Hardware and Engineering books
by Vijay Sankar 24 Oct '24

24 Oct '24

Hi, I have to get rid of a lot of engineering books (mostly old from 4 generations of engineers), computer tables, desks, couches, about a hundred 500GB, 1TB and 2TB hard drives, about 40 small SSDs, server rack and servers, book shelves, old desktops and laptops, iMacs and cables and so on. Please note that all but one of the systems have OpenBSD on them; not Windows or MacOS. If anyone is interested to pick any or preferably all of them, please let me know at vsankar(a)foretell.ca so that the list is not polluted. Thanks very much, Vijay Sent from my iPhone

Monitoring network traffic
by Kevin McGregor 09 Oct '24

09 Oct '24

I'd like to set up something that I can plug into my network that will track network sources, destinations, ports, packet types, etc. and allow me to graph the results. Presumably the network card and port will be in promiscuous mode to capture everything. What software should I be looking at? Free/libre software only, please. Also, what kind of hardware would be needed to support this (CPU, RAM, etc.)? I don't want to capture entire packets, just the key header info. _______________________________________________ Roundtable mailing list -- roundtable(a)muug.ca To unsubscribe send an email to roundtable-leave(a)muug.ca

apcupsd systemd /etc/nologin fail
by Trevor Cordes 02 Oct '24

02 Oct '24

As per my notice at the meeting tonight, here's the solution if you are using apcupsd with a new version of systemd and if it shuts your system down you cannot login after reboot. (Newest systemd 254.16 does not remove /etc/nologin on reboot, and the option to stop apcupsd from creating this file is broken.) It can't hurt to implement this right away even if you won't be using a newer systemd for a long time... this running cannot hurt anything if something has laready removed /etc/nologin. If you don't and you get hit by this, your only recourse is to login as root to manually remove the file. make a new script: /usr/local/sbin/apcupsd-rm-nologin ######## #!/bin/bash # apcupsd leaves /etc/nologin behind after reboot # and systemd no longer removes it # so do it here if [[ -f /etc/nologin && ! -L /etc/nologin ]]; then rm -f /etc/nologin fi ######### chmod 755 /usr/local/sbin/apcupsd-rm-nologin make a new systemd service file: /etc/systemd/system/apcupsd-rm-nologin.service ######### [Unit] Description=Makes sure apcupds power-outage shutdown nologin file is removed on reboot After=syslog.target [Service] Type=oneshot RemainAfterExit=no ExecStart=/usr/local/sbin/apcupsd-rm-nologin [Install] WantedBy=multi-user.target ######### systemctl enable apcupsd-rm-nologin.service _______________________________________________ Roundtable mailing list -- roundtable(a)muug.ca To unsubscribe send an email to roundtable-leave(a)muug.ca

Some of us could probably count on our hands the number of binary commands we actually run on a regular basis, but if we look inside we see thousands of installed binaries (2,691 on this editor?s system to be precise). So what the heck are all these and what are they for? Well what better way to find out than dive in head first and pick something at random. In the premiere of the /bin Diving segment, Gilbert Detillieux will randomly select a command from the /bin directory and attempt to learn how to use it. This will be an opportunity for some group participation as we attempt to learn a new command and do something useful with it!

90's mouse pad wanted (muug)
by Trevor Cordes 30 Sep '24

30 Sep '24

Does anyone have any new or excellent condition used mouse pad of the style that was ubiqitous in the 80's and 90's? approx 8x10" approx 1/4" thick (!!) cloth top <-- critical rubber bottom I've been poking around and they don't seem to make pads this thick anymore. Plus, most pads now are made of material that aids an optical mouse. My mouse has balls, and thus benefits from the cloth-style top (i.e. not shiny or smooth). If you have one (or 5) you want to get rid of / sell, bring it to the meeting, or let me know if I can come pick it up. I'm willing to pay $10-$25 each depending on the condition. Thanks! _______________________________________________ Roundtable mailing list -- roundtable(a)muug.ca To unsubscribe send an email to roundtable-leave(a)muug.ca

"bouncing" email from cmd line
by Trevor Cordes 19 Sep '24

19 Sep '24

If have a maildir file with a maildir format email in it. I want to "bounce" it (using mutt's terminology) to another address. By "bounce", I mean have it sent verbatim (with zero changes and zero new headers) to another email address. Only the envelope-to will be new (obviously). I need to be able to see the email exactly as the original user would have seen it, not "attached" or wrapped up in new headers. All from the command line, preferably the actual cmd line, not a TUI like mutt. Mutt can do this with the "b" Bounce command, but I can't figure out a way for mutt to get this single maildir format email imported via the -f option (which needs an mbox). I don't want to kludge/fudge it into mbox. I tried s-nail and sendmail -i piping but both seem to take the input to mean "body" instead of "headers+body"... though maybe I'm missing something with the sendmail invocation? If mutt can do it... surely I can do it from the command line!? Probably a magical sendmail option I'm not aware of...

another box. But I have more questions. When the prompt disappears are you running under X-windows? Or just a virtual console? If it is under X-windows and you are running a font server it is likely that your ipchains is blocking port 7100 or 7200 where the font server usually listens. And, yes, strange things happen if the Xwindows server can't get to the fonts. You might try changing to start up on runlevel 3 if you normally come up under runlevel 5 (Xwindows). Log on and test out your ipchains without Xwindows. On Mon, 14 Jan 2002, Raymond J. Henry wrote: > It hangs, but does not lock up. I can ctrl-alt-del the machine, and it will > reboot.

MUUG mailing lists are back up
by Trevor Cordes 13 Sep '24

13 Sep '24

The server upgrade went well and everything should be back to normal. Total server downtime was around 7 hours. The mailing lists took a little longer, about 2 days. The muug.ca server is now running Debian 12 and Mailman 3 (runs the emailing lists). Mailman 3 (mm3) is a complete rewrite and rearchitecture and redesign and there may be some teething pains. You should still be subscribed to the mailing lists you were prior to the upgrade. No further action should be required on your part and you can send emails to the lists as you always have. If you want to poke around the new mm3 web system, you can access the new mm3 web UI here: https://muug.ca/mailman3 You may be able to login to the new interface using your existing email/password. If you cannot, try the "forgot password" option using the email address you are subscribed under. You might also be able to make a new account and tie it to your existing subscriptions by signing up with your subscribed email address and a new username/password. mm3 seems to automatically tie it to your existing subscriptions. If you get really stuck, post your question to the roundtable mailing list, or you can email us at board(a)muug.ca, or myself directly with "MUUG" in the subject. 99.99% of the existing email list archives should be intact. You can access them by clicking "Archives" in the top navbar of the url above. The UI seems a bit quirky, and the import clearly wasn't perfect, so YMMV: we'll see if it behaves better as new emails are sent to the lists. If something seems blatantly broken (like broken links), let us know. _______________________________________________ Roundtable mailing list -- roundtable(a)muug.ca To unsubscribe send an email to roundtable-leave(a)muug.ca

Reminder: MUUG Meeting, Tonight, Sept 3, 7:30pm (In-person/Hybrid Meeting) -- lighttpd & Sublime Text
by Gilbert Detillieux 03 Sep '24

03 Sep '24

A reminder that the MUUG meeting will be this evening, both in person and online... The Manitoba UNIX User Group (MUUG) will be holding its next monthly meeting IN PERSON, on Tuesday, September 3rd, at 7:30pm. Yes, that's the FIRST Tuesday of the month... Fly light!, plus Sublime Text Kevin McGregor will provide a gentle introduction to the lighttpd web server. "lighttpd (pronounced lighty) is a secure, fast, compliant, and very flexible web server that has been optimized for high-performance environments. lighttpd uses memory and CPU efficiently and has lower resource use than other popular web servers. Its advanced feature-set (FastCGI, CGI, Auth, Output-Compression, URL-Rewriting and much more) make lighttpd the perfect web server for all systems, small and large." For our mini-presentation of a "desktop app," Brad Vokey will do a quick demonstration of his favourite GUI text editor: Sublime Text - "Text Editing Done Right." Sublime Text is a fast, mature, light weight, beautiful, customizable, expandable, cross-platform, "shareware" text editor. Brad has previously written about Sublime Text in the MUUG 2021-06 newsletter (page 5), and he will now give us a quick intro into some of it's features.
