I occasionally think about getting some kind of Itanium to run VMS on. I
know zero about these machine, what models would people suggest that I might
be able to buy at hobbyist prices?

Rob

Itanium machines do demand a LOT of RAM. I can only assume the
assembly language/machine code is very inefficient ;)
but then I dug into a scrap pile of HP blades (BL20p) and found memory
which had the same parameters as a zx6000/rx2600 needs. Decided to test
and to my big surprise I found out that the blade memory worked in the
zx6000. Now I have enough memory.
Yeah, a lot of HP gear of the same era uses the RAM
This is more like a nice to know post for everybody.
Indeed. I more wanted to let folks know I can provide the spares on a sale
or
trade basis at community pricing (i.e. cheap) as they are still very
expensive
from most sources.

If anyone has a HP Integrity zx6000, rx2600 or a similar machine that takes DDR2100 Registered ECC RAM I have 2x spare pairs of 2GB RAM sticks available pulled fresh working from my zx6000.
I also have a 1.3GHz/3MB cache CPU module that I might be persuaded to part with.
This is more an FYI than a 'I must get rid of these for cash now' - I figured a few people were running Integrity machines and might want he parts.
I took mine down to 1 CPU and 8GB of RAM to cut down the power consumption and heat output (it's down from 480W to 200W at idle now :) ).
Now to install VMS 8.4 on it!

With my connection, I noticed that the circuit would disconnect and reconnect periodically. It corresponded to the timeout in my firewall causing the UDP association to be lost. When I increased the timeout in my firewall for these port 700 UDP "connections", that made my circuit much more stable.
Unfortunately, my firewall (a SonicWALL NSA 240) is also stupid in that it *must* randomize the source port for outgoing packets, so I'm not able to connect to HECnet because MultiNet insists that the source port must also be 700 and mine are coming through with random port numbers.

1) Defining the permanent node database for both TOPS10 and TOPS20. NCP
rejects the DEFINE NODE commands. I guess there is some sort of utility
like the one in RSX (CFE) to define the "permanent" node list, but I've
not been able to find that one. There is a NIPGEN in TOPS-10 to build a
CMD file with the SET NODE commands, but no NIPGEN in TOPS-20 that I've
been able to find...
T10/T20 has no permanent database, nor does it understand copy, look
for a program named nodnam.exe it reads ini:NODNAM.INI and populated the
node-name-table..
And nodnam.ini looks like this...

I've found NODNAM in both TOPS10 and TOPS20... Now I'll try to find where to hook it so its get executed on system startup.
define node 1.42 name BIGBOA
define node 1.100 name FLETCH
define node 1.150 name GLGMSH
Hmmm time to code a little program to parse the output of SHOW KNOWN NODES and build this file :)
Here's what's on SOL..

Do you know what is the equivalent file for TOPS-10? Is that SYSJOB.INI?

Understood.
Now I've got another problem. The TOPS-10 node goes yo-yo:

Message from user DECNET on BITXOV
DECnet event 4.18, adjacency down
I see these message about every 20 minutes from random nodes. The error
message is almost always:
"Unexpected packet type"
So where do we go from here?

You can always turn off logging if it bothers you :-)
Bob,
If someone trying to use the link, they will be unhappy..

I agree. If something is telling you that there is a problem,
you should fix the problem, not silence the information.

2) LAT. LAT works fine in TOPS-20. In TOPS-10 LCP tells me LAT is
active, but it does not work (does not even announce itself). How do I
enable LAT in TOPS-10?
Don't knew.
3) And, spealking of LAT... How do I change the service identification
in TOPS-20?
What do you mean with service identification? The stuff in "sh exec
char?"
I mean, how do I change it PERMANENTLY? I guess I have to
put it in some sort of auto-executing file. SYSTEM.CMD? Something in
7-1-CONFIG.CMD? Again, any pointer to docs would be very appreciated. I
don't want to bug you with the thousands of questions I've got :)

There is nothing permanent, unless you poke it in to the monitr.exe
