Apologies to those downstream of me on area 29

by Keith.Halewood＠pitbulluk.org

Hi, Apologies for my HECnet connections being up and down over the past day or two. I finally decided to 'upgrade' to a Draytek Vigor 2865ac router from the older 2862ac and/or the home grown linux/pf-sense I have been experimenting with on and off. Anyway, the documentation stated that I could dump the config of the old vigor and install it into the new one. It looked ok but quite frankly wasn't. Half the WAN side of things wouldn't come up and kept crashing the entire unit. So I configured it from scratch... and cleared out a load of old stuff as a result. Routing policy doesn't work properly and gets misconfigured when you're not using the default 'address of router' for NAT-based operations - support request logged. IPv6... yes I know you don't want to know or care... nevertheless... There's some (state sponsored?) port scanning on random IPv6 host addresses with my prefix. The router is naturally blocking them but the damned IPv6 neighbour table is filling up with them! They don't go anywhere, but over the last few hours, the table now has about 900 entries - another support request logged... and the bloody router hasn't been out of its box for more than a day!

Is MIM running?

. I can't seem to reach it. It's not a big problem, but I wondered if it was my issue or somebody else's. Bob

A2RTR downtime

by bob＠jfcl.com

A2RTR will be down tomorrow (Monday) for a couple of hours sometime between 9AM PDT and 3PM. It's not my doing - PG&E is replacing a transformer and the power will be off. I have battery backup for some of my equipment, but not A2RTR. Sorry. It's also going to have to go down sometime again, maybe next weekend, so I can replace a disk drive that's failing. I bought two identical drives and plan to set up a RAID 1 array this time. If anybody has set up a software RAID on Ubuntu, using the md driver and mdadm, for the system drive and you have advice, let me know. Espcially if you managed to make both of the drives bootable.

Some scanned documents for DEC

Just reviewing a retrochallenge entry when I came across some scanned DEC documents that may not be available anywhere else: https://jbretro.wordpress.com/the-latest-google-drive-link/ Regards, Mark. -- https://www.qrz.com/db/M0NOM/P

PDP-11 Unix V7M-11 V1.0 under SIMH

by tony.nicholson＠computer.org

Recently Al Kossow made available a zip file containing a Micro/PDP-11 installation kit for Unix V7M-11 V1.0 on bitsavers as RX50 disk images. Tinkering away here in Covid lockdown, I've managed to get this running under SIMH pdp11 emulating an almost historically accurate PDP-11/23 plus. I've placed the SIMH initialisation file, a couple of RD51 disk images and an "installation recipe" for making these disks on GitHub at - https://github.com/agn453/V7M-11 While I mainly had exposure to later versions of Unix and Ultrix-11 on a PDP-11/70 as an undergraduate - this one surely brings back memories!

Back on HECNET!

by mark＠wickensonline.co.uk

After a prolonged outage Area 4 is now back on hecnet via a new Raspberry Pi, so the archive on SLAVE:: is now available again (all the time the windows vm that it is being emulated on is up) as well as a debian VM hosted SIMH ORAC recreation. I'm planning on using a (real) VAXstation during this years October Retrochallenge (it starts tomorrow): https://www.retrochallenge.org/ Twitter: @retrochallenge After a shaky couple of retrochallenge I've decided to step in and help out with this one, but will also be hopefully using it as an excuse to spend a bit of time on DEC equipment. Also please note that it is DEC Legacy in Windermere, UK in two weekends: 9th/10th October. http://wickensonline.co.uk/declegacy/ Regards, Mark. -- https://www.qrz.com/db/M0NOM/P

Announcing TCP/IP V2.7 for RSX-11M-PLUS

by bqt＠softjar.se

This is a re-release announcement of TCP/IP for RSX-11M-PLUS. This is version 2.7 of BQTCP/IP. The reason for the re-release is that the patches mentioned for TTDRV were incomplete, and lacking instructions about them. This has been fixed now. It's been five months since the last official update, and there been various smaller improvements. Highlights: . Many daemons now run under NETUIC, if defined. Which means logical names that are mainly used for configuration of these daemons now can be in that group logical name table instead, which removes a bunch of logicals from the global table. . Improvements have been done to TCP to be able to have larger buffers, if desired. . Patch files for the TT: driver have been included, which if used, can be combined with a new task to get logical names defined at login time, which tells from where a user connected using telnet. See [TELNETD]README.TXT for instructions on how to install the patches for the TT: driver. Detailed information on things that have been done since the last release: TCP: . Removed immediate ACK for TCP packets with PSH set. . Added settable TCP syn queue maximum size . Bugfix. TCP retransmissions failed if window size was 0. . Reworked TCP FIN logic and buffer management. TCP can now deal with up to 64K buffer size. . Added IO.IFL function to TC: . Added _iflush() to IPC library. TELNET: . Added TNC2 task to define logicals at telnet terminals at login. . Added files needed to update terminal driver with additional functionality. See README.DOC on TNC2 for details. . Changed TELNET to run under netuic. FTP/FTPD: . Added the ability to set a session timeout for FTPD. . Changed FTPD to run under NETUIC. . Added handling of TI: in FTP GET/PUT commands. . Added handling of TI: in FTPD STOR/RETR commands. . Added handling of file attribute errors in FTP/FTPD. . Improved ETA computation in FTP, when data rate is low. MAILD: . Improved MAILD to not use a separate MAILDN task for new mail. Local mails are now delivered by MAI..., which also is responsible for the local mail API. . Rewritten maild automatic forwarding handling. . Improved MAILD error mail generation. Multinet: . Improved active tcp multinet connection handling. LPT: . Fixed LPR mode of LPT spooler. . Changed LPT to run under netuic. HTTPD: . Improved httpd error logging. . Added more logging information in HTTPD. NTP: . Changed NTP to run under netuic. DHCP: . Changed DHCP to define NTP logical name in group table. IPINS: . Changed IPINS to define logicals for DHCP, FTPD and TELNET under the network uic group instead of global. Some additional notes: As usual, I would recommend people to update as soon as possible. The changes are not critical, but will lead to a much better experience. The patches to the TT: driver cannot be applied automatically, but requires users to apply the patches themselves, and then run SYSGEN to generate a new system. Once added, the TNC2 task can be run at login, and will define logical names for the user telling where he is connected from, if using telnet. The TT: driver patches also allows the updated MCR to give more information with the DEV command (SHOW TERMINAL in DCL). 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 !!! BQTCP is also available through RPM !!! (As an additional note, I have become aware of that there is some device proxying access to the ftp service at Mim. This might lead to failure to transfer large files. If you observe such problems, try connecting to Mim at port 10021 instead, which is an alternative port for the ftp server, and which circumvents the proxy.) 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.

All gone silent

by mark＠wickensonline.co.uk

Greetings Just checking I'm still subscribed? I have just started trying to give my emulated systems a little TLC to get them reconnected. I need to find out why my Raspberry PI based bridge isn't responding, it has run faultlessly in the basement for years and years, but something is amiss.

Area 23 temporarily offline

by Mark＠Misty.com

Hi, My power has been out since a severe storm, maybe tornado, passed through 7/21 afternoon. My hecnet router is not on generator power, so if any of my peers notice my absence, this is why. Mark -- Mark G. Thomas <Mark at Misty.com>, KC3DRE
