics I can run to check whether the bridge is
connected at this end?
Can you check the state of the bridge at your end - I cant currently see
hecnet from my end - I've looked at the setup but can't see any reason why
it shouldn't be working
Thanks, Mark.

The 3G dongle has a different P address and probably in another

You wrote that you added a dongle. How does the router now know to use
that as its iway to the internet in stead of the wired way? I.e. How
is its default route configured?
Yes, the router uses the 3G dongle as a substitute to the ADSL
connection if it is dropped (or removed). The whole set up of the router
remains the same, but clearly the IP address that the router presents
itself to the internet is different, as are the nameservers.
DHCP is served by a different box, so that remains unaffected.
For the most part it works beautifully.
You have two "issues".
First of all, telnet is not a useful tool to test anything here, since telnet uses tcp, while the bridge uses udp.
Second, your connection through the dongle is not accepted by Update, since the bridge program knows the remote IP address, and do not accept packets from random nodes on the internet. So you need to let me know what IP address you have, so that I can put that in my bridge config file.

I forget, does the bridge use tcp or udp?
Does the bridge program tell you anything?

If I manually try and telnet to psilo.update.uu.se port 4711 I get a network is unreachable. If I ping the same address the ping gets through.
Is this something to do with a restriction on port numbers? Is there anything we can do about this, or try?

for experimental purposes.
I think I understand how to setup my 3G dongle to connect to the
internet via an ubuntu machine. I am happy setting up a DHCP and DNS
server on the same machine. The bit I don't understand is how I would
fit the hecnet bridge into this network. Normally on my DSL router I
have a port redirection rule setup on port 4711 to point to a Debian
based box on my LAN.
How would I achieve the same effect on a linux box? If I run the bridge
on the same box, does this negate the need for a rule?
If all this works, is there a restriction of one decnet area per lan
segment? Can I run two areas on my side of the bridge?
Thanks for the help, Mark
In general, if/when you have a setup like that, it's the same as if you connect your computer directly to the internet. So, your Linux box is at the same location your DSL router is. So, there are no rules to setup to pass a packet through the router. The reason for the rule is that your DSL router acts as a firewall (and possibly NAT), which is what you need to circumvent for the bridge. No firewall/NAT box in between means no need to punch a hole through it.
So you should be able to run the bridge directly on that box, and it should work. All however, also depends on what your mobile operator might be doing...
Area number for experimental is probably not going to help you, though. You already have an area. Adding more nodes to it is hardly any different than having a new area setup, except that if you setup a new area, you will need an area router for it. I don't really see much point in the "experimental" area we have reserved, but since we have plenty of areas anyway, there is no harm in it. Anyone using that area can expect things to not work though, as someone else might also be using the same area, and conflict/confusion might follow.
As for having several different areas on the same lan, no problem.

Open the box and doisconnect the powersupply wires. Measure voltages at the connectors, start with the disk power outlets since these voltages are known.
HP has maintenance manuals on-line for some systems, check that.

Chimpy wont boot for some reason anymore.

Any ideas?

try leaving it alone, unplugged for a week, it may not work in your
case but who knows
it happened to me only once in life, but I had a dead machine
resurrecting by itself a week later
without doing absolutely nothing, I still don't know what happened
that box worked for twenty years "after" the problem
Also on a VAX, I had a dead machine that started working again
but this one had lights, just needed to recharge something
before it would start running tests again
this box had been unplugged for too many years
sometimes a bad battery pack does also some strange things
cheers

Hello!
Checked the power supply? It might have blown the fuses/circuit
breakers on it. What was it doing before it unceremoniously shut
itself down?

Hello!
It most certainly could be. Is that fellow the oldest in your
collection or the youngest? Remember computers age faster then people,
but not faster then cats. (We will leave out the other entity here,
and of course why.)
