Hi
Got OS X Lion running inside a VirtualBox - obviously the first thing I want to do is to see if it can talk DECnet. The forums mention a ?Pathworks for Macintosh? product. Does anyone know where to get a copy of it?
Thanks

Hi there, everybody! I'm a vintage computer collector in southern California, USA, and I'm interested in joining HECnet. I thought I'd introduce myself and then ask some questions on the mailing list before I ask to join the network.
One of my favorite computers in my collection is a VAX-11/730 system with an R80, RL02, TU81 and DECwriter III. It has an ethernet card, and it came with OpenVMS 7.3 on the R80 and VMS 5.3 on an RL02 pack. I don't seem to have a single good TU58 tape, even after repairing the capstan rollers in the drives, but I can boot up the computer via tu58em. I've shared the boot-optimized console tape image I put together, as well as an image I created of the CRDPACK RL02 pack that came with the system:
https://github.com/NF6X/VAX-11-730-Console-v57
It's been a couple years since I fired up that system, but I recently had another burst of interest and began setting up some VAX emulations in simh. I have a simulated VAX-11/785 running in simh on a BeagleBone Green (a little embedded computer board, similar to the Raspberry Pi). I plan to leave it running as a full-time VMS presence at home, so it can be up on HECnet all the time. It would be a natural host for any bridging or routing I need to do, and I plan to use it as my main bridge between my modern computers and anything I have speaking DECnet. I have TCP/IP set up on it so I can FTP files on and off of it from my modern systems. The 11/730 won't be powered up very often, and probably mostly during winter!
I have plans to restore a heap of parts that I have into a working PDP-11/44 eventually, and I suppose it should be able to run RSX-11 and also visit HECnet?
I expect that I'll probably get more DECnet-capable hardware in the future. I'd like to get a PDP-11/73 someday, and I'm curious about those little QBUS MicroVAXen. Maybe I should add a VAXstation to the mix, too?
So now it's time for me to figure out how to join HECnet. I gather that my best options would be to either use the bridge program, or to set up my VAX-11/785 emulation to bridge things somehow.
If I use the bridge program running on a Linux box, can I configure it to only bridge traffic to/from the rest of HECnet? I don't want the traffic between my local DECnet nodes to leave the house. If the bridge program forwards all DECnet packets that it sees, then maybe I should learn how to set up my emulated VAX-11/785 as a router instead?
And now for the really tough question: Once I add my systems to HECnet, what can I *do*? I'd like to join HECnet just because it's there, but it would be swell if there's more fun stuff to do.

Hey folks. I'm trying to get "Swedish" Pascal v6.3 running under
RSX-11M-Plus v4.6, and have hit a problem. The created PAS.TSK crashes
on invocation, and I suspect it may be due to a patch that gets applied
to a library during the build process. This appears in PAS.BLD:
;
; The above GBLPAT statement patches a branch instruction
; into the system overlay autoload routine AUTO.
; The last few releases of most operating systems have had
; different versions of AUTO. The proper GBLPAT statement
; to use above depends on which AUTO routine you have on
; your system. You can identify which one you have by
; examining the object module ident of module AUTO in
; the system object library, SYSLIB. Use a command such as
; "LBR LB:[1,1]SYSLIB/FU" to do this. The GBLPAT statements
; to use with each AUTO routine are:
;
; AUTO ident GBLPAT statement
; ============ ==================
; ??early?? GBLPAT=ROOT:$AUTO+34:437
; 08 GBLPAT=ROOT:$AUTO+34:435
; 09.08 GBLPAT=ROOT:$AUTO+36:441
; 10.02 GBLPAT=ROOT:$AUTO+36:431
;
The ident of AUTO in my system is 10.05, making that patch potentially
land at the wrong address. However, that's just my suspicion. Has
anyone gotten Swedish Pascal v6.3 running under RSX-11M-Plus v4.6?

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 is one very serious bug in TCP that is fixed in this release which
is why I really encourage people to upgrade.
Highlights:
- Stability and reliability improvements in TCP.
- Improved SPOOF detection.
- Improved stability.
Detailed information on things that have been done since the last release:
Installation process:
- The IPGEN script now more smoothly handles updates to an existing
installation.
Ethernet driver:
- Improved driver reset handling.
- Implemented MTU backoff in ethernet driver, to handle unpatched DEC
XU: driver.
TCP:
- At socket close time, if there were pending packets to process still
in the socket, the system pool could become corrupted, causing a crash
at some random later time.
- Add more spoof processing for suspicious connections.
FTPD:
- Improved error handling for not logged in clients.
HTTP:
- Implemented spoof processing for connections which looks suspicious.
MAILD:
- Implemented spoof processing for connections which looks suspicious.
Mail client:
- Added basic hooks for extending mail to deal with several folders
(still not complete).
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.

Before I go looking on Ebay, I thought I'd ask here first.
My Alphaserver 800 5/500 wasn't responding when I came back from a business trip.
And when I rebooted it, I heard the 1-2-4 beep codes and no screen.
Found out it means "Backup cache error. Replace the CPU daughter board"
And I found out in the manual that "The system can be operated with the B-cache disabled until a replacement CPU daughter board is available." After re-seating the CPU board and the memory it still got the error beeps and changed the J1 jumper and it booted up fine.
Does anyone know the impact of running with the B-cache disabled?
The text in the system manual said the jumper setting "Allows the system to run despite bad B-cache until a replacement CPU board is available." How long can the system be run in this mode?
just curious so I know how much time I have to watch for a reasonable price 5/500 CPU module to show up on ebay (since there aren't many VAX/Alpha geeks in DC on craigslist).
Thanks in advance
Mike
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. I
really encourage people to upgrade, as some of these changes can have a
noticeable impact on stability.
Highlights:
- Distribution now includes the PDP-11 C and BASIC+2 resident libraries,
so that various tools and utilities that are built against them can
be installed even if the full language is not installed on a system.
- Improved stability.
Detailed information on things that have been done since the last release:
Ethernet driver:
- The ethernet driver could under some overload situations become deaf,
and not receive any more packets.
TCP:
- TCP FIN handling. Under some circumstances, TCP could get into a state
where both sides would be sending FIN packets, and not acknowledging the
other sides FIN.
- TCP sequence handling. Under some circumstances, TCP packets with bad
sequence numbers could be accepted as valid packets.
- IO.KIL function for normal TCP ports removed. It turned out that it
was very undesirable to process IO.KIL for connected sockets. (A
separate function with the same effect does exist.)
- Added counted for rejected TCP SYN packets.
- Improved task activation code for TCP daemons.
HTTP:
- Improved logging.
MAILD:
- Improved new mail notification handling.
- Correct handling of EHLO/HELO for SMTP.
- Implemented proper MAIL11 protocol, version 3.
- Rewritten address rewrite logic to better process both SMTP and MAIL11
addresses.
MAIL:
- Simple mail client now exist.
Libraries:
- Unified user lookup functions. User lookups now happen both on
lastname, UIC, SID and login directory. This is used both by MAIL, FTP
and HTTP.
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.

Hi,
Just letting those people who use the Cisco GRE tunnels that my static
IP has changed (moved networks). It is no longer 120.146.225.243. It
is now 110.141.227.104.
Regards, Tim.
Tony,
Flakiness seems to have gone down a wee bit once I replaced
/usr/sbin/dnetnml with a binary built from dnet-progs source. It is
staying up and responding to SHOW EXEC CHAR requests for almost a full
day now.
So far I have replaced two binaries in /usr/sbin with built-from-src -
dnetnml and ctermd.
BTW I tried to reach MASTER but it was down. My two nodes are at 1.553
and 1.554. Would you like an account? And could I have an account on MASTER?
Thanks
Supratim
