Hi all
I've moved my SIMH VAXen to a new host with a new version of SIMH (the
current 3.11 that I found - is there a newer version?)
Main host runs Devuan Linux (yes, I'm a systemd hater). VirtualBox VM
hosts the SIMH instance, also running Devuan Linux.
My area router, FRUGAL, boots fine and gets adjacency with my
Multinet-over-IP connections, that is, LEGATO, MIM, and 31.3:: as well as
other DECNet hosts (MISER, CHEAP)
However, the connection from FRUGAL "flaps" (going up and down) quite a
bit with local DECNet hosts as well as the ip-connection to 31.3::
I've tried eliminating the connection to 31.3:: as the culprit by turning
off the circuit, and the connection between FRUGAL:: and MISER:: (both
local nodes) continues to go up and down every few minutes.
I'd welcome some pointers, things to check, etc. Is there such a thing as
an adjacency timer perhaps I could crank up a bit?
Thanks
Fred
I just updated the current nodenames on a CISCO router after quite a
while using this. Posting this here in case this is useful for others
with CISCOs, possibly saving some awking and sedding.
This includes today's addition of A2RTR.
Best,
Supratim

I have switched from using LEGATO as the area 2 router to using Paul's
pyDECnet router instead. I'm very impressed - it doesn't run under VMS, but
other than that pyDECnet does pretty much everything you could want to do
with DECnet or HECnet all in a single package. It only took me a couple of
hours to get it all set up, and it can manage all the Multinet links and the
one "Bilquist Bridge" link that were formerly attached to LEGATO.
The new router for area 2 is (what else?) A2RTR, 2.1023. Johnny, please
add this node name to your database.
LEGATO is still there, but it's been demoted to an L1 router and it
doesn't do anything now except route between HECnet and the real, physical,
machines in my house.
For the people who were/are connected to LEGATO there should be no real
difference except that you'll now see A2RTR on the other end of the link
instead. Everything else should work as before. Let me know if you find
some problem.
And a special thanks to Paul and Supratim for answering my silly questions
and helping me set it up.

I would not recomend DDCMP over TCP, as you have no idea what the
TCP implementaion does for timers etc and TCP is streams, you need
to identify the packet boundaries.
DDCMP over UDP gives DDCMP full control over retransmit timers etc
for making the connection reliable and what the actual netwrk is doing
is visible to the DDCMP layer.

For what it's worth, Ersatz-11 (my PDP-11 emulator) also supports DDCMP
over UDP, and I don't consider it ugly at all -- it's a very neat fit.
(E11 can also use TCP, or actual real async DDCMP over serial lines, and
there are the beginnings of support for DDCMP on sync lines too but
usable hardware for that is rare.)

I am happily running an instance of pydecnet (1.0-486) to connect my
simh VAX cluster and various other stuff to HECnet (ONAPI4 29.206)
For management purposes, I'd like to periodically zero the
line/circuit/node counters on ONAPI4, but the node does not respond to
the "NCP tell ONAPI4 zero <xxx> counters" commands.
Looking at the python code, I saw some hints bit I can't get my head
around how to do this, either using the pydecnet api or remote NCP
Any help here?

I just wanted to alert people that I rewrote parts of the bridge code
recently.
The code was very old, and it started to have problems on some platforms
because of the very ancient way it made use of the pcap library. So I
finally bit the bullet and rewrote it to make use of the pcap library it
is supposed to be used these days. This not only removed some
bugs/issues, but it also allowed me to remove some conditional code for
different OSes.
In addition I also introduced some other changes that others have
contributed, making it hopefully a little nicer to use.
The bridge tarball can be found on:

Hi all,
Does anyone happen to have a digitized copy of "Jnet NJE Manager's
Guide" from Wingra Technologies? This applies to Wingra's JNET for VMS
product, version 3.6 (or 3.5 or 3.7) which connects VAX/VMS systems to
IBM Mainframe networks using NJE over DECnet or TCPIP.
Thanks,
Supratim

Time for a new release announcement of TCP/IP for RSX-11M-PLUS.
Highlights:
. The installation and configuration tools have been totally rewritten
to make it easier to use for novice people, while at the same time
making updating and customization easier to to do.
(*** IMPORTANT, READ NOTE AT BOTTOM OF MAIL ***)
. MAIL now have an API for access from programs both to read and send
mail, and also hooks to have a program run when new mail is received.
Detailed information on things that have been done since the last release:
Installation and configuration:
. Totally rewritten scripts to configure and install BQTCP.
(*** IMPORTANT, READ NOTE AT BOTTOM OF MAIL ***)
TCP:
. Improved TCP ACK handling. Fast to slow machine caused excessive ACK
packets to be generated.
. Correct TCP daemon accept so that two different requests with the same
source and destination, but different sequence numbers don't end up
creating two sockets.
. Correct ACK # if doing an RST to a SYN, which could be wrong.
. Improve handling of duplicate Syn in Syn Recv state.
. Improved TCP receive window update strategy.
. Bugfix in TCP ICMP error handling reception. Improved handling of
problems during TCP Syn Sent state.
. Rewritten TCP retransmit and congestion avoidance logic to better
match RFC 5681.
. Improved TCP retransmit and FIN logic.
. Improve TCP Nagle. Under some circumstances, it failed to perform.
SPOOF:
. Added address exception handling for spoof.
MAILD:
. Improved MAILD local list handling and SMTP DNS lookup error handling
. Correct MAIL address rewriting rules when transitioning between protocols.
. Added in MAIL that just a number as command means read that mail.
. Improved MAILD address rewrite logic, and smtp sending to better
handle various error situations.
. Bugfix in MAILD. CC could accidentally be set for mails under some
circumstances.
. Added handling of in-reply-to and references in MAIL.
. MAIL have been split into a mail queue manager (MQM) and a mail reader
(MAI).
. Bugfix in MAILD. Unprivileged users did not work right.
. Bugfix. MAILD didn't enable privs before trying to send notifications,
causing them to sometimes fail.
. MAILD didn't turn on privs before entering mails in the mail queue,
causing this to sometimes fail.
. Added API for user programs to easily access mail box.
. Added API for programs to be run when mail is received.
. Added API for programs to send mails.
LPT:
. Bugfix in LPT. Symbiont did not respond to start and stop messages
from queue manager.
C library:
. Bugfix in BQTC. RCVDW function was not working right.
HTTPD:
. Correct URL matching in HTTPD to not overly match wildcards.
*** IMPORTANT - NEW INSTALLATION AND CONFIGURATION ***
The installation and configuration scripts have been totally rewritten
for this release.
The main reasons are to simplify configuration for novice users, to
simplify future updates, to simplify customization, and to also make it
easier for expert users to change things as needed.
IPINS.CMD and IPAPPL.CMD have been rewritten, and are now installed
and used from the distribution. If any local customization have been
done on these file in the past, they will not be applied any more.
The old version of these files are kept, so you can go back and look
at them and see what customization you had done. But going forward,
no editing should be done to these two files. Instead there are hooks
for customization available from these scripts, which should be used
for any special configuration on a host. However, most normal
configuration should happen through the IPCONFIG mechanism instead.
Any current installation should do an update as usual by fetching and
installing the new version, after which IPGEN should be run.
IPGEN now will only ask a few questions, even if doing a "full"
installation.
At the end of IPGEN, a check is made if a configuration exists, and if
not, IPCONFIG is also run.
At the first update, this will be the case, so expect to have to
redefine your system's TCP/IP configuration again.
Any subsequent update should not require any further configuration work
to be done. However, if any new configuration values are introduced,
this will also be indicated at this point, and optionally, IPCONFIG will
be run to correct the assumed defaults for these new values.
If IPCONFIG have not been run before trying to bring the TCP/IP services
up, IPCONFIG will be automatically invoked at this point as well, and if
configuration is not done then, TCP/IP will not start.
This also means that a system for distributing to others can be done
while leaving the TCP/IP configuration undone, and it will be done at
startup.
As before, there is two scripts that should be invoked at system
startup. IPINS, which should be invoked early in startup, but after
DECnet, if DECnet is also installed, and IPAPPL, which should be invoked
close to the end of the startup process.
If required, configuration of TCP/IP can be redone at any time by just
running LB:[IP]IPCONFIG.CMD. The current configuration will be provided
as the default answers to all questions.
If required, an existing config can be removed by just renaming or
deleting LB:[1,2]IPPARAM.CMD.
More details, as well as information about customization, can be found
in the manual.
*** IMPORTANT - NEW INSTALLATION AND CONFIGURATION ***
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
I hope people find this update useful.
Johnny
