    Certbot came with a systemd timer running twice a day (0, 12 +12h random) that only renews –iirc– when the certificate has 30 days or less to live. Also I looked it up and my (version 6.7) Certbot neither mentions the option with the --help option, nor in the manual (where there is just one instance of “profiles exist, no other details given”).

    So they probably need another way than a random blog post when they want users to use (or even just know about) that option…

    It’s been pretty much a set-and-forget experience

    Yeah, that’s what it always has been. So no need to change anything unless they make it the new standard on their side with an update…





  • Not OP, but it’s two-way TLS. It’s not only your server providing a certificate to prove it’s the real thing and not just some men-in-the-middle device or your connection for redirected, but the other side of the connection using a certificate, too, to show they are actually the devices allowed to communicate.

    So this basically reverts the security. You are no longer trying to filter out access attempts when they show questionable behavior, but completely reject anything unless it’s explicitly authorized. Which of course only works when you or (a small number you can manually manage of) others access that stuff from fixed devices that you can set up properly.

    PS: For me fail2ban does basically something similiar. I have several web interfaces exposed via reverse proxy. But I barely ever use those interfaces manually; normally it’s via apps that access the services via that web interface. So things like failed authentifications or misstyped passwords don’t happen (unless when setting up something new maybe and then I’m there to unban a device manually if I screwed up). So fail2ban is set up to aggressively bans IPs for hours just for a single failed attempt.

    That’s keeping all those spammy bots looking for easy targets away very effectively, yet completely invisible for my legitimate use. After all that’s always the core issue: security vs. convenience. You build the best possible security that also doesn’t overly interfere with your normal use. Also the reason there is no on-size-fits-all solution because it’s about your use-case.







  • Just google the term

    Yes, please do.

    The actual notion of “security through obscurity” (that will surely come up on Google if their AI bullshittery hasn’t screwed up completely…) for Linux is insane because open source is the polar opposite. By that definition proprietary code is actually much more linked to the concept.

    The often more unprecise and colloquial usage I thus assumed you were using doesn’t apply either, for the reasons I summarised.

    So which imaginary definition of “security through obscurity” are you using and assuming that it will come up on Google when none of the real ones makes any sense?



  • There was never an actual notion of “security through obscurity”. LInux runs the complete Internet and most coporate server infrastructure. That’s where the actual money is.

    People hallucinating that Linux is something obscure simply have no clue and confused their home desktop for real computing. Windows desktops are constantly targeted not because they are -unlike Linux- so wide-spread but because they are already insanely insecure. They are the low hanging fruit where you can cobble together some cheap shit and will still find million of PCs vulnerable. If you want to find a Linux comparison it’s definitely not server or desktops but cheap IoT devices not having seen an update (or any security to speak of) for many years.

    For reference: We are talking about guests in a virtual pc escaping it’s container. That’s not something obcure. That’s basically all cloud hoster’s whole business model, thus the reason Google pays a lot of money for finding such exploits.
