Hello list,
Some months ago I asked for help regarding one of my Vaxstation 4000,
whose power supply appeared to be dead. I have finally found the time
(and the mood) to take apart the PS from the machine and open it to take
a look. I have got to vandalize it a little bit, since one of the screws
was completely stuck in place... nothing that a creative use of a dremel
tool can' fix ;)
What I have found is one of the two big fuses near the mains connection
is blown. This _should_ be good news, since all what I have to do is to
find a compatible fuse. But I wonder what will I find when I replace it.
There is nothing obviously burnt in the PS. The big capacitors look good
(even shiny, once I've blown off the dust), and there is no funny smell
at all.
So, my next step will be to replace the thing and see if it blows up again.
Just a question for the repair savvy... is it safe to power up the PS
outside of the vaxstation?
I'll tell you how the thing evolves :)
regards,
Just thought I'd mention from yesterdays conversation. It loks like for linux there maybe some kernel update rpms for using decnet with linux. This is something I'm interested in. IDK about anyone else.

Can I take my copy of VMS which does not have installed phave iv or decnet plus and load one of them to use these commands? They weren't there earlier today but I don't have networking installed with VMS.

@sys$manager:netconfig // is involved.

Hi Steve,
I'll be going as I reside around the corner from InfoAge. I'll can lend you
& VCF a hand with anything DEC & VMS.

I speak to machines with the voice of humanity.
I've got a 2620 and an 861 which anyone can have for the cost of shipping.

Well, between the two of you decide who wants the 1841 and who wants the 1811w. :)

Just wanted to let people know that I have ported my user mode router on to
VAXELN, running on an rtVAX 1000 (KA620), and it is up on HECnet.
There are some compromises, and it is pretty slow at the moment, with
adjacencies dropping from time to time, but if you see a router at 5.30 then
it is VAXELN.
Right now it is running on the real hardware, but as that is noisy and uses
155W of power then it won't be around very often. For development purposes I
also run it on SIMH where it is a bit quicker, but that will also be
intermittent. The machine is diskless and has only one Ethernet adapter, so
it is running raw packets on the LAN and talking to Johnny's bridge using
UDP, it is acting as my router to HECnet. You should be able to reach nodes
at 5.11, 5.99 and 5.100, but it *will* be slow.
Next steps will be to make it more efficient.
Regards
Rob
Guys,
Just saw this, I'm going to buy in instance tonight and see if I can get SIMH to run on it (and ideally maybe the bridge)..

PS: I've nothing to do with the company, just thought it might be a interesting platform to play on, especially if it comes with a static IP..
Sorry for making a new announcement so close after the previous one, and
the changes are not so great, but I think they are important enough to
send this out right away.
The only thing this release addresses is DECnet over IP:
. First of all, you can now also run DECnet over IP using TCP.
The DECnet over IP implementation have been tested a lot in the last few
days, and some things in the VMS Multinet protocol was not so well
understood by me, and the code did not work very reliably against VMS
for that reason. With the help of Bob Armstrong I've rewritten this code
now, to behave more like VMS does, and my initial testing indicates that
it now works the way it should.
So I'd recommend anyone who is using this feature to upgrade to the
latest version right away.
As usual, the distribution is available from:
ftp://mim.update.uu.se/bqtcp.dsk
ftp://mim.update.uu.se/bqtcp.tap
ftp://ftp.update.uu.se/pub/pdp11/rsx/tcpip/tcpip.dsk
The documentation is also available through ftp on Mim, or also at
http://mim.update.uu.se/tcpipdoc
Note! I've realized that BQTCP/IP do not work right if you have a
PDP-11/74 with multiple processors online. I'll fix that at some point,
as it's probably just a case of affinity not being set on devices, nor
relevant processes. This might only be a problem with telnet in fact. I
know for sure that the IP and TCP drivers works ok in multiprocessor
systems.
