DECnet Implementation and Productization of RSX-11M, 11S, 11D and IAS (was Re: Anonymous FAL (Tops-20))

by wilson＠dbit.com

From: John Forecast <john at forecast.name> [E11 on MIM] >Does the simulator actually simulate the caches or just the control registers >like SIMH? Just the control registers. I hate doing an emulation of a speed-up feature which actually slows it down (which is the case with the FASTBUS: emulation for dual PDP-11/45s but there was no way around that -- making the memory inherently mP-safe meant dinking with locks on every access, so it's *much* slower to touch it than non-"FAST" core). It might be interesting to do as a SET CPU option though, for testing how code would behave in nasty cases on a real 11/74. The fetch/decode/dispatch loop and the most common instructions are recompiled (from scripts) on every SET CPU command, so options like this can be added without penalty, as long as they're disabled by default. It'd be pretty painful though, since in this case *anything* that touches memory would have to be compiled at runtime, so it'd be a lot more code than it is now (less common instructions are static and check the SET CPU flags themselves on the fly rather than having their behavior hard-coded into the compiled code).

Anonymous FAL (Tops-20)

by tommytimesharing＠gmail.com

I have some software that I'd like to post, but don't recall how to configure FAL to allow for an anonymous connection; to download from a restricted directory. I know how to do it for the FTP server (seeing as I wrote it), but ... different code base. I can only vaguely remember what we did for CCnet at Columbia University in the 1980's, but I think it was kind of a hack.

Windows 10 DECnet?

My experience is that for connecting to a Tops-[12]0 system it works, even if the thing, as you say, sucks in several ways. Considering myself lucky then. --Johnny (the other one)

Windows 10 DECnet?

by tommytimesharing＠gmail.com

Does anybody know what the status of any types of drivers for DECnet or LAT on Windows 7 or above? I have the CD's from HP for Windows 2000, but I'll be darned if I can lay hands on them.? So I have a Windows 2000 laptop that has LAT on it and I can use that to run Kermit, which has been useful when I have really destroyed things. However, I just got a new Windows 10 machine and I'd like to put DECnet on it.? So is that bring your wallet?? Anybody know anything about PuTTY??? That would be straightforward to adapt to NRT and (maybe) LAT.? One assumes CTERM would be more effort. I have the latd package on one of my Linux hosts and that works great.? Right into the 20.? I have to scrounge up another Ethernet adapter before I reconfigure the whole thing for DECnet because of some connectivity issues.

Multinet 5.5 issues on VMS 7.3 (VAX) under SIMH

by Keith.Halewood＠pitbulluk.org

Hi, Is anybody running the NPTD functionality in Multinet 5.5 on VAX VMS 7.3 (under SIMH)? If so, how did you get it to work. I switched it on with a simple NTP.CONF and tried to query it. The logfile doesn't change much and I/O counts go up slowly. My attempts to query it usually result in a traceback. I'm a bit concerned by the lack of an NTPDATE command mentioned in the documentation, despite having done a full install. The timezone facility is a bit primitive too. I'm thinking of giving up with it. I have local TCP services on the machines hosting SIMH instances. One of them returns a local time string in VMS format, so I may make use of that in an RDATE-like fashion. Keith

DECnet broken with 4.4.0-151 kernel

by bob＠jfcl.com

Anybody else out there running DECnet on Linux? I recently upgraded from the 4.4.0-148 kernel to 4.4.0-151 and find that DECnet does not work with the latter. Connections always seem to hang at minimum, and frequently cause kernel panics. Has anybody found a fix for this, or is this the end of the road? BTW, 4.4.0-151 was released recently to fix the TCP SACK kernel panic problem. Bob

Processing time for Hobbyist Licenses

by mholmes10＠hotmail.com

Anyone familiar with the timeline for renewing Hobbyist licenses lately? I registered on the HPE site. In the past the turnaround was very quick, but it's been several days and nothing; so curious if this is the new timeline. thanks Mike

Announcing TCP/IP for RSX-11M-PLUS

by bqt＠softjar.se

Time for a new release announcement of TCP/IP for RSX-11M-PLUS. Highlights: This release have some rather significant work done on the mail system. There have also been some minor improvements on TCP, HTTPD, FTP and libraries. Detailed information on things that have been done since the last release: TCP: . Improved retransmission handling at Fin Wait 2. . Correct keepalive handling at Fin Wait 2. . Improved processing at socket close. TCP sockets should do keepalives, and not probes when in Fin Wait 2. Libraries: . Corrected program section attributes on some modules in BQTLIB, so that they work correctly also on overlaid programs. . Bugfix in BQTC library. Recent changes to quadtime to string conversion had introduced a potential buffer overflow error. FTPD: . Change FTPD read command processing to avoid a race condition. HTTPD: . Reworked logging routines to fix some performance issues. . Bugfix in IND forms library for CGI scripts. MAILD: . Changed mailbox format for better performance. . Changed location for mail spool file. . Added checking for /NOBRO for new mail announcements. . Increased stack size since the task sometimes ran out of stack. . Reduced static data memory use. . Changed overlay scheme to make more memory available. . Added various error checks in the code. . Changed usage so all queue operations requires a user with privileges. . Added label handling for mails. . Added copying of sent mails to self. . Improved error mail generation in MAILD. . Added mail size information to mails. . Added conversion tool for old mailboxes. *** Important notice about MAILD *** The changes to MAILD are not seamless. When installing the new version, the mailbox update program should be run, in order to upgrade all user mailboxes to the new mailbox format. The task for this is MBXUPD.TSK. There are no issues with running this task several times. A mailbox that has already been updates will not be modified anymore by the update task. The location of the mail queue file have moved. After installation, you could just move the mail queue file over to the new place, or else re-initialize the mail system. The mail queue file name is MAILQUEUE.DAT, and it was previously located at MAIL$:, but it should be moved to LB:[1,7] instead. Once the mailboxes have been updated, and the mail queue file have been moved/recreated, the mail system have been updated, and you are ready to use the new mail system. *** Important notice about MAILD *** 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. While there are no really critical issues that have been solved, I still recommend people to update, since this new version do contain improvements that are beneficial and as far as I know there are no issues or problems updating to this newest version.
