Right now we've got 46 areas in use, out of ?63 possible areas. Each area can have 1023 nodes and few areas will have as many right now.
I use area 44 and own probably the most systems but even then I only really need 70 addresses.
Which means that even then we could at least accommodate 63*15=945 "sites"

About three months since I last announced anything. There have been
various development since, and I figured I should encourage people who
are using BQTCP/IP for RSX to upgrade to the latest release.
A short list of changes:
ICMP:
. ICMP packets accidentally lost the source IP address informaton when
returning information to a program. - Fixed.
TCP:
. User timers on TCP sockets could erroneously stop. - Fixed.
. User timers now reset on completed reads, so that you do
not get a timeout if you are constantly completing reads.
. Sockets in Fin-Wait-2 could sometimes get stuck in that state.
- Fixed.
. If a TCP session got an RST, it could get into a bad state. - Fixed.
. Added the ability to send URGENT data in TCP. (Receive ignores any
URGENT flags.)
. Added a special I/O function to read from TCP without formatting.
DNS:
. Improved stability of DNS client daemon code.
FTP:
. FTP client and server performance improved.
. FTP server logging added.
. Improvements in FTP server and client for handling files with implicit
CFLF.
. Implemented primitive handling of Unix file paths implemented in FTP
server. This allows most web browsers to access FTP repositories
under RSX.
I also did some performance testing using FTP.
FTP from a modern Unix system of BQTCP.DSK in binary mode to both RSX
and 2.11BSD, running under simh on the same physical machine:
2.11BSD: 210s
RSX: 141s
From RSX (E11) to the same machines:
2.11BSD: 240s
RSX: 137s
I honestly do not know why transfer from RSX to 2.11BSD took longer than
from Unix, but transfer from RSX to RSX was faster compared to Unix to
RSX. I would have expected both to be slower or faster. But the numbers
are interesting, and show that the RSX TCP implementation is doing
fairly well, even through it goes through the DECnet ethernet driver, as
compared to 2.11BSD which runs TCP/IP more "native".
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 documentation is also available through ftp on Madame, or also at
http://madame.update.uu.se/tcpipdoc
I hope people will find this latest release useful, and my next project
right now is telnet.

Thanks. I've just addressed this. I don't know how this slipped but it's
now been renewed.

I speak to machines with the voice of humanity.
I've just uploaded all I have here:
http://www.wickensonline.co.uk/static/files/Ultrix/
I can't guarantee all the images work, but the images in the v4.4
directory were ripped from original CDROMs by me - so if there is an
issue with these they can probably be corrected.

Is there a quick way in PDP-10 DDT, FILDDT most likely, to dump a list of every symbol?
I need to find where the IP address in this monitor for which I have no documentation is stored. It seems it isn't stored as an ASCII string ;)
Interestingly, the string that tells me the IP address doesn't show up in `strings` although it could very well be SIXBIT.

Hey,
I can't remember the limitations between a Phase IV and a Phase III node
interacting...aside from the limited area and node numbers.
Can Phase IV be used as a bridge to access Phase III nodes?

It just came to my attention that a pair of RP07 drives in the north of
Sweden needs a new home. One functional, the other in unknown state.
If anyone is near (unlikely) or interested in a long drive (very long),
let me know.
Messages have been passed to several parties, so if several are
interested, we'll sort things out at that point.
Johnny
Yes, if it is not needed to be picked up right away.

I'm just about to hit the sack. I'll send a mail to you, Ragge
