If I remember right Multinet caches the IP address and does not flush it. Let's not forget that Process Software does not support anything but a reboot!
It is not that big a hit. In the future the hit will be even less when I make some changes to the startups and the hardware.
So far I have not heard of any complaints when it reboots. I suspect that no one even notices... It really does amount to noise.

I have written a DCL procedure that does IP address lookups at
predetermined (configurable) intervals. If it finds a mismatched IP
address it reconfigures the the TCP-0-n (where "n" is the area - in my
case) IP address and schedules a reboot.
To avoid reboot, did you try
$ ncp set circ TCP-0-n sta off
$ multinet set/decnet/remote=new_IP_addr/device=TCPAn:/connect
$ ncp set circuit TCP-0-n state on cost 9 hello timer 300
These commands execute without error. I have no means yet to test
if remote address gets really changed.

You've seen _Dark Star_ ?? The first time I talked to a DSSI drive, that
image of having an existential conversation with the smart bomb kept popping
into my head :-) Too bad the RFxx firmware guys couldn't find a way to
stick Eliza in there somehow....

DSSI is just plain neat. If I remember correctly the drives themselves speak enough MSCP to service cluster requests themselves.

What's wrong with DSSI? I've got a uVAX-III with a farm of DSSI drives
(the DEC R-400X box) in the garage. DSSI drives are cool - T11 CPUs in each
one, running RSX-11S (Johnny should love that!). They even have a little
MCR that you can talk to...
BTW, if anybody has a DSSI DLT drive (e.g. a TFxx) that they're willing to

How is IO on the cf card?
I haven't attempted to benchmark it, but empirically it works OK. The
system runs Ubuntu 10.04LTS with a custom kernel (the eBox has some
non-standard hardware that's not supported by the default kernel) and
simh-vax, and that's about all. I have the VAX emulation throttled to
about 50% of the CPU, so I could run another emulator if I felt like it. I
wanted to run TOPS-20 on it, but the idle detection in simh-KS10 for TOPS20
doesn't appear to work, so it hogs all the CPU time.
What I'd like to do with LEGATO is to set up two simulated NI devices in
simh. One will be my real Ethernet, and the other will be a virtual bridge
to Johnny's world. There appear to be enough pieces to do that, but I
haven't gotten around to trying it yet.

I've heard that before. :)
To that end I've been typing DIA0: all day long when I meant DUA0: on the simh machine we've been working on. :)

I've got 4x VLC motherboards. I should really rig up some power for

How is IO on the cf card? I've got a system here that might turn into a

I forgot to add...
DEC used area 13 for DECUS (at least US anyway). The DECUS nodes were
colors just like our area 32. The area would be used for "special"
events and would be connected to the easynet backbone during a DECUS
symposium. Mostly this would occur in spring and fall. If the
documentation did not refer to area 13 for DECserver management, I would
have suggested area 13 for out special events area top pay homage to
that wonderful organization. Mark Wickens was going to use it for the
DEC legacy event this past October. I don't remember if he wound up
using it or used his own (area 4). Your list mentions me as the
"owner". That's fine, but I more of a coordinator of that area. Anyone
can use it for a "special" event like what Mark has - just let me know.

Could you point me to some of that documentation? I've not seen any of
it, and I don't really at all understand the point of even setting up
information in the nodename database for DECservers, which don't even
speak DECnet to begin with. (And I do have DECservers up and running, as
well as manuals...)
I know that, from a convenience point of view, you can use the name as a
short cut for specifying the MAC address and circuit, but having an area
reserved for such a simple detail seems excessive.
Second SG1 is a VS4000/30 (VLC). It is small, quiet, and cheap to run
-
all very important features. If I remember correctly, LEGATO is the
same platform for the exact purpose. The only difference between my
Multnet "gateway" is that it can accommodate dynamic-DNS at the other
end.
Cool. I guess that platform should be enough to handle normal HECnet
traffic even if we grow some more.
How do you deal with dynamic IP addresses?
PS One more network is in the wings. You should be getting email
about
it soon enough if you have not already.
Nothing yet.

That is 14 areas, and I'm talking to one more guy who wants a new

which would bring us to 15.
Anyone object to me giving him area 13? It was asked to be reserved
for
DECserver management, but I don't really see the point of having an
area
for that purpose. But if you can convince me... :-)
Also, SG1:: is quite a hub from the bridge point of view. Lots of
connections coming through there. Nice. :-) What type of machine is
it?
