Steve,
As discussed on the list, the problem was with SIMH on Snow Leopard specifically and Johnny seems to have fixed whatever it was. Thanks for the offer though.

My only task this weekend is dealing with the snow on the driveway. So far we have had 5+ inches. They expect another 5-7 more. The snow blower went through this last pass in 90 minutes.

It's not a VMS issue per se I think - something to do with SIMH and the network interface. I might have a play later.

I've replaced the server that ran my bridge and GORVAX, unfortunately there's something REALLY broken with GORVAX that I just can't figure out right now (and don't really have the time to, either). Anyway, RHESUS and CHIMPY are up, CHIMP should be up RSN. GORVAX will be down for a little while longer, as will the Fidonet mail gateway. Sampsa
That would be very useful, care to elaborate on what the problem was, and/or link me to your fixed source/binaries?
BTW, I've noticed that binaries are wonderfully portable across OS X systems, for example, when I recompiled your bridge on Snow Leopard with the latest Xcode, it kept stack dumping. However the binary compiled on Tiger Server works fine and doesn't have any problems.

Maybe I can help. I just fixed a "problem" or two in simh, which

Contact me off list to investigate this further...

I'm not having much luck looking for newer ones. It may be possible to
reverse engineer the differences from the implementation source code, if
available. I looked a bit at DECnet/E but it's not easily to parse...
Keep in mind the DECnet version handling and reserved field rules.
When mixed versions communicate, both sides report their version and the
higher version system is then responsible for speaking in a way that the
older system will understand.
"Reserved" means "send zero, ignore on receipt". It most definitely
does NOT mean "check on receive that this is zero", that's a silly
mistake all too often make in protocol design. This too is for mixed
version handling. If a new flag can safely be ignored by an older
system, then the newer system can simply send that flag in what used to
be a reserved field, and the right thing happens.
Finally, proxy was originally a VMS specific enhancement and was adopted
in some other implementations (I know DECnet/E picked it up, at least in
a semi-compatible form). I'm not sure that it was ever specified in an
architecture spec.

Subject: [HECnet] DECnet session control specification
Hello everyone!
During the last week or so I've spent many hours studying some DECnet
traffic because I was willing to better understand its inner working.
Well, I've discovered that the session control specification commonly
available on the Internet (V1.0) is not the latest, and it seems that
another newer version is not readily available.
While other DECnet protocols such as DRP and NSP appear to be current
(and
in facts their description matches actual data captured from the
Ethernet),
the SCP is obviously different both in formal definition and in
practice.
For example, the specification states that for V1.0 the version field
should
be 000 binary, but VMS sets it to 001 and a bit field that should be
reserved for future use and always set to zero has actually a meaning
(at
least one bit seems to be used to signal proxy access requests).
So the question is: does anyone here has a copy of a newer session
control
specification or at least knows which are the the differences between
V1.0
and the following (V1.1?) version?
Thank you very much,
G.

Isn't Personal Alpha a version of the Charon-AXP emulator? I've never
used Personal Alpha, but I am using the free version of Charon-AXP and I can
tell you that, unlike simh, it has no OpenVMS idle detection. Charon will
always use 100% of whatever CPU(s) it's running on, regardless of what the
emulated system is doing. That makes it difficult to run Charon
concurrently with other simulators unless you can afford to dedicate
separate CPUs to each one.

... and significantly bumps up your electricity bill to boot.
How does it perform on something like an Atom processor? I've been thinking about building a system with an Atom 330 CPU for SIMH, KLH10 and E11.

Wow that sounds... odd. Check your CPU affinity, for the exe's.... It almost sounds like something deadlocking on the libpcap.........?
I'm just guessing, I'll have to fire up personal alpha & simh to take a looksee.

I just started Multinet, so the link is back up.
Now we have PDXVAX and MISER up, but we're still missing PETEY and ZARQON
(and of course the poor GORVAX, but that's expected).
Bob
Hi everyone,
Hopefully a few people will read this. But it's not very exciting, My
machine is back up again. I had tried it a few times but the multinet
link was down.
I forgot to mention that Petey is dead PSU has gone, I am using a simh
machine to replace it at the moment. It is called slimer.
The main reason it's down is because I have been using another machine
with Personal Alpha to try and netboot a Dell Itanium machine. I have
not had much success so far, but I am still trying.
Anyway it seems that whenever I run Personal Alpha any Simh machines I

And GORVAX is off to the land of the borken for now, in Amsterdam myself so unable to dedicate too much time to fixing it.

That is helpful! At least I know you're OK. I lost the link, then my IP changed, and I couldn't trace to charon ... a perfect storm of sorts.
Meanwhile, it's snowing here in Ohio.

Well, it was an iMac and the only other things stolen were a few laptops that were fairly recent so I'm sure they're fenceable for some decent money pretty quickly.
I think these guys were pros, they left no mess or anything so all in all I'm pleased with the service.
