Network cabling (Cat 5e)
by Kevin McGregor 31 Oct '24

31 Oct '24

Is anyone handy at running residential Cat 5e? I have done it in the past, but I'm not super motivated to do it again, at least without help. Compensation of some kind is negotiable. I could just buy some 50- or 100-foot cables and run those... but that's $0.50/foot, locally -- or $0.20/foot (Amazon) or $0.08/foot (Amazon, bare cable). Thoughts? _______________________________________________ Roundtable mailing list -- roundtable(a)muug.ca To unsubscribe send an email to roundtable-leave(a)muug.ca

Hi all. I just noticed that The Long Con's site now has posted the lists of speakers and schedule of talks for the upcoming conference (Nov 2-3)... https://thelongcon.ca/speakers/ There are a couple current/former MUUG members presenting, as well as some other recognizable names from previous events. Tickets have been on sale for a while... https://www.eventbrite.ca/e/the-long-con-2024-tickets-1024450869127 I've got my ticket - hope to see some/many of you there! Gilbert -- Gilbert E.

[Board] Re: [RndTbl] Hardware and Engineering books
by Vijay Sankar 27 Oct '24

27 Oct '24

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

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

Re: Reminder: MUUG Meeting, Tonight, Oct 1, 7:30pm (In-person/Hybrid Meeting) -- Scripting Awk & /bin Diving
by Greg Manning 02 Oct '24

Wanted to attend the meeting this evening, but have to be at work for 5Am... :( Cheers ! On Tue, Oct 1, 2024 at 10:58 AM Gilbert Detillieux <Gilbert.Detillieux(a)umanitoba.ca<mailto:Gilbert.Detillieux@umanitoba.ca>> wrote: 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, October 1st, at 7:30pm. Yes, that's the FIRST Tuesday of the month... 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.
