Time for a new release announcement of TCP/IP for RSX-11M-PLUS.
This release contains a lot of fixes and improvements in many areas.
There are a couple of very serious bugs in TCP that is fixed in this
release which is why I really encourage people to upgrade. (They do not
happen often, but if they happen, they have a high chance of crashing
the system.)
Highlights:
- Stability and reliability improvements in TCP.
- Improved DHCP
- Improved TELNETD
- Improved FTP(D)
- Improved HTTPD
- Improved MAIL(D)
- Improved Multinet
Detailed information on things that have been done since the last release:
Installation process:
- The IPGEN script now optionally cleans up the disk after installation.
TCP:
- Bugfix in TCP slow start window computation in combination with TCP
RTT calculation. If the RTT was above mininum, the slow start window
never grew.
- Changed TCP Fin-Wait-2 state to not reset timer if unexpected packets
are received.
- Stop slow timer at TCP close, so that it can be re-primed with an
appropriate timeout.
- Added proper handling of SYN packets at the closing stages of a
socket. They should always cause RST packets.
- Improved handling of the slow timer at the closing stages of sockets.
Sending packets at those stages should not stop the timer.
- Add handling of two TCP SYN packets comes in from same address/port to
same address/port but with different sequence numbers. Second req. will
be reset immediately.
- Improve handling of failed daemon activations from TCP.
- Bugfix. If several creates were done for the same TCP connection, the
stack got corrupted.
- Bugfix in IO.CON. It could create a new connection for an already
existing one.
- Bugfix. If a read from TCP give error result, we should not unblock
user ASTs.
- Corrected AST block setup in TCP.
- Add PU.NBL option for non-blocking writes to TCP.
- Bugfix in TCP. IO.SXS, IO.SRS and IO.SSS was not working.
IFCONFIG:
- Disallow changing interface parameters on a running interface.
DHCP:
- Corrected bug in DHCP, where lease time was computed as a signed number.
TELNETD:
- Improve TELNETD connection tracking and disconnection handling.
- Bugfix in TELNETD. If socket create failed, TELNETD could go catatonic.
- Improved telnetd accept handling.
FTP(D):
- Bugfix for FTP, which caused RSX and block mode transfers to sometimes
fail.
- Improved RSX mode FTP transfer mode under some circumstances.
- Enable ftp to put block files.
HTTP:
- Bugfix in HTTPD. WWW.B2S failed to include BQTLIB.B2S, and therefore
missed function prototypes causing function to be called the wrong way
in the main function.
- Improve error handling for HTTPD when running CGI scripts.
- Improved handling of CGI interface in WWW.
MAILD:
- Improved mail headers for MAIL11 received mails.
- Improve MAILD handling of text/plan with format=flow
- Add user-agent header to composed mails.
- Add MIME headers to mail sent over smtp.
- Improved logging in MAILD.
- Added handling of mail address loops in MAILD.
- Added mail forwarding for MAILD.
- Improved error handling in MAILD mail delivery.
- Improve MAILD client RMS handling.
- Bugfix in MAILD. For MAIL11, VMS systems can send empty lines that
MAILD interpreted as end of mail. Fixed now.
- Fix mail processing. SMTP did not reject invalid local addresses. SMTP
now rejects destinations on other hosts, as we do not allow relaying.
- Corrected mail printouts which skipped empty lines.
- Added FILE command to mail client.
Multinet:
- Improve Multinet handling of failing lines.
RMD:
- Added more information on the RMD network page.
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
The firewall for Mim have now been removed, so no need for the alternate
ports, but Mim is still listening to the alternate ports as well.
ftp: 10021
telnet: 10023
As a final word about this release. As always things progress with time,
but I think it's safe to say by now that BQTCP is now a very stable
TCP/IP with almost all features one can expect. There might always be
some more work on the lower level protocols, but at this point, expect
that most work and updates will be more and more on various daemons and
clients.
If there is anything in particular anyone is looking for, let me know.

Johnny,
Thanks again for another great release for TCP/IP for RSX-11M+. I?ve been checking and
updating my RSX systems with the incremental
releases which I have batch files to FTP down the new tape. Reboot without TCP/IP, BRU the
new files off the tape, run the IPGEN and start up the updated TCP/IP. It all takes about
10 minutes on the 11/83s.
One minor documentation request I have is the HOST2I & IP2HOS routines in the
README.DOC for the example file [IPF77]TEST2.FTN I?m
Trying to extend that example to print on port 9100 of a HP laser with more control than
the PCL batch printer with its odd use of forms to send escape sequences. While playing
with the examples and TC port in general I ran across the port 17 cookie generator. Since
I have a cookie
program running it worked perfectly and I found that PIP works well to fetch virtual
cookies:
PIP TI:=TC:?192.168.0.31?;17
or
PIP TI:=TC:?Frodo?;17
It also took addresses that the DNS server translated (not just the LB:[1,2]HOSTS.TXT
ones), so it was interesting to see that MIM has some cookies I?ve not heard of before,
particularly Murphy?s Laws on ?Love?. He had some great laboratory observations, but his
observations on interpersonal relationships really struck my funny bone.
Again, thanks for all the hard work. We do appreciate it!
Best Regards,
Mark Matlock

Nice to hear. Personally, when I update some system other than my
development ones, I download the tape file, run BRU to pull out the
files, run IPGEN for update, and then reboot. Timewise I expect it is
similar.

HOST2I & IP2HOS routines in the README.DOC for the example file [IPF77]TEST2.FTN I?m

The documentation is definitely a work in progress with lots of things
lacking. What specifically do you need? I'll write whatever up as soon
as I get a request for it. :-)
As for using forms, it is pretty much in the same way as DEC used it for
the LN03 printer, from where I got the inspiration. I think it is a
pretty nice way of printing in different formats.
PRINT /FO:0=filename to get portrait A4, and PRINT /FO:1=filename to get
landscape A4, for example. Both on the same printer.
But my PCL code is really unfinished. I should implement printing
through file numbers, which is required for some situations, and I
should get some nice banner page implemented. Also, the actual format of
the page have not been fully tested. I read up some on PCL when I was
doing the code, but I got distracted by other things, which left this in
the unfinished state it is in.
Also, the current spooler code will not allow a printing job to be
aborted, since it does not read out the next message from the queue
manager until the current job is finished.
So many things to do... There just isn't enough hours in a day. :-)
While playing with the examples and TC port in general
I ran across the port 17 cookie generator. Since I have a cookie

That is nice, isn't it? :-)
And of course it will use whatever methods you have defined. Not sure
how aware you are that the logical name RESOLV$ORDER is the thing that
controls this, and in addition to the system logical, you can have your
own as well, which changes how it works for just you. And you can have
your own HOSTS file, and you can define hosts through logical names
(also user local ones), and you can also use a different DNS server, if
you want to. All controlled by the logical names.
And of course it also works when used as foreign file names. It would be
horrible otherwise. :-)
Again, thanks for all the hard work. We do
appreciate it!
Always happy to get feedback, and to hear of others experiences.
Johnny
