  1. Cloudflare Turnstile is garbage. If you use it, you will turn away Safari 26 users.

    The troubleshooting process can get Safari users to a page where CF admits that they are requiring browsers to be fingerprintable.

    FUCK THAT.

    There is NOTHING online that is so critical that I will knowingly give a consistent fingerprint of my browser to Cloudflare. They are not an ethical actor. They absolutely cannot be trusted.

  2. Just ran out of brainpower for the day trying to fix WTF a dev w/root on a production box did to deploy a #uwsgi application. Dev in question: no longer available. Apparently he didn't know there was a EL package available or how the “Emperor" rig works, so the app needs to be started by hand on every reboot. This was not a documented fact.

    I failed to hack up a fix. The Emperor kept cursing the application instance. I like the absurd terminology, hate the documentation...

  3. Oh. Huh. Imagine that….

    The .org root DNSSEC is gerbusterficated or in transition or something.

  4. dnsviz is being cranky for me. Everyone else stop using it for the day, OK?

  5. #FreeBSD #HotTake: Even though everyone with deeper #firewall juju than myself says #pf is better than #ipfw, so I guess it must be, I still like knowing my rules by numbers that don’t change. Plus I have tools written over many years around ipfw and would need to totally redesign them conceptually for pf. I don't have enough working years to do that.

  6. It seems to me based on mailing list traffic like a lot of people are seeing the free side of MS email (outlook.com, hotmail.com, etc. not paying customers on ms365) doing what it so often does today: mystery rejections and dropping mail on the floor.
    I assure you: if you're getting bounces because of this, your mail admin knows that it is happening and has NO WAY to address it.

  7. I never ceases to amaze me that mail systems do this shit. I know it was a thing with Sendmail but most of us have moved on or at least fixed the stupid mailer flags.

  8. It’s a rhetorical Q.
    It’s almost a miracle that it was found.

    It’s also why I do a paranoid level of consistency checks on every #SpamAssassin release. Our definitive repo is in Apache SVN, so we don’t have precisely the same vulnerability as libxz had, but I still verify that no matter how one gets the source, it is identical to what we've checked in.

  9. I’m almost at the point of just installing the relevant software on the bare metal host (already doing email…) like it’s 1999 and I only have one box.

  10. My best "rubber duck" is whatever public support fora exist for whatever I'm bloodying my forehead on. I rarely actually get useful responses, but just asking does something, sometimes.

    e.g. forum.opennebula.io/t/debuggin

    I'd been fighting this problem for many weeks, making little progress, largely because I didn't have decent time focusing on it. This morning I hit on the right places to look and found a huge mess underneath, but at least I fixed it.

  11. The people committed to DDoSing the #Apache #SpamAssassin RuleQA server seem to have substantial resources. I’ve blocked a lot of them, but they keep coming, asking about things like the May 7 2017 performance of a single rule in one contributor's stats. Not stuff real people want.

    Of course, there's a resource they do not have. Our sysadmins, both those employed by #TheASF to watch all of our infra and the volunteer cadre focused on SA. We'll keep whacking the moles...

  12. Well then, I guess I’ll have to replace that disk…

    Except it’s a virtual disk, and should NOT be doing that. None of the other umpty-zillion VMs in that zone are showing trouble. Only this one. And the 3 other instances I launched before based on the the same original image, provided as a pre-built one for #OpenNebula from the #Alma site. On different physical hosts.

    I am pondering how the content+config of system image could lead to this. sysctls?

  13. Is it really possible for svn.apache.org to be down and only the #SpamAssassin utility host and me to notice?

    #TheASF #SpamAssassin #Sysadminnery

  14. #TIL: #ipfw’s “me” does not include the local network's broadcast address.

    I know this because I’m building the bespoke packet filter for a new system (to characterize+quiet its real background noise) and had a long WTF session because I missed the last octet.

    #Sysadminnery #FreeBSD #InfoSec

  15. This sounds so much worse than it can actually be, given that I have no alerts on anything being down…

    I mean, “entire IBX" means the whole damn building and “out of service" seems like it would need to be a smoking crater.

    #Sysadminnery #Equinix

  16. Currently have a few dozen machines needing various upgrades/migrations:

    CentOS7->Alma9
    CentOS8->Alma9
    FreeBSD13.2->13.3
    FreeBSD13.3->14.1
    FreeBSD14.0->14.1

    As these all have extended ‘paint drying’ sub-tasks, it is no problem at all to be doing 2-4 of these simultaneously. There is no way I could lose track of which is which and how each one’s sequencing is going.

  17. I'm happy to announce the release of ASF SpamAssassin v4.0.1. This is a bugfix/anti-bitrot release, adapting to the latest Perl & dependency updates & sanding down some corner cases, e.g. it can once again be built from source & fully tested w/o wizardly effort on Windows with recent Perl.
    Sidney Markowitz (our PMC chair) acted as release manager for this release.

  18. #PSA When using that crazy brain-transplanter leapp, it is important to have a big enough braincase. Half a GB of RAM is inadequate. It results in midstream OOMs that are handled badly and can result in a completely insane system.

  19. LB: As someone who was an unwitting witness (grunt L2 support sysadmin) at the purported birth (or conception? courtship? lusty leering?) of "#Agile" at #DaimlerChrysler, I have never been able to take it seriously.

    That legendary payroll project was a total clusterfuck that never fully deployed. Pilot users were back-migrated to the old mainframe tool. When I heard years later that it was supposedly one origin of "Agile" development I thought I was being #pranked.
