This looks very cool. I wonder when the first web server running this
stack will come online. I also notice the presence of an IRC client. Has
anyone tried to chat from a PDP-11 yet?
You mean apart from mine, as Madame.Update.UU.SE is already serving
web-pages, and is running this software.
Yes, I use that IRC client myself every day.
(I'm also running this on a real 11/93 at home, by the way. Speed is
pretty ok.)

I'm happy to announce a new release of TCP/IP for RSX-11M-PLUS.
Since I'm broadening the scope of the announcement slightly, a more
complete list of features is included, and not just what changed
since last. For anyone who is currently running TCP/IP for RSX, I
strongly encourage you to update to this latest version. Several
improvements have gone in in the last couple of weeks. Most
important change is that there now is telnet support, both client
and server side.
The TCP/IP for RSX that I've written is sometimes referred to as
BQTCP/IP, just to make clear that it is a different product than
Process Software's TCPWARE, or JSA's TCP/IP.
BQTCP/IP is a rather feature rich TCP/IP implementation, which also
comes with libraries for various high level languages. The API is
not compatible, even at the source level, with Unix, but on the
other hand, if people write some code, they will see that it is a
very easy API to work with. The reasons for the incompatibilities
are several, including both resource concerns and differences
between how RSX works and Unix like operating systems.
BQTCP/IP has tried to comply with all relevant RFCs, but I'm sure
there are corners where it does not do things right. It also does
not demand much resources. It do require RSX-11M-PLUS with split I/D
space, and it has only been tested properly on RSX-11M-PLUS V4.6. It
should work on any version 4 release of RSX-11M-PLUS, but there
might be a couple of tweaks or fixes needed.
BQTCP/IP is distributed in binary form, so very little compilation
is required to get it up and running. However, pretty much all
utilities do come with sources. The actual TCP/IP stack sources are
not included. I do not have a good setup for distributing them in a
sane way, and it has had a low priority on my list of things to do.
But I do not mind distributing the sources as a general principle.
All that said, BQTCP/IP current supports the following protocols:
o Ethernet and loopback interfaces.
o ARP. BQTCP/IP can use Ethernet in co-existance with DECnet, or
standalone using the provided Unibus ethernet device driver.
o IP. The largest IP packets supported are approximately
8KB.
o ICMP.
o UDP. The largest UDP packets supported are approximately
8KB.
o TCP. The window is approximately 8KB in size, and TCP do
manage out of order packets in an efficient way.
BQTCP/IP supports the following applications:
o DHCP. DHCP can be used to configure interface addresses, network
masks, default gateways, DNS servers and NTP servers dynamically.
o NTP. NTP can be used to set the local time.
o TELNET. The TELNET server hooks in to the standard TT: terminal
driver, and the number of terminals to create is configurable.
The TELNET client can be used to connect to other systems.
o FTP. The FTP server can serve all kind of files to other RSX
systems, and can serve text and binary files to any system.
The FTP client can retrieve RSX format files from RSX servers,
and text, binary and block format files from any system.
o TFTP. The TFTP server and client can be used for simpler file
transfer operations.
o RWHOD. RWHOD is a program that reports current users and uptime
from RSX, for other systems to collect.
o IRC. IRC is a program to communicate with other users around
the world.
o IRCBOT. IRCBOT is a small example robot program connecting to IRC
and performing a service for IRC users.
o PCL. PCL is a protocol for printing, used by HP (and other) printers
over a network. The PCL implementation in BQTCP/IP appears as a
print symbiont, which you can create a printer queue for.
o WWW. WWW (or World Wide Web) is a service that can present hypertext
information to clients. The WWW server in BQTCP/IP also supports CGI,
which makes it possible to create dynamic content.
o DNS. BQTCP/IP have DNS implemented as an ACP, that anyone can query
to get translations between IP addresses and domain names. It also
supports different users using different name servers, or private
translations.
o SINK. A standard TCP service.
o ECHO. A standard TCP service.
o DAYTIME. A standard TCP service.
o QUOTD. A standard TCP service.
o IDENTD. A standard TCP service.
BQTCP/IP also have automatic IP spoof detection and prevention.
Additional tools are IFCONFIG, PING, TRACEROUTE, NETSTAT as well as
two new pages for RMD.
High level language libraries exists for BASIC+2, PDP-11 C and
FORTRAN-77.
I'm sure I have forgotten a thing or three, but that's a fairly
comprehensive list.
The documentation is a weak point, but there is hopefully enough
documentation to get people running, and I am happy to answer any
questions, or give support if needed. BQTCP/IP is already running on
the internet, and have been for a while. People who are curious to
check it out can ether look at http://madame.update.uu.se/, or
telnet to telnet://madame.update.uu.se <http://madame.update.uu.se>
and login as user GUEST with password GUEST, or use ftp against
ftp://madame.update.uu.se. Anonymous ftp account exist.
As usual, the distribution is available from:
ftp://madame.update.uu.se/bqtcp.dsk
ftp://madame.update.uu.se/bqtcp.tap
ftp://ftp.update.uu.se/pub/pdp11/rsx/tcpip/tcpip.dsk
The .tap file is an RSX virtual tape. It is only possible to
download and use if you are using FTP from anther RSX system and
fetch the file. The .dsk files are virtual RL02 images that are
useful both from within RSX as well as through emulators.
The documentation is also available through ftp on Madame, or also
at http://madame.update.uu.se/tcpipdoc
