There are now some updates/bug fixes. For instance it can now handle
HECnet bridge packets (hopefully).

Hi,
I have a TCP (via multinet) connection to IMPVAX which is hardly ever down. It is at the moment.
Anybody else willing to give me some links to other areas?
Regards,
Keith

The packet in question is an init packet, used to start up a link.
If tcpdump knew about this, it would look somewhat like:
Init, 1.13 info 01 size 576 ver 2/0/0 timer 300
Why MIM decided to restart the link is another question.

Don't let the ANF part of the name fool you! It can do the following:
* listen for ethernet frames with ANF-10, DECnet and LAT.
* listen for DDCMP (simh-style over TCP or UDP), with decoding
of payload (ANF-10 or DECnet).
* listen for Multinet over TCP, with decoding of DECnet.
* do several of the above, in parallel, if you want to see how
a box in the middle molests your data.
* read (and write) pcap-format files.
As usual this is a work-in-progress, and some things (like the manual)
are missing, but the code mostly works. Use the -h flag for help at
this time.

Johnny,
I am suddenly seeing this from IMPVAX. Not sure what to make of this ?

WWENG2.SYS? Is that right for the DS-550?

I speak to machines with the voice of humanity.
Does anyone have the Phase II DECnet that goes with RSTS V7.0? I think it calls itself DECnet/E V1.1, rather confusingly.
For that matter, are there any Phase II DECnet releases around? I know of the TOPS-20 one; any others? Ditto for Phase III.

Hey folks. I'm looking for firmware for the DECserver-550, which gets
downloaded into the terminal server by its boot host. Does anyone here
have a copy? (It seems I have the firmware for every DECserver except
that..)
Thanks,

I posted this message yesterday, but for some reason people are telling me
it never went to the list.
I removed the photos I originally attached and am sending it again.

Subject: Re: [HECnet] Sunlink DNA
To: hecnet at update.uu.se
To everyone who asked, I built TME last night on Ubuntu 18.04 on two
different systems, and installed NetBSD 1.6.2 on a sun3/160 instance.
It's working very nicely, minus networking; bear in mind that TME was
originally written to run on a NetBSD host (it's in the pkg collection),
and makes use of BPF to implement networking (I seem to remember it also
working on FreeBSD). Linux does have a bpf compatibility interface, so I'll
see if it can be made to work and follow up with you all. That said, grab
TME here: https://people.csail.mit.edu/fredette/tme/tme-0.8.tar.gz
That's the home site, there's lots of info on the emulator
https://people.csail.mit.edu/fredette/tme/
There's also this site, specifically about installing SunOS 4.1.1:
http://www.abiyo.net/retrocomputing/installingsunos41
1tosun3emulatedintme08onlinux
DON'T follow those build instructions, they're incredibly old and will get
you nowhere fast. :)
Here are my steps:
Make sure you have the gtk-2.0 and glib2.0 dev packages installed. Then...
mkdir $HOME/tme
cd $HOME/tme
tar -zxvf your_download_dir/tme-0.8.tar.gz
cd tme-0.8
vi libtme/module.c (comment out line 93 "LTDL_SET_PRELOADED_SYMBOLS();",
it's no longer needed) and save.
./configure --prefix=$HOME/tme --disable-warnings 'LIBS=-lglib-2.0
-lgtk-x11-2.0 -lX11'
export LTDL_LIBRARY_PATH=$HOME/tme/lib (or "setenv LTDL_LIBRARY_PATH
$HOME/tme/lib" for csh/tcsh)
make
make install
If everything built and installed without errors, you'll have the install
tree in $HOME/tme. From here you can follow the various instructions on the
original site above for installing NetBSD, etc.
If you ran into any errors either building, installing, or running, just
drop me a note, I'd be happy to help!
P.S.: I've attached some photos of it booting up!
P.P.S: You'll notice it seg fault when you exit tmesh. The original does
this too. The author even comments about how there's no "quit" command.
Regards,
Mark
