30 May '24

Can someone help out here with this Linux distro on Mac question? Please cc: almastrauss(a)outlook.com on any replies, thanks! Begin forwarded message: Date: Thu, 23 May 2024 10:00:18 -0500 From: Alex <almastrauss(a)outlook.com> Dear Sirs: I would like to migrate from macOS to Linux, and would very much appreciate it if you could please recommend me the most stable, fast, secure, and user-friendly Linux distribution to install on my Mac mini 2012 (https://support.apple.com/en-us/111926) computer based system comprising of: · 2.3GHz quad-core Intel Core i7 CPU · 16GB (two 8GB) of 1600MHz DDR3 memory · 2TB SSD · Logitech Bluetooth Easy-Switch Keyboard K811 (https://support.logi.com/hc/en-ca/articles/360023464673-Logitech-Bluetooth-…) · Logitech T651 (https://support.logi.com/hc/en-ca/articles/360023466673-Logitech-Rechargeab… Trackpad (https://support.logi.com/hc/en-ca/articles/360023466673-Logitech-Rechargeab…) · HP ZR30w monitor (https://www.hp.com/canada/products/landing/monitors/files/ZR30w-data-sheet-…) I am thinking along the lines of Ubuntu or Linux Mint (various desktop environments!), but it is extremely hard to understand which one is the most suitable for me… Or, perhaps, I am barking at the wrong tree?

MUUG Meeting, Tuesday, June 4, 7:30pm (In-person/Hybrid Meeting) -- Proxmox
by Gilbert Detillieux 28 May '24

28 May '24

The Manitoba UNIX User Group (MUUG) will be holding its next monthly meeting IN PERSON, on Tuesday, June 4th, at 7:30pm. Yes, that's the FIRST Tuesday of the month... Proxmox Virtual Environment With the recent acquisition of VMWare by Broadcom, many are looking for an alternative to closed source hypervisors. Wyatt has previously presented on Linux KVM virtualization, but without a management layer it can be clunky to use. [35]Proxmox offers a fully featured web based administration suite for KVM. It includes support for multi-host clusters, live migration, clustered filesystems, and more. Wyatt will give a tour of the Proxmox interface with a possible demo of VMWare to Proxmox migration. 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 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.

yay systemd-boot
by Trevor Cordes 21 May '24

21 May '24

Upgraded to F39 tonight (F38 just announced EOL in 1 week!) " Install an image using systemd-boot rather than grub With this release, systemd-boot can be selected as an alternative boot loader for testing and development purposes. " Fedora release notes has the above nugget. Yay, groan, another systemd feature-creep. Now grub is under attack? We really need a new way to boot? Ugh.

Use laptop as k/v/m
by Adam Thompson 13 May '24

13 May '24

This isn't a traditional KVM *switcher*, it lets you use your existing laptop as the keyboard/video/mouse for an existing system... I think. https://www.crowdsupply.com/techxartisan/openterface-mini-kvm If anyone gets one, let us know how it works! -Adam Get Outlook for Android<https://aka.ms/AAb9ysg>

Internet Message Format line length max
by Trevor Cordes 11 May '24

11 May '24

As a followup to my presentation where I mentioned SMTP line length limits biting me (one of the last slides): RFC5322 Internet Message Format https://www.rfc-editor.org/rfc/rfc5322.txt "There are two limits that this standard places on the number of characters in a line. Each line of characters MUST be no more than 998 characters, and SHOULD be no more than 78 characters, excluding the CRLF." I was slightly off, I said 1024 chars max. It's 1000 hard max, and "aim for" 80 chars max -- including the obligatory CR/LF. So the fogeys hard-NL'ing their text-only emails... you're doing it right and those young'ns are out of spec! :-) I still don't know why opendkim was barfing on ~500 char lines. One would think they would allow up to RFC5322 spec. Maybe DKIM spec or opendkim itself has a lower limit. I tried using the source luke but I couldn't quickly find the offending code, and since my bug was solved, I moved on. Upon further reflection, perhaps I should file a bug... Now, to go and make sure my custom headers are wrapping at 76...

Reminder: MUUG Meeting, Tonight, May 7, 7:30pm (In-person/Hybrid Meeting) -- DMARC/SPF/DKIM
by Gilbert Detillieux 07 May '24

07 May '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, May 7th, at 7:30pm. Yes, that's the FIRST Tuesday of the month... DMARC/SPF/DKIM (with one-click unsubscribe and alignment) Do you have anything at all to do with email daemons, managing email hosted by a third party provider, or manage DNS? Google just made your life a lot more complicated. (And heaven help you if you have anything to do with "mass" email sending.) Come on down to MUUG this month and Trevor Cordes will talk about all the technologies you must now implement to stay borg-compliant and ensure your emails don't get dumped into the Spam box or worse! We're talking DMARC, DKIM, SPF... And what's with this new "alignment" thing? If there's time we'll even go into one-click unsubscribe!

Emails sent to Shaw email addresses being blocked
by Montana Quiring 07 May '24

07 May '24

Hello, Anyone had any issues with sending to Shaw email addresses recently? I have a client that sends out smallish batches of emails once every week or so, and last week a number of them we blocked, but some went through. Never had this happen before. I confirmed with shaw that some of the addresses were active and receiving emails but that's about as helpful as they would allow themselves to be. Returned email (with email addresses made private): This is the mail system at host leaf102.mfilter.dimenoc.com. I'm sorry to have to inform you that your message could not be delivered to one or more recipients. It's attached below. For further assistance, please send mail to postmaster. If you do so, please include this problem report. You can delete your own text from the attached returned message. The mail system <-shawuser1-(a)shaw.ca>: host shw-central.mx.a.cloudfilter.net[15.222.199.59] refused to talk to me: 554 shw-ibgw-4002a.ext.cloudfilter.net cmsmtp 72.29.89.5 blocked AUP#BL <-shawuser2-(a)shaw.ca>: host shw-central.mx.a.cloudfilter.net[15.222.199.59] refused to talk to me: 554 shw-ibgw-4002a.ext.cloudfilter.net cmsmtp 72.29.89.5 blocked AUP#BL Reporting-MTA: dns; leaf102.mfilter.dimenoc.com X-Postfix-Queue-ID: 867B32645F X-Postfix-Sender: rfc822; sender(a)company.com Arrival-Date: Tue, 30 Apr 2024 13:00:50 -0400 (EDT) Final-Recipient: rfc822; -shawuser1-(a)shaw.ca Original-Recipient: rfc822;-shawuser1-(a)shaw.ca Action: failed Status: 4.0.0 Remote-MTA: dns; shw-central.mx.a.cloudfilter.net Diagnostic-Code: smtp; 554 shw-ibgw-4002a.ext.cloudfilter.net cmsmtp 72.29.89.5 blocked AUP#BL Final-Recipient: rfc822; -shawuser2-(a)shaw.ca Original-Recipient: rfc822;-shawuser2-(a)shaw.ca Action: failed Status: 4.0.0 Remote-MTA: dns; shw-central.mx.a.cloudfilter.net Diagnostic-Code: smtp; 554 shw-ibgw-4002a.ext.cloudfilter.net cmsmtp 72.29.89.5 blocked AUP#BL Regards, -Montana
