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,
Thanks for the new release of TCP/IP for RSX11M+! (And Happy New Year!)

I’ve installed it on a couple systems so far, one a real PDP-11/93 and a PiDP-11/70. Following your instructions everything went smooth.
The only thing I ran into was that my [1,2]STARTUP.CMD calls another INSPROG.CMD from which IPINS.CMD and IPAPPL.CMD get called
and at some point Indirect nested too far. Using .CHAIN instead of @ from the STARTUP.CMD fixed that. Other than setting the SYS$UTC_OFFSET
for my timezone those were the only issues I had to change.

The new IPCONFIG approach would make setting up a new system very easy!

Thanks again for all the great work!

Hello! Is there a useful guide or manual somewhere for using TCP/IP FTP under RSX11M+? I would like to exchange data or files between RS11M+ and Windows 10 with WinSCP!

Stephan,
     Take a look at chapters 6 & 7 of LB:[IP]README.DOC on Johnny’s TCP/IP for RSX11M+. The best way to view this file is to use MOR from Johnny’s RPM software distribution system. If you have a terminal emulator that supports >24 lines MOR will display that many lines of the document. It does require that you set the value of lines n your terminal.

>SET /LINES=TI:60.

Best,
Mark

Yes, there is.
http://mim.stupi.net/manuals/NETWORK/readme.doc

And no, you cannot use SCP, since there is no ssh for RSX. Use FTP instead.

That file is also available over HTTP as
http://mim.stupi.net/manuals/NETWORK/readme.doc.
But yes, chapters 6 and 7 are the most relevant to the question.

Hello RSX11M+ friends!
Thanks for your assistance. I found the document bqtcp.txt and read it through.
Unfortunately, the content is more for an IT freak who wants to get a deep insight into TCP/IP.
My RSX11M+ knowledge dates back 50 years and there was no communication network.
What I need is just a short description of how to transfer a file from RSX11M+ to
Windows 10 or vice versa via FTP!
My naive idea of using FTP is this:
1.Starting FTP on RSX11M+ and Windows 10.
2.Establishing a TCP/IP connection between the systems (which IP address, user ID or password? ).
3.Move file between systems.
4.End the connection between the systems.
For this process I need a simple working example.
Stephan

Hi.

I'm sorry. I thought you knew how to use ftp.

Basically, you can either use it from the command line. Using a Mac it
looks like this (it would look the same with Linux/Unix or Windows as well):

There are also screen based ftp applications. But in general, it works
the same way. You connect to the host, login with username and password,
then you can list files, get and put files, change directory if needed,
and so on.

Unfortunately for us vintage enthusiasts, Microsoft and others have been removing legacy protocols that are not secure, such as FTP and Telnet. It is no longer possible to use them from the Windows command prompt; unless you install 3rd party tools.

You can still use FTP from Windows File Explorer
Open it, and enter the FTP location in the location box.
Something like: "FTP://us...@192.168.0.101"
It will open a dialog asking for the password, then provide you with a view of the FTP server's content.
You can then drag-drop files to and from Windows and the FTP server.

Both command-line ftp and telnet are available but you need to enable them via "windows features".  It takes less than a minute.
