[Board] Re: [RndTbl] Hardware and Engineering books

Caution! This message was sent from outside the University of Manitoba. Hi, I have some 2-port gigabit NICs and USB keyboards (unused). Will those be appropriate as door prizes? All the software engineering and security and telecom books that could have been good door prizes (were signed by the authors etc) were all given away already. Also, someone is planning to come over this weekend to take all the cables and SSDs, switches, old laptops and desktops and such. But I still have a fair amount of engineering books (from the 1930’s onwards). If any of those are appropriate as door prizes, you can have those as well. You’re welcome to come over and take a look. If your schedule permits, please let me know.

Hardware and Engineering books
by Vijay Sankar 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

Scripting Awk Kevin McGregor will provide a short presentation on some use cases for Awk in shell scripts. RTFM: /bin Diving Have you ever noticed how many things are in your /bin directory? 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! Where to find the Meeting: Fortress Software Inc., 350 Keewatin St -- Unit #2 We have a new in-person meeting location now! Brad Vokey has graciously let us use his work office for our next in-person meeting. The meeting room will be open by 7:00 pm, with the actual meeting starting at 7:30 pm. If driving, enter the lot using the most north east entrance and drive around to the south west corner of the building (see route in map detail on poster linked below). You can use any of the free, ample, and safe parking spots that say "reserved" in front of units #1 through #4 before entering unit #2. Bus stops #30814 and #30880 (route 77) are only 150 meters away. The last bus leaves for Polo Park at 10:15 pm and for Garden City at 10:31 pm. Logan Ave. bus routes #19, #26, and #27 are a 600 meter (8 minute) walk to the south. For those unable or preferring not to attend in person, the meeting will also be available online, using BBB as usual. Stay tuned to our muug.ca<http://muug.ca> home page for the official URL, which will be made available about a half hour before the meeting starts. (Reload the page if you don't see the link, or if there are issues with connecting.) The group now holds its meetings at 7:30pm on the *first* Tuesday of every month from September to June. (There are no meetings in July and August.) Meetings are open to the general public; you don't have to be a MUUG member to attend.

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...

None

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
